Product Description
The Adaptec ASR-5445 RAID controller is engineered to deliver superior storage performance and reliability for demanding server environments. Its PCIe x8 interface ensures high bandwidth connectivity, allowing for rapid data access and transfer speeds essential for applications such as databases, virtualization, and content creation. The integrated 512MB of DDR2 cache memory significantly accelerates I/O operations by buffering frequently accessed data, reducing latency and improving overall system responsiveness. This controller offers comprehensive hardware RAID support, including levels 0, 1, 10, 5, 50, 6, and 60. This broad range of RAID configurations allows administrators to tailor storage solutions to specific needs, balancing performance, redundancy, and capacity. Whether the requirement is for maximum performance with RAID 0, data protection with RAID 1 or 5, or advanced fault tolerance with RAID 6, the ASR-5445 provides the flexibility to meet diverse operational demands. Designed with enterprise scalability in mind, the ASR-5445 can manage up to 128 drives when paired with optional expanders, making it suitable for large-scale storage arrays. The inclusion of Adaptec's proprietary ROC (RAID-on-Chip) technology offloads RAID processing from the host CPU, freeing up system resources for other critical tasks. Furthermore, support for a Battery Backup Unit (BBU) ensures data integrity by protecting cached data in the event of a sudden power outage, preventing data loss and corruption.
