As a delegate for Tech Field Day 6 in Boston, I was introduced to SRM Replication as well as ZeRTO a third party replication tool. They seem to be as different as night and day but are they? Both work within the vSphere environment to replicate virtual disks regardless of storage type, and apparently hook into the same location within VMware’s API stack. This shows a maturity of VMware’s API stack that until now has been unknown and secret. In this one area, Microsoft Hyper-V is beating VMware vSphere: The availability of well known APIs that are easy for Third Parties to use. I now see a change in VMware’s behavior, can they continue this growth?
