Thanks! The main "pain" is that when having multiple ESXi-hosts accessing multiple LUNs/datastores, no hosts can use the LUN when marking as flash in the vSphere Web Client. So I have migrated all VMs to other datastores, (formatted as VMFS6) and marked as flash on one and one hosts. This ...

Is it possible to force a device to be identified as a SSD? It is very annoying that all my devices in vSphere is identified as a regular HDD. This is because the Megaraid-controller is not reporting as SSD to the OS Starwind is running on.

Hello! After installing Windows Server 2016 (from scratch), performance was much better. It was a little bit unstable (as in varied between 400-800MB/s in VM), but much better. I'm looking forward to installing a few 40gig cards in my most powerful VMware hosts, and run some benchmarks with end-to-e...

I have been a couple of weeks on Gran Canaria, but I hope to test in a few days.
Will Starwind run fine on Windows Server 2016 ?

The problem was there from the start when installing/upgrading to the new 40gig card. I did try to swap the cards with the same result. I think I will reinstall Windows, just to rule out some driver/settings issues. Will try the driver you recommend. Thanks! I know this is not a Starwind issue, but ...

I'm currently on driver version 5.22.12447.0.
ESXi 6.0 build 4192238

We are having some performance issues in our environment. That is, write performance for one path on one of our SANs. We have a dualport 40GbE Mellanox Connectx-3 for sync + ISCSI and a dualport 10GbE Emulex for ISCSI on each HA-pair. This is a VMWare environment, and all hosts have Emulex dualport ...

So for Free version, remote ISCSI is disabled, even if installed on dedicated physical servers?

If running Starwind Free on two dedicated physical servers (no Hyper-V etc), are there any limitation on HA ISCSI targets (shared storage for ESXi-servers)

lohelle, the most important feature of VAAI, is all of it.

Thanks

Actually, I don't agree here, as the other features mostly help on performance, but missing VAAI UNMAP/DELETE prevents the thin-provisioned volume from shrinking as it should/could.

Can you please confirm that this is a known issue? (VAAI + LSFS with deduplication). The zeroing is the most important feature for us, but accellerated copy yould also be great.
As mentioned, this works on thick devices.

VAAI zero works on non-dedupe thick. I have not tested other combinations yet.

I have done some testing using latest Starwind and ESXi releases. Tests: Created LSFS datastore (dedupe) of 100GB and added to ESXi host. I cloned 3 VMs from a template. Used space did not grow much/at all for the 2 latest clones. Copied 10GB of files to the first VM. Allocated physical space increa...

If 9k packets (9000 BYTES), what sould be something like 150k packets/s on a 10gig-link.
64 byte packets would max out at 20Mpps for a single 10gig link.
These are single direction numbers, so double the numbers for full dupex.

Well..
If one of the hosts fail (or down for maintenance), I would feel a bit worried for the other node..?
What if the RAID-controller failed on node1, and you had to wait for days for a replacement? Would you feel safe in the meantime?
