Maintenance Architecture Overview
Maintenance Architecture Overview
This simplified illustration shows the three elements of the maintenance architecture
plus the OSM maintenance console applications:
As this illustration shows, the OSM console connects to a closed and private
maintenance LAN, connecting these modules together via a maintenance switch (a
ProCurve 2524):
•
Processor switch (p-switch)
•
I/O adapter module (IOAM)
Other hardware modules contain at least one microprocessor and firmware that
performs maintenance functions for their local logic:
•
Slice
•
Logical synchronization unit (LSU)
•
Disk drive enclosure
The ServerNet fabrics, rather than the maintenance LAN, provide maintenance
interconnection to the OSM console for these modules.
