Yes
Supported in ESCoD
Dynamic Degradation: when threshold of intermittent errors is reached, Solaris can
take processor offline
ECC on memory and all data paths; distributed memory modules and chip-kill

Yes
Yes
Yes
Yes
Yes
Optional
Supported in Solaris

electrical level and deconfigures it during reboot
2500: Redundant clocks and crossbars mean that system can restart configured
with the remaining crossbar or clock
Yes
Yes; service processor provides surveillance of system operation
Standard on 1500 and 2500
