Enabling Instant Snapshots

The Storage Systems Integration (SSI) component of the EXTENDED BUFFER MANAGER (XBM) product, when used with supported BMC utilities, creates Instant Snapshots by exploiting the capabilities of intelligent storage devices.

These Instant Snapshots are physical data copies that are almost instantaneous because they require no I/O. In addition to a near-instantaneous copy process, Instant Snapshots offer a near-instant restore phase during database recovery. The following figure shows an example of this process:

This section describes how to enable XBM to process Instant Snapshots.

An Instant Snapshot requires specific additional software and hardware to process the snapshot. In addition to XBM, you must have one of the supported BMC utilities and supported intelligent hardware devices.

This section describes the software and hardware required to do an Instant Snapshot. It also describes the way that XBM uses these utilities and storage devices to process the Instant Snapshot.
