Ultra320 SCSI Controller for PCI-X Servers
The IBM 13N2249 is a 64-bit/133MHz PCI-X host adapter that delivers Ultra320 SCSI connectivity. It targets administrators maintaining legacy IBM eServer xSeries or IntelliStation systems that require direct-attached SCSI storage. The card ships with a low-profile bracket suited for 2U rackmount chassis.
Passive Cooling and Single-Slot Power Draw
As a plug-in card without onboard RAID logic or active cooling, it relies on chassis airflow and draws power solely from the PCI-X slot. The absence of a RAID processor keeps thermal output low and eliminates fan noise, making it a quiet addition to existing server configurations.
One Internal and One VHDCI External Port
The adapter provides two SCSI ports: one internal connector and one external VHDCI port, enabling mixed internal and external device chains. It occupies a single low-profile PCI-X slot and requires no additional cabling brackets, freeing adjacent slots for other expansion cards in dense 2U deployments.

Questions about this item
How do I install the low-profile bracket on a 2U server and which PCI-X slot speed is required?
Fit the supplied low-profile bracket, insert the card into a 64-bit 133 MHz PCI-X slot, connect the internal SCSI device to the onboard port and attach the external VHDCI cable to the second port.
Which components on this controller are most likely to need replacement after extended operation?
The onboard SCSI connectors and the PCI-X edge connector are the primary wear points; the card has no RAID battery or fan, so those items never require service.
What throughput ceiling appears first when the controller runs at sustained load?
The Ultra320 SCSI interface caps sustained throughput at 320 MB/s, and the single 64-bit 133 MHz PCI-X host bus provides the same peak bandwidth.
