IBM System Storage DS5000 series

The IBM System Storage™ DS5000 series storage system is designed to meet today’s and tomorrow’s demanding open-systems requirements while establishing a new standard for life cycle longevity. Building on many decades of design expertise, the DS5000 series’ seventh-generation architecture delivers industry-leading performance, real reliability, multi-dimensional scalability and unprecedented investment protection.

The DS5000 series is equally adept at supporting transactional applications such as databases and OLTP, throughput-intensive applications such as HPC and rich media, and concurrent workloads for consolidation and virtualization. With its relentless performance and superior reliability and availability, the DS5000 series storage system can support the most demanding service level agreements (SLAs). And when requirements change, you can add or replace host interfaces, grow capacity, add cache and reconfigure the system on the fly—ensuring that it will keep pace with your growing company.

This multi-dimensional scalability enables the DS5000 series storage system to extend beyond the normal three- to four-year life cycle, protecting your storage investment by delaying (or even eliminating) the expense of migrating data to a new system and allowing you to amortize acquisition costs over extended periods of time. This life cycle longevity enables the DS5000 series to continue delivering value long after other systems have been retired. The DS5000 series’ drive-level encryption offers affordable data security with no performance penalty. And the DS5000 series’ multiple replication options and persistent cache backup can help ensure that any data in cache is captured and safe in the event of a power outage.
