IBM System Storage DS3400 Express


As a business matures, so does the amount of data and the value of the data that it holds within the organisation. If the data is distributed across servers and individual storage systems, the business will face increased cost and complexity along with the accompanying business risks.

The IBM System Storage DS3400 Express leads the way for these organisations to take advantage of consolidating and sharing this data within a direct-attach or FC SAN solution. The DS3400 Express adds the most advanced front-end 4 Gbps FC technology to IBM time-proven designs for enterprise-class Redundant Array of Independent Disk (RAID) storage. With FC host connectivity and SAS back-end technology, the DS3400 Express is designed to improve productivity through data consolidation, availability, performance and scalability.

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.
