so first i create the raid group raid 5 7+1.
the raid group is connected to sp or the volumes or luns i am creating?
Your RAID Group / LUNS Should be connected to Both Storage Processor via Zoning.
then how many luns can i create as best practice for vms.is it good 2 luns and then i i have in each lun(datastore) 8-10 vms.
or one lun with all vms there.?
Its totally depend on your requirement. How much VMDK size you are allocating to VM Guets ? is there any additonal disk you are adding to VM Guests ? 1 or 2 TB is enough for 8 to 10 VMS.
Thanks
