Plain Virtualization

Decide to start a new chain of post on articles and reference done by various expert that I refer to and read about which might be good to take note of. I will be updating this post as often as possible and updating the date so it will be the first post whenever I update it. For those who are into know more on planning for DRS and Availability I would strongly encourage that you read about the VMware vSphere 5 Clustering technical deepdive. Storage DRS Have datastore clean formatted as VMFS 5 datastores.  This does not just helps but it will also put the load when perform any storage activities like Storage DRS, Storage vMotion to the storage subsystem if VAAI is supported.  Having upgrade the datastore from VMFS 3, would still result in sub-block sizes especially if there are not formatted using 1MB blocksize which is standardize in vSphere 5.  In such, the lod legacy datamover (FSDM) will be use which slow down such activities and making benefits from Storage ...

I was doing my VCP5 studies and was reading the Installation and Setup Guide and came across the below on Page 62. The boot process proceeds as follows. 1 The administrator reboots the host. 2 As the host boots up, Auto Deploy provisions the host with its image and host profile, which are stored in vCenter Server. 3 Virtual machines are brought up or migrated to the host based on the settings of the host. n Standalone host. Virtual machines are powered on according to autostart rules defined on the host. n DRS cluster host. Virtual machines that were successfully migrated to other hosts stay there. Virtual machines for which no host had enough resources are registered to the rebooted host. If the vCenter Server system is unavailable, the host contacts the Auto Deploy server for image profiles and host profiles and the host reboots. However, Auto Deploy cannot set up vSphere distributed switches if vCenter Server is unavailable, and virtual machines are assigned to hosts only if they ...
