Ben, It's highly recommended that (on Solaris) you use raw volumes for the TSM file systems (ie, db & log)... due to severe performance penalties. Other than that, all should be okay. There are other rules of thumb to consider, especially on Sun boxes, regarding how much CPU power to support multiple NIC's of varying speeds and bandwidth, as well as number of SCSI drives/ports, etc. (search the archive for recent info about sizing the server).
