The 2882 controller combines industry-standard components with robust Engenio firmware to deliver enterprise-class functionality and exceptional performance value. The 2882 features:

• 2 Gb/s host interfaces
• dual 2 Gb/s drive channels
• 1 GB of cache
• outstanding MB/s and IOPS performance.

The cost-effective 2882 controller delivers the features and performance required from energetic workgroup and departmental environments. And if capacity or performance demands increase, the firmware it shares in common with our other controllers enables seamless "data intact" migrations and upgrades to higher-end systems, such as the 5884 controller.

One or two 2882 controllers are integrated into Engenio drive modules to create a single-module storage system. Dual controller 2882-enabled drive modules provide four 2 Gb/s host connections and support up to seven additional drive modules for a maximum storage capacity of 112 disk drives.
