IBM System Storage DS8000 series

Optimised flash performance and superior resiliency for the most demanding storage environments


Smarter storage, such as IBM DS8870, can help organisations spend less time managing storage and more time exploring ways to exploit data to grow their businesses. Quick and reliable data access is the driving force behind important data initiatives such as cloud, business analytics and mobile computing and the sixth-generation DS8870 system sets the standard for what an enterprise storage system should be with extraordinary performance, reliability and agility.

As the latest model in the IBM DS8000 series, DS8870 can bring simplicity to your data architecture with self-optimising performance for both random and sequential application workloads for the mainframe and an extensive variety of distributed server platforms. With the agility and automation to manage all these workloads simultaneously, DS8870 can greatly reduce the challenge of managing your increasingly complex storage environment as your business requirements change.

The logical choice

To support your most demanding, business-critical applications, DS8870 combines rock-solid resiliency and intelligent flash performance to deliver consistent microsecond (μs) application response times.1 The ability to select from all-flash, hybrid-flash or traditional disk configuration options gives the confidence needed to support the dynamic applications that sit at the heart of your business. To that end, DS8870 delivers a range of self-tuning features – such as intelligent caching algorithms, automated QOS management and advanced storage tiering that can even optimise data placement between itself and the enterprise servers attached to it. DS8870 also boasts high availability (HA) and exclusive integration with IBM enterprise servers that deliver extraordinary value. For organisations seeking an ideal combination of performance, HA, resilience and agility, DS8870 is a logical choice.

DS8870 is a high-performance, high-capacity, secure storage system designed to deliver the highest levels of performance, flexibility, scalability, resiliency and total overall value for the most demanding, heterogeneous storage environments.
