Reply To: Synology NAS ISCSI Query “topic moved” Hi all, Does anyone have a Synology NAS and setup iSCSI? Totally new to ISCSI, never used it before. My HP microserver HD is getting a bit old now and…

Hi all,

So coming back ground to this and I’ve bought a HP Microserver Gen 10 plus along with a ILO enablement (so can access from my PC remotely via webpage), I saw its compatible on the vmware compatibility list for esxi version 7 so all looking good… I saw it had raid and completely forgot it was software raid (till after I clicked the buy button and started checking more) so its now on its way to me and I’m now loathed to spend approx. £200 on a raid card, of which reviews imply it is slow due to no cache.  I suspect its ok for day to day stuff but IF the raid failed, there are reports of it taking weeks to rebuild due to the slow writes etc so I’m not overly keen albeit I only have 2 x 2TB drives i mirror so not raid 5 etc.  An extra £200 on top of the price of the server is making this expensive so my options are either try ISCSI from synology nas OR I simply setup esxi on drive 1, setup VMs on drives 2 and 3 (no raid/protection) and hope the drives don’t fail and maybe once a month I shut down all my VMs and copy them onto my NAS as a backup – bit time consuming as they will likely take days to copy over.  I was a long process copying all my VMs off the other drives before putting back on the replacement drives in the gen 8.  I can only hope the NIC driver is better on the gen 10 :)

AS the thought of manually backup VMs isn’t something I want to be doing or worrying about loosing data, in order to make the server useable running esxi, I’m coming back to the idea of using my Synology nas as iscsi target and storing my VMs on that and then effectively esxi just loads the VMs from the nas box.

I had a quick look and looks very easy to setup the iSCSI target, however 2 issues:-

1. Which type of iSCSI is best for use on my RAID 5 Synology
2. When I create the ISCSI target, does it then wipe the volume or not as I only have 1 Volume on my NAS and it has all my data on it etc so I can’t afford to wipe it all out.

The guides say click through these steps and done but doesn’t say if it wipes the data or not on the existing volume.

So still trying to find out :)

Anyone know what type is best to use for iSCSI and also does it wipe existing volume when you set it up?

Thanks
