Reading Time: 4 minutesThe new VMware vSphere 6.7, recently available in GA, increase all configuration maximums to new limits (compared to the v6.5 and previous versions). Maybe we can say with no limit, or at least, to be serious, with really huge numbers compared to the actual needs and the existing compunting power. Those new limits are both for scalability aspect, but also to fit with possible performance requirements, considering that a bigger number of business critical applications are going in the virtual environment.

Reading Time: 2 minutesThere are only 5 months until VMware vSphere 5.5 will go End of Support, that will mean no more updates and possible limited support from VMware. The End of General Support for vSphere 5.5 is September 19, 2018. To maintain your full level of support and subscription services, VMware recommends upgrading to vSphere 6.5, or to a newer version. With version 6.5 U1, VMware has extended the general support for vSphere 6.5 to a full five years from date of release, which means the general support for vSphere 6.5 will end November 15, 2021. Quite […]

Reading Time: 5 minutesVMware has just released the new version of vSphere 6.7 that includes ESXi 6.7 and vCenter Server 6.7, and, of course, it’s the foundation for vSAN 6.7! There are several news, improvements and new features. Most are well described in the vSphere 7.6 launch page.

Reading Time: 9 minutesThis is an article realized for StarWind blog and focused on the pro and cons of an upgrade to vSphere 6.5. See also the original post. VMware vSphere 6.5 is the latest version of the enterprise server virtual platform from VMware, but the new beta it’s already there for testers. Actually the next version it’s (in the beta) and you can register at https://secure.vmware.com/43478_vSphere_Beta_Reg.

Reading Time: 3 minutesNow that the PSOD on vSphere 6.5 and 10 Gbps NICs issue is finally solved seems that vSphere 6.5 critical bugs are closed, but it’s not totally true. 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 minutesOn 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: 3 minutesIn the VMware ESXi 6.x partitions layout, usually, there is a partition called “scratch” that hosts the log, the updates, and other temporal files. Scratch space is configured automatically during installation or first boot of an ESXi host and is not required to be manually configured. If you install ESXi on a local hardware disk (or also if you are using a remote LUN in “boot from SAN” mode), this partition is built during the installation phase (it’s 4 GB Fat16 partition created on the target device during installation, if there is sufficient space). If […]
