Building a Low Energy Storage Server for your Office/Homelab

hello again everyone you guys have asked for more home lab videos so be careful what you wish for because that's what you're getting in this video I want to talk about the new storage server that I'm building that it's actually going to replace my PowerEdge r7 10 I'm going to tell you guys exactly why I made the decision to rebuild it the parts that I decided to go with what my goals are I'm going to go through the entire process of replacing my storage server and you guys are going to see the entire process in this video so as you can see in front of me right now I have all the parts that I need to build this server but before I show that I'm going to talk about what my goals are in this project and then I'm going to go ahead and show you each of these parts individually and then I'll build it and then show you the final product so I'm going to go ahead and clear my desk and then we'll go ahead and talk about the goals so there's a few reasons why I decided to rebuild my storage server there's nothing wrong with it a PowerEdge are 710 well that's a pretty good server you can get one for a pretty good price on eBay and they're really stable so what's wrong with it well there's several things that I wanted to accomplish in this project now the first lesson that I learned about home lab is don't be impulsive about buying whatever comes available first if you plan on buying you know physical servers again there's nothing wrong with in our 710 it's a great server but you know for one thing it's kind of loud it uses more power than I would like I'd love to have the servers in the studio so you guys can see it in the background I mean how cool would that be if I had my server rack in the background I can't do that because it's loud as heck and there's no way you would even be able to hear me talk so you know you want to do some research when you go and buy servers and I didn't do that now the servers I have are fine but I decided to go a different direction so let's put aside the fact that the server rack is relatively loud for a moment and focus on another reason that I'd like to talk about and that's power usage now to be fair the electric cost where I live they're not astronomical some areas in the world I mean power usage cost more in some places than others and in this area it's not that bad but I don't want to use any more power than I absolutely need to because you know the more money you saved the more money you could spend on cool stuff and cool gear right I mean to be fair the elephant in the room is that I've probably spent more on this hardware then I'm going to save in the power usage and it's going to take me quite a long time to break even but it's much more than that I basically want to be as green as I possibly can and this is just one step in the process and I don't want to waste power I think that this is going to be a better fit and overall you know there's several smaller reasons that have gone into this decision that I won't bore you with but I wanted to give you guys you know the higher level details of why I decided to do this and besides it's a fun project to build a server and I think ultimately I'm going to be happier with something that I've built myself then something that I sourced from either nothing wrong with getting home lab gear from eBay but I think for me personally I want to be able to build every component and it's just going to be fun and I think you guys will probably enjoy seeing it as well alright so before I get to the actual build I wanted to show you guys a few things first so first of all this is one last look at my r7 ten because as soon as this new server gets up and running this one's going away so I've shown you this server before we currently have an L 50 630 CPU in this R 710 that's the CPU that powers my FreeNAS unit and you can see that I'm not really utilizing it all that much obviously when I'm doing some kind of a cloud sync or some kind of work that will jump up but it never really seems to get all that high if I scroll down a bit here you can see that I have one point six terabytes free if I go over here to storage and then pools you can see that we have about an 8 terabyte volume here now the new volume once again everything built will consist of 4 6 terabyte drives and that's going to give me 12 terabytes of usable space if you take into consideration that 2 of the 4 drives will be used for parity so I guess what that means is well this is going to be bumped up a little bit once I get everything built but I wanted to show you guys this server one last time as a point of comparison against the new one once I have it though now the next thing I want to show you guys is this right here this is the Dell remote access controller or idrac screen and this is basically a console on Dell servers you can log into to do various things and you know what this is really old-school it requires Java just to do a Virtual Console and I think that's lame because I don't really want to install Java just to facilitate that what that used to allow you to do and will still allow you to do if you manage to get Java integrated in just the right way it'll allow you to remote control your server and even boot it from an ISO file it's actually pretty sweet but again it's old and it's a little bit long in the tooth here and it does we're Java so it has to go but specifically what I want to show you is if I go here to power monitoring on this page we can actually see how much power usage this server is using right now and to be honest 126 watts that's not all that bad but it could be a bit better now if I scroll down a bit we can see that right here it actually peaked to 204 so it does fluctuate a bit based on the load but at this time of night there's really not a lot going on although starting at about midnight the power usage is actually probably going to go up because that's when all of my backup jobs start kicking off and those are encrypted so it does take a little bit of CPU power to get those backups done but again this isn't using an extreme amount of power but I do feel it could be better and that's one of the goals of this new build that I'm going to be putting together but what are we actually building so the motherboard that I am going to be putting in the new server is this one right here here we can see the entire model number of this board and then we can also get some specs for this as well and this product page it tells me that it has an Intel Atom c3 seven five eight CPU if I'm not mistaken there's a bug in the C 2000 series that can result in breaking your motherboard so that's one reason why I wanted to go new I didn't need something brand new but I certainly didn't want to buy something that was going to be possibly bricked in here we could see the CPU has a maximum rated power draw of 25 watts which is actually going to be more power efficient than my r7 ten and you can get some more specs here like how much ram you can actually put on this motherboard I'll have a link to this motherboard in the description below this video but we can also compare the CPU side-by-side so here on CPU world I plugged in the model number of the CPU in the freeness currently and also the one on the one that I'm building so again the new server is going to have this Intel Atom C 375 eight CPU and then my current free now server has an L 56 CPU and there's going to be some pros and cons here because the board that I chose isn't better than the previous one in every category in fact the r7 10 might still actually outperform the brand-new motherboard in some areas but that's not really important to me because again my goals are to have a more quiet data center and also to have more power efficient resources as well and the new motherboard definitely delivers that as you can see right here it tells me that the CPU and the new motherboard is 38 percent more efficient than the old one and if I scroll down a bit here we get some fancy graphs so you can actually see how the two CPUs differ from one another so the blue bar is going to represent the Xeon l56 30 that's in the r7 10 while the green is going to represent the new Intel Atom C 3 7 5 8 which is on the new motherboard now as you can see here they both have 8 cores that's pretty cool but we can also see here that the l56 30 actually has a higher operating frequency than the new one but that again that's not really something that matters to me but we're going to see here that we have more cache and then here we have actual better thermal design power on the new motherboard so according to this it seems like it's going to meet my goals here we get some pros and cons so to be honest I mean this is a significant drawback right here that might sway people to avoid this particular motherboard as it states you really can't replace the CPU on this motherboard that's true it's built-in so if the CPU goes or the motherboard goes they both go and I did understand and I do acknowledge that risk and I understood that before I bought it it really wasn't something that I was concerned with because I didn't really feel like there's really a big chance of that happening there's a bigger chance of a hard drive failing in a server like this than the motherboard but again you have to weigh the pros and the cons now the atom actually has more actual course but as we see here the Xeon is upgradable so that's a pretty significant benefit of the Xeon and the r7 10 in fact the l56 30 CPU that's in there right now is not even the one that it came with I did downgrade that the L stands for low power usage or something like that L Series Z Ron's use less power than normal Xeon so it would actually be using a little bit more power had I not downgraded the CPU but again I already understood all the pros and cons and well this is the direction that I decided to go so with that out of the way let's go ahead and build this server so now what I'm going to do is show you guys each individual component and then we're going to go ahead and put it together so first of all if you want to build a server you'll definitely need some sort of chassis to put the parts into otherwise it's just going to look weird and for that I decided to go with this D 400 case from ISTAR USA now before today I've never owned any of their products so I don't really know what to expect beyond the reviews that I've read but of all the cases that I found on Amazon I just decided to go with this one it looks really cool it's going to fit my needs it's big so it has room for airflow and lots of hard drives definitely something you'll need for a storage server and it seems like a good fit overall and you'll know by the end of the video how I really feel about this case but it's so far based on what I've read it seems like a good fit for my use case in addition to that we are also able to open up the front so I'll go ahead and do that we have two front panels that open right up which is pretty neat so all in all it seems like a good fit for a storage server so I'll be putting all the parts in here in just a moment but next up I'm going to show you guys the power supply so here's the power supply that I've decided to go with this is from an tech it's an 80 plus bronze power supply and it's considered a green power supply it's 80 plus bronze so it's supposed to be more power efficient and have a reasonably quiet fan now I know some people get very passionate about the power supply choice I'm not really passionate about that kind of thing because the way I see it as long as it powers the computer it doesn't burn up and it's not super loud I'm generally fine with it so this is the direction that I decided to go this power supply right here so if you have any opinions on this choice go ahead and let me know in the comments below but I won't spend a whole lot of time talking about the power supply because at least to me it's not really something that's very exciting but here it is for better or worse and I'll definitely know how I feel about it when I get the build completed but I think based on the reviews it should be a good choice and speaking of not very exciting I have this generic brown box right here you can probably guess what's inside yes that's right this is a hard drive I have four of these I decided to go with the Seagate iron wolf Drive and this is a six terabyte drive and with four of these I'm going to end up with about 12 terabytes if you account for two drives being parody so you know that's going to be enough storage for me because I don't store a ton and I could have gone with the 8 terabyte drive but I did you know spend quite a bit of money on the other part so I wanted to kind of cut cost somewhere and I think that this is going to be reasonable I've done some reviews and found that the Seagate iron wolf drives are considered to be a good choice for a Nass unit nowadays so that's why I decided to go along with this I've mentioned earlier in the video that one of the goals was being very power efficient I want my Nass to use as little power as possible and that's when I found this right here I did some research and to be fair this one is a little expensive this is a Super Micro motherboard it's supposed to use a very low amount of watts I guess we'll see when I measure it once we get it put together but it has a built-in Intel Atom processor it has eight cores just eight cores and eight threads but for me that's enough because I'm not like using this nest for a bunch of users or anything like that at the end of the day is just me and eight cores is probably overkill I would have saved a lot of money by going with the four core version but I decided not to because from the reviews I've read it actually has additional slowdown because of some way that it shares resources via the same bus and this version it's not that I needed eight cores it's just that it wasn't going to have the same performance penalty and it still does actually save a lot of power now the processor is built-in it's an all-in-one unit so unfortunately the problem is that the motherboard dies well everything dies so yes I know that is a problem but from what I have researched I was unable to find another solution that was going to offer the same power savings so that's why I decided to go along with this and again it is an Intel Atom board you have to be careful with that because there are certain Intel Atom processors that have a bricking issue based on my research and saying the word brick and reviews is enough to make me stay away from a motherboard believe me and this one should not have that problem so that's why I decided to go along with this now normally I would tell you what the model number is and everything I'll put that information in the show notes below this video I'm just too lazy to read the model number it's really long and I mean it can't be good marketing to have a long model number but from what I've heard and the reviews I've read this should be a good choice for my storage servers so this is what we're going to be putting in the server and I'm gonna do a quick unboxing this isn't really an unboxing video or anything like that but let's go ahead and take it out of the box so what do we have in here we have a parts list nothing too exciting there and you get some documentation about the headers and things like that basically standard-issue motherboard stuff and a plethora of cables we have some silver SATA cables Wow I have never actually seen silver SATA cables I guess I've never really cared too much about SATA cables as long as they have good reviews and they're not going to flip some bits they're generally fine and then some we have some red ones of course we have the backplane plate another SATA cable another SATA cable I have guys a ton of sanic cables now is if I didn't already have a whole box full of these things now I have a bunch more and then the motherboard itself kind of takes all the foam to get it out and here it is it's very small this is mini ITX so again I'm going for power usage efficiency low power usage basically and you know everything's integrated on the board it's a very small board and and you know the chassis this thing is going to look extremely small inside the chassis but I'm ok with that more airflow so you'll see this motherboard a lot better in the retin the remainder of the video when I actually go ahead and put this in the case and start building it but this is again a Super Micro eight core Intel Atom motherboard so I'm really excited to get this thing installed and of course we will need some RAM in our server otherwise it won't even boot so I decided to go along with this it's a stick of Samsung ECC memory it's only 16 gigabytes I figured that's enough for now again I'm only one user I'll probably buy another stick of RAM just like this one because with only one stick a ram I can't benefit from memory interleaving but for now I think this is a good starting point Volume I decided to go with this kingston SSD right here and this is an a 400 SSD it's nvme as you can see it's a hundred and twenty gigabytes which admittedly is overkill because this only needs enough room to store the operating system and this is the smallest cheapest one that I can find I wanted nvme for the boot volume because I want the server to start as fast as possible and I also want the user interface of the NASS to be as fast as possible as well and I think that this will actually do the job just nicely so the problem with the case one of the biggest weaknesses is that while it does have doors on the front that open they're practically useless because there's no harddrive mounts in those bays at all so you still have to mount the hard drives to the inside of the case so to fill that void and to fix that flaw I decided to buy this now I actually have four of these one for each of the hard drives this will give me the ability to easily slide in or out a hard drive in the front it's a mobile rack and all it is is a five and a quarter to a three and a half inch adapter that allows you to put a hard drive essentially where a optical drive would normally go now it sucks that the case doesn't already come with a way of easily removing hard drives are adding hard drives but this right here is actually going to compensate just nicely and give me the functionality that I feel the case should have in the first place I also mentioned near the beginning of the video that one of the things I wanted to achieve with this case is to make it as quiet as possible so I decided to go with this Noctua Redux fan right here so I'll go ahead and take it out of the box and as you can see it's just a simple fan and here's the fan itself I mean nothing too surprising here it's just a fan but you know these are supposed to be the quieter fans and I decided to give that a shot and see if that's true so this is the fan that I'll actually be mounting into the case all right so here's the top view of the case and what I'm gonna do is just open it up and show you the internal side and then I'm going to install the individual parts now I apologize I wasn't able to get the camera up high enough so the camera is going to look a little weird here but you know I don't have the greatest tripod in the world so I'm trying my best and there's some screws on the side I'll go ahead and remove those and you can't see it but there's one in the back as well so now we can start to get a look at what's inside this case so we weren't able to see it but there was a brown box in the back side of the case here it is right here let's see what's inside yeah let's see you have a bunch of screws you have some slot covers and some zip ties basically standard stuff for a case this piece of paper here what does this say some kind of inspection sheet I guess yeah nothing too exciting so I'll go ahead move this around a bit you have all the various cables that are going to be connecting case to the motherboard I'll get these out of the way so next I'm going to attach the standoffs for the motherboard so next I'm going to go ahead and attach the back plate and here it is right here now a quick word about this I found this a little annoying you'll notice that some of these are punched out and then some of them are not I had to be selective over which ones I punched out it appears to me that this must be some kind of generic back plate that might be used for different motherboards so you definitely don't want to punch all of these out only the ones that you actually have to otherwise you'll be letting some unnecessary air into your case just go ahead and line it up to your motherboard and just make sure that you're punching out the right ones so I'll go ahead and put this in the case and again I'm sorry you weren't able to see that I don't have the best tripod in the world so you know doing the best I can with what I have next up we have the motherboard I'll go ahead and try to get this into frame here and here is the Super Micro motherboard that I decided to go with and again the model number will be in the description below this video but this is an Intel Atom motherboard again eight cores we have four RAM slots here and we have four SATA slots that I'm able to see now this does have a cooling fan even though this is a system-on-chip kind of processor and not all the models have this I believe if it has a plus in the name it has a cooling fan and if it doesn't and well it doesn't I'm not 100% sure of that but it does appear to be the case now interesting right here we have a USB 3 port which is pretty cool because you know FreeNAS which is what I use can be installed on a flash drive but if you did decide to go that direction you can have your flash drive inside the case this is actually kind of common with servers if you have a flash drive that you don't want removed then you could go ahead and attach it right here inside the case and you don't have to worry about the flash drive being disconnected then on the back we can see the various ports that we have there's a dedicated port for IPMI for remote management we also have four other NICs as well these are gigabit ports as I understand it of course we have VGA as well but this is a server so I'll probably never be using that you know aside from the initial power on of course of course we have some USB ports on the back as well nothing too surprising there and if you're curious what the underside looks like well here it is and you know when it comes to the other components on the motherboard we have the standard suspects so I'll go ahead and I won't talk about every single component but you know here's the motherboard so hopefully this was a good choice I'll go ahead and put in the case now I'll see if I can get this moved forward at least a little bit so again apology is about my tripod but at least you can see how little this motherboard is compared to the rest of the case it's tiny so now I'm going to go ahead and well screw it in you okay so motherboard is in and for I'll go ahead and plug it in this is the fan that comes with the case I'm gonna give you guys a quick look at that this is the rear of the case right here you can see the fan that it came with there's room for another fan if I'd like to put in another fan of course right here we have the finished back plate with the proper air holes punched out again be careful with that so the motherboard is in now it's time to get the power supply in place alright and this is probably a better view of the case I probably should have went with this camera angle before but I guess you know can't change the past so let's get that power supply in so I'll go ahead and Center this so I just opened up the box and this is what it looks like so I'll carefully remove this out of the box and here's the power supply this is well can't say I've ever seen packaging like this before but I guess it's fine he's a paper around it that's weird and here's the power supply I'm just going to show various angles of it see what it looks like it's not a modular power supply I you know went the cheap route here so we have all these cables that I may or may not use but it's good enough for now so nothing too surprising so far okay so here's the other side I didn't show guys are curious go ahead and put this in the case you have to maneuver around this top bar I guess I probably could have just you know I'm screwed it and took it off but I'm lazy okay here we go you you all right so that's in go ahead and unravel some of these cables of our standard-issue motherboard cables here so let's get this plugged in so the power supply is in I'll worry about cable management just a moment I'm going to go ahead and switch gears and get the hard drives put in you okay so at this point I've gone ahead and installed the new server in the rack it's in a temporary position right now which is why I'm not going to show the rack at this point in the video I did power it on for a bit to check out the BIOS and things like that but the server is actually off right now what you're actually seeing on the screen right now is the IP mi interface so even though the server is not powered on I am able to basically connect to the console of the server so it does have enough power to run this console and that'll let me login and I can basically control the server from the LAN for some reason I wasn't initially able to access this console at all the default username and password is supposed to be admin and admin respectively but that didn't work and I also did some google searching and there's some variations of that none of that worked for me I actually had to boot the server and reset the password in order to access it so I'm not really sure why I needed to do that if it's a brand new board it really should be admin and admin that's also what the documentation for the board claims as well but anyway I am able to access it now so let's check it out and here we have the actual interface for the IPMI this is pretty cool so what I'm going to attempt to do is install FreeNAS that's what I've decided to go with via this console so that you can basically see the entire process what I've done off-camera as I went to virtual media and then cd-rom image I've entered the hostname of my existing current FreeNAS server and then the path right here to a Windows file share that currently has the FreeNAS ISO saved inside it and that I clicked on the mount button and then when I clicked on refresh status this changed right here to say there is an ISO file mounted so basically that means that it should actually work so I'll go to remote control and let's go to I KVM html5 click on the magic button here let's see what happens so my browser apparently doesn't support recording video that's fine I don't really care now obviously the server is not on right now so that's why you see nothing so I'll go ahead and power it on there we go so the server starting up and then when it comes up I'm going to press f11 for the boot menu in time takeout to wait till after the USB devices are detected if I'm not mistaken Jericho's ax says invoking boot menu so it should actually do exactly that and the first time the server started up it did take quite a while so if you get a board like this one is totally normal server boards aren't really known for a really fast boot but that's okay so anyway we have the boot menu right here and I've never actually done this before using media remotely to boot a server so let's see if this works so I'm going to go down here to I assume this is the right one virtual cd-rom I'll press Enter and I assume it's going to take a bit longer to boot from a network ISO file but here it is Wow look at this the freeness boot screen is right there so it is booting off the virtual CD drive that's pretty sweet okay so I'm going to go ahead and press enter on the first option install slash upgrade and it's asking me which hard drive I'd like to install FreeNAS on and by the way I know this is the Linux channel and FreeNAS is not a Linux solution but it's less about what I'm installing and more so about the overall use case because you could simply replace FreeNAS with open media vault or straight Debian if you'd like but anyway I'll press the spacebar to put an asterisk in the first option there that's the Kingston nvme SSD and I'm going to leave all the other hard drives deselected because those are the hard drives that will make up the volume for storage so I'll press Enter proceed with installation sure why not enter and I need to set the root password so I'll give it a temporary one for now boot via UEFI is fine and swap why not you okay so it looks like everything was installed so if all goes well it should boot into freeness so let's see if that happens then reboot it and here we have preen ass booting so so far so good all right as you see here we have an IP address and actually with my router slash firewall basically pfSense I don't even need to remember that because I could simply type in the host name which simply defaults to FreeNAS so let's go ahead and see if I can get in and sure enough we have a login page there we go I've successfully logged into FreeNAS this is the new server right here we're all set and ready to go now the next stage of course is for me to migrate all of my data from the old server to the new one so what I should actually do right now is create the pool with the new hard drive so I'll go here to pools and of course we don't have any so I'll click Add I'll create a new one for the name I'm going to give it volume one just like that now enable encryption [Music] let's confirm that then for the disk these are the disks right here that I expect to see the four that I haven't already used because the only other hard drive I have is the nvme drive which this is running off of so I'll just go ahead and select all of the drives add them right here and it is Auto suggesting rate z2 which is the option that I wanted anyway and it gives me the estimated capacity that I'll have right here ten terabytes or roughly ten terabytes which is actually more than I had in the previous pool now basically the reason why I don't need more than that is because I do archive a lot of stuff off-site so ten terabytes is probably more than I need I think I'll be fine with that and I'll click on create' and I'll confirm and I will download the encryption key for safekeeping just in case I need to recover data later did complete so I'll click done and now we have the actual pool right here volume one has been created that's pretty cool now I don't have any datasets here so what I'm going to do right now is start the long process of transferring data from the current FreeNAS the one that's running on my r7 ten to this new one this is the old server right here in this tab here we can see all the data sets that I have I'm going to click on tasks and then replication tasks right here I'll add a new task so source data set will be on this system and then I'll pick something very small to start out something that shouldn't take a whole lot of time I think this Clonezilla data set although it does have a decent amount of data in there it's probably the least data that I have or at least the smallest data set so different system username will be route I'll put in the password here and the new URL right here Bree nest home network dot IO I'll probably change that later create SSH connection apparently I needed to add this part here so let's try this again then here I'm going to go ahead and create the data set put the name in there save it we have that data set so back here on my old unit so I'm going to go ahead and fill out this information right here so I'll just call it sink Clonezilla to root for the user and we'll do the source that's going to be this one right here Clonezilla will do target you and then I'll go ahead and save it so now we have the Clonezilla transfer replication task so let's see what happens let's go ahead and run it the task has started current state is pending and it aired out unfortunately let's see why okay so apparently I need to change the option replication from scratch so that should be fine there we go I've been able the option I'll save it let's go ahead and run this again started says that it's running and it looks like it's actually transferring data that's pretty cool so I'm going to go ahead and let this run and then I'll come back and check on it later all right so it looks like it finished we have the log right here that shows me basically what all it did then over here we of course have the data set and right now it's it's telling me there's 127 Gibby bytes use but of course I didn't refresh this page yet what is refresh it and we can see now that there is some use of space in there so it looks like the transfer was in fact successful so off-camera what I'm going to do is just go ahead and migrate the rest of my data over to this new server so the build is all done it took me several days to fine-tune my new FreeNAS server and it took a while to copy all of my data from the old server to the new server but it's in the rack it's all done and I'm happy to report that this project was a complete success in fact my FreeNAS server is running at 55 watts give or take what I'm overlaying on the screen right now is the actual kilowatt meter that I plugged the server into so you can see what the actual power usage is on this unit and the good news doesn't end there not only am i benefiting from power savings on my new FreeNAS server I've actually managed to get the power usage of my entire rack down to just 140 watts on average and no I'm not kidding everything on my server rack equates to around 140 watts now how did I accomplish that well spoiler alert I've actually also built a new proxmox server as well that's also energy efficient and I've already recorded the footage for that video which I am going to start editing right now and I hope to get that video out as soon as I possibly can but with the new FreeNAS server and the new proxmox server I have a very energy efficient rack that's not going to be resulting in a very large electric bill now if you haven't already done so be sure you subscribe to my channel because you'll be the first to get notified as soon as I have the proxmox video out I can't wait to show you that build it's awesome but in the meantime what do you guys think of my free Ness build do you like the idea of an energy-efficient freenas server let me know in the comments below and if you have any questions let me know those as well and let me know what you guys decided to build if you have your own free now server what did you go with how did you build it talk about home lab in the comments below but anyway I hope that was helpful for you guys and I'll see you in the next video you
