Hello,

     We have been running the TSM Server on z/OS, backing up 
Windows/Solaris/Linux clients. Our backup media has been a StorageTek 
Powderhorn Tape Silo, emulating IBM 3490E drives (tape capacity 2GB). Within 
the year the silo will be upgraded to emulate IBM 3590 drives (tape capacity 
60GB). 

     Clients have been dissatisfied with the throughput of the TSM backups. 
Typically, the aggregate transfer rates have ranged between 1MB and 3MB/sec. 
That's not good when you want, for example, to backup an Exchange database over 
100GB in size.

     Anyway, there is a project spawning here to possibly bring in some SAN 
boxes, like the EMC Clarion models. The idea would be to somehow directly 
backup to the SANs, or have a tape silo Fibre Channel connected directly to the 
SAN. 

     My first question is, is there a way for the TSM Server on z/OS to talk 
directly to the SAN boxes? Or would the SAN have to be emulated to z/OS to look 
like some type of IBM mainframe tape device (3480/3490/3590/whatever)?
