A second MU (in case of SU /390) is automatically assigned the addresses 192.168.139.x.
If address conflicts occur, the Customer Support can configure other address ranges.
BRGLAN (only SU x86)
A BRGLAN connection connects BS2000 with an internal virtual switch and enables a LAN
connection to the other virtual machines (= Xen Linux or Windows guest systems) which
are also connected to the same virtual switch.
A BRGLAN connection is required to implement one of the following connections:
– The Native BS2000 system for the XenVMs on the same virtual switch
– BS2000 VMs for XenVMs on the same virtual switch
I
If only BS2000 VMs communicate with each other, LOCLAN connections
should be used.
The BRGLAN connection is a protected internal connection in the Server Unit which is
implemented in the software and thus does not occupy any slots.
With BRGLAN the packet size can be up to 1500 bytes.
An internal virtual switch is configured using the SE Manager. A separate BRGLAN
connection is configured in X2000 for each VM with a BS2000 guest system. The
associated devices are assigned to the relevant VM.
I
The BRGLAN connection requires that at least one virtual switch exists. Virtual
switches can be configured only in conjunction with the operation of XenVMs, i.e. a
XenVM license must exist. For details, see
“Integration of the XenVM guest
systems into the LAN (only SU x86)” on page 39 .
BRGLAN connections are virtual network connections and are therefore not displayed in
the physical LAN structure (see
figure 2 ).
