Better Together: Optimizing VMware vSphere 6.0 Deployments with Dell EqualLogic PS Series
Although server virtualization provides enormous benefits for the modern data center, it can also be daunting from a storage perspective. Provisioning storage to match the exact virtual machine (VM) requirements has always been challenging, often ending in a series of compromises. Each VM will have its own unique performance and storage requirements; this can create over-provisioning and other inefficient uses of storage. A virtualization administrator has to try and match a VM’s storage requirements as close as possible to storage that has been pre-provisioned. Provisioning in this way is time consuming and does not possess the VM-level granularity required to meet the specific needs of the applications running in a VM. To exacerbate the problem, often, over the lifetime of a VM, the storage requirements for a VM will change, which requires ongoing diligence and review of the storage platform and manual intervention to meet the new requirements.
VMware vSphere 6.0 introduced the biggest change to the ESXi storage stack since the company’s inception with the inclusion of vSphere Virtual Volumes (VVol). VVol helps to solve the challenge of how to match a VM’s storage requirements with external storage capabilities on a per VM basis. We found that VVol when combined with Dell EqualLogic PS Series arrays become a powerful force in the datacenter.
In this brief, we call out some storage-related highlights of vSphere 6.0 such as Virtual Volumes, and then take a close look at how they, as well as traditional datastore stored VMs have been enhanced and packaged by Dell Storage into the EqualLogic PS Series storage solution. We will show how Dell and VMware have combined forces to deliver an enterprise-class virtual server and storage environment that is highly optimized and directly addresses the performance, availability, data protection and complexity challenges common in today’s business-critical virtualized data centers.
