Does anyone know if you can buy a PCIe 3.0 x16 low profile card that supports FOUR M2 NVMe drives? I found this Supermicro card which supports TWO drives but I am looking for a card that supports FOUR drives...

Yeah it does, thanks. I've enabled VBS in all my VMs so will be interesting to see how this goes. Can VBS be enabled/installed in Core edition of Windows 2016/2019?

I've just upgraded to vSphere 6.7 Update 1 and one of the first things I wanted to start experimenting with is Virtualization Based Security (VBS) in my VMs. I have a Win2016 and Win2019 VM I have installed with hardware version 14 and VMware Tools 10338. Windows is patched with October 2018's...

Oh blast, that's really annoying! So I have no way of working out how my CPU with operate with Turbo Boost?

I've been reading the vSphere 6.5 Host Resources Deep Dive by Frank Denneman and have just finished reading the chapter on power management. In the chapter he talks about Intel Turbo Boost and Turbo Bins. The Turbo rates look like this for an E5-2450: 5/5/6/6/7/7/8/8 I currently have the...

It would have been defaults as I didn't change a thing after creating the pool (ie: all defaults). Whats the thoughts on using lz4 compression with iscsi and VMs? Good? Bad? Use it? Don't use it?

I have deleted the zpools until the new disks arrive but how do I check if iscsi is using sync=always? I'll check this when I create the new pools next week when I have all the drives.

Yeah I think I am going to install the Pro's in the hosts themselves rather than in FreeNAS. I considered using all the SM863 drives in a single pool but I would like to have two pools. One for performance (where most VMs will run) and one to maximise space (for templates etc). I've got my 4...

Now that my storage seems to be stable for now I would like to have a rethink about how I configure the ZFS volumes on my FreeNAS server. Next week some new SSDs will arrive so I'll have the following: 4 x Samsung SM863 480GB SSDs 4 x Samsung SM863 960GB SSDs 2 x Samsung Pro 840/850 512GB...

So touch wood and all that I haven't had any disconnects since my last post so I'm assuming all my pain was due to jumbo frames....

Heh, watch this space! Thanks again for all the help and input.

What I should have asked in my previous post is: If I have the disconnect happen again, what NICs should I consider for storage traffic if continuing to use direct connect? PS: Thanks for Juniper mention!

Yip, learned that they hard way! When I still had jumbo frame enabled the disconnects funnily enough didn't happen at all while running some bench marking tests. It didn't happen when I manually ran a Veeam full backup job. I wasn't looking in the logs at that stage though but after the crash I...

Well thanks for typing up such a great reply! This is really interesting because I had an issue with iSCSI performance when I tried to use my Cisco SG300-28 switch for storage traffic. The performance was terrible (there's a post on this forum about it). That's why I direct connected all my...

Glad everyone's enjoying my pain ;-) I'm not ready to throw in the towel just yet and move over to NFS haha This entire troubleshooting exercise has taught me loads and I'm just wondering if all the issues I had with Starwinds Virtual SAN was due to the jumbo frames too. Will be interesting...
