Product Description
The Adaptec 2185800, based on the 4805SAS chipset, is a powerful RAID controller designed to enhance storage performance and reliability in server environments. With its eight SAS ports, it offers extensive connectivity options, allowing for the integration of a large number of SAS drives into a storage array. The PCI Express interface ensures high-speed data transfer between the controller and the host system, which is crucial for I/O-intensive applications. This controller is equipped with 128MB of DDR2 ECC (Error-Correcting Code) cache memory. The ECC functionality is vital for maintaining data integrity by detecting and correcting memory errors on the fly, preventing data corruption. The cache memory itself serves to accelerate read and write operations by buffering data, thereby reducing latency and improving overall system responsiveness. It supports a range of RAID levels, including RAID 0, 1, 10, 5, and 50, providing flexibility in configuring storage for performance, redundancy, or a combination of both. The Adaptec 2185800 is engineered for demanding enterprise applications where data availability and performance are critical. Its robust feature set, including multiple SAS ports and advanced RAID capabilities, makes it a suitable choice for servers, workstations, and storage arrays that require a reliable and high-performing storage solution. The 300MBps transfer rate further contributes to its efficiency in handling large data volumes.
