Description
Features: AHA-2940 Ultra- Bulk Pack of 10
PCI Ultra SCSI controller for desktop PCs and servers.
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.
Includes 10 cards and one CD.
- At the core of this host adapter family is the Adaptec-designed Phase- Engine 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 taks 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.
- The AHA-2940 family of host adapters is easily installed and configured. Simply install the board in the PCI slot, then run the menu-driven SCSISelect configuration utility resident on the host adapter. The SCSISelect configuration utility eliminates the need to handle jumpers, making host adapter installation quick and easy. In addition, the programmable active termination featured in the AHA-2940 family and controlled by the SCSISelect utility makes installation of external SCSI peripherals fast and simple. When upgrading the PCI system with external SCSI peripherals, there is no need to open the PC chassis. Adaptec's SCSISelect utility provides key information on-screen, including the host adapter version and current configuration. Active termination and other host adapter settings may then be reconfigured on-screen through menus rather than handling jumpers and changing switch settings on the hardware.
