PROS: Really really big LUN sizes ( much larger than 3390-9 or -27 ) LUNs appear as regular scsi volumes eg: /dev/sda LUNs can reside on basically any SAN storage on the network, can use much cheaper disk than traditional ECKD type
CONS: Multipath is not trivial to implement over FCP, it comes free with FICON can't use HSM or other zOS based tools to manage physical volume backup and restore Performance Analysis tools for SAN are not as mature as those for FICON FCP does less error checking than FICON, so data integrity errors are slightly more probable On 9/22/05, Robert Johnston <[EMAIL PROTECTED]> wrote: > > Good Afternoon..
