Maintenance Architecture
Maintenance Architecture
This simplified illustration shows the two elements of the maintenance architecture plus
the OSM maintenance console applications:
As this illustration shows, the OSM console connects to a closed and private service
LAN, connecting the IOAM via a maintenance switch (a ProCurve 2524).
Other hardware modules contain at least one microprocessor and firmware that
performs maintenance functions for their local logic:
•
Blade element
•
Fibre Channel disk module (FCDM)
The ServerNet fabrics, rather than the dedicated service LAN, provide maintenance
interconnection to the OSM console for these modules.
