ASR-5805 - Adaptec 5805 8-Port PCI Expressxpress X8 SATA/SAS Low Profile RAID Controller with 512MB DDR2

Description

The Adaptec ASR-5805 is a powerful RAID controller designed to provide advanced storage management and data protection for a wide range of server and workstation applications. It supports both SATA and SAS drives through its unified port architecture, offering flexibility in drive selection and configuration. With a substantial 512MB of onboard cache memory, this controller accelerates data transfer operations by buffering frequently accessed data, significantly improving read and write performance, especially in I/O-intensive workloads. This controller utilizes a PCIe x8 host interface, typically adhering to the PCIe 2.0 standard, which provides ample bandwidth for high-speed data transfer between the drives and the host system. The ASR-5805 supports an extensive array of RAID levels, including RAID 0, 1, 5, 6, 10, 50, and 60. This broad support allows for highly customized storage configurations, enabling administrators to achieve optimal balance between performance, data redundancy, and capacity. Support for RAID 6 and RAID 60 offers enhanced data protection with dual-parity capabilities. Built with Adaptec's RAID-on-Chip (ROC) technology, the ASR-5805 offloads RAID processing from the host CPU, ensuring that system resources are available for applications. It also typically supports optional Battery Backup Units (BBUs) or CacheVault modules to protect data in the cache during power failures, ensuring data integrity. Capable of managing up to 128 SATA or SAS devices, this controller is a robust solution for building scalable and reliable storage arrays in demanding enterprise environments.
