Product Description
The Adaptec ASR-2120S is a high-performance RAID controller card that leverages the Ultra320 SCSI interface, offering robust data storage capabilities for servers and workstations. Ultra320 SCSI provides a maximum theoretical throughput of 320MB/s, making it suitable for demanding I/O operations. This controller is designed to manage multiple SCSI drives, enabling the creation of RAID arrays for enhanced data redundancy and performance. Equipped with 64MB of onboard cache memory, the ASR-2120S accelerates read and write operations by buffering data, which helps to reduce latency and improve overall system responsiveness. It supports a comprehensive suite of RAID levels, including RAID 0 for maximum performance, RAID 1 for mirroring, RAID 5 for parity-based redundancy, RAID 6 for dual-parity protection, and RAID 10 for a combination of striping and mirroring. This flexibility allows administrators to configure storage solutions that meet specific requirements for speed, data integrity, and capacity. The controller card utilizes a standard PCI bus interface, ensuring compatibility with a wide range of server and workstation motherboards. It typically features both internal and external SCSI connectors, allowing for flexible system configurations. The Adaptec ASR-2120S is a reliable choice for applications requiring high-throughput, fault-tolerant storage, particularly in environments that still rely on SCSI infrastructure.
