Are there differences between VMware’s EVO:RAIL partners?

VMware has partnered with several companies to offer EVO:RAIL, and while the underlying technology is the same, there are subtle differences.

Editor’s note: The announcement of EVO:RAIL at VMworld and VMworld Europe 2014 showed the importance VMware is attaching to hyper-converged infrastructure. This first of two articles examines the technology behind EVO:RAIL and how the different OEM partners vary. The second article will show what use cases apply to EVO:RAIL and discusses the pros and cons. The original German language version of this article can be found on SearchDataCenter.de.

If you look at the technological basis of EVO:RAIL, it is nothing more than preconfigured and preinstalled blade servers with integrated networking and storage resources. VMware doesn´t build the appliance itself, but relies on hardware partners like HP, Dell or Fujitsu that place their own server hardware at the heart of their respective EVO:RAIL offering. VMware then adds its own software stack consisting of vSphere, vSAN, vRealize Log Insight and the newly-announced EVO:RAIL engine.

The technological basis of VMware EVO:RAIL

EVO:RAIL isn´t distributed by VMware itself, but through the distribution channels of its OEM partners. As these EVO:RAIL partners need to certify their hardware, VMware promises the same rapid deployment and configuration process throughout the different vendors. This is enabled through the new EVO:RAIL engine that, according to VMware, fulfills more than 200 background tasks during installation, like installation of databases or deployment of web servers.

The 2U appliance can be scaled out to four appliances. One appliance is said to provide enough performance for 100 virtual machines or 250 virtual desktops. For both use cases, VMware provides two different versions that differ only in the integrated software (VMware Horizon 6 for VDI). As of the time of this writing, all appliances use the dual socket Intel Xeon 2620 v2 CPUs with six cores, but according to some vendors there will be EVO:RAIL appliances with Intel Haswell CPU Xeon E5-2600 v3 shortly.

Additionally ,there are 192 GB of memory, 146 GB ESXi boot storage, 400 GB SSD read/write cache and three 1.2 TB vSAN storage. Network connection is realized through two 10 Gigabit Ethernet jacks (RJ45 or SFP+).

Differences between OEM partners

Little is known yet about the differences between the EVO:RAIL appliances that the various OEM partners are building. We simply haven’t seen the shipped appliance yet, and most vendors are targeting the first quarter of 2015 for general availability.

Due to the certification process the hardware has to go through, there shouldn´t be too many differences regarding the performance of the various EVO:RAIL appliances. Nevertheless, the underlying hardware of each vendor has its influence on performance. For example, Fujitsu points out in its marketing materials that it maintains a leading position in the official VMmark Benchmark.

Normally customers do not get insights into specific hardware components, hence there could be differences in the quality of certain peripheral parts of the particular appliances.

The decision for one of the different vendors (HP, Dell, Fujitsu, NetApp, EMC, Hitachi Data Systems, Inspur, NetOne and Supermicro) at the moment is most probably based on regional availability and the existing infrastructure in a customer’s data center. Where there already is hardware or management software from one of the vendors, chances are high a customer would choose the same vendor for his EVO:RAIL appliance. Obvious differences between the various VMware partners only exist in regard to the surrounding services and the existing ecosystem of the vendor.

For example, HP integrates EVO:RAIL into its management platform OneView, whereas Dell makes use of Nexenta’s software-defined storage solution NexentaConnect for VMware vSAN and VMware Horizon. A similar cooperation exists between Nexenta and Supermicro. Hitachi, on the other side, stresses the deep integration into its Unified Compute Platform (UCP).

For all the technical similarities between VMware’s EVO:RAIL partners it seems possible that we could see different prices. It wouldn´t be the first time the server market has seen this approach between competing vendors.

Have you noticed the differences between VMware’s EVO:RAIL partners?

The one main noticeable difference we have noticed between VMware EVO:RAIL partners is the speed between initial deployment via start-up to fully functioning. The time difference between the partners seems to be the one feature we have noticed above all others. There are subtle differences between the partners that involve the use of switching or selecting OSs and other security functions, but the main difference my company has noticed is the speed upon initial deployment.

Well, that's interesting. Doesn't VMware promote EVO:RAIL to be ready for production within 15 minutes? Regardless of the OEM? I guess this was a marketing claim from the beginning, but with the same EVO:RAIL engine running on all appliances - why would it take different deployment times?

The biggest omission here is what EMC have done to the EVO:RAIL..... they seems to be the only QEP that has bothered to think about what 'value-add' they can offer to end users... every other partner just appears to box-shift!

They've re-written the UI, you use VSPEX Blue Manager rather than the underlying EVO:RAIL Manager.

You get VDP-Advanced so have a backup solution...

You get RecoverPoint for VM, so have a replication/DR solution....

You get Cloud Array VE, so can offload cold data to cloud storage....

Although you also get a price hike compared to the other box shifters... =)

I see no technical difference between the two. The existing difference is only based on the availability of the service provider and data center infrastructure.
