CERN History (cont'd) 2007 serial console for ~5000 hosts IPMI power control for ~900 most future deliveries to use IPMI console, power (ACPI!), reset, SysRq Andras Horvath, CERN IT FIO Large-Scale Remote Management via IPMI 6 HEPiX 2007 fall meeting
Free Extras? Orderly (ACPI) emergency shutdown Switch off unneeded capacity Bootup in service order ... Andras Horvath, CERN IT FIO Large-Scale Remote Management via IPMI 7 HEPiX 2007 fall meeting
Monitoring via IPMI Available remotely... ...but we do this in-band What we monitor: thermal and voltage alarms failed PSUs (PSU support required) ECC errors, PCI parity errors Andras Horvath, CERN IT FIO Large-Scale Remote Management via IPMI 8 HEPiX 2007 fall meeting
IPMI tips, tricks, magic Add-on card (BMC): motherboard support req'd Don't believe the vendors: TEST some blades have IPMI within the chassis only What to look for: IPMI 2.0 – encrypted authentication (no 1.5 please) RMCP+ – encrypted wire transfer (for console) Physical interface shared with host or separate? Management firmware, access control, own IP+MAC addresses ... Andras Horvath, CERN IT FIO Large-Scale Remote Management via IPMI 9 HEPiX 2007 fall meeting
Integration iCow: wrapper for consoles also integrates XEN VM consoles solves logging, keeps user interface SysRq (Break) different Password management per-host generated random passwords user interface for power control Power control: could integrate with VM ”virtual power button”?
