The ASR-71405 utilized in this evaluation sports an unmatched 24 native SAS/SATA ports in a full-height half-length form factor.
The ASR-72405 features 24 x 6Gb/s SAS native ports combined with the x8 PCIe Gen3 interface. 16 ports alone can saturate the bus by providing 9.8 GB/s, well above the 8 GB/s supplied by PCIe Gen3. This allows Adaptec to pack as many lanes onboard the controller as possible.
The heart of the Series 7 RAID controllers is the PMC8015 processor. This very small chip packs quite the punch, delivering 6,600 MB/s in sequential speed and 450,000 IOPS in random read speed. Developed by PMC-Sierra, this cornerstone of the Series 7 controller provides Adaptec with a 24-port SAS 2.0 native solution that easily outstrips an x8 PCIe Gen3 connection.
Adaptec paired this powerful controller with the new Mini-SAS HD (High Density) cables. These new RAID controller interconnects are the only solution that can provide the required number of connections for taking advantage of the ROC's 24 available ports within the space limitations of the full height controller.
Combining a revolutionary new controller with advanced cabling provides extreme performance, a slim form factor, and enhanced density that no other product currently on the market can match.
Adaptec RAID Code (ARC) delivers RAID levels 0, 1, 1E, 5, 6, 10, 50 and 60 (71605E supports 0, 1, 1E, and 10, only). 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).
Adaptec's Intelligent Power Management techniques can purportedly reduce storage power consumption, and thus cost, by up to 70%. This is enabled by shifting the power for the connected devices into one of three modes; full on, low power and spin down.
The ASR-72405 is backed by a three year warranty.
