Reading Time: 3 minutes DellEMC PowerStore is the new product line that will replace the old Equallogic/SC/VNX/Unity series. It’s a nice product with a mix of the features of all those prevuious products and a new modern design both in the hardware and the software parts. From VMware vSphere point of view it can be access as a block level storage with iSCSI and/or FC protocols, but it has also a native vVols implementation and, for example, in the PowerStoreX model it’s the default way to access at the storage resources.

Reading Time: 2 minutes The file-level backup feature introduced in vCSA 6.5 is very powerfull and schedulable (starting with vCSA 6.7) because sometimes the image-level backup may not provide the proper integrity if you have corrupted files inside the VM. Also with vSphere 7.0 is possible monitoring the status of the file-level backup directly from vSphere Client and this is quite usefull to have this information direct visible from the UI:

Reading Time: 2 minutes The VCSA update procedure is usually easy and simple and can be performed from the VAMI as explained in a previous post: Manage VCSA updates with VAMI. But sometimes may failed for different reasons.

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: 18 minutes Intel® Optane™ Technology for Data Centers are a revolutionary solutions to bridge critical gaps in the storage and memory hierarchy delivering persistent memory, large memory pools, fast caching and fast storage. Basically there are two main Intel® Optane™ DC products: Intel® Optane™ DC persistent memory  Intel® Optane™ DC SSDs

Reading Time: 3 minutes One interesting news of the latest version of vCSA is the health monitoring feature. You can check the overlall health with your vSphere Client, by selecting the vCenter node and then Monitor | Health.

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. How USB is supported in VMware vSphere?

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 […]
