VMware, Microsoft, Citrix, and Red Hat Cost Comparison

In part one of Cost to Build a New Virtualized Data Center, we discussed the basic software costs for a virtualized data center based on VMware vSphere 6.0, Citrix XenServer 6.5, Microsoft Hyper-V 2012 R2 and 2016, and Red Hat. If you missed that, please click here to review before continuing.

This post will take that original premise and expand it to include storage with a view to moving the entire environment toward a software-defined data center.

Over the last couple of weeks, I have been thinking about costs relating to a building a new virtualization-based data center. “What?” I hear you say. “Everywhere is virtualized—there is no such thing as a greenfield site anymore!” I would have said that myself, but in the last month I have come across three, one of which is a company worth over a billion pounds.

I thought I would have a look for a third-party switch for XenServer, but it seems that XenServer is a third-rate citizen in this space, as there is no Cisco Nexus 1kV available for XenServer, even though Cisco previewed it at Citrix Synergy Barcelona in 2012.

Citrix XenServer Creedence Tech Preview

DataCenterVirtualizationCitrix100x30Citrix has announced the availability of the “Creedence” tech preview of the next version of XenServer, building on the open-source Xen Project’s Creedence alpha.4 release. The biggest change in Creedence is the move to an all 64-bit implementation. While the Xen hypervisor has always been 64-bit and can run both 32 and 64-bit guest operating systems, the XenServer control domain, dom0, has not. Dom0 is where the management tasks run, and more importantly here, it is where the physical hardware is controlled. Moving to a fully 64-bit implementation will enable significant performance and scalability improvements as well as important changes to hardware support.
