Highlights

To build a sustainable advantage in a world of around the clock continuous operations, organisations of all sizes, from small to enterprise, must adopt a data agenda to extract the full value of their vast and complex data sets. Because data is the new business currency, organisations must quickly and efficiently transact, analyse and gain actionable insight from it to fully capitalise on its value. The IBM FlashSystem family empowers organisations to take advantage of best-in-breed solutions that provide extreme performance, macro efficiency and microsecond (μs) response times. As a result, these organisations can quickly harness the value of data within their data architecture – and be better positioned to compete, innovate and grow in today’s real-time world.

IBM FlashSystem 840 is data centre (DC) optimised to strategically harness the value of stored data. By providing extreme performance for the most demanding applications, including online-transaction processing and analytics databases, virtual desktop infrastructures, technical-computing applications and cloud environments, FlashSystem 840 delivers a competitive advantage for today’s organisations. The IBM system reduces response times with MicroLatency – that is, less than 135 μs access times. It is this consistent low latency that enables FlashSystem to deliver application performance improvements.

Systems

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

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.

Networking

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.

Software

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.
