[OmniOS-discuss] Best infrastructure for VSphere/Hyper-V

Thu Apr 2 19:24:59 UTC 2015

I´m running maybe 7 active VMs on two servers across two different luns/pools (basically have a "Fast" storage Pool and a "Slower" storage Pool).

I remember that i had also a problem on IBM Server... 
See http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1030265
That helps me...
How many VMs did you had on every lun? 
Big lungs make sometimes trouble on vmware.

You mentioned Queue depth. I will have to check into recommended settings for HyperV...

My Storage Pool is about 32TB raw (10TB used), and I have 6 luns. I also have a 6TB pool that is 2 luns feeding my 3 system hyper-v cluster. 

Situations that trigger dopout behavior include: snapshot initiation on the hypervisor, checkpoint deletion (with accompanying vhdx merge). I´m using Dell R720s with QLE2562 cards. 

I´ve also had this problem on an IBM server SR2625ULXLR which was an intel 5520 chipset. We discussed this a bit back, but both these systems have risers, and we surmised it could be a riser issue, but I don´t know if I buy it.

So FC Switch is a dual (full mesh) HP8-20Q which is a Qlogic OEM. 

How do I turn of sr-iov and pci-express speed? Is this a Bios or Omnios setting? I posted errors a couple times.  
(you responded these could be bios)

I get weird "Drop outs" in certain IO situations. I get no notice of the drop out, just a notice when it comes back up.

Which server system do you use for storage? HP, DELL, Supermicro? 
Turn off sr-iov thats make many problems and try to turn off auto detection für pci-express speed. And don´t use any PCI-Express slots for graphic cards!

Hmmm. Was hoping for an 8GB variant (I´m on QL2562), might have to go down to this to see how well it works.

Thanks,

Of course... 
We use Emulex LPe11002 Dual Port 4Gb PCIe Fibre
With latest firmware. Works great!!!
All VMServer use RoundRoubin as pathselection.
For FC Switch we use 2 x Brocade 5000. 
Low cost, good speed an stable ^^

Hi,
we had very good experience with omnios and fibrechannel. 
We tried it with infiniband and SRP but no look. Because the Mellanox driver were only community based. 
But after we changed all back to FibreChannel ist works great. 
We use only EmulexCards, because there were listed by VMware in the HCL for ESXi 5.5

We had 10 VMHosts, 3 Storageserver each witch 1 dual port FC Card.
They host 124 VMs, 10 Terminalserver, 5 SQL-Server, and 8 ExchangeServer. 
No Probs thins were changed back to FC!

So i can say, use HCL listed Cards for VMWare!

Bye
Thomas

Is it limited to NFS on VSphere, or is there some way I can get this working with Hyper-V (which would be vastly preferable due to licensing advantages for me)?

Hyper-V uses SMB3.0, right?  Like iSCSI, illumos community member (and storage vendor) Nexenta has done nontrivial amounts of work here.  It's "simply" a matter of upstreaming it.
