Hi All,=20

Thank you all for the responses.=20

Our present PCI bus is 33 MHz.When you say that the 2 Gb/s HBA will =
improve throughput, are you implying that a 66 MHz PCI bus would be =
needed? The application is tape to tape copies. I'm trying to estimate =
how many STK 9840B drive pairs can be driven concurrently at full-speed =
or near full-speed with a 4-processor SunFire 4800 in both cases (Case1: =
33 Mhz PCI, 1 Gb/s Qlogic 2200 HBA;Case2: 66 MHz PCI,2 Gb/s Qlogic 2200 =
HBA).
