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.
