SyncMirror is a feature of Data OnTap used to mirror data to two separate aggregates. It allows for real-time mirroring of data to matching aggregates physically connected to the same storage system.

SyncMirror provides for synchronous mirroring of data, implemented at the RAID level. You can use SyncMirror to create aggregates that consist of two copies of the same WAFL file system. The two copies, known as plexes, are simultaneously updated. Therefore, the copies are always identical. The two plexes are directly connected to the same system.

The following provides information about the activities of SyncMirror:

SyncMirror can be used to mirror aggregates and traditional volumes. (A traditional volume is essentially an aggregate with a single volume that spans the entire aggregate.)

SyncMirror cannot be used to mirror FlexVol volumes. However, FlexVol volumes can be mirrored as part of an aggregate.

SyncMirror is different from synchronous SnapMirror.

From the article:

"If you reduce the Fractional Reservation to 0, you need to make sure the rate of change is within the volume size, or you need to make sure the volume can auto-grow when required or even snap auto-delete to reduce the reserved blocks and free up space (although I am not a huge fan of snap auto-delete for various reasons)."

Flash Cache is a controller-attached PCIe intelligent caching solution.

Flash Accel is a host-attached caching solution.

Flash Pool utilizes SSDs to enhance performance of disk aggregates (implicitly not controller-wide).

Flash Disk and Flash IO are ambiguous terms.
