Feature Benefits
Distributed, massively parallelled architecture 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. Includes redundancy of all system components at hardware and software levels, including:

  • UPS protection of disk, cache, and electronics, redundant power supply and fans
  • Concurrent multi-path host connectivity
  • Remote mirroring at virtually unlimited distances
  • Non-disruptive code load
  • Proactive error detection and self-healing
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 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. Instant space reclamation is also enabled for supported applications which offer thin reclamation.
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 charge)
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
