840. Today's global organizations
depend upon the ability to unlock business insights from massive volumes of data, and they need to be
able to do it faster than the competition. Flash technology has changed the economics of today's data
center by eliminating storage bottlenecks. Flash technology has redefined the performance, efficiency,
and reliability of data-intensive applications. In fact, IBM flash storage offerings provide extreme
input/output operations per second (IOPS) performance in a power-efficient footprint.
FlashSystem 840 is optimized for the data center to enable organizations of all sizes to strategically
harness the value of stored data. IBM FlashSystem 840 delivers a competitive advantage for the modern
organizations and enterprises. It provides flexible capacity and extreme performance for the most
demanding applications, including virtualized or bare-metal online transaction processing (OLTP) and
online analytical processing (OLAP) databases, virtual desktop infrastructures (VDI), technical computing
applications, and cloud environments. The system accelerates response times with IBM MicroLatency
™
access times as low as 90 µs write latency and 135 µs read latency to enable faster decision making.
The introduction of a low capacity 1 TB flash module allows FlashSystem 840 to be configured in capacity
points as low as 2 TB in protected RAID 5 mode. Coupled with 10 GB iSCSI, FlashSystem is positioned to
bring extreme performance to small and medium sized businesses (SMB) and growth markets. Figure 1
shows FlashSystem 840.

FlashSystem 840 provides four flexible interface types including Fibre Channel, Fibre Channel over
z
Ethernet (FCoE), iSCSI, and InfiniBand to easily integrate into existing SAN environments.
FlashSystem 840 is cloud-optimized with support for 10 Gbit iSCSI interfaces, allowing private cloud
z
environments and Managed Service Providers (MSPs) to take advantage of high-performance
storage inside existing Ethernet-based infrastructures.
All active parts are hot-swappable, including the flash modules.
