The only downside to not multiplexing is the number of drives you have to create and configure as well as the number of virtual media you have to create as well. Depending on the VTL, media can be created by allocating all the virtual cart space up front of allocating space on demand. So, if you VTL only allows you to create virtual media by using the space up front, you'll be limited in # of tapes by capacity, which might not be enough to mount into all of the virtual drives required for each stream.
Other than that situation any MPX setting from 1-32 should work.. -Trey -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Travis Kelley Sent: Wednesday, April 30, 2008 1:41 PM To: veritas-bu@mailman.eng.auburn.edu Subject: [Veritas-bu] Multiplexing on VTL's We recently purchased a VTL to backup some short retention backups to. The backups will expire on the VTL and will not be duplicated to tape or anywhere else for that matter. We also have capacity licensing so we can create as many virtual tape drives as necessary. I don't believe multiplexing is necessary in a situation like this and that we would be better off configuring enough tape drives to handle the number of streams we need and turn multiplexing off. Does anyone know of any reason this logic would be flawed...and if not is there any documentation out there to support that multiplexing is not a good idea when using VTL's? _______________________________________________ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu _______________________________________________ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu
