Management Path - Hitachi CB 520H A1 User Manual

Assignments of Virtual NIC to Network Segment are assigned on the Virtual
NIC Assignment Screen. Usable Network Segment IDs are Va, Vb, Vc, Vd.
On the above chart, NIC #0 on LPAR1 (which is assigned to Segment Vc) can
communicate to NIC #1 on LPAR2, but NIC #0 on LPAR1 cannot
communicate to NIC #2 on LPAR2 (because their segments are different).
Virtual NICs on the same Segment can communicate each other.
Note:
• Total throughput of virtual NICs is 3 Gbps per LPAR manager.
Tip:
• Each Virtual NIC on the same Network Segment can communicate each
other.
However Virtual NICs on the different Network Segment cannot
communicate each other.

Management Path

The network path configured for server operation is called "operation path".
The network path configured for management and operation of server and
LPAR manager is called "management path".
Before starting LPAR manager, you must configure a management path to be
used for communication between LPAR manager and the management
module. The scheduling mode must be set to shared mode for the NIC to be
set for the management path.
Also, the IP address of the LPAR manager to be used for the management
paths is called the LP IP address.
The dedicated NIC for the management path is not mounted in CB 500. Thus,
NIC used for LPAR (guest OS) is used in the shared mode. (LPAR manager
