Hi -
For the past few days I have problems with some sas controllers.  On begin I will describe what I would like to accomplish. I have few tapes with large block size (over 64k) and I would like to duplicate these tapes but for some reason my destination drive won't write the data with the specified block sizes. I tried to  resolve this problem by eliminating the drives and other issuse (I doing this under the linux that this is not problem with windows (some version) limitation. I think that  I need a sas good or compatible controller.
Already I try to adaptec model - the same issue - I found out that adaptec is not good for the sas as was good for scsi. Right now I am looking to buy some which will work for me with large block size. I hope that somebody from you had the same problem before and found solution. I will be very thankful for any advice.

Regards, selsta

So long as it doesn't do RAID or RAID can be disabled most SAS controllers are OK, maybe you can get recommendation from the tape drive maker, what drive is it?

Hi -

This is LTO4 HH (Quantum SuperLoader 3, one LTO-4HH tape drive, 16 slots, SAS).
Finally today I make them work. I use the LSI LOGIC 3442E-HP, installed and tested under CentOS 5.3 (is not driver for newer version of Linux). No longer problem with large bocks size (> then 64kb).
Thank you for this "RAID" info. I will be careful when I will buy my next SAS cart for tape drive connection.
