Adaptec 2244100-R 5805 8-Channel SATA/SAS 512MB PCI-Express LP RAID Controller with Cable Kit

From the Manufacturer

With an industry-leading 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, the Series 5 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.
The Adaptec RAID 5805 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 1.2GB. Using SAS expanders, it can connect up to 256 SATA/SAS devices.
The Adaptec RAID 5805 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. Highest Performance
Series 5 controllers deliver speeds up to five times faster than competing products -- over 250, 000 IOPs and 1.2GB /s -- making them ideal for enterprise-class storage systems. Broad range support of operating systems, also compatible with more than 300 third-party devices
Advanced Data Protection
Adaptec RAID Code (ARC) delivers maximum reliability with RAID levels 0, 1, 1E, 5, 5EE, 6, 10, 50, 60 and JBOD. ARC also offers RAID Level Migration (the ability to easily migrate RAID levels), Online Capacity Expansion (expand capacity without powering down the server), and Copyback Hot Spare (when a failed drive has been replaced, data is automatically copied from the hot spare back to the restored drive). Hybrid RAID
With Hybrid RAID 1 & 10 the Series 5 controllers offer maximum performance and reliability by combining Solid State Drives (SSDs) and Hard Disk Drives (HDDs) in a single array. By performing read operations from the faster SSD and write operations on both the SSDs and HDDs the result is tremendous performance gains over standard HDD RAID arrays. Hybrid RAID offers the benefits of both technologies and allows a better cost per GB ratio than comparable SSD-only RAID arrays. The Case for Cache
The fastest way for a RAID controller to fulfill a read or write request is to serve data out of its cache. Enabling the RAID controller cache offers significant performance benefits, such as reduced latency in I/O requests, bandwidth and queue depths that surpass software application limits, and on-the-fly parity calculations on sequential writes. Intelligent Power Management
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. One-view Storage Management
Adaptec Storage Manager, a one-view tool centralizes management of all Adaptec RAID products. Broad Operating System Support
Extensive operating system support includes all major software releases, such as Windows, Linux, FreeBSD, and UNIX variants. What's in the Box
Adaptec RAID 5805 controller, additional low profile vented bracket, quick installtion guide (English/French/German/Italian/Spanish), software and documentation CDs, two internal Mini SAS x4 to (4x) SATA fan-out cables with sideband ( 0.5 meters). Technical
