What is really bad is that all the people who design the SAN systems always want to consolidate down to a single large 20 or 30 TB system in order to save costs - and never plan for the week long rebuilds!
RAID's original meaning is still true. It would be better to have 15 SANs of 2 TB each than a single 30 TB one even with the cost of extra hardware - you now have no single point of failure and alternate plans and methods of recovery if one goes down. 5000 people unable to work for one week is $5 Million - vs cost of extra hardware - which really will cost more?
