HP Quadro K2000 in ML10v2


Recommended Posts

I'd like to start using vDGA on ESXi with my ML10v2.
The host is running ESXi 6.0 u3 HP Customized.

If successful/possible i'd like to be running a Windows 10 VM with a Quadro k2000
(in HCL list of vmware for vDGA)
The VM will have up to 12GB ram and 4vcores and the Quadro card in passthrough mode this vm is meant to broadcast live video to twitch/youtube/fblive using Xsplit.
live audio will be muxed in via virtual audio cable and local icecast server's stream.
It does not matter if the remote desktop is stuttering or choppy as long as the broadcasted material is acceptable. 

There will be a lot of video clips and overlays running, and i'll be run realtime 3D visualizations. the CPU and GPU would normally easily handle this workload.

A HP332T and NC112T will be replacing 3 out ot the 4ports of the NC364T as this card won't have enough bandwidth on 1x PCIe for 4x gbit connections.

(Considering the config of my ML10v2 (below in signature) and the fact i have a ml310e v2 front 80mm fan installed in server.) i'm just wondering:
1: can the ML10 v2 handle all it's PCIe lanes being saturated (pcie3.0: 8x for Quadro K2000, 8x for LSI/CISCO RAID9271CV-8i PCIe2.0: 1x for HP 332T and 1x for NC112T)?

2: will any of this config cause any bottleneck to any other hardware?
3: is this a feasible configuration? (The resources are there to be used, it will not push other VM's resources.)

I bought the card, and it works perfectly!
Took me a few days to figure out. (with some help) 
So this config works fine, but it's pushing it. 
The Xeon CPU provides 16 lanes of PCIe 3.0
Divided by the mainboard into 2x 8 lane pcie3.0
The card using 8 lanes, and the 9271CV using the other 8.
Or so i thought....
When I checked the OS' PCIe devices this popped up:

0000:00:01.0 Xeon E3-1200 v3/4th Gen Core Processor PCI Express x16 Controller
   0000:04:00.0 NVIDIA Corporation GK107GL [Quadro K2000]
   0000:04:00.1 NVIDIA Corporation GK107 HDMI Audio Controller
0000:00:01.1 Xeon E3-1200 v3/4th Gen Core Processor PCI Express x8 Controller
   0000:07:00.0 LSI / Symbios Logic MegaRAID SAS Fusion Controller

So does the CPU actually support 16x PCIe 2.0 + 8x PCIe3.0 lanes??
If so, Awesome...

I also figured the c222 chipset has 8x pcie2.0 1 lane interfaces.
Again PCIe check revealed something interesting: 

0000:00:1c.0 - Nothing 
0000:00:1c.1 - Unknown
0000:00:1c.2 - Unknown
0000:00:1c.3 - Unknown

0000:00:1c.4 - Hewlett-Packard Company 512MB Flash Backed Write Cache for B-Series Smart Array (wait what??*)
0000:00:1c.5 - Broadcom Corporation NetXtreme BCM5720 Gigabit Ethernet x2 (Onboard HP 332i)
0000:00:1c.6 - Broadcom Corporation NetXtreme BCM5720 Gigabit Ethernet x2 (Addon HP 332T) 
0000:00:1c.7 - Hewlett-Packard Company iLO4
                          Hewlett-Packard Company Integrated Lights Out Management Processor
                          Hewlett-Packard Company Integrated Lights Out Management Standard Slave Instrumentation and System Support

*weird enough, when I checked PCIe devices this device popped up. I have no idea if this is true or not, but funny find I'd say.


So the addon NC332t is connected through the chipset (c222) and so is the internal 332i
"driver" wise it should not make a blind bit of difference. it should operate like there's 2 BCM5720 chips with 2 connectors each. so even ESXi is not pissed off (too much) about it

i was dreading a PSOD, as i read about those happening sometimes... but none so far.

The K2000 is the only Compute/Video card supported as a official upgrade for this server and it's supported by ESXi (as vDGA interface directly passed through to one VM)
The card supports DX11 instructions, so instead of doing live streaming from the pc using loads of resources, the 4 core 8 thread xeon and the Quadro in passthrough to a windows 10 VM doing all the hard work.
getting the full 30-60 FPS on XSplit!

      Hi everyone, today I wanted to install esxi 6.7 to try out the various functions, my question is the following, I have a server where I have installed esxi in an SSD and I have two other 4 tb disks so 8 tb total.  I would like to make sure that when I create a virtual machine in this case I will install the various virtual machines in the SSD and use the two disks for data.  So how can I do this?  Thank you very much for those who can help me.

      Hello all,
      A few questions for those who use Type-1 Hypervisors on their Gen8 MicroServers...
      I am looking to try ESXi or ProxMox and have been reading a lot of the threads on here.
      Hopefully you guys can help with some harder to find answers I have been seeking.
      1) Which would be the better way to setup ProxMox:
           a) Hypervisor on Internal MicroSD, VMs installed on SSD in ODD Port, Data on 4x HDDs in bays.
           b) Hypervisor on Internal USB, VMs installed on SSD in ODD Port, Data on 4x HDDs in bays.
           c) Hypervisor and VMs both installed on same SSD (partitioned?) in ODD Port, Data on 4x HDDs in bays.
           d) Hypervisor on SSD using a USB-to-SATA cable on Internal USB, VMs installed on separate SSD in ODD Port, Data on 4x HDDs in bays.
      2) Would a 128GB SSD be a ‘waste‘ for installing a Hypervisor on? How much space is typically needed?
      3) How many VMs have you guys run on a Gen8 comfortably without it being sluggish?
      4) Everyone seems to be going RAID crazy these days. Is there any reason to use it if high-availability is not that necessary and a good backup plan is in place? What is wrong with separate disks (or singular Raid0s)?
      5) Does using Type-1 Hypervisors have any effect on the internal fans speed/noise? Is it possible to have 3-5 VMs running and still have the fan speed @~8% as it was when I was using 2 nested (Type-2) VMs?
      Sorry in advance if some of these questions are silly, common knowledge, or “depends on what you are doing in the VMs!” 😆
      Thanks in advance to all those that help!

      So, after several days of testing various different configurations, creating custom ESXi install ISOs and numerous reinstalls, I've managed to get ESXi 6.5U1 installed on my Microserver Gen8 and have working HP Smart Array P410 Health Status showing. For those that are struggling to do the same, firstly here's how. I used original VMWare ESXi 6.5U1 ISO, build 5969303 then made the following modifications:
      Remove driver "ntg3" - If I left this in, I had a weird network issue where Port 1 or 2 would repeatedly connect/drop every few seconds. This forces ESXi to use the working net-tg3 driver Remove driver "nhpsa" - this Smart Storage Array driver is what causes array health monitoring to not work. Remove to force ESXi to use working "hpsa" driver Add the Nov 2017 HPE vib bundles Remove hpe-smx-provider v650. - This version seems to cause the B120i or P410 to crash when querying health status Add hpe-smx-provider v600. (downloaded from HPE vibsdepot)
      Add scsi-hpvsa v5.5.0-88 bundle (downloaded from HPE drivers page)
      Add scsi-hpdsa v5.5.0.54 bundle (downloaded from HPE drivers page)
      I did the above by getting a basic/working ESXi/VCSA installation and then creating a custom ISO in VCSA AutoDeploy and exporting it. But the same can be achieved by installing VMWare's original ISO and modifying via the esxcli command.
      I have a SSD connected to the SATA port, onto which I am installing ESXi. The 4 front drive bays are connected to the P410.
      Configure the Microserver Gen8 B120i to use AHCI mode - the B120i is a fake raid card so only reports physical disks to ESXi. Leaving in RAID mode works but I got a false Health Alert on Disk Bay 5 Install my modified ESXi ISO to the SSD  
      With these modifications I have a working ESXi 6.5U1 on my Gen8 with fully functioning HPE tools and array health monitoring:

      I also tested disabling the vmw_ahci driver, which is why the AHCI controller shows it is using ahci in the above image.

      If I pull out a disk to test a raid failure, when the health status next updates I can see a raid health alert in the ESXi WebGUI:

      However I'm now stuck at the next stage - getting this storage health to pass through to VCSA. VCSA can successfully see all other health monitors (under System Sensors in ESXi) just not the storage, which is the most important.

      Does anyone know how I can get the storage health working in VCSA?

      I'm not sure I would call this a review, but I want to share some initial observations.
      Boot time is slow. I never had a Microserver before, so this might well be faster than the previous generation, but this is still pretty slow.
      It didn't come with any real instructions, the instructions just direct you to go to a url. The url is broken or not active yet. Nice one HPE.
      I loaded esxi 6.5 immediately. During the install process, it hung at 27% for a very long time. So long that I was sure it was locked up, so I went to download an iso of windows server to install instead, but when I finished downloading it I found out the esxi install actually did finish eventually.
      Installing a Windows Server 2016 Standard system as my first VM. For some reason it choked when I tried to start the VM with 5GB of RAM (out of the 7.5GB availible). Maybe the virtual dvd drive uses a lot of RAM? Set to 4GB, it starts fine. Still going through the install process at this point.

      I was looking at the specifications of the new Microserver Gen10 and I find them a bit disappointing, so I'm considering buying a ML30 Gen9 (872658-421). I have a few questions concerning this server.
      Is this server configured with 4LFF Hot Plug or 4LFF Non Hot Plug cage? Does I come with drive bay caddies? Which ones I have to buy if I use non HPE HDDs? What kind of HDD do you recommend? NAS HDDs or other?
      I want run some virtual machines on it and use this server as file server, webserver, database server. If I install ESXi 6.5 on it, can I create a RAID 1 for the datastore? Or do I need a RAID controller and which do you recommend? If it's not possible or too expensive, I probably go for Windows Server 2016 or Server 2016 Essentials and install VMware Workstation 12 Pro on it. Is this possible?
      Thanks in advance.
