Adaptec Series 6 RAID controller features PMC Sierra's multi-core SRC 8 x 6 G RAID-on-Chip (ROC) and an x8 PCI Express Gen 2 host bus connection. It supports up to 256 SATA/SAS devices and 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.

Adaptec Series 6 and Series 6T RAID controllers feature PMC-Sierra's market-leading, multi-core SRC 8x6G RAID-on-Chip (ROC), 512MB DDR2 667MHz cache, and an x8 PCI Express Gen 2 host bus connection. They support up to 256 SATA/ SAS devices and feature 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. Series 6 and Series 6T controllers contain the same performance and features; Series 6T controllers include recessed top-mounted connectors.
Highest PerformanceSeries 6 and Series 6T controllers deliver up to 60% higher sustained sequential throughput than previous generation Adaptec controllers and up to 2GB/s sustained data transfer rate to the host. At peak performance, Series 6 and Series 6T offer 4.8GB/s through the SAS 2.0 interface and 4.0GB/s through the PCI Gen 2 host interface.
Advanced Data ProtectionAdaptec 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 RAIDWith Hybrid RAID 1 & 10 the Series 6 and Series 6T 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 CacheThe 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 ProtectionRAID 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. Series 6 and Series 6T 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 ManagementIntelligent 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 ManagementSeries 6 and Series 6T controllers operate under Adaptec Storage Manager, a one-view tool that centralizes management of all Adaptec RAID products.
Hardware Flexibility for Dense ServersThe Series 6T controllers (6405T and 6805T) provide the added hardware flexibility required for very dense server applications by providing a different connector orientation of 4 and 8-port recessed top-mounted connectors. These controllers include all the same performance capabilities and functionality of the Series 6 and support the same AFM-600 module for Zero-Maintenance Cache Protection.
Broad Operating System SupportSeries 6 and Series 6T controllers support all major operating systems, including Windows, Linux, VMware and FreeBSD. Compatibility, Reliability, and Support Series 6 and Series 6T controllers have been extensively tested with third-party components to deliver the utmost in compatibility. The cards are backed by a 3-year warranty and the company's legendary technical support.
