San And Network Setup - IBM TotalStorage DS300 Best Practices Manual

All management interfaces of the various components are connected into their
own management network. This is good practice and allows access restrictions
to those persons who need access and restricts it from those who do not. When
using an IBM BladeCenter server to connect to a TotalStorage DS400 the
separate management network is a requirement to prevent network problems.
