Product Description
The Adaptec ASR-6805-LP is a high-performance RAID controller engineered to provide robust data protection and enhanced storage performance for demanding server and workstation environments. Its low-profile design makes it suitable for installation in compact chassis, such as 1U or 2U rackmount servers, where space is at a premium. The controller utilizes Adaptec's RAID-on-Chip (ROC) technology, integrating the RAID logic directly onto the controller's ASIC for optimized performance and efficiency. This controller supports both SAS and SATA drives, offering flexibility in storage configurations. With a data transfer rate of 6Gb/s per lane and an interface based on PCI Express 2.0 x8, it ensures high-speed communication between the host system and the storage devices. The inclusion of 512MB of DDR2 cache memory further accelerates I/O operations by buffering frequently accessed data, significantly reducing latency and improving overall system responsiveness. The ASR-6805-LP supports a comprehensive range of hardware RAID levels, including RAID 0, 1, 10, 5, 50, 6, and 60. This allows administrators to implement various levels of performance and redundancy tailored to specific application needs, from high-speed striping (RAID 0) to advanced fault tolerance (RAID 6/60). The controller's ability to manage up to eight internal drives provides ample capacity for storage expansion within a single system.
