The time is right for virtualising HPC systems

Virtualisation of high performance computing is more viable than ever with VMware vSphere Scale-Out Edition on Dell EMC Ready Solutions for HPC.

 

In today’s enterprise IT shops, everybody understands the benefits of server virtualisation. When you virtualise servers, you can turn a single physical host into multiple virtual systems, each with its own operating system and applications. You can then greatly increase the utilisation of the physical systems while accelerating the provisioning of resources, increasing IT responsiveness and simplifying data protection.

Everybody gets it, and everybody is doing it — and not just for servers, but also for storage and network resources. But — wait — you’re different, and what about high performance computing systems? Despite the wide acceptance and well‑understood value proposition for virtualisation of rank-and-file data centre resources, many organisations have yet to virtualise their HPC clusters.

Why so? For starters, there is a common perception that virtualisation comes with a performance penalty stemming from the addition of a layer of software between the operating system and the hardware. Although this may have been true years ago, the reality is different today. Advances in hypervisors and hardware virtualisation support in x86 systems have yielded big increases in performance for virtualisation HPC workloads. With these advances, your IT team can now gain the benefits of virtualisation for HPC workloads while delivering performance that is comparable to bare metal for many workloads.

Another perception in IT shops is that per‑core licensing costs make virtualisation prohibitively

expensive for HPC clusters. Today, VMware addresses this concern with VMware vSphere Scale-Out Edition, a virtualisation SKU designed for big data and HPC workloads. This software suite delivers all of the core vSphere features required for big data and HPC workloads with cost‑effective license packs for eight CPUs.

And finally, there is also a perception that if you virtualize an HPC environment, admins won’t be able to access all of the features they need. Here again, with vSphere Scale-Out, the reality is quite different from the perception. The vSphere Scale‑Out package offers many of the popular features used in other VMware environments, along with the support of a broad ecosystem of technology partners who provide value‑added services.

Compelling benefits

OK, now that we’ve addressed the perception-vs.-reality issues, let’s talk about some of the specific benefits that come with the virtualisation of HPC systems. For starters, virtualisation adds a flexibility, operational efficiency, agility and security at levels that cannot be achieved in bare‑metal HPC environments.

For example, system expansion and contraction are simplified when provisioning is done with virtual machines. Cloning a VM as a new member of a cluster takes minutes. Virtualisation with vSphere Scale-Out also gives you the ability to move workloads with VMware vSphere vMotion for maintenance or proactive fault avoidance.

Even better, virtualisation can help you centralise bare‑metal islands created by individual departments running HPC workloads. This centralisation positions your team to drive up resource utilisation and to give more users access to HPC resources. And by using familiar virtualisation management tools, your IT shop can assign exactly the compute and storage power that is needed by any one team — without dedicating significant hardware to that one purpose.

Bringing it all together

When you’re ready to roll out virtualisation HPC resources, Dell Technologies and VMware can help you bring together everything you need. We make it easy with enterprise-grade Dell EMC Ready Solutions for HPC with VMware.

These solutions deliver a new level of flexibility and agility to HPC. Rapid provisioning of infrastructure on‑demand enables speedy iteration and scale‑out — so you can spend more time helping people gain insights from HPC and less time on setup and retooling. The solutions also simply day‑two operations, such as ongoing provisioning and infrastructure maintenance, and help your team avoid planned downtime through live migration features.

Ready Solutions for HPC with VMware also address data governance and security concerns. Security isolation prevents VMs from seeing each other’s data in the same cluster. Each VM can access only the virtual disk files designated for it. This adds up to increased VM and host security for data.
