Datasheet: Adaptec Series 5 Unified Serial™ Controllers

Adaptec next-generation Unified Serial controllers deliver both high I/O transaction and high bandwidth processing for use with cost-effective, high-capacity Serial ATA (SATA) disk drives or high-performance Serial Attached SCSI (SAS) drives, or both attached to the same controller. With an industryleading dual core RAID on Chip (ROC), DDR2 533MHz write cache, support for up to 256 SATA/SAS devices (using SAS expanders), and an x8 PCI express host interface bus connection, this family of Adaptec Unified Serial controllers delivers impressive performance numbers — over 250,000 I/Os and 1.2GB/s. These controllers are ideal for enterprise-class storage applications that call for maximum performance, scalability and flexibility.
