Most of you probably know that VMware recently, for the first time, started hiring a dedicated End-User Computing sales force. VMware has been hiring hundreds of EUC focused sales reps and SEs across the globe, which some are coming from Citrix.
I had the opportunity to talk to few of those new VMware employees and better understand what motivated them to come to VMware. Some of these new employees looked for me as their technical and/or pre-sales resource. I also would like to mention that I feel profoundly honored to learn that I am a respected professional at Citrix and that many of you follow my articles, comments and blogs. Thank You!!!
My initial thoughts were that these sales reps moved to VMware for more money, but I was proved wrong. The main reason for the vendor move according to these new VMware employees was the vSphere stack. What does that mean? Well, that means VMware is in the best position on the marketplace compared to any other EUC vendor to leverage the vSphere hypervizor features and technologies because VMware owns the stack.
And how does that affect Citrix? The large majority of Citrix XenApp and XenDesktop deployments are currently running on VMware vSphere platform.
I won’t make this article about VMware versus Citrix, but I would like to provide better exposure to the VMware vSphere platform features that are only leveraged by Horizon View today, representing gigantic CAPEX and OPEX saving to enterprises of all sizes.
- Content Based Read Cache (CBRC)
CBRC help address some of the storage performance bottlenecks and the increase of storage cost for VDI. CBRC is a 100% host-based RAM-Based caching solution that helps to reduce read IOs issued to the storage subsystem and thus improves scalability of the storage subsystem while being completely transparent to the guest OS. VMware tests have identified a boot storm reduction of approximately 80% on peaks IOPS, ~45% on average IOPS, ~65% on peak throughput and ~25% on average throughput. For additional information I recommend you reading my previous article Understanding CBRC (Content Based Read Cache).
- Space Efficient Disks (SEsparse)
Horizon View 5.2 leverages a new vSphere capability that implements a new VM disk format that allow for grain size reduction & increased efficiency allocated blocks by filling it with real data. Unused space is reclaimed and View Composer desktops remain small, saving on storage capacity. For a deep-dive on the technology read Space-Efficient Sparse Virtual Disks and VMware View. Space Efficient Disks reduces storage capacity requirements, lowering CAPEX for Persistent Desktops, even on lower-tier hardware.
- 3D Graphics (vSGA and vDGA)
Horizon View 5.2 leverages a new vSphere capability that enables shared access to physical GPU hardware for 3D and high performance graphical workloads. Virtual desktops still see abstracted VMware SVGA device for maximum compatibility & portability, but use Accelerated 3D Graphics, enabling truly high performance graphics in a cost-effective manner with multiple VMs sharing a single GPU resource. Additionally, the solution is fully compatible with hosts lacking physical GPUs (for vMotion, DRS, etc.). Refer to my article How to improve VDI with Hardware Accelerated 3D Graphics for a deep dive on 3D technologies.
[UPDATE] Citrix is also leveraging vSphere vDGA and presenting it via XenApp and/or XenDesktop according to my readers.
- View Composer Array Integration (VCAI)
VCAI allow administrators to take advantage of the storage native snapshot feature within the normal administrative workflow of Horizon View and View Composer. VCAI integrate with NAS storage partner’s native cloning capabilities using vSphere vStorage APIs for Array Integration (VAAI). VCAI speeds up provisioning of virtual desktops while offloads CPU consumption and network bandwidth.
While both Horizon View and the vSphere platform offer many other features that help organizations with TCO reduction, only Horizon View leverage the platform features mentioned in this article, providing a much increased CAPEX and OPEX reductions.
As VMware moves forward with the Horizon Suite it is reasonable to expect that this platform integration be further enhanced providing yet more benefits to organizations. In my VMworld session EUC4764 – What’s New and Next for VMware Horizon View I provided some examples of integration opportunities ahead of us, and that include vSAN, vFlash and NSX.
I am sure people also move the other way, from VMware to Citrix, and they have they own reasons. I’m just demonstrating few of the reasons why it’s so exciting to work for VMware EUC.
