The new products are designed to offer easy-to-deploy storage clustering and are being marketed for use in performance-intensive applications such as virtual desktop infrastructures (VDI), online transaction processing (OLTP) and databases.

Nimble Storage also announced a new version of its operating system. Nimble OS 2.0 is the glue that allows users to cluster the performance or capacity arrays together, providing linear scaling of both, as well as a unified management interface.

Nimble Storage, which with its first product, has sold SAN arrays that combine solid-state drives (SSDs) with high-capacity hard disk drives. The arrays serve as both primary and backup storage with the ability to replicate data offsite for disaster recovery.

The new products include the ES-Series expansion shelves, which allow users to incrementally boost performance through the addition of SSDs and CPU upgrades, and the CS400 series arrays, which allow users to grow only storage capacity. The arrays can be used alone or they can be added with no downtime to existing CS200 series array controllers and can be used for performance-intensive applications.

"This allows customers to be able to scale a deployment to meet their needs at the lowest incremental cost -- whether they need more capacity, performance or both," said Dan Leary, vice president of marketing for Nimble.
