Reading Time: 5 minutes VMware vSAN 6.7U3 it’s out and maybe you would like to upgrade your environment. In my opinion, one reason to upgrade is to finally have the automatical proactive rebalancing feature. You can automate all rebalancing activities with cluster-wide configuration and threshold settings. Prior to this release, proactive rebalancing was manually initiated after being alerted by vSAN health checks.

Reading Time: 4 minutes Last week, VMware has announced the future release of VMware vSphere 6.7 Update 3, that means, of course, also the new vSAN 6.7 Update 3 (vSAN is totally integrated in vSphere code). Unfortunately, has happened in past, this is just a product announce, without provide the code of it and the date of General Availability (GA) release date (but I guess will be on VMworld US 2019). I usually prefer talk about what exist now and see the release notes. The products are now GA and, most important the hardware compatibility and the software interoperability matrix have […]

Reading Time: 2 minutes StarWind Virtual SAN eliminates any need in physical shared storage by simply mirroring internal hard disks and flash between hypervisor servers. Its solution use a hyperconverged approach to maintains high performance and data high availability on minimalistic resources (it’s build around a two nodes architecture).

Reading Time: 3 minutes VMware vSAN does not need anymore an introduction: is the Hyperconverged Infrastructure (HCI) solution from VMware integrated in the ESXi kernel… and is growing more and more in the last years and more more than 500,000 VMware customers for years. There are different way to implement a vSAN solution and one common approach remain to build yourself using vSAN Ready Nodes or certified hardware components.

Reading Time: 2 minutes The VMware vSAN release catalog provides critical information to vSAN build recommendation engine. It will be updated when there are new releases or critical patches and, of course, it’s very important to keep the local copy up-to-date. The vSAN health check feature, will periodically ensure that the local copy of vSAN release catalog is up-to-date.

Reading Time: 2 minutes With VMware vSAN you can use VMware vSphere Update Manager (VUM) to update all the software part, but it can also be useful to manage some hardware related updates. Usually you have to check BIOS version (for example for Spectre and Meltdown bugs), but also the other firmware.

Reading Time: 5 minutes VMware vSAN is a powerful hyperconverged solution, but sometimes still lack of some information or usability. In most cases the health engine is working well and automatically, but in other case it needs your attention and manual operation. One example is the vSAN Disk Balance alarm that sometimes happen in your cluster and bring your healt status no more “green”. This warning just indicate that that the cluster is imbalanced and there are disks that are high on space usage while others are very low, that potentially can make your cluster no more optimal.

Reading Time: 2 minutes Some weeks ago, VMware has discover a possible issue in all VMware vSAN 6.6 and 6.7 cluster, related to hot (or also cold) disk-extend operations. Applications such as databases report in-guest data inconsistency on a VMDK that has been extended while residing on VMware vSAN 6.6 and later. More information of this issue are provided in the VMware KB 58715 (Virtual Machines running on VMware vSAN 6.6 and later report guest data consistency concerns following a disk extend operation).

Reading Time: 6 minutes With the announce of the new vSphere 6.7 Update 1 you should expect also a new version of VMware vSAN (the bits are included in vSphere) and that’s it: vSAN 6.7 Update 1 (strange that has not been used the name vSAN 6.8). 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.
