Introduction

High-Availability SAN Delivering Great Price Performance

Flexible Scalability

This storage solution supports dynamic scaling to aid in the planning for future storage growth while satisfying the current storage needs. Flexible drive type and capacity support (SAS, SATA and various drive sizes) allows for the accommodation of current application needs while future proofs to support tomorrow’s applications. This storage solution can be expanded to more than one hundred drives to meet the proliferation of storage growth. The “scale as you grow” flexibility of the storage solution minimizes the upfront investment and provides the best overall Total Cost of Acquisition (TCA).
