Dell Compellent SC4020 - Enterprise storage features right from the start
 
Enterprise storage features right from the start
Ideal for stand-alone SANs or departmental/branch office deployments, the SC4020 is fully-integrated with the SC Series enterprise-class portfolio. Designed to support distributed large-scale growth, the SC Series portfolio ensures that as your organization grows, so will your ability to manage and access your data.
•Virtualized architecture eliminates need to pre-allocate RAID groups, increases overall flexibility
•Automated tiering among diverse media types7 lets you buy fewer and less-expensive drives to meet your performance and capacity needs
•Space-efficient snapshots, remote synchronous/asynchronous replication and Fast Track disk optimization maximize every drive investment

Industry-leading TCO and investment protection
The space-saving 2U SC4020 chassis includes dual controllers, 24 internal drive slots and high-performance Fibre Channel or iSCSI network ports, helping you lower data center energy costs.
