New in vSphere 5 – VMware HA advanced options

30 September 2011
Comments off

Reading Time: 2 minutes With the new HA implemenation, something has changed also in the advanced options with new parameters, but also with some that now are no more available. For a list see Supported vSphere 5.0 Advanced Options. One options that has been removed “das.failuredetectiontime”. The reason is well explained in Duncan’s HA Deep Dive: I know many of you used this advanced setting to tweak when the host would trigger the isolation response, that is no longer possible and needed to be honest. If you’ve closely read my other articles you hopefully picked up on the datastore […]

Reading Time: 3 minutes For a list of all objectives see the VCP5 page. Objective 5.5 – Backup and Restore Virtual Machines See also: Objective 5.5 – Backup and Restore Virtual Machines and Objective 5.5 – Backup and Restore Virtual Machines. Identify snapshot requirements (similar as vSphere 4.x) See the vSphere Virtual Machine Administration Guide (page 208) and VMware KB: Understanding virtual machine snapshots in VMware. Note that snapshots provide a point-in-time image of the disk that backup solutions can use, but Snapshots are not meant to be a robust method of backup and recovery. If the files containing a […]

Reading Time: 9 minutes Note This product has been discountined with the release 5.1 and replaced by the new VDP. Disclaimer I do not work for VMware and I’m not writing that VDR is the best backup product! First versions were affected by some bugs and issues… But now (from 1.2 release) could be one possible backup solution (of course with its limits). VMware Data Recovery (VDR) Official VMware site: http://www.vmware.com/products/data-recovery/ See also: http://communities.vmware.com/docs/DOC-11443 For VDR2 see also: Things to know before implementing VMware Data Recovery (vDR) 2.0 Note that this product works quite like the old esXpress (similar […]

Virtual CPU and Virtual Cores

22 August 2011
Comments off

Reading Time: 2 minutes In a physical environment usually the term CPU is used to refer to the physical package (or socket). The real processing unit inside this package are called cores (and not that each core can have inside more ALU and can be seen as more logical cores with hyper-threading feature). More CPU usually define a SMP system, more cores a multi-core CPU, more CPU each with more cores a complex system (usually the NUMA architecture is used in this case). In a virtual enviroment the term vCPU is used to refer to a core assigned to […]

Identify VMFS and NFS Datastore properties (similar as vSphere 4.x) See the vSphere Storage Guide (page 21). NFS as quite the same functions (also hardware acceleration introducted in vSphere 5), but still cannot implement a RDM disk, and for this reason cannot implement a guest cluster solution (like Microsoft MSCS). Identify VMFS5 capabilities (new in vSphere 5) See the vSphere […]
