Hi Bill,
I got 4 LUNs from our SAN-People. One sized 105GB the other three sized
35GB.
The vpath (hdisk) from the big LUN:
PP SIZE: 64 megabyte(s)
TOTAL PPs: 1567 (100288 megabytes)
The vpath from one of the small LUNs:
PP SIZE: 64 megabyte(s)
TOTAL PPs: 521 (33344 megabytes)
3x521=1563 PPs => I "loose" only 4 PPs ...
HTH a little

Hi *,
I am going into a meeting with our SAN team in about 45 minutes. I've been
pouring over Redbooks all morning to try to find information on something.
Hopefully the synergy out there will help.
Is there any best practice of documentation out there that says anything
like:
When carving a LUN in the ESS, using fewer BIGGER LUNs is more
efficient than more SMALLER LUNs.
I can see where AIX would have more overhead, but is it worth it ?
Thanks, Bill.
