I have an old HP server TC4100 with Netraid 1M SCSI controller
I want to change my old DAT 24x6 Surestore with a Ultrium 448 device
Is it possible to connect External Ultrium 448 with Netraid 1M controller ?
Thank you
Corrado

SolutionTape drives are not compatible or reliable with raid. Raid is single ended, and does not communicate with differential devices.
For best reliable back ups use a PCI HBA and avoid RAID.
Typically what you can see is detection issues on POST or in the OS and intermittent problems with CRC and IO issues. It can also cause the drive to turn on the cleaning light for no apparent reason and cause the drive to start rejecting media tapes.
Many manufacturer's won;t even bother to troubleshoot or offer assistance for tape devices connected with RAID cards.

Re: Ultrium 448 and NetRAID 1M
I have another question ...
I think that now my DAT 24x6 surestore is connected to this controller and it's working...
Am I wrong ? maybe I need to open this server and check better ?
Thank you

Re: Ultrium 448 and NetRAID 1M
I found (Google) that it's LSI53C1010
PCI to dual-channel Ultra160 SCSI controller
Maybe 24x6 surestore is connected to this and not to netraid...
The question is the same: can I connect an Ultrium 448 ?
Thank you

Re: Ultrium 448 and NetRAID 1M
The LTO 448 specs are; 160 mb/s burst rate, 24mb/s native throughput (48mb/s compressed)
The LTO 448 is well suited to an Ultra 160 HBS (non-raid) controller.
Review these links for HBA's:
HP recommended HBAs (see the section 3/4 of the way down the page)
