Adaptec AHA-2940I PCI SCSI Controller

The Adaptec AHA-2940I is a PCI SCSI controller card designed to add SCSI connectivity to servers or workstations. It suits administrators maintaining legacy storage arrays or tape libraries that still rely on the parallel SCSI bus. The card installs into a standard PCI slot and carries the Adaptec brand.

Compatibility and Alternatives

This card fits systems with an available PCI slot and a need for traditional SCSI device support. Builders requiring newer serial-attached interfaces or higher throughput should consider other options. Users without PCI slots or SCSI peripherals will not be able to use this controller.

2940 Model Identifier

The model number 2940 identifies this specific Adaptec controller within the product line. It distinguishes the card from other Adaptec SCSI or RAID adapters that use different interfaces or feature sets. Verify the 2940 designation against your hardware list before ordering.

Questions about this item

Does the 2940 controller use a standard PCI interface, and what throughput does that bus cap at?

The card uses a PCI interface; practical throughput is limited by the bus clock and width of the host system.

What physical slot and bracket does the 2940 need to mount in a server chassis?

It requires a 5 V PCI expansion slot and a standard full-height bracket for installation.

How is the 2940 installed, and which step is most often missed?

Insert the card firmly into the PCI slot, secure the bracket screw, attach the SCSI cable to the onboard connector, then run the BIOS configuration utility to initialise the array before loading the OS.
