¡¤ Provide extraordinary system availability with full hardware redundancy built on the market-proven IBM Power Systems™ architecture
¡¤ Dynamically optimize performance for single- and multi-tiered systems with IBM System Storage® Easy Tier® and other self-tuning features
¡¤ Allow systems to scale to more than 2.3 petabytes and support different drive tiers
¡¤ Address the broad scope of storage workloads that exist in today¡¯s complex data center
Virtually every organization in the private and public sector struggles to manage the exponential growth of stored data and the increasing complexity of their IT environments. Managing this extraordinary growth is complicated by the variety of server environments spread across data centers, and for most clients, each server environment can have a distinct storage environment that must be managed separately. As the number of servers grows, managing these disparate storage systems can significantly increase storage costs.
Through its extraordinary flexibility, the IBM System Storage DS8000® series is designed to effectively and efficiently manage a broad scope of storage workloads that exist in today¡¯s complex data centers. This flagship IBM disk system can bring simplicity to your storage environment by supporting a mix of random and sequential I/O workloads, and interactive and batch applications, regardless of whether they are running on one of today¡¯s popular distributed server platforms or on the mainframe. With the ability to manage all these workloads simultaneously, this dynamically self-tuning system can greatly reduce the challenge of managing your increasingly complex storage environment as requirements change.
The DS8000 series delivers these capabilities with a range of features that provide self-tuning performance through automated storage tiering, automated quality-of-service (QoS) management, as well as broad server support and outstanding scalability. The I/O Priority Manager feature, for example, can dynamically manage the performance of the various applications running on the system through a very easy and intuitive approach. This is especially helpful when you want to consolidate storage workloads and need to ensure that system resources are aligned to the priority of your applications. These advanced features can help your business manage more data for more applications in a smaller footprint, without the constant oversight and manual performance tuning that other high-end storage vendors require.
