So you suggest setting the I/O Scheduler to NOOP, does this apply to all the different hypervisor's? We use KVM from Scale Computing here and I don't remember seeing this in any documentation for OES/SLES.

Hi Thys -
A couple of items I'd recommend...

On virtual linux systems, OES or SLES,  set the Global I/O scheduler to NOOP (no op). In a virtual environment you want the host vm to handle disk scheduling.
In yast, this is in System|Kernel Settings.

Also, you didn't mention it in your question, but I would recommend not running GW on OES, and if you do, don't run it on an NSS volume. I personal recommend Reiser on SLES11, and XFS on SLES 12. Others may have differing opinions.

HI All,
Ok we have a new vce/dell vxrail setup, vsan the whole thing .. so now my first time for GW and oes/edir for that matter .. when i try to create here are some new questions (not had this before on my small esxi hosts before ..what do i select?for now gw2012, will upgrade to gw2014 once on new solution
A few questions on VM creations... vCentre  vxrails ..... and this an All flash solution,,
For my normal OES/Linux boxes .. i know filr specify some these following questions but for my sles/oes/gw boxes what do i do?
1. Disks should i do "Independent" / "Independent -Persistent" or "Independent - Non-Persistent" .. sorry about this i just want to be sure .. heard horrible things about snaphosts and edir
2. Then also it talks about  "Sharing"?  ... "no=sharing" or "multi-writer" or " unspecified"  this is all new.. remember this is in a vSAN all flash setup for storage..if it matters....
3. "Virtual flash read Cache"? .. do i enable? and how big do i make this? 4Gb 8GB 10 or nothing?..
Kind Regards,
