StorageTek Volume Copy –Target Volume• Selection > May be a standard volume, base volume of a disabled or failed snapshot, replication primary > May reside in a different vdisk to the source volume > Must be at least the same capacity as the source volume• Identical to the source volume after the copy completes• As long as copy relationship is maintained > Target copy can be set to read-only > “Re-copy” command uses same source/target Sun Confidential: Internal Only
  55. 55. Remote Volume Replication• Storage-based solution• Fibre-channel• Consumes one FC port per controller• Synchronous & asynchronous write mode – Asynchronous write order consistency – Dynamic write mode switching• Adjustable replication I/O priority• Fully integrated with StorEdge Configuration Service – Wizard based setup• DRM will be supported using SMIS 1.1 provider Sun Confidential: Internal Only
  56. 56. Replication Rules● Mirroring relationship is on a volume basis ● At most one replication relationship per volume● Primary and secondary volumes must be standard volumes● An array may have up to 32 replication relationships (primary or secondary)● A minimum of 2 arrays are required● Both primary and secondary volumes must be owned by the same controller in each storage array● Secondary volumes are read-only Sun Confidential: Internal Only
  57. 57. StorageTek 6140 Array - TechnicalSummary– New 4 gigabits-per-second improves time to data access and is backward and forward compatible– Same high-availability hardware as in previous generations– Same open SMI/S management software as in previous generations– Same enterprise-level replication, snapshot, and volume copy– Common management software across the StrorageTek 6000 family– Data-in-place upgradeability preserves investment Sun Confidential: Internal Only
