1.2 IBM TotalStorage DS6000 series unique benefits

The IBM TotalStorage DS6000 series is a Fibre Channel based storage system that supports a wide range of IBM and non-IBM server platforms and operating environments. This includes open systems, zSeries, and iSeries servers.

In a small 3U footprint, the new storage subsystem provides performance and functions for business continuity, disaster recovery and resiliency, previously only available in expensive high-end storage subsystems. The DS6000 series is compatible regarding Copy Services with the previous Enterprise Storage Server (ESS) Models 800 and 750, as well as with the new DS8000 series.

The DS6000 series offers an entirely new era in price, performance, and scalability. Now for the first time zSeries and iSeries customers have the option for a midrange priced storage subsystem with all the features and functions of an enterprise storage subsystem.

Some clients do not like to put large amounts of storage behind one storage controller. In particular, the controller part of a high-end storage system makes it expensive. Now you have the option of choice: you can build very cost efficient storage systems by adding expansion enclosures to the DS6800 controller, but since the DS6800 controller is not really expensive, you can also grow horizontally by adding other DS6800 controllers. You also have the option to easily grow into the DS8000 series by adding DS8000 systems to your environment or by replacing DS6000 systems (see Figure 1-2).
