How many paths to SAN switch? How many host adapators on the STK? How many ranks are the SCSI disks split over? The HA is the real limiting factor here. A maxed out ESS (i.e. all possible CHPIDs & HA in use to disks split) is a capable of 250 MB/s (read) and about half that for write.
-----Original Message----- We have 8 paths to each chpid on the mainframe dasd. And I/O subsytem. SAN is network and is fiber. I had wondered if the paths had helped swing the stats. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
