Hello
We are upgrading to new md38xx series
Our goal is: maximum performance for virtual machines, low cost, stable redundancy, 10tb storage spade.
We are now split between two choices:
Md3800f 12x 2tb nlsas 7200 drives - raid 10 disk group
Or
Md3820f 24x 900gb 10k drives - DDP
Storage will be almost same for both configurations
But how will performance compare between both solutions?
Ddp is based on raid5/6 so the question if it can compete with the fast raid 10 on first configuration
Will it be worth to invest extra $ to get the 24 ddp group?
