Explanation:
Use 4-12 volumes, which equals 10 to 30 VMs per datastore as Dell best practices.
Note: Datastore size and queue depth
While administrators continually try to maintain an optimized data layout and performance, the size of the Datastore becomes a question. Because every environment is different, there is no hard-set number.
However, you will find recommendations of 10-30 VMs per Datastore. A number of factors in this decision include speed of the disks, RAID type and intensity of the VMs.
