Since we announced the "full" open sourcing XenServer back in 2013, there were many questions and concerns whether or not was Citrix continues to invest in Citrix XenServer committed. Some even hinted that somehow Citrix XenServer had set chosen as commercially supported product and technology.
nothing could be farther from the truth.
Citrix XenServer is alive and well! It supplies about 40% of the Citrix XenDesktop implementations, and 60% of the Citrix Cloud Platform-based production private and public IaaS cloud infrastructure environments. It continues as the underlying server virtualization platform for some of the largest private and public institutions around the world to power enterprise data center modernization projects.
When I discussed at this year's Citrix annual user conference, Synergy 2014, Citrix has, and will continue in the robust future roadmap of Citrix XenServer.
On July 8, 2014, we have the latest technology to invest in existing Citrix XenServer customers with active Subscription Advantage preview next release of Citrix XenServer codenamed Project Creedence
Here is a brief summary of latest features in Citrix XenServer Tech Preview contained .:
power
While earlier versions concentrated on the scale, this Tech Preview adds to deliver this through significant performance improvements in networking and storage. This includes an in-memory read cache, support for Tapdisk3, General Receive Offload (GRO) and the reintroduction of Workload Balancing (WLB).
scalability
The new 64-bit Linux control domain (dom0) removed a number of bottlenecks that were dom0 32-bit Linux available with, and gives us the opportunity to integrate newer devices, with less kernel memory limitations on the number of devices in a system. An immediate advantage of a 64-bit Dom0 is that we can use 64-bit compiler settings to take advantage of modern processor extensions, while a 64-bit Dom0 previous restrictions eliminated vgpu scalability.
Supportability
Significant numbers of new guests support and hardware compatibility dramatically expanded
vgpu
Improved scalability of vgpu -. yet the only true solution vgpu the world for graphics-intensive workloads for virtualized environments and optimized for XenDesktop. Now scales to 96 VMs compared to 64 VMs on Citrix XenServer 6.2.0 SP1.
DVSC
override to the previous deprecation notice for the Distributed Virtual Switch Controller (DVSC).
TCO reduction
read cache, TRIM and UNMAP support for VDI space reclamation.
