Synology NAS Setup Guide 2022 #8 - Setting Up an iSCSI Target and a Storage LUN

[Music] hello and welcome back to another part of my series of videos where i'm going to show you how to make the very most of your synology nas with dsm 7. now in previous videos i have talked to you guys about setting up a mapped network drive for those of you that aren't aware a mapped network drive is a folder on your nas that you can see the net the network attached storage storage like this it allows you to interact with it on kind of a similar file folder level to what you're used to you can access the folders and the content and navigate the contents of that nas however map network drives are by no means the best the most optimal way in which you can interact with a nas there's lots of reasons for this ranging from the fact that some proprietary applications be they photo editing video video editing even some basic level applications aren't able to interact with map network drives in the same way that they can interact with the likes of your local os drive or a drive that's connected via sata now the answer to this is creating something called a london an l-u-n an alan is an area of storage on the nas that is visible and has the appearance of localized storage on your client hardware it also allows a greater degree of access and control and utility with the software on your system now on today's video i'm going to be utilizing this synology now as a ds 920 plus and i'm going to be utilizing dsm-7 i'm also going to be using the new san manager which is a rebranding and overhauled and improved version of the iscsi manager for dsm 76.2 uh sorry dsm 6.2 so a lot of the steps in today's video are still appropriate to dsm 6.2 also if you're going to be using a windows pc i recommend utilizing a tool known as iscsi initiator something that will become clearer later in the video why we're using it if we head back onto the user interface here we can see all of our options now in order to do this we're going to need to select the option lon we are going to create a target during this now for those who aren't aware whenever you hear the word um i scuzzy being thrown around in modern storage terms two words get thrown around that is target and lan now target is the direct point in which your storage can be reached and the lan is the area of storage there's more to it with than that but that's the easiest way to explain so in order to create our lan we can go ahead and click create along the way we will also create a target select create first give your lan a name i'm going to call this one dsm 7 lun we can give it a description if we choose but we also have to say where on the nas it will reside in terms of the volumes you've created then you have to give it an area of storage now this is going to be really important because not only are we talking about how big this area of storage will be and remember you're going to be utilizing space that already exists as a volume on your nas but in a moment we're going to talk about provisioning where storage is important so say for example we're going to give this one 100 gigabytes it's worth highlighting that after this we'll be asked if we want to use thick or thin provisioning now as you can see as indicated by the synology themselves a thick provisioning area has better performance whereas thin provisioning doesn't have the same level of performance but the difference is that thick provisioning is where if you select 100 gigabytes this lon will immediately take 100 gigabytes from the system it's trickier to expand and ultimately is a more fixed level of storage which is great for predictability and performance but less good if you want to increase the storage later alternatively if you select thin provisioning even though we put 100 gigs it is flexible in its approach you can change the amount of storage and also storage will only be allocated how and when it's used for me i'm going to go thick provisioning for performance but bear in mind the different settings may be useful to you and there's a lot more to thick and thin provisioning than that simple overview i gave you next up click next from here you have to choose which target you're going to utilize now if you haven't created a target yet an automatic one will be generated but if you have created alternative targets so you can separate all of your areas of storage in the connections you can create new ones if you have additional cards that have been added such as fibre channel cards or even other improved network interface cards they will also appear and you can choose between them after that click next and say who can access it do you want to make sure that all people can access it or only certain default users again you can configure those quite easily and there you go we're about to confirm our settings click done when you're ready and the area of storage for our lan will be created as well as the default iscsi target being created and there you go we've created our ice cutty target and we created our lan if we want we can create a brand new lan by cloning what we've got there or creating a brand new one we can delete this land for a new one if we choose or select edit if we want to change the level of storage an option that's open to us because of the provisioning we may or may not have selected based on how we go for it and after that we can add lots of zeros if we choose if there's the available storage on the nas and again as mentioned it is heavily dependent and its flexibility is heavily dependent on the storage area available as well as the permissions who can access it and more all of which can be configured on the fly now we've done that we have to make our way over to the other area of storage using the iscsi initiator real quick though let's go ahead and create another area of storage this one of 200 gigabytes and this one is going to use thin provisioning and we'll call this one lan thin so we can have a little look how they both compare click next utilize the same target as before allow all users to access it and click done and there you go we've now created a second one but this second one is thin provisioned so we can have a little look at those settings if we choose and as if we go in we can edit the lan and as you can see on this one we can change the capacity but it won't matter because we can actually create flexible provisioning quite easily and there you go it's all set up the way we want it to be and again we've got all the options for cloning and more along the top of the screen so now on our desktop computer we open up the iscsi target now on your other iscsi target all of this stuff here on screen will not be visible all of this stuff as you see is from previous lands that i've utilized so for you head up to the discovery tab from here click discover portal then enter the ip of your nas as shown in the web browser again there are other means of accessing an iscsi lan and again it will differ and be reflective of the way you have set up your nas but otherwise connecting directly to the ip ensuring that the nas and the pc you're utilizing on the same network will help again click advanced if you want to enable other settings such as the ip do you want to use certain adapters on your machine targeting the ip directly or are you going to enable chaps which is a form of password and authorization protection on there if it's already enabled within the nas apart from that we can go ahead and click ok and confirm the settings we've made here right so far now we've added that search target we can head back into the targets list and as you can see the 920 has now got an available target remember this isn't the storage area this is the target the portal to access it so select that one that's listed as visible but inactive scroll to the bottom and select connect if you want to create a multi-path connection so as multiple people can communicate tick that box and click ok as you can see we've now connected to the iscsi target the next thing we need to do is head into the storage manager of the pc now you can do this from the control panel alternatively head to the my pc or my computer icon and go to the top under the computer tab and select manage in the next window it will open up with administrative tools in the computer management panel from there double-click storage then into disk management and then from there you can see that the system has now identified two new connected areas that can be added as logical drives in other words drives that can be seen with the visibility of a local connected drive as you can see we've selected gpt do not select the mbr option as this is designed for your operating system and by selecting that it can screw up how you can connect with the machine but for now click ok and it will add these two drives so now they're visible as you can see there's our first and second drive readily available go ahead and right click them and select new simple volume or if you want to take advantage of spanning volumes or connected volumes for redundancy and protection you can use the other options but for now we'll create a new shared volume go ahead select an option in this case i'm going to go for the letter r for no reason we can name this if we choose we'll call this one thick click next and boom it's allowing it to be added and it will be available shortly as a visible area and again we can right click the next one repeat the same steps give it a name we're going for drive e we'll call this one thin for the hell of it click next and finish and it will shortly add this area of storage to your local pc as you can see it's now seen them and now when we head in not only do we have our c drive and the other connected drive i've got via sata but now both of the iscsi luns are visible on our local computer and we can interact with the nas with most of the software that would not have been able to see these mapped network drives remember in my dsm series in part one i showed you how to map a network drive utilizing the synology assistant tool finding the nas on your local area network finding an ad right clicking the nas once the system has finished searching and from there mapping network drive as useful as this can be it's still not as good as utilizing an iscsi target which has inherent performance extras on them but otherwise thank you so much for watching i hope you've enjoyed this video if you have do chuck me a like and of course click subscribe for further videos other than that thank you so much for watching and i will see you on the next part in this series on dsm 7.
