Re: Minimun number of disk in a diskgroup - Eva 8400
The minimum number 'recommended' depends on the required disk capacity and how many I/Os the EVA needs to deliver for your servers.

Re: Minimun number of disk in a diskgroup - Eva 8400
8 disks is the minimum for FATA and FC drives to form a new disk group. You can add more in if you wish at the time of creation or just add them in later. Recommended to add in in multiples of 8 but it can be any number.
6 is the MIN for SSD with a MAX of 8 for SSD.
You can only have 8 SSD max in any EVA that supports them.
All drives in a disk group must be the same typa of drive as in ALL FATA or ALL FC but you can mix the different speeds / capacities but it is generally not recommended to do this for several reasons.
Max number of disks per disk group = all the disks of a given type in the array.
Min disk groups for ALL EVA is 1.
Max depends on EVA but for an 8400 it is 16.

Re: Minimun number of disk in a diskgroup - Eva 8400
Single protection reserves twice the size of the largest disk in the disk group.
Double protection reserves four times the size of the largest disk.
