Hitachi 9000 (was RE: 2GB or not 2GB )

Kevin,

Can you elaborate on this or point me to a source? I am working for a
large company that uses Hitachi SANs and we are getting HORRIBLE
performance for a data warehouse (i.e. 15 minutes to scan a 100 MB table).

The server people and SAN people are both in separate organizations and we
do not have much information, other than what they provide. They tell us
that "all is well".

Any help would be appreciated.

Keith
