Intelligent-platform management interface system and manner of execution thereof
Technical field
But the present invention relates to the advanced intelligent platform management interface system and the manner of execution thereof of many information processings of a kind of tool and planning performance, relate in particular to a kind of intelligent-platform management interface system and manner of execution thereof that is used for server admin.
Background technology
As everyone knows, system operator was for being positioned at long-range all types of servers such as faults such as telecommunications room or computer installation in the past, particularly critical server such as isp server fault are stopped, just must go to the locality to keep in repair or the fault eliminating in person, so too in labor intensive cost and time cost.For solving this kind problem, develop out gradually about the administrative skill of remote server, be a kind of technology that is referred to as IPMI (IPMI).
This kind IPMI (IPMI) mainly comprises: a hardware frame, promptly one has baseboard management controller (Baseboard Management Controller, BMC) microcontroller, and interior firmware (Firmware) framework of this baseboard management controller of embedding, it in fact is a kind of server admin subsystem (Server Management Subsystem), but independently operate on this hardware of server such as central processing unit (CPU), substantially import out system (BIOS) and software such as operating system (OS), outside the system management software (SMS), with the interface between control system management software and the platform hardware management, particularly when central processing unit (CPU) at aforementioned server, when importing out system (BIOS) and operating system (OS) inefficacy (Fail) substantially.
The BMC microcontroller of most IPMI (IPMI) itself is promptly integrated the A/D converter that a monitoring voltage is used, the fan speed counter, IO that inductor is used and bus etc., so check out the central processing unit (CPU) of this server when one of this IPMI (IPMI) monitors (Watchdog) timer, substantially import out system (BIOS), when operating system (OS) or application program meet accident fault, can filter the indication queueing problem of (PEF) queueing problem or reception operating terminal by the platform events that this IPMI (IPMI) provides self.In addition, this IPMI (IPMI) can initiatively provide the software/hardware that comprises server system state supervision, event log recorder, restart system control function, incident produced warning, and automatic system control functions such as (as outages) automatically, for example, the BMC microcontroller of IPMI utilizes a kind of I
2The C digital sensor is obtained measurement result to host computer system with poll (Polling) form, with system voltage, temperature and the fan speed change of monitoring this long-range host computer system, judging whether this monitoring data exceeds outside the default scope, and transmit I with a kind of Intelligent Platform Management Bus (IPMB)
2The sense data of C (being a kind of IPMIMessage) is sent or by SMBus interface and host computer system communication.And, in case can be stored in the event logger (SEL) when the incident of system exception is arranged, and by this platform events filter (PEF) look for one with the reaction action of " this anomalous event " coupling, as carry out outage, again connect electricity, restart and send out/send action such as warning.
In addition, this IPMI (IPMI) can make things convenient for long-range operating terminal to meet RMCP UDP/IP protocol of I PMI message packet via a LAN (LAN) transmission as tool, or via the serial signal of serial modem such as UART interface protocol, to carry out telemonitoring or to control this server, obtain above-mentioned monitoring data, can carry out fault so that matters of aggravation is produced immediately and get rid of.When aforementioned server temperature seriously overruns, except that being got off, data recording supplies outside the inquiry in the future, promptly this IPMI (IPMI) independence is got rid of, similarly be to improve fan speed immediately to increase radiating effect, and send a network by LAN (LAN) and warn, warn promptly in the SNMP Traps mode in platform events layer (PET) form, or with a serial modulator-demodular unit, be sent to long-range operating terminal computing machine.This operating terminal computing machine, the BMC controller of host computer system or IPMI (IPMI) can be by fixing several different passages (Channels) as Intelligent Platform Management Bus (IPMB), Keyboard Control interface (KCS), intelligent machine package reason bus (ICMB), firmware handle and the response of an IPMI (IPMI) channel information (Channel Message) for this IPMI (IPMI) received/sent out to UART Universal Asynchronous Receiver Transmitter (UART) or LAN (LAN).
Be noted that this intelligent-platform management interface system is can't direct access one sensing apparatus such as I
2The data of C sensor hardware, but need by a sensor management unit such as Management Controller produce a sensor order as " Get Sensor Reading " to obtain aforementioned data.
Yet there are following several shortcomings in the firmware design and the imperfection of this IPMI (IPMI) at present:
(1) each IPMI information is in the process of each module of passing through this firmware or unit, each module or unit self all need dispose an exclusive region memory (Local Memory) to duplicate the IPMI information of passing through, just can proceed to transmit (Passing), formation (Queue), use (Usage) or (Implementing) each IPMI information of execution, so not only cause higher internal memory cost, also because of will constantly reading and duplicate IPMI information in each step, so make the execution time of total system elongated, cause the execution usefulness variation of such IPMI (IPMI).
(2) performance element of known smart platform management interface (IPMI) firmware only can be handled an IPMI information each time, all the other IPMI information only can queue to wait for response next time, therefore make the execution usefulness of this type of IPMI (IPMI) more not good.
(3) many unit draw because of mutual in known smart platform management interface (IPMI) firmware, can't replace easily, particularly when the operator need change or increase and decrease difference in functionality, unless general frame is write again, therefore otherwise can't realize change, for user not tool amplification property and the property planned.
(4) known smart platform management interface (IPMI) firmware need read sensed event in the Electrically Erasable Read Only Memory (EEPROM) in the sensing apparatus by a sensing administrative unit such as Management Controller; Yet, access speed in this Electrically Erasable Read Only Memory (EEPROM) is extremely slow, if have a lot of IPMI information enter always with etc. when pending, this Electrically Erasable Read Only Memory (EEPROM) can busyly always cause line congestion, particularly when this Electrically Erasable Read Only Memory (EEPROM) be when sharing same data bus (Data bus) with other device, more can factor to cause this system to carry out according to conflict slow.
(5) known smart platform management interface (IPMI) firmware can't be automatically cooperates with the hardware environment of too much different manufacturers such as BMC controller or with the operating system (OS) of different manufacturers.
