• Panel control

• Log information management within BladeSymphony 1000 (RC logs, SEL, SVP logs, etc.).

• SVP hot standby configuration control

• Server Conductor (server management software) interaction function. (Including a function for

emulating the PCI-version SVP function.)

• HA monitor (cluster software) interaction function.

• Management interface (SVP console (Telnet/CLI, RS232C/CLI), SNMP)

• Assist function (E-mailing to the maintenance center)

BladeSymphony 1000 implements the functions of the SVP card through software emulation by BMC

and SVP over fast Ethernet and I2C connections, as shown in Figure29.

Base Management Controller (BMC)

One instance of BMC is installed f or each CPU module primarily to take charge of management within

the physical partition (including a single CPU module). Only one instance of SVP is active throughout

the system, managing the entire system in cooperation with BMC. SVP and BMC communicate with

each other via a SVP build-in 100 BASE-TX LAN. In the case of the Intel Itanium Server Blade, a BMC

on the primary CPU module operates as the representative of BMCs present in the partition. This BMC

is referred to as the primary BMC.
