High Performance. Full exploitation of system resources including disks, CPUs, and switches combined with unique caching algorithms translates into excellent performance.
Active-Active with N + 1 redundancy of all system components
High Reliability. Systems components are protected in an N+1 active-active design to help ensure the highest levels of reliability and availability.
Rapid self healing
Reduced risk of impact from disk failure. The system’s exceptionally short rebuild process allows a 1 TB disk drive to be re-built in 30 minutes or less, helping to reduce the chance of a second disk failure during the critical time of the rebuild process.
Snapshots
Near-instantaneous snapshots. The system’s innovative architecture enables snapshot copies of data to be created and made available in sub-second time. Minimal capacity overhead. Snapshot copies are differential and require capacity only to store changes in data. Up to differential 16,000 snapshots. A true solution for multi-generation logical backup, with virtually no impact to system performance.
Remote mirroring
Protection against site failure. Asynchronous (planned for availability later in 2009) and synchronous remote mirroring provides protection against primary site outages, disasters and site failures.
Thin provisioning
Reduce storage costs. Thin provisioning allows logical volumes to exceed physical capacity, while the latter only need be large enough to contain the data actually written. This flexibility can offer dramatic savings in storage, power, and space costs. Simplified provisioning and space reclamation. can simplify the management of capacity allocation for application workloads. Using XIV management tools, administrators can easily zero out space no longer in use. The system then releases that space into the general pool, allowing its reuse.
Data migration
Allows the migration of volumes from current-generation systems to the IBM XIV Storage System, copying the information while applications are online.
Native concurrent multi path support
Optimized, reliable integration with the host operating system. Cost-effective connectivity. No delays awaiting 3rd party device drivers.
Storage infrastructure optimization
IBM Tivoli Storage Productivity Center (TPC 4.1) support for discovery, asset and utilization management, historical trending and alerting within XIV environments. Tivoli Storage Manager (TSM) Copy services 6 for Advanced Copy Services enhances copy, backup, and restore operations for Windows and AIX applications.
