Review: VMware vSAN Simplifies Data Access and Sharing for Feds

Virtualization solution also creates backup in case of technical disaster.

Within the federal government, virtualization software makes up the backbone of data storage initiatives. A solid storage virtualization platform boosts an agency’s ability to deliver vital citizen services without delay.

An effective platform such as VMware vSAN allows agencies to better manage compute and storage capabilities within an aggregated platform instead of taking the traditional approach of point solutions, which are built to handle specific needs or desired capabilities.

A centralized solution like VMware vSAN also provides agencies with an affordable approach that simplifies storage, as well as access to and use of that data.

Making Provisioning and File Sharing Dynamic

Having worked with previous versions of vSAN, I was accustomed to the ease of use and intuitive navigation of the platform. However, one feature that impressed me in vSAN 7 was the support for file-based persistent volumes for Kubernetes on vSAN data stores.

Using this version of VMware vSAN, developers can dynamically create file shares for their applications and have multiple pods share data. Persistent volumes are important for applications that save client data from one session for use in the next. Kubernetes supports these workloads.

vSAN 7 now supports NFS version 4.1 and version 3 protocols while offering integrated file services, so it’s easier for agencies to provision and share files. For example, government users can provision a file share from a cluster via NFS version 4.1 and version 3, reducing the time to stand up a file share.

How Disaster Backup Promotes Effective Data Storage

One of the most vital characteristics of effective data storage is the role backups play if an agency experiences a disaster. The federal government has always embraced continuity of operations planning (COOP), and protecting data storage has always been a part of that. Thankfully, VMware vSAN integrates disaster recovery into its main platform.

Managed as a core component of a vSphere environment, vSAN is built on an optimized input-output data path in the vSphere hypervisor for exceptional performance. This means that separate administration tools and connections are not required, which simplifies management, particularly in locations that have little or no local IT staff, such as a disaster recovery site.

With solutions like vSAN, agencies of all sizes can benefit from reliable COOP backup and planning no matter what happens to the production environment. This will help ensure that they’re back up and running quickly during a crisis.
