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

 

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

QUESTION 127

A.

The file is the basic unit for SnapVault backup destination.

B.

The qtree is the basic unit for SnapVault backup destination.

C.

The volume is the basic unit of SnapVault backup destination.

Explanation:

https://library.netapp.com/ecmdocs/ECMP1196991/html/GUID-06C70D3B-9A06-4D20-B140-EB147B941BDA.html

 

The data structures that are backed up and restored through SnapVault depend on the primary system.

On systems running Data ONTAP, the qtree is the basic unit of SnapVault backup and restore.

SnapVault backs up specified qtrees on the primary system to associated qtrees on the SnapVaultsecondary system. If necessary, data is restored from the secondary qtrees back to their associated primaryqtrees.

On open systems storage platforms, the directory is the basic unit of Sn
apVault backup. SnapVault backs upspecified directories from the native system to specified qtrees in the SnapVault secondary system.

 

If necessary SnapVault can restore an entire directory or a specified file to the open systems platform.

The destination system uses a slightly more disk space and directories than the source system.
