1 Overview This disk array is part of the HP StorageWorks XP Disk Array family of products, which provide reliable and secure data storage and protection. These disk arrays also support multiple operating systems, platforms, and RAID groups. Advantages include: • Continuous data availability • Nondisruptive service and upgrades • Connectivity • Scalability • Data integrity and high availability Continuous data availability The HP StorageWorks Disk Array XP family includes the first RAID disk arrays to provide truly continuous data availability. XP disk arrays are designed for nonstop operation and continuous access to all user data. The following features ensure continuous data availability: • No single point of component failure, which enables uninterrupted access to data • Component and function redundancy, providing full fault tolerance for disk array microprocessors, control storage, cache, control and data buses, power supplies, and cooling fans • Can sustain multiple component failures and still continue to provide full access to stored data Note that although access to data is not compromised, the failure of a key component can cause a temporary reduction in disk array performance.
