My company experienced some performance problems so I created a new storage design in which was decided there should be a maximum of 4 VMs per datastore. That means a lot more creating and adjusting datastores, but limiting the number of VMs per datastore increases the number of SCSI commands to the datastore per VM which increases the reaction time of storage related events. This article shows you how to create a new datastore which is done by doing the following steps:
- Checking for availability of space
- Resizing the volume where the datastore will reside
- Creating a LUN and mapping this to the ESX Cluster
- Creating the datastore
- Setting MPIO optimal settings
