WAFL

FlexVol volume vs Traditional volume

FlexCache,類似VNX FastCache

FlexClone,類似HDS Copy-On-Write

FlexClone volumes are writable, point-in-time copies of a parent FlexVol volume. FlexClone

volumes are space-efficient because they share the same data blocks with their parent FlexVol

volumes for common data. The Snapshot copy used to create a FlexClone volume is also shared with

the parent volume.

You can clone an existing FlexClone volume to create another FlexClone volume.

You can also

You can also split a FlexClone volume from its parent volume. As a result, the FlexClone volume

becomes an independent FlexVol volume with its own disk space, instead of sharing disk space with

its parent.

4、高可用

Standard HA

provide high availability by pairing two controllers so that one can serve

data for the other in case of controller failure or other unexpected events

Mirrored HA pairs(或稱作SyncMirror)

provide high availability through failover, just as standard HA pairs do.

Additionally, mirrored HA pairs maintain two complete copies of all mirrored data. These copies are

called plexes and are continually and synchronously updated every time Data ONTAP writes to a

mirrored aggregate. The plexes can be physically separated to protect against the loss of one set of

disks or array LUNs.

MetroCluster(Stretch、fabric-attached)

provide data mirroring and the additional ability to initiate a failover if an entire site becomes lost or

unavailable.The stretch MetroCluster employs SyncMirror to build a system that can continue to serve data even

after complete loss of one of the sites. Data consistency is retained, even when the data is contained in more than

one aggregate.Like mirrored HA pairs, stretch MetroCluster configurations contain two complete copies of the

specified data volumes or file systems that you indicated as being mirrored volumes or file systems

in your HA pair. These copies are called plexes and are continually and synchronously updated every

time Data ONTAP writes data to the disks. Plexes are physically separated from each other across

different groupings of disks or array LUNs.
