How to setup iSCSI on Synology NAS & connect from VM-ware ESXi - 826
ฝัง
- เผยแพร่เมื่อ 4 เม.ย. 2019
- Overview of what iSCSI is and how it is different from a NFS or SMB share. Setting up a new volume on my Synology RS1219+ and after that, a iSCSI LUN with a new Target,,, testing first from my Windows Desktop and then adding a iSCSI software adapter on a VMware ESXi host and making a storage volume for shared storages to all hosts to use. Finishing off with a speed test.

Even just 1$ a month, comes out to the same as Binge-watching like 400+ of me Videos every month.
My PlayHouse is a channel where i will show, what i am working on. I have this house, it is 168 Square Meters / 1808.3ft² and it is full, of half-finished projects.
I love working with heating, insulation, Servers, computers, Datacenter, green power, alternative energy, solar, wind and more. It all costs, but I'm trying to get the most out of my money, and my time.

I've sat and watched a few of your videos tonight including this latest one! Well explained, not too fast or slow and I've now subscribed. Keep up the great content!
Hi Brenton Crosby
Thank You very much! I do also interact and replay,, new comments and it may be a bit short,, many comments to get to,, Welcome Aboard!
Thank you for watching! :-)
Really cool, didn't know about multiple iSCSI connections. I've always thought that iSCSI was a 1-to-1 connection...
Be careful with what you are trying to do. The multiple iSCSI sessions is not for multiple server usage unless they are in a cluster just like the warning on the screen said. This means that unless you are running a cluster aware configuration which in the case of Windows Cluster is able to coordinate the writes, you can cause issues with data corruption/loss. For multiple server access scenario, you need to use SMB or NFS shares.
@@clouddeveloperio thanks for the clarification. So I must assume that two ESXi hosts without a vSphere coordination aren't suitable for such a connection
@@StefanoBettega It appears that ESXi VMFS is a clustered file system so it might work correctly because it locks the individual files but I would not recommend using iSCSI in a traditional file share sense or a disk to an operating system unless you have them configured using some sort of a clustering setup. Here is a link to ESXI + iSCSI for shared storage in case you are interested: 4sysops.com/archives/how-to-configure-esxi-6-5-for-iscsi-shared-storage
@@clouddeveloperio thank you very much for the link. I will surely try it! Awesome!
Hi Stefano Bettega
Thank You very much! Yes a cluster aware file system.

Hey, I decided to adress my ISCSI-Luns via die network-cards' features. They have full offload and can provide a lot of boost for your overall performance. I'm sure your IBMs have that feature aswell in your Network-adaptor's Bios

I was hoping to see some iSCSI storage that could be used on a VLAN. I have a VLAN40 for my test servers and wanted to create storage that can be used just for that VLAN40. Have you made any videos that have the storage available to a VLAN?
I never got to my vlan and seperate everything.
Hello, Thank you for the video. I have two esxi hosts, and SYnology rackstation 1619 with 1 Gig 4 NIC in both Esxi nodes and NAs 1619. Please let me know how to connect it physically (multipath). You have used 10G x1 interface for storage traffic right ? In my case DO I need to give IP address for two interfaces in NAS and connect it with Servers (1 to 1)? I have some doubts in physical connection.
Hi Vilbi Raju
Thank You very much! If I do this , you will get a video,, have not done it yet :-/

I do prefer nfs over iscsi. Less to configure and works just fine. Recent benchmarks shows that the nfs in some cases outperforms the iscsi, not much, but still. And I do prefer hosting nfs on my two jx40 s2 eternus (2x(12x4tb raidz3) in raid 0, 2x(12x500gb ssd raidz) in raid0) basically raid 70 and raid 50. Speeds are amazing on the ssd pool, but having some serious bandwidth limits, the freenas box has only 1x2 port, 10gbps mellanox network card shared for vm storage, private storage, diskless boot (pxe server for some client pcs and experimental things). But I do have parts ordered for the second freenas server which will act as active backup and will be there for redundancy, I'll firstly test out the iscsi server to see if it is worth upgrading to it :)
Hi Victor Shane
Thank You very much! I need to try booting a server from an iSCSI drive,, never got that up and running.
Thank you for watching! :-)
Can you make a video explaining how to backup a LUN ? For instance on my DS215j the Snapshot feature is not available in the iScsi setup - I have to use HyperBackup in order to backup a LUN
Hi Thomas de Vos
Thank You very much! Maybe,, I usually have a very small amount of data that is that important.
Thank you for watching! :-)
Hello, I am doing this same process but with synology I would like to know how to connect my dvr being in a different network than my nas, it connects locally but I try to do it remotely with my public IP and the routes do not appear
I am not sure what you are doing,, but you might have to setup a share or some FTP,,, something.
REQUEST. as there are problems with bootable sticks - Can you Pls tell us how to boot ESXi 7 from e.g. a Synology NAS Directory PLS ?
Maybe this will help : th-cam.com/video/VPuoQGoZDK0/w-d-xo.html
I am having a serious issue with SCSI on windows 10. When I am copying a file from my NAS to another NAS that has an iSCSI volume setup it keeps bluescreening and rebooting the PC with a Windows watchdog error. I can copy smaller files fine but when I go to copy larger video files in bulk it blue screens. I discovered this when I was trying to make a complete backup of the NAS so I could install a new drive and configure RAID. The NAS requires all drives to be removed a restart with no drives and then to have the new blank drives installed to trigger the RAID configuration. I can copy a single file successfully but I am not going to do that to 40,000 files. Any input or suggestions on this issue? I have had this on windows since I initially installed windows 5 years ago and it has not been resolved even in the new 2004 release..
That sucks,, I do not have any good sugestions,, :-/
Can I do this with an existing volume with data on it already? Or does it have to be unused volume? Thanks
I think You can do that,, be sure to backup any important stuff,, before trying. :-)
I have an iSCSI volume setup on my NAS and it gets stuck reconnecting. I have to go into the intiator and manually disconnect then reconnect for the drive to show up every time I reboot. Any suggestions?
In Windows, there is a thinky that you set then you create the connection, if you want it to reconnect.
@@MyPlayHouse I've got it checked but it goes into a reconnect state but never completes the reconnection. I need to disconnect and reconnect manually.
Nice :)

Morten hjorth sir, in frame 3:57.
I could see the web address and it says unsecured if that's any help.😉
Hi ralph ups
This is a local IP,, it not on the internet,, there are some ranges of IP,, that is for local use only and can not go in the internet,,, 192.168.xxx.xxx is one.
Thank you for watching! :-)
Hey Morten, dont configure Jumbo Frames on the Network port is you havent configured it on the rest of your network. for best results run iscsi on a seperate vlan or switch and only configure jumbo frames on that vlan or switch. you wil reduce your performance if you only set jumbo frames on the nic of the nas.
Hi N3m3515

hi morten, what 10gbit switch do you use? is it fibrechannel or copper?
Hi Hans Wurst

Thank you for watching! :-)
How do I go the other way? I have a empty datastore on my ESXI server that I want to backup my Synology NAS to
Give the space to a VM,, and have that make a copy..
Hvad med at lave videoer med Proxmox som du ville køre fremover.
HI DKAutomater
My channel is English, and to make sure as many as possible, can also enjoy the comments, they are also English.
Please keep to English.
Thank you for watching! :-)
My PlayHouse Hi Morten, could you create videos with Proxmox content instead?
Well this was meant to be shared storage between ESXi and Proxmox,, would be cool to move a server to the iSCSI storage,, and have Proxmox take over. it's propoly not going to work,, but cool.
PERFECT FILM I WANT TO TAKE A LANGUAGE OF ENGLISH .

Hi Stefan Rodic
Thank You very much! glad you liked the video :-)
Thank you for watching! :-)
@10:00 This is by far the most dangerous advice you have given on your channel. See what it says there in Red. You need a cluster-aware filesystem to connect this LUN to multiple servers at once. Most filesystems are not, Btrfs which you plan to use is not, NTFS, Ext4 etc are not. With those you WILL get massive data corruption when using the same LUN directly from more than one server. Must be one of the special ones for the multiple access to work: en.wikipedia.org/wiki/Clustered_file_system#Shared-disk_file_system
Hi rm
Thank You very much! But you might have missed that I installed VMware VMware VMFS at 19:45 and that is the file system the Hostes will be sharing.
