For the DS6000, it is possible to install a second network interface card within the DS Storage Manager PC. This would allow you to connect it to two separate switches for improved redundancy.

ESS CLI co-existence

If co-existence with the ESS CS CLI is required, then both the DS CLI and the ESS CLI will have to be installed on the same open systems host, as shown in Figure 11-4 on page 238. Each CLI installs into a separate directory. Depending on how the scripts are written, ESS CLI and DS CLI commands could be issued in the same script.
