HPE Moonshot have been around for some time now, and I have been very lucky working together with HPE and testing their server cartridges that are compatible with Citrix solutions. Last year, at HPE Discover in London, I wrote an article about how Citrix internally are using HPE moonshot and which server cartridges were available at that time and how financial customers are benefiting from these solutions.
Earlier this year I have seen several customers having issues with AutoCAD in Citrix not defaulting to the primary display adapter, so the GPU wouldn be fully functioning and Autodesk AutoCAD 2016/2017 would turn off hardware acceleration. This issue have been seen on NVIDIA Gpus such as GRID, NVIDIA also have a official KB on this http://nvidia.custhelp.com/app/answers/detail/a_id/4092/ and issue is also seen with INTEL gpu such as Iris Pro Graphics more specific on solutions with HPE Moonshot 710p and 710x.
Issue is identified on both Citrix XenApp 7.x (Windows Server OSs) and Citrix XenDesktop 7.x (Workstation OSs)
“The primary display adapter is not shown as the default in a Citrix environment.”
I am happy to share that Autodesk have finally fixed this “bug” with Citrix and now the GPUs will work correctly with Autodesk AutoCAD 2016 and Autodesk AutoCAD 2017 when you apply below hot fix for the product you have.

Its time to update your NVIDIA GRID K1, K2, M6, M60 environment.
NVIDIA have released new drivers that supports Windows 10 + fix several bugs.
If you want to test Server 2016 then the new Windows 10 drivers works, I have just tried and they work but they are not “certified” so test this with your own risk, please. Always test this in a test environment and this is not for production environments, unless you want to be early innovators 😉
#HINT – Windows 10 is not supported on Citrix XenServer 6.2 only on Citrix XenServer 6.5.
## HINT – Linux drivers are only available with Tesla M6, M60.
Whats new in vGPU 352.83-354.80
NVIDIA have released a new version of vGPU 352.83-354.80 for NVIDIA GRID 1.0 (K1, K2) GRID 2.0 Tesla M6 and Tesla M60 platform.
NVIDIA GRID Virtual GPU Manager versions 352.83 for Citrix XenServer 6.2 SP1 with hotfixes XS62ESP1009 and XS62ESP1011
NVIDIA GRID Virtual GPU Manager version 352.83 for VMware vSphere 6.0 Hypervisor (ESXi)
NVIDIA Windows drivers for vGPU version 354.80
NVIDIA Linux drivers for vGPU version 352.83.
Important:
The GRID vGPU Manager and Windows guest VM drivers must be installed together. Older VM drivers will not function correctly with this release of GRID vGPU Manager. Similarly, older GRID vGPU Managers will not function correctly with this release of Windows guest drivers
Update existing vGPU GRID Manager (Hypervisor)
GRID vGPU Manager 352.83 upgrade for Citrix XenServer 6.2
If you have a NVIDIA GRID K1, K2 vGPU GRID manager installed in Citrix XenServer. Upgrade with below methodology:
Methodology 1 – the manual way “No GUI”
Upgrading an existing installation of the NVIDIA driver on Citrix XenServer 6.2, use the rpm -U command to upgrade:
If you have NVIDIA GRID K1 / K2
[root@localhost ~]# rpm -Uv NVIDIA-vGPU-kepler-xenserver-6.2-352.83.i386.rpm
Preparing packages for installation...
If you have NVIDIA GRID TESLA M6 / M60
[root@localhost ~]# rpm -Uv NVIDIA-vGPU-xenserver-6.2-352.83.i386.rpm
Preparing packages for installation...
The recommendation from NVIDIA is to shutdown all VMs using a GPU. The machine does continue to work during the update, but since you need to reboot the XenServer itself, it’s better to gracefully shutdown the VMs. So after your VMs have been shutdown and you upgraded the NVIDIA driver, you can reboot your host.
Verify that the NVIDIA kernel driver can successfully communicate with the GRID physical GPUs in your system by running the nvidia-smi command, which should produce a listing of the GPUs in your platform:
Check driver version is 352.83, if it is then your host is ready for GPU awesomeness and make your VM rock.
GRID vGPU Manager 352.83 for Citrix XenServer 6.5
If you have a NVIDIA GRID K1, K2, M6, M60 vGPU GRID manager installed in Citrix XenServer. Upgrade with one of below methodology:
Methodology 1 – the manual way “No GUI”
Upgrading an existing installation of the NVIDIA driver on Citrix XenServer 6.5, use the rpm -U command to upgrade:
If you have NVIDIA GRID K1 / K2
[root@localhost ~]# rpm -Uv NVIDIA-vGPU-kepler-xenserver-6.5-352.83.x86_64.rpm
Preparing packages for installation...
If you have NVIDIA GRID TESLA M6 / M60
[root@localhost ~]# rpm -Uv NVIDIA-vGPU-xenserver-6.5-352.83.x86_64.rpm
Preparing packages for installation...
The recommendation from NVIDIA is to shutdown all VMs using a GPU. The machine does continue to work during the update, but since you need to reboot the XenServer itself, it’s better to gracefully shutdown the VMs. So after your VMs have been shutdown and you upgraded the NVIDIA driver, you can reboot your host.

Click Finish on the Install Update section
After the XenServer platform has rebooted, verify that the GRID package installed and loaded correctly by checking for the NVIDIA kernel driver in the list of kernel loaded modules.
Validate from putty or XenCenter CLI
run lsmod | grep nvidia
Verify that the NVIDIA kernel driver can successfully communicate with the GRID physical GPUs in your system by running the nvidia-smi command, which should produce a listing of the GPUs in your platform:
Check driver version is 352.83, if it is then your host is ready for GPU awesomeness and make your VM rock.
GRID vGPU Manager 352.83 for VMware vSphere 6.x
To update the NVIDIA GPU VIB, you must uninstall the currently installed VIB and install the new VIB.
To uninstall the currently installed VIB:
Stop all virtual machines using 3D acceleration.
Place the ESXi host into Maintenance mode.
Open a command prompt on the ESXi host.
Stop the xorg service by running the command:/etc/init.d/xorg stop
Remove the NVIDIA VMkernel driver by running the command:vmkload_mod -u nvidia
Identify the NVIDIA VIB name by running this command:esxcli software vib list | grep NVIDIA
Remove the VIB by running the command:esxcli software vib remove -n nameofNVIDIAVIBYou can now install a new NVIDIA GPU VIB
Use the esxcli command to install the vGPU Manager package:
If you have NVIDIA GRID K1 / K2 select following file:
After the ESXi host has rebooted, verify that the GRID package installed and loaded correctly by checking for the NVIDIA kernel driver in the list of kernel loaded modules.
Verify that the NVIDIA kernel driver can successfully communicate with the GRID physical GPUs in your system by running the nvidia-smi command, which should produce a listing of the GPUs in your platform:
Check driver version is 352.83, if it is then your host is ready for GPU awesomeness and make your VM rock.
Update existing vGPU Driver (Virtual Machine)
When the hypervisor vGPU GRID manager is updated next is updating the Virtual Machines vGPU.
Update your Golden Images and reprovisioning the new virtual machines with updated vGPU drivers, if you have stateless machines update vGPU drivers on each.
#HINT – Express upgrade of drivers is the recommended option according to the setup. If you use the “Custom” option, you will have the option to do a “clean” installation. The downside of the “clean installation” is that it will remove all profiles and custom settings. The pro of using the clean installation option is that it will reinstall the complete driver, meaning that there will be no old driver files left on the system. I most of the time recommends using a “Clean” installation to keep it vanilla 🙂

Last year I was invited by HPE to go to their EMEA event HPE Discover in London, which took place the first week of December. I was invited there as part of their Hewlett Packard Enterprise Independent Influencer Program, and I was super proud of being part of this well organized program, which Kristen Reyes manages. HUGE kudos to Kristen Reyes and her team for putting together one of the most organized events I have ever attended as a blogger. Last time I attended HPE Discover was some years ago at their big US HPE Discover which took place at Las Vegas. I remember it was HUGE with lots of people – an epic experience that my previously employer, Arrow ECS managed the trip for. I had pretty high expectations going to the HPE Discover and I knew it was going to be good, but not as good as it REALLY was.
HPE Independent Influencer Program:
I am proud of being part of this program – let me tell you which profiles are part of the program including myself.
The team behind HPE took care of us from the time I flew all the way from Denmark to London. They made sure we got the right hotel and then once at the venue, we got a special VIP room where we got introduce each other. Team had a plan for what happend exclusively for the group. This reminds me of the Citrix CTP program I am humble to be part of where we also meet 2 times a year and are taken especially care of.
I highly recommend you follow above persons, as they are awesome people. This is the first time I have been with such a wide range of technology bloggers in my life and it was a huge difference – so thank you to HPE for daring to put so many different profiles together.
Let’s talk about HPE Discover in London 2015
There was 13.000 attendees. YES! That is INSANE and it felt like being in United States but I was in London. London can also have huge venues and they succeeded with cherry top on the beautiful cake. Yes HPE pulled it off! Please other big vendors – start making EMEA events because London is a perfect spot for this! Citrix, VMware, Microsoft… EMEA salutes you..
I was in for a surprise the first day of the keynote when Meg Whitman kicked off HPE Discover, and Satya Nadella Microsoft CEO talked even thought it was via a conf call (but still pretty cool) and Microsoft showed the flag. I would have loved if Satya could have come in person since that would have been my first time seeing Mr. Nadella in person.
After a great keynotes learning about where HPE is taking the company, it was time to walk around the expo to see what innovative technologies were hidden and what others I was allowed to blog about.
Next gen consumer products for engineers & designers
This device is so beautiful the brand new HP Envy 34, its the widest screen I have ever seen on a professional computer and its powered by Intel HD530 GPU and NVIDIA GTX 960A GPU. The speakers are B&O (Danish design brand).
Price for this device is approx 1700 USD – that’s pretty cheap for an All-in-one machine.
Another beautiful Augmented Reality device I tried was the HP Sprout. This device makes it possible to quickly edit 3D models in real time by taking objects from reality and scanning them directly in to the device. Then you can manipulate with the object and then print it out on a 3Dprinter. This process increases the speed of making a design. Right now, the device is only available for consumers but we might see that change soon for enterprises since the unit was displayed at the HPE Discover 🙂 – so watch out for this space. I also saw AMD had setup several Oculus Rift DK2 units running some great demos. Great to see that VR was at HPE Discover.
Deep Learning & The Machine
I meet many of the brains behind the Deep Learning “things” HPE are doing, and its VERY impressive where they are, and how HPE differs to their competitors. I can’t talk much about it now – and will leave it up to how things are evolving later this year – and then blog more about it when the information is available to the public. But if you are fascinated by the future and AI / Deep learning you should look at what HPE is doing with the concept, “The Machine”. If you look at what they are trying to accomplish and put the puzzle together yourself, you might see for yourself how HPE will make a difference in how next generation datacenters will be built – that’s a fact.
Citrix Octoblu & HPE – The Cube
(The ultimate iOT automated conference room)
HPE Smart Digital Collaboration Space (1107), a.k.a. “The Cube.” . That was the name of this cool concept.
This was mind-blowing – and one of the most innovative things I saw at HPE Discover with IoT using Citrix Octoblu.
HPE, together with Aruba and Octoblu have teamed together to create a beautiful workflow that automates a conference room with iOT.
All visitors could try this at the event. HPE allowed 3-4 people to enter the cube as a group. We were asked our name and then were given an iPhone to bring into “The Cube”. The system then welcomed use by name and the room went from “green” to “red” (which was Philips Hue that did this), so the people outside could clearly see that the room was occupied and a meeting was taking place. An HP tablet on the door outside also showed the room was occupied and listed the attendees by name. Inside, the HP surface PCs connected to Skype for Business, Samsung TV started and a business session went live. At the end, “The Cube” took a selfie and put on twitter and sent the photo to our emails and after we left the room. Upon exiting, it reset all the workflows and the room was lit green again – ready for next group. Amazing 🙂
Below is the workflow that was created in Octoblu
Try out octoblu here if you havent tried it yet. Its still beta and “FREE” https://octoblu.com/
It was great to see all the new NVIDIA GRID 2.0 solutions. Two gentlemen proudly showed the HPE ProLiant WS460C Gen9 that now supports NVIDIA Tesla M60 and NVIDIA Tesla M6. This means higher density and more performance. So great to see that HPE is a pioneer, offering the entire solution from NVIDIA. There is soon NVIDIA GTC – and I expect we will see some data on customers running on HPE solution with M60/M6 and we get some data on how many users can run on these new offerings. It’s actually my first time seeing on-hands the M6 GPU from NVIDIA and it looks beautiful and green. These GPUs are made for low end GPU workloads all the way up to high end GPU workloads. The performance of the M60 is 2x the performance compared to K2 (GRID 1.0)
Please keep in mind that NVIDIA has changed GRID 2.0 so when you buy the GPUs, you also have to buy a “software” license.
Your NPN (NVIDIA preferred partner) should be able to help you with providing you the correct information. This license is required both for Pass-through and vGPU of the M60 and M6.
Moonshot and beyond
HPE Moonshot has been a subject I have been following for a while now. It all started when one of my great friends (and fellow CTP) Dane Young talked about HP Moonshot and why it differs to the market. HPE liked Young’s view – and his face is now on the wall at the Houston research facility. So if you are a client or a partner, you might know Dane Young – or you will if you are in Houston to see what HPE is doing with HPE Moonshot.
Citrix had a booth at the HPE Discover and they showed how Citrix is working and offered on a HPE Moonshot stack.
The HPE Moonshot team had several sessions talking about the next generation “trader workstation” which opens my eyes on how users use a computer. Traders are actually some of the most “difficult” users to satisfy – and they have a very short lifetime as an employee because its so hard what they do is so stressful. The amount of monitors and amount of data they look at is shocking and the high availability for this is nothing like you have never seen before. If these people cant work, the moneyflow stops moving – something you don’t want in the financial world. Designers are one thing, but I would definitely call traders the most difficult users. So what´s so amazing about the HPE Moonshot offering? HPE has a new catridge called the M710P, which was released in the Summer 2015. It has a high amount of CPU/GPU (or as others call it APU which is a CPU/GPU processor in 1 unit). Lots of memory and high speed disks. This is all build in a super small server which we call a cartridge. This cartridge can be put in a system and an OS can be installed and now you can have many users connecting to the catridge and using multiple sessions from Microsoft Remote Desktop Services combine this with Citrix super power “XenApp” and you now have an amazing flagship for having high amount of users with low cost. Nothing is virtualized and everything is running on bare metal. The beauty about the moonshot is that in 1 chassis you can put in 45 catridges of the M710P.
Moonshot cartridge building blocks for Citrix workloads
These are the offering that HPE have with Moonshot and Citrix and you can build amazing workloads. Personally, I would look at the M710p because I think this is the cartridge that is mature for the workload. I normally design Citrix solutions with.. wait are you talking about GPU? Yes I am..
If you remember some time ago, Brian Madden, said “Imagine if you could put 20.000 users in a single rack? Let’s see what has happended since then. Things have evolved – and with the new cartridge M710p, its much more powerful than the first cartridges that were built for Citrix
Citrix is using Moonshot internally
At HPE Discover, Citrix had a session with Bob Thompson from Citrix and together with the HPE Moonshot team EMEA telling how Citrix is using HPE Moonshot.
I had never heard about Citrix is using it at this scale – and big surprise their demo cloud is also running on Moonshot.
Insights what Citrix IT are doing with HPE Moonshot
“Citrix on Citrix” – team responsible for deploying Citrix products internally
Upgrading to latest version of XenApp
Seamless app access from Windows 10 devices
Superior user experience
Improved security (e.g. both FIPS Compliant and Common Criteria certified)
Migrating to Moonshot (m710) for XenApp from HP Blades
Designed and optimized for XenApp
Less: power consumption, space and cabling
8,500 sessions, across the globe in (4) data centers
“WOW so why arent more people using Moonshot, if this is so good and Citrix is doing this, it is mature”.
M710P & Citrix – Next gen trader workstation
I am very impressed about this new machine and HPE is having HUGE success with this machine for the financial buisness. In fact, some of the biggest banks in the world are running on this. Surprised ? IT’S TRUE
Let’s look at the details of what it is.
Here is a typical trader running with 4 monitors connecting to 1 catridge M710p and only 47% of the GPU is utilized. AMAZING!
M710P catridge – hardware specifications

450 CPUs
1180 Cores (3600 with HyperThreading)
54TB – 430TB iSSD Storage
18,000 XenApp users (@40 users per server)
I hope the above gives you a pretty good idea on where Moonshot is going – and this is just for Citrix. HPE Moonshot is much more though -it’s a huge eco system build for enterprises and cloud providers, so check it out https://www.hpe.com/us/en/servers/moonshot.html
More informations about HPE Moonshot M710p – The Trader Workstation:
HPE Discover 2015 blew my mind – and it looks like we are going to have an amazing year in 2016.
I would like to say thank you to Kristen Reyes from HPE for making this happen. Each time I didn’t know what to do, she and her team took great care of me and made sure I meet the correct people at HPE – and there was always “open doors” (which isn’t always the case when techies sees a guy with a “blogger” sign around his neck).
Citrix have release Tech Preview 2 of Citrix XenServer (next release). Great news for customers, partners, cloud providers using Citrix XenServer. The XenServer team have improved again the Dom0 and made the hypervisor even faster, this will be interesting to see if XenServer will be faster than the competitor VMware vSphere. Intel GPU virtualisation is now part of the hypervisor and again Citrix is leading the GPU virtualisation space as nr 1 compared to Microsoft and VMware. If you have a server with Intel Iris Pro graphics on Broadwell and Haswell processors equipped with the C226 chipset you can now virtualise the GPU to a VDI/XenApp. Software thin provisioning for SAN is now available in this release so XenServer better can utilise storage and not consume lots of space with “block based” as previously releases, a lot of customers is going to love this feature + a lot of new awesome features…
Important information before testing this release.
Known Issues and Advisories in this Tech Preview
NVIDIA vGPU cannot be used in conjunction with this Tech Preview. GPU Pass Through is supported. So if you have NVIDIA GRID vGPU running in your environment and you upgrade with this technical preview, I advise you not to do this.
Why Citrix XenServer Tech Preview 2
As a core component of the Citrix portfolio of products, Citrix continually strive to ensure that XenServer remains the best possible platform for hosting Citrix solutions, and for fulfilling the needs of server virtualization and Cloud customers.
This Technical Preview 2 offers enhanced features and functionality for application, desktop and server virtualization use cases. In addition to improved support for large-scale Microsoft Active Directory infrastructures and enhancements to XenServer control domain responsiveness, the Tech Preview includes:
Improved heterogeneous pool support
Support for software-boot-from-iSCSI for Cisco UCS
Support for hardware-accelerated graphics processing
Enhanced block and file based storage features
Increased scalability
Terms of access and use
The Tech Preview 2 is only available to existing customers, and requires a Tech Preview license key. The license key is available from this page and needs to be installed on a Citrix License Server.
This preview is intended only for existing Citrix XenServer, XenApp or XenDesktop customers.
The previewed features and enhancements are being considered for inclusion in future versions of XenServer. They have not yet been fully integrated or productized, and there may be debugging code in place.
This is not a fully featured release, is not intended for use in any environment other than test or development, and should not be used for production workloads. Citrix does not guarantee that any preview features or functionality described here or within the downloadable product will be made available in a future releases.
Enables XenServer to boot from SAN via iSCSI, complimenting existing FC boot capabilities.
XenServer can be installed to, booted from, and run from a LUN provided by an iSCSI target, which is specified in the iSCSI Boot Firmware Table (iBFT).
Helps reduce infrastructure costs by removing the need for expensive Fibre Channel HBAs.
To use this feature, see Enabling Software-boot-from-iSCSI later in this document.
Intel GVT-g virtual GPU for Windows
We continue to collaborate with our partners, in driving innovation in the virtualized-graphics domain. Within this Tech Preview, we showcase Intel’s virtual GPU; a graphics acceleration solution that requires no additional hardware:
Uses the Intel Iris Pro functionality on Broadwell and Haswell processors equipped with the C226 chipset
Utilizes a standard Intel GPU driver, installed within the VM
Experience the benefit; simply RDP into a Windows 10 or a Windows 8.1 VM and run a graphically demanding application
Software Thin Provisioning for SAN
With thin provisioning, a small amount of space is allocated initially to VDIs, which grows on demand, leading to far more efficient utilization of storage space. This will enable a significant reduction in the cost of ownership for the storage component of a SAN-based (LVMoiSCSI and LVMoHBA) XenServer environment.
This contrasts with previous versions of XenServer which only supported fully provisioned storage for block storage.
Support for SMB Storage
XenServer is now able to use SMB1 storage as an SR type.
1 SMB is sometimes referred to as CIFS.
2 Press F10 when the installer boots to enable boot-from-SAN and to configure Open-FCoE settings.
Customers with existing SMB storage (ubiquitous in many Microsoft environments) can now utilize SMB as their XenServer SR, and therefore may need no additional storage for their XenServer environment, enabling significant potential cost savings.
Support for Offline Storage Migration
Enables storage migrations to be undertaken with the VM in a stopped or suspended state. Currently customers are only able to migrate the storage of a VM, if the VM is actually running.
Support for NFSv4
Adds support for the current version of the NFS standard and complements the existing NFSv3 support, delivering additional performance improvements.
Support for Open-FCoE
Supports software FCoE, which can be configured easily using the XenServer installation program. Software-based FCoE delivers the same benefits as hardware-based FCoE. It alleviates the need for using expensive HBAs, but does so using less-expensive network adapters, in an entirely software-defined manner.
This Tech Preview also supports boot-from-SAN from Open-FCoE and includes an updated installer2 to assist with the configuration of Open-FCoE.
Improved Performance & Scale
We continue to deliver ever greater performance and scale, enabling customers to realize economies of scale and processing efficiencies.
Increased Host Memory
Support for up to 5 TB of system memory, accommodating even the largest workloads.
Support for up to 1.5 TB of Memory per VM
For memory-hungry VMs3, such as those running databases, we now support up to 1.5 TB of memory.
Improved Dom0 Responsiveness
The responsiveness of Dom0 has been significantly improved when subjected to heavy VM load.
Support for 256 CPUs
Support for up to 256 physical CPUs, accommodating even the most powerful servers.
Increased number of VBDs
Maximum number of VBDs per VM has increased to 255
Increased number of VBDs
Maximum number of VBDs per host has increased to 4096
Enhanced Active Directory Support
Delivering improvements for customers with large numbers of objects within their Active Directory, including improved login times.
Increased Size of Dom0 Disk Partitions
By moving log files to a larger, separate partition, we enable more detailed logs to be held, over a longer period of time, improving the ability to diagnose issues. Simultaneously, this alleviates demands on Dom0’s root disk, which can sometimes lead to out of space issues, due to log file disk space consumption.
Single-threaded Storage IO
Customers should notice significant improvements when using high performance/low latency storage.
Networking and Storage IO
Higher throughput for Networking and Storage IO in aggregate usage scenarios.
