PMC-Sierra launches Series 6 raid controllers

In its first new product launch since acquiring Adaptec last spring, PMC-Sierra announced its new Series 6 line of 6Gbps raid controllers.

In its first new product launch since acquiring Adaptec last spring, PMC-Sierra announced its new Series 6 line of 6Gbps RAID controllers. Supporting both Serial Attached SCSI (SAS) and Serial ATA (SATA) interfaces, the Series 6 adapters take advantage of PMC-Sierra's advanced multi-core raid-on-chip silicon. The adapters use an eight-lane PCIe Gen2 host bus interface capable of pumping 4.8GBps peak performance across the SAS 2.0 bi-directional interface.

All versions of the Series 6 controllers can use the optional Zero Maintenance Cache Protection (ZMCP) feature introduced by Adaptec last year. ZMCP uses a super capacitor and NAND FLASH instead of a battery to protect the cache during a power failure. Batteries require expensive and time consuming maintenance because they must be replaced every other year or so. And just like the battery in your phone, when you really need it, it probably will go dead. 

Another advantage is that while batteries may retain cache for a few days, ZMCP will retain the cache for years, providing an additional level of security for extensive power outages associated with disasters.

The Series 6 controllers are sold under the Adaptec brand and come in three models, the 6805 with eight internal ports, the 6445 with four internal and four external ports and the 6405 with four internal ports. The controllers support hardware RAID levels 0,1,1E,5,5EE,6,10,50,60 and Hybrid RAID 1,10 support for arrays of Solid State Drives (SSD) and Hard Disk Drives (HDD) for maximum performance. Scalable to support up to 256 SATA/SAS devices using SAS expanders, the Series 6 controllers can be used to build hybrid arrays of fast SSD devices, SAS drives and low cost SATA drives.

The controllers are now being sampled to select customers and are expected to retail from $395 to $630.
