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

The pktt command controls a simple on-filer packet tracing facility. Packets can be captured into a trace buffer then dumped to a file, or the captured data can be logged to a file. The data is stored in "tcpdump" format, and can be directly viewed with tcpdump, ethereal, and perhaps other viewers. The output can also be converted using the editcap(1) program to a variety of other formats, including Sniffer, NetMon, and snoop.

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.
