The process of mirroring data between two locations to ensure data availability in the event of a complete data-centre outage.

High-capacity, low-cost-per-gigabyte FC drives for cost-effective storage of less critical or infrequently accessed information. Plug-and-play compatible with existing HP StorageWorks EVA systems.

Part of the capacity of an array that appears to the operating system as a physical disk. Data in a LUN is spread across all disks in an array.

A new class of low-cost disk drives to store data with low performance requirements.

A low-cost disk technology compared to SCSI- or FC-based disks. Ideal for storage of less-critical data that doesn’t require optimum performance or reliability. Available with the HP StorageWorks MSA1500.

A Snapclone starts as a Snapshot, which can immediately be presented to a server for reads and writes. At the time of the creation of the Snapshot, the array controller starts copying data from the virtual disk to the Snapclone virtual disk to create a full, identical copy.

Virtual disk Snapshots are disk-based copies of stored data that reduce backup windows to seconds. A Snapshot only replicates pointers to data – not the actual data itself – meaning they are virtually capacity-free.

Technology that simplifies the complexity of array management and increases flexibility, availability and performance. See page 4 for details.

Next-generation distributed software that creates and manages storage pools with advanced features like dynamic capacity growth and virtually capacity-free Snapshots.
