  • Improve the economics of IT by easily integrating with existing infrastructure to maximize total cost of ownership and return on investment
  • Operate at peak efficiency with IBM® MicroLatency™, high bandwidth, flexible connectivity and low wattage—all in a 2U footprint
  • Add enterprise management features with IBM System Storage® SAN Volume Controller
  • Boost reliability with enterprise-class flash storage and patented data protection technology
  • Offer scalable performance in storage devices that are both space and power efficient
To build a sustainable advantage in a world of 24×7 continuous operations, today’s enterprise organizations must be able to extract the full value of their vast and complex data sets. Because data is the new business currency, organizations must quickly and efficiently transact, analyze and gain actionable insight from it to fully capitalize on its value. The IBM FlashSystem™ family empowers organizations to take advantage of best-in-breed solutions that provide extreme performance, macro efficiency and microsecond response times. As a result, these organizations can quickly harness the value of stored data—and be better positioned to compete, innovate and grow in today’s real-time world. IBM FlashSystem 840 is data center-optimized to enable organizations to strategically harness the value of stored data. By providing flexible capacity and extreme performance for the most demanding enterprise-class applications, including OLTP and OLAP databases, virtual desktop infrastructures, technical-computing applications and cloud-scale environments, FlashSystem 840 delivers a competitive advantage for the modern enterprise. The IBM system accelerates response times with MicroLatency—that is, less than 135-microsecond access times—to enable faster decision making. In addition to optimizing performance, FlashSystem 840 delivers best-in-class reliability in a storage device that is both space and power efficient.
