IBM set to revolutionize the economics of the storage market

IBM Haifa Labs News Center

October 21, 2004

One's about the size of a refrigerator; the other is the size of a vegetable drawer in a refrigerator - but both of IBM's new storage systems could cause our competitors to shiver.

These new enterprise data storage systems span the once incompatible high-end and mid-range storage classes. They include the world's most massively scalable system and a compatible ultra-dense storage system that's equivalent to EMC systems that are 20 times as large and twice as expensive.

The IBM Research Lab in Haifa played a central role in the development of these products, in areas such as manageability, reliability, availability and serviceability. In addition, the advanced copy functions developed at the lab for IBM's Enterprise Storage Server were enhanced and adapted to support the new architectures of these two systems.

"This product family addresses the performance and scalability requirements of high-end customers and also brings to the mid-range market storage technologies that were previously available only in high end systems for large enterprises. This revolution does a phenomenal job of expanding the range of clients we can serve using IBM TotalStorage products," notes Alain Azagury, manager of Storage and Systems Technologies at the IBM Haifa Labs. With this new product, IBM is offering clients the technology in a package that is suitable for the mid-range market, both in terms of price and in terms of capability. It also allows customers to mix-and-match high-end and mid-range storage controllers without breaking compatibility.

Ultra dense enterprise storage breakthrough
IBM's TotalStorage DS8000 series - a high-performance, high-capacity disk system that uses POWER5 microprocessors and Virtualization Engine technology - provides up to six times the throughput of the company's previous generation enterprise storage system, the IBM TotalStorage Enterprise Storage System 800 (Shark).

The system's advanced copy functions, provided by the IBM Haifa Research Lab, represent a line-up of innovative technologies that IBM provides to help address customers' top priorities in business continuity - high availability, continuous operations and disaster recovery.

Delivering the industry's first real implementation of storage system logical partitioning (LPAR), the refrigerator-size DS8000 series can be used as a single, large storage system or as multiple, totally independent and isolated storage systems.

By running multiple applications and images within the same storage systems, clients can cut their expenses through consolidation, which means less data center floor space, and reduced power and cooling requirements.
The DS8000 series supports major server platforms, including IBM z/OS, z/VM, OS/400, i5/OS and AIX operating systems in addition to Linux, HP-UX, Sun SOLARIS, Novell Netware and Windows environments.

And because many disk storage limitations have been pushed aside by the DS8000, many of the old boundaries for logical volumes, devices, paths and logical subsystems no longer apply. In fact, the system's architecture can address more than 96 petabytes (see sidebar) of data. And like the IBM servers it supports, the DS8000 can use the Standby Capacity on Demand option, which lets clients access extra capacity when the need arises.
