Microsemi ADAPTEC 6445 bulk

Unified 8 port (4x internal, 4x external) SATA/SAS controller with 512MB DDR2 dedicated buffer, providing maximum performance, scalability and flexibility. Its biggest benefits include support for both high capacity SATA and high speed SAS hard disks. It can be used anywhere with high demands on intensive storage such as NAS systems, OLTP servers, web servers, or surveillance centres are required.
With the enhanced 6Gbit/s SAS 2.0 interface, the PCI Express 2.0 interface, which connects internally to the controller, allows up to 60% more continuous serial data transmission than previous generations of controllers. This low profile version will provide 4 ports with RAID configurations of 0, 1, 1E, 5, 5EE, 6, 10, 50, 60. Up to 256 SATA or SAS hard drives are supported when using the optional expander. Also interesting is the support of hybrid RAID 1 and 10, where it is possible to combine SSD and HDD.
The controller is based on the PMC-Sierra PM8013 2-core chip, which has a bit rate of up to 2GB/s. The peak performance is then up to 4.8GB/s via SAS 2.0 and 4GB/s via the PCI Express 2.0 interface (8 lines). The advantage of the model is support for various versions of operating systems, compatibility with more than 300 third party devices, and full integration with Adaptec Storage Manager for centralised management of RAID controllers through a JAVA based graphical user interface with SNMP and SMTP monitoring protocol support.
The optional Adaptec Flash Module 600 (AFM-600), using Zero-Maintenance Cache Protection with 4GB of NAND flash memory, replaces the backup battery packs and aims to eliminate data loss in the event of a power failure. The controller is supplied in a "bulk" package without any accessories.
