User interface has rough edges Vendor Info NEXVU Controller, $19,995; NEXVU Manager, $6,499. NexVu Technologies, (800) 410-1881, (630) 872-5800. www.nexvu.com |
Both the Controller and Manager have status screens displaying a high-level view of the network. The Controller's status screen has an information box for each Manager that contains simple bar graphs, strip charts or pie charts. The graphs or charts display the amount of traffic passing through each node by protocol and the percentage of maximum load the line is carrying. Under the graphs, you'll see the number of active flows, the number of bytes per second flowing on that Manager's network, and the packets per second on the network for each Manager.
Moving your mouse over a graph brings up labels that explain which graph segment correlates to which protocol. You can get to the Manager from the Controller to glean more detail with two mouse clicks. However, this is an error-prone operation in larger networks. The ability to go directly from the Controller status screen to the Manager status screen by clicking on any chart that catches your eye has been promised in the July software release.
You can set the Manager to run up to 19 monitoring programs to watch various aspects of network performance and then report exceptions to the Controller. You also can
configure the Manager to run network-performance reports on a user-selected schedule and send them to the Controller. Reports also can be run on command. NexVu says the Manager stores about a month's worth of data for a typical site, so the network manager can get a good idea of trends and abnormal traffic.
In the beta version I tested, some reports on the menu wouldn't run;
I couldn't get the backup or checkpoint software to work; it wasn't obvious how to access reports that had been run by the scheduler; and root-cause analysis wasn't available. NexVu says these problems should be cleared up in the main release.

AI may force enterprises to rewire parts of their data centers so they are fully optimized to run such workloads. The question is do you use Ethernet or InfiniBand?
