You tape drive is most likely a SCSI HVD. Attaching to the 5702 with a interposer will not give you much of a performance gain. Changing the interface on your tape library to Ultra SCSI LVD, if possible, will give you a small performance gain. See IBM's comparison of different tape devices for max transfer rates base on different connections and adapters. If you library can have the drive(s) replace with LTO drive(s) you will get the most performance gain but have to replace your tapes. Either way, cheap means very little performance gains but remain you investment. If you have the open port and can upgrade the SCSI interface on the library, go that route. Christopher Bipes

Subject: Attaching a 3995 library to a model 520



Hi *all,

we switched from a model 810 to a new 520 system and want
to use the (newer) SCSI controller 5702 instead of the 2749.
The second port of our 5702 is free, we wonder about the type
of cable you need to go to the 3995-C40, if it is possible at all ?
Maybe an interposer is needed ... ?

Thanks for any help,
Philipp

Chris, thank you for your tips,

I simply need that PCI slot the 2749 controller is occupying, performance is
not an issue. The 3995 is an optical library and was available with different
interfaces. Maybe we can do an upgrade to another interface type.

Thanks again,
Philipp
