Not all traffic reduces well
Only compresses traffic between SR units Centralized monitoring could be better SR-20 Sequence Reducer, starts at $2,900. Central Management System (CMS), starts at $5,000. Peribit Networks, (866) Peribit, (408) 330-5600. peribit.com/products/cms.htm |
The SR also has some limited reporting capabilities. It can generate graphs for throughput, data-reduction rates and total data transferred, and display them by application.
Peribit's CMS is primarily for large deployments. I installed a copy of CMS on my LAN segment, and after specifying the registration server's IP, I was given a list of the SRs on the LAN. I could extract from or load software images and configuration files to all my SRs. To test this capability, I extracted the configuration from SR-2 and specified it be loaded on SR-3. The unit rebooted, and a minute later the config was there.
The CMS lets you view traffic reduction stats, though it offers only a graphical representation of how much data is reduced for each tunnel; it doesn't provide hard numbers for the entire network.
