ISCSI on Synology NAS for ESX4

Hi,

I would like to do some tests with my ESX4 server at home.
I have a Synology NAS on which I would like to make some LUN's.

There is already a lot of important data on that NAS (DS 210J) what I don't want to lose.
Can I just create extra LUNs ... and how do I do this?

J.

Rather than creating iSCSI LUN, I would recommend the use of NFS, in this way, you can just create a NFS Export (Share), and Mount that Share on the ESX server, in this way you do not need to create LUNs for use with ESX.

But if you want to create LUNs, yes you can do this.

What about performance between and possabilities for iscsi/nfs?

Performance using iSCSI and NFS will depend on many things, speed of disks in the NAS, RAID currently used in the NAS, networking between NAS and ESX server, if Jumbo Frames are enabled, this could help with iSCSI or NFS - however it may not.

If this is just for test purposes for a few test VMs for iSCSI and NFS - it may work okay for your purposes.

The DS 210J does not appear to be listed on the VMware HCL

Check the VMware HCL (Hardware Compatability Lists) here

http://www.vmware.com/resources/compatibility/search.php

These home in-expensive NAS, usually perform poorly for use with VMs, either using NFS or iSCSI, and often are used for backup or storage of ISOS.

If I create NFS, I get
Call "HostDatastoreSystem.CreateNasDatastore" for object "ha-datastoresystem" on ESX "192.168.1.12" failed when trying to connect from ESX.

It will perform slow but should work. I would like to test before buying a more performant one.
The manual of 210J mentions vmware and scsi targets so that should work, maybe nfs not.
So I can create a iscsi target without losing data on nas and point my ESX to it

that particular error message can occur when access is not setup correctly, or mount points are incorrect.

do you have a vmkernel interface configured?

yes, if you follow the instructions for creating a LUN.

I created a NFS share and pointed VMware storage (NFS) to this storage.
Something like 192.168.x.x then NFS share /volume1/vm

Am I missing something?

Oh, so I should create this first. I'll check.
