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. Now, flash technology and software-defined storage are available in one solution that provides flexible deployment architectures, extreme performance, simplified management and a fast return on investment (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 data lifecycle, 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.

IBM offers a broad systems and storage portfolio combined with decades of experience solving real business problems. With x86, POWER and mainframe systems, disk, tape and network storage systems, IBM can offer the right combination of systems to meet the challenges of your business.


Storage efficiency is more vital than ever. Your disk utilisation rate may be as low as 20% — while the amount of data you are required to store is exploding. IBM Storage can help.


The smarter data centre with improved economics of IT can be achieved by connecting servers and storage with a high-speed and intelligent network fabric that is smarter, faster, greener, open and easy to manage. IBM takes an open, standards-based approach to implement the latest advances in today’s flat, converged data centre network designs.


IBM's comprehensive Systems Software solutions help to centralise, streamline and automate your physical and virtual infrastructure, allowing you to optimise workloads and increase your ability to deliver IT services that align with business goals. Let us show you how IBM Systems Software helps you realise the value of IBM smarter computing, by allowing a more effective use of the advanced features in IBM hardware and operating systems.

Integrated solutions

The reality is that you need an IT infrastructure designed for data, tuned to the task and managed in the cloud. If your IT staff spends all of their time managing IT, they won’t be working with you to drive innovation. You need your infrastructure to help you in the marketplace, to help you innovate, to help you be more competitive, to help you succeed.

Systems-related services

IBM Systems-related services offers a full range of services to help design, develop, integrate, optimise, validate and deploy comprehensive solutions that support On Demand Business.
