VMware vSAN has grown very fast in those years, not only in the number of versions (quite impressive) but also in the customers’ adoption, with more than 14000 organizations using vSAN and with a 110% growth year-over-year.

Reading Time: 3 minutesIf you are using Veeam Backup & Replication with a VMware vSAN datastore you are probably following the Veeam KB 2273 (Configuration for VMware VSAN).

Maybe also one per host.

Reading Time: 2 minutesThe vExpert vSAN program is a specific VMware vExpert (sub)programs focused on the vSAN product. The idea to have specialized groups of vExpert was to bring again (like at the origins) the vExpert program as an “elite” program. After the vExpert vSAN 2016 and 2017 lists, now VMware has just announced the vExpert vSAN 2018 new list. I was honored to part of this list again, and that’s pretty exciting, considering that I’m there from the first list.

The interesting aspect of this tool is that it’s very easy and fast to be deployed and that it can work fully in offline mode!

Reading Time: 2 minutesVMware vSAN should manage better VM snapshots compared with traditional storage and VMFS datastores. The reason is the new (v2) on-disk format in VSAN 6.0 and the new filesystem that is used: VirstoFS. VirstoFS is the first implementation of technology that was acquired when VMware bought a company called Virsto a number of years ago. Also there is a new sparse format called vsanSparse.
