A: The density improvement depends on your users’ workload varying form 10% to 100%.
10% for users only editing Microsoft productivity applications
100% for Multimedia users mainly playing Video on their screens
For Office workers workload (text editing, pdf browsing and light web browsing), we measured a 16% density improvement with the APEX 2800 (versus without)
A: No. The drivers are not made available by VMware in their repository, so this can’t be used –we tried since the APEX is fully managed through View Administrator, once installed- You need to download the drivers manually and install as per QSG (techsupport.teradici.com).
A: It could, but will be dependent on your Server CPU Utilization when your users are experiencing a bad user experience. If your Server CPU is close to 70%, the card will give back CPU cycles which will be used right away by ProE application to deliver a better rendering.
A: No. We are currently working with Server OEM to bring the cards into their Blade servers. We will present some exciting news at upcoming VMworld 2012 in San Francisco.
A: The card Teradici APEX 2800 will greatly reduce the need for a second vCPU for video or flash workloads.
A: The APEX 2800 will reduce the CPU usage of the PCoIP server process offloading the PCoIP related encoding tasks. Whitepapers are available at techsupport.teradici.com.
A: That’s correct. We are working with Server OEMs, including HP and IBM, to solve this limitation.
A: Yes, the card is installed into your ESXi server.
A: No. The card is compatible with View 4.6 and later and going forward we will maintain compatibility every time VMware releases a new version of View.
A: Yes, we will be announcing some exciting news at VMworld in San Francisco.
A:.-The current limitation of 64 displays (not VM) is driven by the maximum display resolution supported, currently hard coded to 1920x1200. However, we plan to enable IT Administrators the option to configure their max displays resolutions in our next release: if higher (aka 25x16), you will have less than 64 displays , if lower (12x10), you will reach over 120.
A: Yes. Pivot3 has been testing the card with great success. Don’t hesitate to contact us at APEX2800@teradici.com or Pivot3 directly if you would like more details on this.
A: Yes, View 5.1 is supported.
A: The card is available worldwide and has a list price of $1995 in the USA.
A: No, the APEX 2800 will not replace a GPU. IT will actually complement the physical GPU card when it is supported on VMware View deployment The APEX 2800 offloads the PCoIP encoding tasks, versus the GPU offloads the rendering of the displays.
A: Yes, you need to install a driver on each VM for them to be eligible for offload. A driver on the ESXi server is also required. For more information visit techsupport.teradici.com.
A: Not currently. As of now it requires a PCIe x8 electrical slot to work.
A: You can see a CPU reduction as soon as with one VM. The card is only sensitive to workload, not number of VM. The more pixels changes on the displays (up to 64), the more benefits the card will bring in terms of CPU Reduction.
A: Please refer to QSG available on techsupport.teradici.com
A: It is a manual installation. The driver on ESXi host needs to be installed for it to be recognized by the host.
A: No, the APEX 2800 will not solve any network latency issues.
A: Please contact: firstname.lastname@example.org
A: It is currently full-height half-length PCI-e x8 electrical . Half-height Half-length x4 will be available in CY Q4 2012.
A: No. The display of the VM can only be offloaded if the drivers on both the VM and ESXi host are installed.
A: We have an APEX calculator available on our website which can help understand better the different benefits of the card.
A: That’s correct, APEX + GPU will be a great combination in your Server.
A: It all depends on the workload of your users; you can see an improvement from 10% to 100% per core.
A: Each card automatically and dynamically offloads the most active 64 displays so even at 150 or 200 VM, the card will always protect against unforeseen multimedia peaks hence ensuring and protecting a great user experience as loads change. If the card was used to increase server consolidation ratio, the benefits will less than if you were able to offload each of the VM.
A: As long as your users’ workload is stable and peaks can’t create a push towards the 75% CPU utilization threshold, the card would currently have limited benefits for you. However, because the card is able to go more in depth around the PCoIP protocol (pixel encoding versus block of pixels, etc.), we have seen some user experience improvement for some specifics workloads.
A: The consolidation ratio, or server density, is the number of VM that a single Server can support based on its technical specifications. You have to differentiate Theorical number (only reached with tasks workers) versus actual (which adds some CPU buffer to any deployment to protect the user experience).
A: The card only offloads the displays rendered for the VMs supported by that specific Server.
The APEX 2800 is compatible with DRS/vMotion meaning that if a VM gets “vmotioned”, it will still be eligible for offload, in the same user session, as long as the new Server also has an APEX 2800 installed.
A: Yes, please refer to whitepaper “Performance study” at techsupport.teradici.com.
A: Xangati will gather the statistics on PCoIP generated by the card however, it will not directly monitor the card itself.
A: Not much. However, should your users start doing more multimedia activities or you have users with more unpredictable workloads, the card will help.
A: Same as VMware View guest OS.
A: Shared GPU support is a View feature and does not require APEX 2800. However, bundling both APEX and GPU will bring great benefits to your deployments.
A: The card sees “displays”. In your example, you have 100 displays and the card will dynamically and seamlessly offload the most active 64 displays (out of 100).
A: That’s correct. PCoIP protocol only sends pixels that have changed from the “previous” screen.
A: We are working with OEM partners to bring the benefits of the cards to their System.
A: The card is a VMware View enhancer. It has the same restrictions and compatibility as VMware View in terms of OS supported.
A: Because of the slots limitation, we support up to 2 cards per Server, or 128 displays.
