Welcome to our community

Can you answer this question which everyone else seems to think impossible.

A customer of mine has an Alpha Server 8400 (GS140), they are struggling with backups and want to attach an MSL6030 LVD/SE

Do you know of a card that the GS140 will support and that will interface the MSL6030.




Thanks and Regards,

Hi Richard,

Take a look here for GS140 supported options.....

regards,

Thanks for the supported options list.
The descriptions in the list are slightly wrong, it reads:
PCI-based one port Ultra SCSI
Single-ended how adapter KZPBA-CA
PCI-based one port Ultra SCSI
Single-ended how adapter KZPBA-CB

Also, I'm not sure what Single ended how adapter means? I think it should read as

Thanks

I think the supported adapter list has a mistake on it, it reads:
PCI-based one port Ultra SCSI Single-ended how adapter KZPBA-CA
PCI-based one port Ultra SCSI Single-ended how adapter KZPBA-CB

I think it should read:
PCI-based one port Ultra SCSI Single-ended how adapter KZPBA-CA
PCI-based one port Ultra SCS

The MSL6030 is probably not a good match for this box - Depending which flavour of Ultrium tape drive is installed. Ultrium 1 will require a SCSI bandwidth of something like 30MB/sec (ballpark figures!) - Ultrium 2 about 60MB/sec, and Ultrium 3 about 160 MB/sec. The fastest adapter in the supported options list is ULTRA SCSI at 40MB/sec. MSL6030 will typically be at least Ultrium 2 drives.

You'll probably find the library won't stream data too well, resulting in "shoeshining" (excessive positioning operations) - which means rubbish performance, and potentially excessive wear on tape heads & media..........not a good scenario !.

Might be better in the long run to back up to an intermediate disk, maybe over a network - then use a faster server/SCSI subsystem, to back up to tape. Either that, or (crazy as it may sound!) use a 'slower' tape library.
