Mine are HP drives installed in a HP MSL6000 library (aka NEO4000) > Do you achieve these rates on a SunFire 280R? No, Wintel hardware (HP Proliant DL580g2 - old tech now) > What is your scsi card? HP badged Qlogic Fibre HBAs (2Gb/s, but 4Gb/s is available now) > I usually never achieve more than 8-10MB/s.......how can it be?! What do Certance quote as maximum throughput on the drives? Typical problems are: 1: Slow scsi speeds 2: bad termination 3: Long cables 4: Scsi contention The drives here go through a fibre-scsi router on the library, which has a dedicated U320 bus per drive. Newer (LTO3) drives are direct fibre attached and even faster.... AB ------------------------------------------------------------------------- Using Tomcat but need to do more?
