The IBM System Storage DS8000 offers high-performance, high-capacity, secure storage systems that are designed to deliver the highest levels of performance, flexibility, scalability, resiliency and total overall value for the most demanding, heterogeneous storage environments.
World-class performance to help optimise responsiveness in an on-demand world
The DS8000 series and is built on powerful and market-proven IBM POWER microprocessors in dual two-way or dual four-way shared Symmetric Multi-Processor (SMP) complexes. The new DS8800 model introduces a new generation of hardware and is the fastest disk system in the IBM storage portfolio. With dual IBM POWER6+ controllers, 8 Gbps host and device adapters, as well as 6 Gbps SAS disk drives, the DS8800 delivers a new level of performance in a design that condenses more data in a smaller footprint. Compared to the POWER6 processor in DS8700 models, the POWER6+ processor offers up to over a 40 percent performance improvement. Whats more, the new 8 Gbps host adapters effectively double the single-port performance of the DS8700. These upgrades, along with the new 2.5-inch SAS drives, deliver a dramatic boost in data throughput in a more compact footprint a powerful combination aimed at taming the most demanding enterprise applications.
The decision to base the DS8000 design on the IBM Power architecture is complemented by two additional tiers of high-performance processors within the systems host and device adapters, which are designed to further add to the DS8000s outstanding, balanced performance.
The efficiency of a storage systems cache can also greatly improve input/output (I/O) performance, as well as reduce the systems overall cache requirements. The caching algorithms in the DS8000 series are designed to intelligently and dynamically adapt system caching to the specific needs of the current workload. This is intended to help the system deliver an unimpeded flow of information for outstanding throughput. One example is the Intelligent Write Caching algorithm, which combines and balances the benefits of the most effective read and write caching algorithms to determine how the write cache should be managed for optimal throughput. Another is the Adaptive Multistream Pre-fetching (AMP) algorithm, which is designed to dramatically improve performance for sequential and batch processing applications, such as data backup, business analytics and data warehouse workloads.
The DS8000 series also includes a variety of features designed to extend the performance of IBM server environments. The Cooperative Caching and I/O Priority functions can help enable greater cache efficiency and performance for higher priority IBM DB2 applications running on IBM System p servers with the IBM AIX operating system. And recent enhancements for High Performance FICON for System z (zHPF) enable users to enjoy faster performance over longer distances.
In addition to its performance gains, the DS8700 model reuses over 90 percent of the microcode of the previous DS8300 model to help address the reliability and high availability requirements expected of high-end disk systems. The new DS8800 model reuses over 85 percent of the microcode of the DS8700. Existing clients will also appreciate the fact that most remote mirror and copy functions are interoperable across both older and newer DS8000 models, as well as with older IBM TotalStorage Enterprise Storage Server (ESS) models. This underscores our commitment to providing our clients the performance, reliability and value youve come to expect from IBM.
Make business continuity (BC) a reality with high-availability architecture
The DS8000 series is designed to help address the needs of dynamic environments requiring the highest levels of availability. It is designed to support dynamic system changes, such as online system microcode updates and online hardware upgrades. The DS8000 also features redundant, hot-swappable components to help support continuous operations. This highly resilient design and its five-nines availability can make the DS8000 series an ideal storage platform for supporting todays around-the-clock, global business environment.
All disks are RAID-protected, such that multiple spare disks are configured in a RAID group to allow a failed, RAID-protected disk to be rebuilt quickly and automatically to maintain access to information. The DS8000 series supports RAID-5, RAID-6 and RAID-10 configurations for increased flexibility. Each DS8000 system is built to monitor its own internal functions, so it can call home automatically to alert service personnel if it detects a potential problem arising. Sophisticated Light Path Diagnostics also facilitate system maintenance and the DS8000 series also offers an audit log security function designed to log changes made by administrators to aid in root cause analysis.
In addition to its exceptionally resilient architecture, the DS8000 series offers an array of advanced functions for data backup, remote mirroring and disaster recovery (DR). The DS8000s advanced two-site and three-site BC capabilities can give you the peace of mind of knowing your mission-critical applications will be available when you need them during both planned and unplanned system outages. For applications that cannot suffer any data loss in the event of a failure, IBM Metro Mirror provides the foundation for exceptionally fast mirror-based recovery time. IBM Global Mirror can keep data at the remote site current to within three to five seconds of the local site. With this type of resiliency and high availability, its no wonder clients turn to the DS8000 to support their most important business applications.
Adapt to a changing world with exceptional flexibility and scalability
The DS8000 series is known for its unique combination of flexibility, resiliency, performance and scalability, which can help address the many challenges stemming from the exponential growth of data across the enterprise. Savvy businesses are looking for innovative ways to manage and adapt in todays increasingly competitive, global business environment and the DS8000 series is designed to meet this challenge with broad interoperability and support for open industry standards.
To help accommodate real-time workload fluctuations, the DS8000 series supports the addition, deletion and dynamic expansion of storage capacity as and when needed to help meet sudden spikes in demand or to react to other environmental changes. Dynamic Volume Expansion and Thin Provisioning can not only help reduce the need to disrupt your applications to add capacity, these features also can significantly reduce the amount of time administrators spend provisioning new storage, which can help reduce management costs across your environment.
If your organisation needs the flexibility to run a mix of performance-optimised workloads alongside those that might require a little less performance, yet still provide the reliability that a tier-one disk system affords, the DS8000 can help with that, too. With the capability to adeptly balance workloads on different tiers of drives (e.g. SSDs, FC, SAS, SATA), you can have all the flexibility you need to consolidate a variety of disk platforms on a single DS8000 system and the Easy Tier feature makes workload optimisation even easier. Another example of the flexibility and modularity of the DS8000 series is the ability to increase physical storage capacity within a frame or a drive enclosure without system disruption
The DS8000 series also supports a variety of major server platforms, including IBM z/OS, z/VM, Linux on System z, OS/400, i5/OS and AIX operating systems, as well as Linux, HP-UX, Sun Solaris, Novell NetWare, VMware and Microsoft Windows environments, among others. With such broad platform support, the DS8000 series can easily accommodate a wide array of applications and their distinct service levels.
