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 […]
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 […]
Reading Time: 4 minutes Objective 3.3 – Create and Configure VMFS and NFS Datastores See also those similar posts: Objective 3.3 – Create and Configure VMFS and NFS Datastores and Objective 3.3 – Create and Configure VMFS and NFS Datastores. 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 […]

Reading Time: 2 minutes Objective 2.2 – Configure vNetwork Distributed Switches See also this similar post: Objective 2.2 – Configure vNetwork Distributed Switches and Objective 2.2 – Configure vNetwork Distributed Switches Identify vNetwork Distributed Switch capabilities (similar as vSphere 4.1) Official page with features of vDS: Improves visibility into virtual machine traffic through Netflow (New in vDS 5) Enhances monitoring and troubleshooting using SPAN and LLDP (New in vDS 5) Enables the new Network I/O Control (NIOC) feature (now utilizing per VM controls) (New in vDS 5) Simplified provisioning and administration of virtual networking across many hosts and clusters through […]
Reading Time: 3 minutes vStorage API Introduced for the first time in vSphere the vStorage API are specific functions to permit an integration more thight with external storage functions. Note that there also other integration module that are coverd in the PSA framework. For more information see: What Is New in VMware vSphere™ 4: Storage What’s New in VMware vSphere™ 5.0 – Storage vSphere Storage API – Storage Awareness (VASA) This is a new set of APIs introduced in vSphere 5.0 that will enable VMware vCenter Server to detect the capabilities of the storage array LUNs/datastores, making it much easier […]
