Thanks for the replies!
I knew about the single read... I just hadn't thought about it in this
context yet.
So how are people configuring their AFDs? 1 big physical LUN and lots
of AFDs configured on withing directories of that LUN, or actually
configuring lots of small LUNs? BTW... do the read devices of AFDs
count as a part of the 32 allowed devices in power edition?
Thanks,
Joel

Joel,
I'll second Itzik's comments about the one read limitation and
smaller AFDs may be the answer but you must bear in mind the total
number of devices (device count tends to rocket when you have SAN
attached devices that are shared).
Not a showstopper but just something to be aware of.
Regards
Bob

Hi Joel,
The AFD has a big limitation - only one read from it.
Thus if all your backups will go to AFD, and you will have one client in
each group, the cloning processes will queue up waiting for read access
to the AFD. In such cases it is advisable to define many smaller AFD
than just one large one. Itzik

Hey All,
I'm getting a bunch of ATA disk this year that I plan on
using as AFDs.
One of my biggest pain spots is cloning. We clone everything from
everyday. I am considering changing my group setup from what I have
now, around 30 big groups, to 1 group for each client so that I can
utilize automatic cloning and the random accessibility of
AFDs. So that
said... my questions are below...
BTW V880/Solaris 9
Is anyone doing this now in a medium sized environment(300 clients) or
have you and it didn't work well?
Are there any known limits to the number of groups... or number of
savegrp commands that can be running at once?
This is just kind of an earlier thinking process on this, so
if you have
better suggestions for utilization AFDs I would love to hear them.
Thanks,
Joel
