*** Storage Configuration
Users' mail stores are distributed across 32 partitions.
Each user's mail is on one partition.
Each partition is 300 GB of RAID1 drive pairs.
There are 8 pairs on each of four Promise Vtrak E610fD SAS arrays.
A RAID0 volume for spool and logs is on a fifth Promise SAS array.
All five arrays connect to the SUT through two Qlogic 5600 fibre channel switches
and one LSI 7404EP FC HBA PCIe card.
*** Power Configuration
SUT, FC switches, and external disk arrays all have dual hot-swappable
power supplies powered by external UPS.
