Product Description
The Adaptec 4800SAS is a powerful enterprise-grade RAID controller engineered to deliver exceptional performance and scalability for storage-intensive environments. Featuring a PCI Express 2.0 x8 interface, it provides ample bandwidth for high-speed data transfers, making it suitable for demanding applications such as video editing, large databases, and virtualization. The card is equipped with eight external SAS ports, enabling connectivity to a large number of storage devices, including hard drives and SSDs, through direct connections or SAS expanders. This controller supports a comprehensive suite of RAID levels, including RAID 0, 1, 5, 6, 10, 50, and 60. This extensive support allows for highly flexible storage configurations, catering to needs ranging from maximum performance (RAID 0) to robust data protection with advanced parity schemes (RAID 6, RAID 60). The integrated RAID-on-Chip (ROC) processor handles all RAID calculations, significantly reducing the burden on the host CPU and ensuring efficient operation even under heavy load. It comes standard with 256MB of DDR2 cache memory, further enhancing performance. Designed for reliability and advanced data protection, the Adaptec 4800SAS can manage up to 128 drives when used with SAS expanders, offering significant scalability for growing storage requirements. It also supports an optional battery backup module (BBU) for the cache memory, which protects data in the cache during unexpected power outages, preventing data loss and corruption. This makes the 4800SAS a critical component for mission-critical servers and storage arrays where data integrity and availability are paramount.
