IBM FlashSystem V840
Enterprise Performance Solution

Accelerate applications and improve data economics with flash storage and advanced data services


Today’s storage capacity and performance requirements are growing faster than ever before – and the costs of managing this growth are eating up more and more of the typical IT budget. Flash storage addresses your performance requirements, while software-defined storage simplifies data management, improves data security and preserves your investments in legacy storage. Flash technology and software-defined storage are now available in one solution that provides flexible deployment architectures, extreme performance, simplified management and a fast ROI.

The market for all-flash arrays is saturated with products aiming to replace enterprise storage arrays but consistently failing to deliver the breadth of storage services or the scalability delivered by incumbent solutions. Alternatively, hybrid arrays loaded with storage services consistently lack the low latency and performance scalability delivered by all-flash arrays.

IBM FlashSystem V840 Enterprise Performance Solution merges IBM software-defined storage with the scalable performance of IBM FlashSystem storage to accelerate critical business applications and decrease data centre (DC) costs simultaneously. As a result, your organisation can gain a competitive advantage via a more flexible, responsive and efficient storage environment.
