Adaptec RAID 6405 2270000-R 6Gb/s SATA/SAS 4 internal ports w/512MB cache memory Controller Card, Single

Adaptec RAID 6405 Unified Serial RAID Controller

As a member of the widely acclaimed Adaptec Series 6 RAID controllers, the Adaptec RAID 6405 Unified Serial RAID controller delivers exceptional performance, advanced data protection, and maximum scalability for enterprise-class, high-density server applications.

This controller supports up to 256 SATA or SAS devices by using SAS expanders. It comes equipped with PMC-sierra PM8013 Dual Core RAID-on-chip and 512MB DDR2 667MHz cache to provide exceptional server RAID IOPS and bandwidth, perfect for bandwidth intensive storage applications, like NAS, OLTP servers, web servers, etc.. It has an SAS 2.0 interface and a PCI Express 2.0 x8 host interface for fast data transfer. It features Adaptec Intelligent Power Management for improved energy-efficiency, plus Zero-Maintenance Cache Protection (ZMCP - pronounced "zemcap") to help data centers save thousands of dollars in operating costs. Its low-profile design allows for seamless, easy installation. An additional low profile vented bracket is also included.

Highest Performance

Adaptec Series 6 RAID controllers deliver up to 60% higher sustained sequential throughput than previous generation Adaptec controllers and up to 2Gbps sustained data transfer rate to the host. At peak performance, Adaptec Series 6 RAID controllers offer 4.8 Gbps through the SAS 2.0 interface and 4.0 Gbps through the PCI Gen 2 host interface.

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, Adaptec Series 6 RAID controllers offer maximum performance and reliability by combining Solid State Drives (SSDs) and Hard Disk Drives (HDDs) in a single mirroring 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.

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. Savvy network administrators know that 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.

Zero-Maintenance Cache Protection

RAID controllers typically employ battery backup units (BBUs) to protect cached data during power loss, but BBUs require constant monitoring and preserve data for a maximum of 72 hours during power loss. Adaptec Series 6 RAID controllers include Zero-Maintenance Cache Protection, a revolutionary advancement that solves BBU deficiencies by providing full protection to cached data with no installation, monitoring, maintenance, disposal, or replacement costs. ZMCP features 4GB of SLC based NAND flash memory with super capacitor technology (available as a separate Kit).

Intelligent Power Management

Intelligent Power Management (IPM) slashes power and cooling costs by up to 70% using intelligent I/O caching combined with disk drive power savings via standby and power-off modes.

One-view Storage Management

Adaptec Series 6 RAID controllers operate under Adaptec Storage Manager, a one-view tool that centralizes management of all Adaptec RAID products.

Broad Operating System Support

Adaptec Series 6 RAID controllers support all major operating systems, including Windows, Linux, VMware and FreeBSD. Adaptec Series 6 RAID controllers have been extensively tested with third-party components to deliver the utmost in compatibility.
