Table 2: High-Availability Features: PRIMEPOWER XA Enterprise Servers (900,1500
and 2500)
Hot-Plug System
Boards
Yes
Hot-Sparing of COD
CPUs
Supported in ESCoD
Failure Prediction
Dynamic Degradation: when threshold of intermittent errors is reached, Solaris can
take processor offline
Memory Protection
and Recovery
ECC on memory and all data paths; distributed memory modules and chip-kill
functionality; soft memory scrubbing
Hot-Pluggable Disks
Yes
Hot-Plug PCI I/O
Yes (hot-plug PCI cards are supported; PCI boards can also be hot-plugged as on
the 900 and 1500 [they’re part of the system board])

Disks
Supported in Solaris
I/O Multipathing
Yes (Internet Protocol [IP] and I/O failover supported in Solaris)
Deconfiguration of
Failed Components
at Reboot
All Models: Yes (CPUs, memory); if component fails, system deactivates it at the
electrical level and deconfigures it during reboot
2500: Redundant clocks and crossbars mean that system can restart configured
with the remaining crossbar or clock
Auto Reboot and OS
