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.
Part 2a of this series concentrated on Hyper-V 2012 R2 and 2016 as well as vSphere 6.0 regarding the addition of a local distributed storage solution: DataCore Virtual SAN in the case of Hyper-V 2012 R2, Storage Spaces Direct with Hyper-V 2016, and VSAN 6.2 with vSphere 6.0. You can review that article here.
This article continues from that second article of the series and finishes the addition of a local distributed storage stack to XenServer and RHEV. Once again, our compute unit of choice is the Dell 730xd with two 10-core CPUs and 256 GB of RAM. As stated in the previous post, we need to add some local storage in each node. These compute nodes can, depending on the choices made during the configuration, take up to twenty-four disk drives. For the purposes of this article, we are assuming that data locality is required for performance and that there is a need for an all-flash array. We chose to go with two 400 GB SLC drives for cache and four 800 MLC drives for capacity, giving a total raw capacity per node of 4 TB. There may be further hardware requirements depending on the chosen solutions for each hypervisor, but that will be called out in the relevant vendor sections.
