VMware has just announced the release of ESXi 5.5 and the contest with Hyper-V 2012 R2 couldn’t be any hotter.  In this post, we will compare some of the configuration maximums for the two hypervisors.   In addition to raising the limits within the hypervisor, each product has added a ton of new features to draw buyers and existing customers to purchase or upgrade to one of these products.

As seen in the table above, the configuration maximums for both products are eerily similar. But considering that just a couple of versions ago, Hyper-V was not even close on the feature set and scalability of VMware, it has come a long way in a short time to prove that it is here for a fight. In fact in terms of scalability, Hyper-V 2012 R2 boasts of higher maximums than VMware.   In addition,  Hyper-V 2012 R2 includes some really cool features that extend the Hyper-V replica to chain from the DR location to a secondary DR location, thereby raising the bar much higher in terms of high availability.

From our perspective, we work great with VMware and Hyper-V and the new versions of both the products get us all excited to deliver world class protection for both.  In addition, Unitrends Enterprise BackupTM will be able to leverage the higher configuration maximums thereby simplifying deployment and management of the backup storage pool.

What are your thoughts on the release of ESXi 5.5 and Hyper-V 2012 R2? We would love to hear from you.
