Pierre, Do you mean Lan-free backups? Look at: the Redbook: "Getting more out of your SAN with TSM"
From what I read it appears many sites will try to implement Lan-free if
they have an environment that supports it, but depending on the specifics, there may be no performance advantage but there will be a lot of configuration and sys admin maintanance overhead. Are you backing up large databases or files on those NT boxes?
From the Redbook:
SAN-based (or LAN-free) backup performance will decrease when many smaller objects are transferred, because more time is spent in non-SAN communications. In some cases, a LAN-based backup might even be faster than a SAN-based one for the same workload. Most typically, using LAN-free for backing up larger objects, such as database files or full volume image backups, yields the best performance. Traditional Tivoli Storage Manager progressive incremental backups usually perform better over the LAN than LAN-free, because this type of backup typically does not exploit fully the speed of the SAN or allow a tape drive to operate at streaming speeds. LAN-free to disk backup might also be appropriate for these type of environments. ----- Original Message ----- From: "CAYE PIERRE" <[EMAIL PROTECTED]> To: <[email protected]> Sent: Tuesday, October 02, 2007 8:01 AM Subject: [ADSM-L] SANERGY Hi, I am looking for feedback about use of SANergy. Looking for impressions, efficiency, applicable domains, problematics, difficulties and so. I am studying possible implementation of SANergy for backup purpose in wintel world (with AIX/TSM Server).
