Hi Daniel!
The SAN Data Gateway uses High Voltage Differential SCSI interfaces by
default. If your are using the default SCSI interfaces, your drives will
probably be also HVD drives. They perform considerably less then the Low
Voltage Differential drives. The specs on the IBM pages (sustained data
transfer rate 15MB/sec native) are LVD transfer rates. You will never
achieve this with HVD SCSI. However, 2.5 MB/sec is very slow. What's the
SAN Data Gateway's microcode level? Kindest regards, Eric van Loon KLM
