Adaptec ASC-39320A Ultra320 SCSI controller

This Adaptec ASC-39320A is a dual-channel Ultra320 SCSI controller card designed for PCI-X slots. It targets system builders and IT professionals maintaining legacy enterprise storage arrays or tape libraries that require wide SCSI connectivity. The card provides two independent channels for connecting multiple devices simultaneously. It serves a specific niche where older SCSI infrastructure must remain operational.

Dual-channel Ultra320 performance and headroom

Each channel delivers up to 320 MB/s bandwidth, allowing high-throughput access to compatible Ultra320 drives or enclosures. The dual-channel design lets administrators segregate workloads, such as separating backup targets from live data volumes, without contention. Performance scales with the slowest device on the bus, so mixing slower legacy drives will limit overall throughput. The PCI-X interface requires a matching slot; standard 32-bit PCI slots cannot accommodate this card.
