Adaptec host adapter AHA-2940 Ultra - Connect removable, back-up storage devices in desktop and server environments
The AHA-2940 Ultra host adapter is the ideal PCI-to-SCSI host adapter for entry-level servers and workstations. It moves data fast -- up to 20 MByte/sec. And it connects up to 7 SCSI devices for expanded storage capacity. In addition, the AHA-2940 Ultra adapter delivers unrivaled system and peripheral compatibility.
The AHA-2940 is the newest addition to the Adaptec line of RISC-based SCSI host adapters. At the core of this new host adapter family is the Adaptec-designed PhaseEngine RISC processor. The 10 MIPS PhaseEngine processor minimizes the time it takes to process SCSI commands by automating SCSI phase changes and advanced SCSI features. This allows the CPU to perform other tasks and improves overall system efficiency and performance.
The programmable PhaseEngine RISC processor also executes self-contained microcode, which is downloaded by the main CPU at system initialization. This enables quick and easy microcode upgrades. Further, a 64-byte scratch memory stores configuration information established by the BIOS-resident SCSISelect configuration utility.
With the Adaptec-designed RISC processor, the AHA-2940 host adapter maximizes system I/O performance by utilizing the PCI local-bus to process data at transfer rates of up to 133 Mbytes/second. This new technology is essential in meeting the demands of high-performance applications.
