No, they both can use either the J (standard) or K (extended length) type tapes.

Data transfer from the host to the 3590 controller. SCSI, depends on length and type of connection (34 was the top on SCSI E1A). 40 MB/sec on FC E1A advertised, but I have seen higher (FC) 70 MB/sec on FC H1A advertised (FC) Then, compression voodoo happens so less physical bytes are written to tape. Data transfer from the 3590 controller to the tape (referred to as "at the head"). 9 MB/sec on B models 14.1 MB/Sec on E models Paul D.

I believe throughput of 15MB/SEC applies to all 3590 drives thus far. John G. Talafous IS Technical Principal The Timken Company Global Software Support P.O.

This past year I have had IBM out at LEAST 2 dozen times working on my drives!!! The worst part is they bring used parts. They have had to go back & pickup the same part again because the replacement parts have been BAD a bunch of times!! I have seen posts about H1A drives. What is the difference? --------------------------------------- Bruce Kamp Midrange Systems Analyst II Memorial Healthcare System E: [EMAIL PROTECTED] P: (954) 987-2020 x4597 F: (954) 985-1404 --------------------------------------- -----Original Message----- From: Talafous, John G.

Do you have a maintenance agreement and have you called support when you are experiencing problems? You should! We have a 3494 library with 6 3590-E1A drives in it. These drives are work-horses. We have had two service calls this year. But, you must remember we are backing up 2700+ nodes, are using 700+ extended length cartridges and keep those drives moving data around the clock. As for performance, I have seen transfer rates of 70GB an hour. This is on tape to tape copies of storage pools (You won't see that when migrating disk to tape.). The bottom line is that the 3590 is industrial strength! But, I must admit having no experience with the B drive. John G.

As we are having lots of hardware problems with these drives we think about changing them to 3590 drives type E. Does anyone have experience with this type of tape drive ? I`m mainly interested in a kind of comparison concerning performance and availibility between the both types B -> E.
