VDI Calculator v6.2 is Now Available w/ Haswell support

Today I am announcing the general availability of the new VDI Calculator v6.2. This version introduces support for the Xeon E5-2600 V3 family of processors, based on Haswell microarchitecture, and Configure To Order (CTO) configurations for the Nutanix NX and Dell XC series.


  • Haswell E5-16xx/26xx v3 processors – Haswell is the successor to the Ivy Bridge microarchitecture, which is the de facto processor in all Nutanix hardware platforms today. The VDI calculator now accepts Haswell E5-16xx/26xx v3 processors up to 18 cores. Please note that Haswell configurations can also be used for traditional SAN (3-tier) deployments. According to Intel, “From a performance perspective we are delivering worldwide performance levels, tripling performance [thanks to] the Xeon V3’s 18 cores [that] offer a 50 percent increase over the prior generation”. On Nutanix NX and Dell XC the storage performance improvements are visible as you can see in the graph below.




During tests with LoginVSI Knowledge worker profile we are seeing a 15 to 25% performance improvement coming from the Haswell processor, but also from the improved memory speed. On a Nutanix NX 3460 (2x10c) we now see around 125 2vCPU desktops with the aforementioned LoginVSI profile. Despite tests, I would strongly recommend a proper assessment to define the resources required by your organization’s VDI deployment.


  • Configure To Order (CTO) – Both Nutanix and Dell now provide support for Configure To Order (CTO). With this, you have the ability to right size your hardware platform to exactly meet the need of your workloads by choosing the right amount of compute, memory and storage that your VDI solution need. Given that the configuration is now flexible I have removed the rigid selection for specific Nutanix and Dell models, opening up for choice. Please make sure you verify the available models with Nutanix or Dell before setting a specific ‘Socket per Host’ and ‘Cores per Socket’ configuration.
