DS5000.jpgHighlights

  • New seventh-generation architecture with extreme and balanced performance for increased application performance
  • “Pay-as-you-grow” scalability, initially 256 drives, for the most demanding capacity requirements
  • Unique host interface cards designed to provide investment protection and life cycle longevity
  • Designed to support high availability with dual active, hot-swappable controllers, power supplies and many non-disruptive firmware upgrades
  • Heterogeneous support for the most common operating systems, including Microsoft® Windows®, UNIX® and Linux®
  • Architecture efficiently handles compute-intensive parity calculations, enabling exceptional disk-based performance that’s ideally suited for RAID 5 and RAID 6 configurations

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, the DS5000 series can add or replace host interfaces, grow capacity, add cache and be reconfigured 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 its 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.

IBM has a long history of designing highly reliable and available storage systems, and the DS5000 series is the culmination of that expertise. With redundant components, automated path failover and extensive online configuration, reconfiguration and maintenance capabilities, the DS5000 series helps ensure that your data will be available 24x7x365. The DS5000 series also offers multiple replication options and a persistent cache backup to help ensure that any data in cache is captured and safe in the event of a power outage.
