The Series 5 family of high-performance Adaptec Unified Serial (SATA/SAS) RAID controllers offers both high I/O transaction and high bandwidth processing for use with cost-effective, high-capacity SATA drives or high-performance SAS drives.
The Adaptec RAID 51245 utilizes industry-leading dual core RAID on Chip (ROC), 512MB of DDR2 write cache, and connectivity with the latest x8 PCI-Express to deliver over 250,000 I/Os 1.2GBs. Using SAS expanders, it can connect up to 256 SATA/SAS devices.
The Adaptec RAID 51245 supports a broad range of operating systems, compatibility with more than 300 third-party devices, and full integration with Adaptec Storage Manager for centralized management of all Adaptec RAID controllers on the network.
Intelligent Power Management - Reduce Power by up to 70% The power required by disks is a primary ongoing storage cost. Full power is maintained to every disk whether it is actively being used or not, which also increases cooling costs. Adaptec Intelligent Power Management slashes power and cooling costs by spinning down idle disks and providing a lower power mode for active disks.
