IBM® FlashSystem™ 840 is an all-flash storage array that provides extreme performance, ultra low-latency, high-density, and high-reliability while providing scalable performance in a storage device that is both space and power-efficient. IBM FlashSystem delivers performance that is driven by IBM MicroLatency™ for quick response time and is easy to integrate. FlashSystem 840 uses IBM Variable Stripe RAID™ and two-dimensional (2D) Flash RAID technologies to maintain performance, protect data integrity, and preserve usable storage capacity. IBM System Storage® SAN Volume Controller is a storage virtualization solution that helps increase the usage of existing storage capacity and centralize the management of multiple controllers in an open-system storage area network (SAN) environment.
For clients who want advanced software features, IBM FlashSystem 840 integrated with SAN Volume Controller provides an enterprise-class solution by utilizing SAN Volume Controller functions and services, such as mirroring, IBM FlashCopy®, thin provisioning, IBM Real-time Compression™ Copy Services, and broader host support that enriches any storage environment without introducing any delay or latency. Figure 1 shows the benefits of IBM FlashSystem 840 integrated with the SAN Volume Controller system.
