IBM Systems Software: Availability


Today’s market is far more sensitive to service interruptions than it once was. Even brief periods of downtime can cost an organization thousands or even millions of dollars. From the point of view of users and customers, the source of the outage is irrelevant. What matters is that the service is unavailable. The gold standard is continuous, uninterrupted service, no matter what.

Maintaining the highest levels of availability requires not only highly reliable hardware, but robust, fault-tolerant network, system, application and process architectures, as well as automated management that can react immediately and find a way to circumvent any outage, planned or unplanned.

Ensuring business continuity also relies on a secure enterprise. In the face of multiple emerging and evolving security challenges, businesses need to meet highly dynamic regulatory and compliance demands. IBM Systems Software security solutions are designed to enable organizations to achieve end-to-end security in support of business goals. They can help drive innovation and reduce organizational costs, protect against internal and external threats, as well as address operational requirements driven by compliance measures.



The IBM XIV® Storage System is a high-end, next-generation, standalone, open storage system based on a grid architecture. The system can support up to 180 disks, each with a capacity of one terabyte. Its components are standard units based on Intel® technology and Linux®, connected in an any-to-any manner to provide extreme redundancy of all key components, ease of scalability and non-disruptive component replacement.
