work is implementing Exchange Server 2k3 and we're putting together a hardware list for installation. there are nearly as many theories in setting this up as there are books to describe them. One system we're going with is a clustered server back end to handle the database.
This arrangement has a shared scsi storage system.
I'd like to know how this works, on a scsi level.
I thought that a scsi bus had one controller and many slave devices. How does the control function work with two controllers?
