24 IBM System Storage DS3500: Introduction and Implementation Guide
In-band management
The in-band management method uses the I/O path between the host server and the DS3500
to transfer management commands and information.
This method does not use the management Ethernet ports on DS3500 RAID controllers and
does not require a management TCP/IP network. However, it does require a special
access
logical drive
to manage the DS3500 controllers. This means that you cannot configure the
maximum number of logical drives, because one of them is reserved for the access logical
drive. But this is usually not a problem, because virtually all customers will find the maximum
number of logical drives more than sufficient.
An example of in-band management is shown in Figure 2-12. Two host servers are attached
to the DS3500 subsystem with FC cables. They both run SMagent code. The management
workstation runs SMclient code. SMclient communicates with SMagent through Ethernet, and
SMagent communicates with the DS3500 across the FC I/O path.
