Remote Mirroring
Business Continuity through Flexible Mirroring!IBM XIV supports business continuity through asynchronous and synchronous mirroring, in support of disaster recovery and remote backup solutions. Its mirroring options cover a broad spectrum of customer replication needs, including support for virtually unlimited distances between sites.
XIV mirroring can be issued automatically, based on user-configurable schedules, or manually, using dedicated commands, or both.
The flexibility and power of XIV asynchronous mirroring is delivered through the XIV system's familiar and easy-to-use user interface, streamlining day-to-day mirroring-related operations.
The XIV system offers mirroring with broad support:
- Asynchronous and synchronous mirroring
- Volume-level and consistency group-level replication, supporting relationships with up to 16 target XIV systems
- Flexible mirroring options that help reduce costs typically associated with replication
- Mirroring of volumes and/or consistency groups
- Flexible replication through independent Recovery Point Objectives (RPOs) and intervals between asynchronous mirrors:
- Independent of mirroring schedules, RPOs can range from 30 seconds to 24 hours, and intervals can range from 20 seconds to 12 hours
- Facilitates flexible planning and priority setting based on business needs
- Bidirectional mirroring
- FC and iSCSI-based mirroring, with the mirroring protocol agnostic to the host protocol (mirroring via iSCSI volumes served by FC and vice versa)
