During an upgrade from a vSphere 6.0, I’ve found a really strange iSCSI storage issues where all the VMs on the iSCSI datastore were so slow to become un-usable. First I was thinking about drivers or firmware, in the hosts and in the NIC (1 Gbps) or the firmware on the storage.
Reading Time: 2 minutes On October 2017, I wrote a post about a possible issue with vSphere 6.5 and 10 Gbps NICs (mostly standard on new deployment). The final result was a PSOD (Purple Screen Of the Death) and no solution was available (yet). VMware KB 2151749 describe this issue as related to possible upgrade at vSphere 6.5. But other customers have report the issue also on new deployment. Veeam, one of the first vendor to found this issues (from their customers), reports that the issues is due to network-intensive activities such as backup over NBD or vMotion randomly triggering one.

Reading Time: 17 minutes This is an article realized for StarWind blog and focused on the design and implementation of a stretched cluster. A stretched cluster, sometimes called metro-cluster, is a deployment model in which two or more host servers are part of the same logical cluster but are located in separate geographical locations, usually two sites. In order to be in the same cluster, the shared storage must be reachable in both sites.

Reading Time: 2 minutes VMware 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. These replace the traditional vmfsSparse format (redo logs).
