Dell R740 issues with XenServer 7.1/7.2 (Continued)

-
My previous post (https://allthingstechsmb.blogspot.com/2017/11/dell-r740-issues-with-xenserver-7172.html) indicated I was setting up 2 new R740s for our upgraded CAD/Revit VDI deployment.  We've had a few issues/learning experiences.  This is an extension of that posts with things I've found out since and new issues that have come up.  In addition, XenServer 7.3 solved one of our issues.

Storage Controller - H740p

This is a continuation of the issue with the H740p driver from the previous post.  This issue was resolved in XenServer 7.3, with the supported driver being included in the 7.3 install media.

Crash Dumps when booting in UEFI mode

While they have worked perfectly, I have been seeing crash dumps reported in XenCenter on every reboot when XenServer is installed in UEFI mode.  If you boot with BIOS and install, there are no Crash Dumps.

Per Rody Kossen (@R_Kossen), This will be fixed in XenServer 7.4, which is unofficially set to be released later this month (mid February 2018).

Per Bob Ball (@_BobBall_):


Network Information Disappearing

We've had issues with this for awhile, where the networking information disappears on the console of XenServer when added to a pool as secondary and then rebooted.  This shows over iDrac and on physical console access, but not in the console view on XenCenter.



Tobias has had some success by updating firmware, but we have not seen that same result:

Here's another discussion about this issue:
https://discussions.citrix.com/topic/377480-networking-missing-after-a-reboot-when-joined-to-a-pool/

Its interesting that this issue didn't show up initially after the 7.3 upgrade, but the network status went away again when changing timezone.

On that note, another post coming soon with time/timezone issues in 7.3 and a fix!

    The megaraid-sas driver available at https://support.citrix.com/article/CTX230552 seems to work fine for xenserver7.2.

Dell R740 issues with XenServer 7.1/7.2

My last post talked about our new Dell R740s.  Response to that post have pointed out that there are a few things worth following up with since people have been having some issues with this server/Intel Gold 61xx Processors. I had a few minor issues getting XenServer installed, but mostly around storage and networking. *I should note that my servers are showing crash dumps in XenCenter, but everything is working perfectly.  Waiting on my support case to have those SSRs analyzed (case originally started to ask about support for the H740p card in XS7.2).  I will post and update when I hear back tomorrow morning. Storage Controller - H740p We went with the H740p card which is not supported on XenServer 7.2 (although support tells me it may be soon) so we had to go to 7.1.1 (7.1 CU1) and install the driver at  https://support.citrix.com/article/CTX226401 .  If you had to load this to detect disks, make sure you install it AGAIN at the end during supplemental...

Autodesk in Virtual Environments and What is "Allowed"

-
Yesterday at Autodesk University 2018, I attended a session (SD227281) that was supposed to be about "Best Practices for Virtualizing Your Autodesk Software."  What ended up happening was some sort of confusing and illogical announcement about new Terms and Conditions around what is allowed and what is not allowed in terms of licensing models for virtualized environments.  To categorize this session as devolving into an infuriating train wreck would be an accurate description. After cooling down and doing some research yesterday I am even more confused, and some of what we heard was seemingly wrong. First I'll summarize what was "announced" and what was discussed in that session by the two senior Autodesk people (John Looper and Chris Kayser). Announced in the presentation: Autodesk will permit virtualization for: - Subscriptions with single-user access - Enterprise Business Agreements - Server-based components (Think Autodesk Licensing Server...

NVIDIA GRID on Pascal - A Card Comparision

I was all excited to post this, as I spent a decent amount of time on this subject leading up to ordering our new servers, and hadn't seen anyone else address it yet.  Then yesterday Jan Hendricks posted his thoughts on the subject which mirrored much of my findings ( https://jhmeier.com/2017/11/15/data-comparison-of-nvidia-grid-tesla-p4-and-p40/ ).  I guess that motivated me to finally finish my thoughts and get it posted as well! NVIDIA GRID 5.0 & Tesla Pascal Cards Photo Credit:  http://www.nvidia.com/object/accelerate-inference.html With NVIDIA GRID release 5.0 came support for Pascal GPUs.  While this brought many things (covered many other places), the most interesting part of this for me was that now ANY Tesla Pascal GPU works with NVIDIA GRID.  This opened us up to a wider array of options right away with 3 PCIe cards already generally available and an MXM option.  While NVIDIA pushed the P40 as the natural replacement for the M60, I w...
