Reading Time: 2 minutes There is a big issue in vCenter Server, with sensitive information disclosure vulnerability in the VMware Directory Service (vmdir). Under certain conditions vmdir that ships with VMware vCenter Server, as part of an embedded or external Platform Services Controller (PSC), does not correctly implement access controls.

Reading Time: 5 minutes The VMware ESXi partitions layout on the system disk has remained almost the same for several years. VMware ESXi 6.x partitions layout was the same from previous 5.x versions and there ware only some exceptions with bigger disks (with two different diagnostic partitions. Starting with ESXi 7.0 the partions layout is now totally changed.

Reading Time: 3 minutes Some days ago, VMware has updated its per-socket pricing model effective from April 2, 2020. Instead of require only one license per socket (so per physical CPU), in the new model, one license will cover up to 32 cores… with more cores you need more licenses (one each 32 cores).

Reading Time: 2 minutes A usual way to backup the VMware vCenter Server Appliance (VCSA) is to manage as a common VM and use a backup solution to backup (and restore) the entire VM. But it’s approach does not always work and cannot guarantee a restore in some cases, for example in the case of a database corruption.

Reading Time: < 1 minute Universal Serial Bus (USB) is an industry-standard that establishes specifications for cables and connectors and protocols for connection, communication, also and power supply between computers, peripheral devices and other computers.

Reading Time: 2 minutes Changed Block Tracking (CBT) is a VMware feature introduced in vSphere 4.0 in order to implement native incremental backup at source level. VMware VDAP uses this technology and so all backup and recovery software designed for VMware use it for speed the backup. This mean that all the backup products that are using VDAP, will rely on VMware API and features, … and bugs.

Reading Time: 5 minutes VMware vSAN 6.7U3 it’s out and maybe you would like to upgrade your environment. But note that there are some possible performance issue with vSphere 6.7U3 on Dell servers. 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: 3 minutes Six month ago there were only few VMware vSphere 6.7 books, but fortunately now there is a better offer with also some good and valuable resources. I’ve already wrote about the new edition of Mastering VMware vSphere 6.7, now I would like to write some comments about the VMware vSphere 6.7 Data Center Design Cookbook – Third Edition book released on March 2019 and written by Mike Brown and Hersey Cartwright.

Reading Time: 6 minutes The new VMware vSphere 6.7 Update 2 has been announced some weeks ago, but was not yet available (although lot of people have already wrote about most of its features)… now finally VMware vSphere 6.7 Update 2 is general available (GA) and you can download the bits and really test all its features This is a huge step and called just an update release is too limiting… there are so much difference with the VMware vSphere 6.7 Update 1 (released on October 2018) to make it much more like as a 6.8 version.

Reading Time: 3 minutes VMware vSphere Update Manager (VUM) enables centralized, automated patch and version management for VMware vSphere and offers support for VMware ESXi hosts, virtual machines, and virtual appliances. For ESXi hosts it can manage both the update and the upgrade workflows, but can also be powerful for adding custom VIB package, like for example new drivers. Usually it takes the updated files from the VMware repository, but you can also add custom repositories (or depots).
