I'm glad you found a solution. I wanted to confirm that you were delivered a vSAN ready node that included hardware not on the vSAN HCL. Is that correct? Thank you, Zach.
That is correct. Though I don't know what defines VSAN ready node to dell. For the 13G servers I only see a Dell R630. I do know the servers were spec'd for VSAN 5.5/ESXi 5.5. U2
When I updated the firmware, I noticed we had Lite-On drives. I plugged them into the HCL and they were not on the list for ESXi 5.5 U2 with hybrid disks. They only showed up for ESXi 6.0 All Flash arrays.
I confronted them about it, and i think now they will do a deeper check into all components. While the update did fix the issue. I pressed Dell to replace the drives with SSD's on the HCL.
We replaced them with Dell Branded intel 3700's.
The issue was a serious firmware flaw with the garbage collection process/removal ..Under heavy I/O eventually they stop responding..
This was firmware version LPCF11XC. Dell is shipping Dell 730/730xd with these drives or intel 3610.(also not on the list for ESXi 5.5 U2) Updating to LPCF11XU in the Dell Nautilus SSD drive update corrected problem, but there was no way were gonna keep these. The specs dont even compare to the intel 3700 (drives we got with 12G servers)
So in the end, though Dell claim there was a documented issue with firmware version 25.2.2.0037 for the H730P. The SSD was the factor here.
We worked with Dell and assumed based on the specs we gave the VMware based reps would put together a node based on this list. Our past order when VSAN was first GA was spec'd from this list.. R720/H710 controller..etc
When we ordered, the 13G servers were out and you could no longer purchase R720's. So they put together certified hardware for 13G servers. I can tell by that list it was not a VSAN ready node then..
There are no 13G configs on that list for ESXi 5.5 only 6.
We got a R730..not a R730xd... where the gamble with Dell on the VSAN node list/or otherwise is Solid State Drive SAS Mix Use MLC 12Gbps 2.5in Hot-plug Drive
Dell substitutes in Dell branded SSD's of various manufacturers.. some of which are not on the HCL...a big oversight if you ask me.
Hi Everyone, if you're running the dell provided SSD's, LiteOn, run the Nautilus utility and flash them ASAP.
I just ran it on Monday, and performance is now acceptable, and everything appears to be stable. STOKED!
Anyone have some performance metrics with Crystalmark that you can share based on our similar configurations?
I'm seeing 330/240MS/s on 2GB sequential.
Hey Max tried to reach out to you when I found out about it almost 2 weeks ago.. Glad you resolved, We did not keep those liteon drives..as we have ESXi 5.5. They were certified for ESXi 6.0 all flash.
Hope your troubles are over.
What's your storage policy for that VM's bench-marked disk? What stripe-width?
