Description
The Adaptec AHA-2950U2B is a high-performance RAID controller designed for servers and workstations requiring robust SCSI storage management. It utilizes the Ultra2 SCSI interface, offering a significant bandwidth of up to 80MB/s per channel, which was a substantial improvement for its time. This controller card features a 64-bit PCI interface, enabling it to take full advantage of the higher bandwidth offered by 64-bit PCI slots found in many servers. This combination of Ultra2 SCSI and 64-bit PCI provides a powerful platform for connecting and managing multiple SCSI hard drives. The card typically includes onboard cache memory (often 4MB or 8MB) to buffer data transfers, further enhancing performance and reducing latency. The RAID capabilities of the AHA-2950U2B allow for the creation of redundant and high-performance disk arrays. It supports common RAID levels such as RAID 0 (striping for performance), RAID 1 (mirroring for data redundancy), RAID 5 (striping with parity for a balance of performance and redundancy), and RAID 10 (striped mirrors for high performance and redundancy). This makes it a versatile solution for applications demanding data integrity and speed.
