Introduction

Choose an Adaptec Unified Serial™ controller to leverage cost-effective, high-capacity Serial ATA (SATA) disk drives or high-performance Serial Attached SCSI (SAS) drives, or both, in a single storage system. With Adaptec Unified Serial controllers, you can scale up to 60TB (using 500GB drives) and increase performance for SATA and SAS storage.

Attach directly to SATA and SAS midplanes with up to 12 disk drives or increase capacity using SAS expanders. With an x8 lane, 800 MHz processing power and 256MB of memory, your large capacity solutions will maximize performance and scalability.

The Adaptec RAID 31205 is a 12-port controller that supports SATA and SAS drives and next-generation PCIe connectivity. It features Adaptec RAID Code (ARC) with RAID levels 0, 1, 1E, 5, 5EE, 6, 10, 50, 60, JBOD, as well as Copyback Hot Spare and optional Snapshot Backup.

The card has 256MB of DDR2 memory and a battery unit is optional. Adaptec Storage Manager™ provides one-view, centralized management for all Adaptec RAID controllers.
