IBM System Storage DCS3700

Tab navigation


The era of big data is here, driven by the need for more data and faster data access. Low-latency performance in applications such as real-time business analytics, life sciences research, rich-media entertainment, weather forecasting, social media feeds and stock market transactions require high-performance storage architectures. In addition, today’s organisations need ways to improve operational efficiency while maintaining the same data centre (DC) footprint, quality of service (QoS) and high availability (HA).

The IBM System Storage DCS3700 storage system is ready to meet the challenge. Designed for applications with high performance streaming data requirements, DCS3700 offers optimal space utilisation, low power consumption and high performance. By combining proven IBM storage controllers with up to 60 drives in just 4U of rack space, DCS3700 can reduce operational costs for capacity-intensive applications.

DCS3700 provides a simple, efficient and flexible approach to storage that is based on seven generations of design knowledge and firmware development. DCS3700 can act as a cost-effective, fully integrated complement to IBM System x, IBM BladeCenter and IBM Power Systems servers for a wide variety of intensive computing environments.

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.
