VMware VSAN shakes up the virtual storage realm

VMware followers shared tips and news on Twitter following the general availability release of VMware VSAN.

In early March 2014, VMware announced general availability of VMware Virtual SAN (VSAN) to draw a strong reaction on social media networks, specifically Twitter. VMware VSAN is the virtualization company's first software-defined storage product.

But is everybody happy about it? VMware VSAN could tempt some medium-to-large companies that want to use existing hardware for storage. But others -- including VMware partners that occupy the virtualized storage space -- might not be pleased by this release. Here is what people are saying on Twitter:

VMware took another step in expanding its virtualization scope with its first offering in the storage virtualization space. VMware Virtual VSAN puts software-defined storage directly in the kernel of vSphere 5.5 and sends notice to several partners in the same space that VMware may have to step on a few toes to fulfill its vision of the software-defined data center.

VSAN costs $2,495 per processor. VSAN for desktop virtualization costs $50 per user. Companies investigating VSAN should weigh the costs versus upgrading storage hardware. To help with the decision-making process, several VMware followers, including Florian Grehl, have put VMware VSAN cost calculators on their sites.

VMware's foray into virtual storage has appeal to enterprises looking at converged infrastructure systems and those looking to extend the life of their existing hardware infrastructure thanks to the pooled storage capabilities of VSAN.

Despite a significant amount of beta testing for VSAN, it isn't unusual for many 1.0 releases to have various issues that either will require a fix or a knowledge-base article to get around.

Some IT professionals felt the cost to implement VMware VSAN was too high, particularly for SMBs, leading to speculation that smaller businesses may consider a physical SAN to meet their storage needs.

Do you plan to implement VMware VSAN?
where and when it makes sense...
For me, at Pea Soup Hosting, the VSAN benefits far out weight the issues. We were very careful in hardware selection, ensuring good queue depths for the controllers for example and therefore we were not hit when the hardware compatibility list changed recently. For the initial build we had to start on one disk until we could get far enough into the build to stand up the VSAN but thereafter we have not looked back and the Pea Soup vCloud was born. Not a traditional lump of storage in sight, massive amounts of performance and throughout and very cost effective for a cloud service provider. Our company Pea Soup is built upon this technology and it works really well. It won't take long for others to catch up but right know we can reap the benefits against our competitors.
