Adaptec RAID 2805
The entry-level Series 2 family of Unified Serial controllers brings hardware RAID into low-cost disk and tape storage environments
8 internal port, low profile Unified Serial PCI Express controller with Intelligent Power Management and hardware RAID for cost-effective reliability and performance for entry-level applications
The Series 2 family of Adaptec Unified Serial™ (SATA/SAS) RAID controllers leverages the same industry-leading dual-core hardware RAID design as our industry-leading Series 5 Performance RAID controllers.
The Adaptec RAID 2805 features 800 MHz of processing power, a 128MB of DDR2 write cache, connectivity with the latest x8 PCI-Express, and direct I/O connectivity for SATA/SAS tape devices and hard drives. Using SAS expanders, it supports up to 128 devices.
The Adaptec RAID 2805 supports a wide 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.
