Is VVOLs integration present in the 10799 release?

Did you guys ever figure this out? I have a similar issue. Testing the SAN Array locally pushes 2GBps + on both read and write but connecting from an ESXi 6.0u2 host over 10Gbe I can only get about 250MB-300MB read and write.

Any update on this?

Well, good news and bad news. Good news is a modified version of that command with a different claim rule for specific devices (don't use --vendor "starwind" if you have any HDD backed devices as this will cause them to stop responding) will claim the device as SSD after rebooting the host...

Take a look at my thread here: https://forums.starwindsoftware.com/viewtopic.php?f=5&t=4067 I had similar issues with SSD backed thick disks on an LSI controller in v8. I was not running raid and running in both IR and IT modes gave very poor performance on SSD. Taking the LSI controller out and...

Not using HA and the ESXi host(s) can connect to the LUNs just fine, they just do not see them as SSD and as such, neither do the VMs stored on the LUN.

Storage and Compute separated. The SW SAN consists of SSDs that are connected via LSI9211-8i in IT mode (No raid) and while the OS that SW is running on (Server 2012) recognizes the SSDs correctly, the ESXi host connecting to them via iSCSI does not. Even when the SSD are directly connected to the M...

I am noticing that the VMs do not recognize their virtual disks as SSD. In addition, ESXi (5.5 fully patched) does not recognize the iSCSI LUN as SSD either. Is this by design? I ask because I also notice the automatic maintenance task that runs by default on the Server 2012 R2 VMs appears to be def...

Hi Anatoly, I had run some tests with ATTO and HDTune and emailed the results to Max. Yesterday we got on a remote session and ran another battery of tests using ATTO and IOMeter. Max was going to check with the engineers in regard to the write performance we saw. I can loop you in on any additional...

Hi Max,

no L1 or L2 cache in v8 or v6 and the LSI controller has no onboard cache.

Hi Max, Sorry for the delay, I sent you an email today in regard to setting something up to have an engineer look at the system(s). Quick Update from some tests ran over the weekend: original v8-7774 box: Server 2012 FLAT devices good reads, slow writes LSFS devices good reads and writes LSFS defrag...

ESXi 5.5 VM SSD write speed to Thick Disk (imagefile) with no cache (L1 or L2) setup on v8-7774 (also occurred on 7509) running on Server 2012 is extremely poor. 50MBps best case. Reads are 400-500+MBps and I have tried on 4 different SSD types (V300, M500, 840EVO, 840PRO). I deleted the Thick Disks...
