NS0-155 Exam Dumps : Data ONTAP 7-Mode Administrator

The rules for the selection of disks or array LUNs, for using as mirrored aggregates, are as follows:

Disks or array LUNs selected for each plex must be in different pools.

The same number of disks or array LUNs must be in both the plexes.

Disks are selected first on the basis of equivalent bytes per sector (bps) size, then on the basis of the size of the disk.

If there is no equivalent-sized disk, Data ONTAP uses a larger-capacity disk, and limits the size to make it identically sized.

Data ONTAP names the plexes of the mirrored aggregate.

ifconfig - Configures network interface parameters.

The maximum cable length supported for 2Gbps is 500m, the same as the max cable length between a NetApp storage system and a FC switch.

Stretch MetroCluster (sometimes referred to as nonswitched) is simply an active-active configuration that can extend up to 500m depending on speed and cable type. It also includes synchronous mirroring (SyncMirror®) and the ability to do a site failover with a single command. See Figure 2. Additional resiliency can be provided through the use of multipathing.
