IBM FlashSystem 820 and IBM FlashSystem 720

  • Reduce business interruptions without sacrificing performance or usable capacity, with IBM® Variable Stripe RAID™ technology
  • Accelerate decision making across multiple applications, including online transactional processing (OLTP) and online analytical processing (OLAP) databases
  • Boost IT efficiency and gain high bandwidth and extreme input/output operations per second (IOPS) performance in exceptionally dense, 1U storage systems—without compromising on latency
  • Realize macro efficiencies with green storage for data centers, designed for fast data access at low wattage
  • Extract immediate value from your investment with quick time to deployment
  • Leverage single-level cell (SLC) or enterprise multi-level cell (eMLC) flash technologies
  • Enable organizations to quickly uncover business insights using traditional data analytics as well as varying big-data technologies
  • Offer scalable performance in storage devices that are both space and power efficient

To achieve a competitive advantage in a world of 24×7 continuous operations, organizations need to perform more frequent and complex analytics on vast volumes of data—including varying types of big data—and they cannot afford downtime. IBM flash storage offerings provide extreme IOPS and microsecond latency performance to turbocharge these new IT infrastructures. When compared to equivalent disk systems, IBM flash storage solutions deliver 6.7 times more capacity in a single rack, 19 times more cost efficiency in dollars/per IOPS, and are 115 times more energy efficient.1

IBM FlashSystem™ 820 and IBM FlashSystem 720 are designed to speed up the performance of multiple enterprise-class applications, including OLTP and OLAP databases, virtual desktop infrastructures, technical computing applications and cloud-scale infrastructures. These IBM systems deliver extreme performance per gigabyte, so organizations can quickly uncover business insights using traditional data analytics as well as new, big-data technologies. In addition, FlashSystem 820 and FlashSystem 720 eliminate storage bottlenecks with IBM MicroLatency™—that is, less than 100-microsecond access times—to enable faster decision making. With these low latencies, the storage disk layer can operate at speeds comparable to those of the CPUs, DRAM, networks and buses in the I/O data path.
