Replacing 48 Drives with just 5 and still 45TB of Storage - 1053

I have two NetApp D4243 disk shelves, a total of 48 drives. They are at the moment populated with 20x 600GB SAS drives and 24x 1TB SATA drives,,, that is pretty much a vast of power if the system is in 24/7 operation,, so we have a bit of a chat about that.
Shameless self-promotion of my own shop: www.myplayhous...
