LOCLAN between guest systems

Connections between the local X2000 and the local BS2000 via TCP/IP can be used by
means of LOCLAN. This connection is emulated by X2000. If LOCLAN is used, the packet
size may be up to 64 kbytes.
Under VM2000 this connection also allows a rapid LAN connection between the guest
systems and the monitor system via TCP/IP. In principle the connection between the guest
system and monitor system can also be made via a ZASLAN device, but here the packet
size is limited to the CSMA-CD process (Ethernet: 1500 bytes; Jumbo Frames: 9000 bytes).
Application scenarios for LOCLAN between guest systems
File transfer between guest systems
RFA connection between guest systems
XCS cluster or CCS cluster of guest systems
Configuration for LOCLAN usage
The following an example of the entire configuration for an SX server with VM2000:
LOCLAN-IP address Solaris page: 192.168.138.12 (default)
The following IP addresses are used for generating the LOCLAN devices
Y0, Y1 for VM1:
Y4, Y5 for VM2:
The names LOCVM1 and LOCVM2 are assigned for the names of the guest systems via the
LOCLAN connection, unlike the names TESTVM1 and TESTVM2 used for ZASLAN configu-
ration. No further details are given here of the ZASLAN configuration.
Conditions:
Configuration in PRIMEPOWER ServerView
– For BS2000, LOCLAN devices must be configured in X2000 (via BS2000 LAN Ports ->
Create).
– A pair of devices (Xn and X(n+1)) must be generated as the LOCLAN device for each
guest system (the LOCLAN devices Y0 and Y1 are pre-generated for the monitor
system).
– When configuring in X200 the HSI LOCLAN and the mnemotechical device names MN
Xn and X(n+1) of the devices must be entered in the input mask.
– The IP addresses selected must belong to the same local network.
