Not directly about the mainframe, but our DASD is usually RAID on the back end.
Interesting article on how the increase in the size of individual drives in a RAID array are actually making it less reliable. This is due to the fact that the amount of I/O done to rebuild an array can cause another hard I/O error, which will destroy the RAID array entirely (RAID-5 with a single parity drive). http://www.enterprisestorageforum.com/technology/features/article.php/3839636 -- John McKown Systems Engineer IV IT Administrative Services Group HealthMarkets(r) 9151 Boulevard 26 * N.
