The new enterprise-class CS400 array product line includes the CS420, with 12TB of disk capacity and 320GB of flash; the CS440, offering 24TB of raw capacity and 640GB of flash; and the CS460, offering 48TB of raw capacity and 1,200GB of flash.

The CS400 arrays extend the family of Nimble SAN servers, following on the success of the company's flagship CS200 arrays.

Scale performance consists of SSD and CPU upgrades to increase raw computational power and IOPS (input/output operations per second). Scale capacity is provided by new ES-Series expansion shelves, which deliver three incremental levels of raw capacity and flash: ES-H125 - 15TB raw capacity, 160GB flash; ES-H145 - 30TB raw capacity, 300GB flash; and ES-H165 - 45TB raw capacity, 600GB flash.

The CS400 series arrays, ES-Series expansion shelves and flash expansion options will be available in the third quarter of 2012. Nimble OS 2.0, which supports scale-out clustering, will be available in the fourth quarter of this year. Pricing was not yet available.
