Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.
Embodiment one：
As shown in figure 1, a kind of server eeprom ass address programmings method of the present invention, comprises the following steps：
S1. system transmitting order to lower levels, expander chips are to the Parameter analysis of electrochemical that issues；
S2. whether inspection parameter is legal, if illegal direct end operation, and step S3 is performed if legal；
S3. judge it is to read eeprom or to write eeprom according to parameter, if reading eeprom, then obtain product type, and according to
Product type obtains product parameters, and end operation after data is read from eeprom according to product parameters；If writing eeprom,
Product type is then obtained, and product parameters are obtained according to product type, and is write out according to product parameters from eeprom after data
End operation.
Product parameters in step S3 include iic, Bus number, device address.
Step S1 includes：At the command-line prompt interface of Linux system, transmitting order to lower levels, by SCSI protocol by parameter
It is sent to expander, expander is to the Parameter analysis of electrochemical that issues.
Step S1 specifically also includes：System transmitting order to lower levels, uses sg3_utils instruments, is accessed by scsi command
Expander chips send data to expander chips, and expander chips are parsed to parameter.
Specifically, in step S1, system issues 88 integers and a Read-write Catrol order by sg3_utils instruments
Give expander chips.
Whether inspection parameter is legal in step S2 is specially：Whether the data for examining expander chips to receive are 88
Position data.
In step S3, if in the case of writing eeprom, expander chip iic agreements directly carry out SAS to eeporm
Address programming.
Sas addresses are 88 integers, are generally showed with 16 systems, 0XFF, 0XFF, 0XFF, 0XFF,
0XFF, 0XFF, 0XFF, 0XFF.Programming SAS addresses need to install sg3_utils instruments, this instrument first in Linux system
It is a linux kit, for directly sending data to equipment using scsi command sets access equipment.Issued by this instrument
Expander chips are given in 88 integers and a Read-write Catrol order.Then chip judges whether data are legal, i.e. judgement is
No is 88 data, and then is written and read operation, or returns to error code.
As shown in figure 1, first at the command-line prompt interface of Linux system, transmitting order to lower levels will be joined by SCSI protocol
Number is sent to expander, and expander judges whether parameter is legal to the Parameter analysis of electrochemical issued, if parameter is illegal directly
Terminate, in system interface misprint prompting, if legal judge to read or write again, then according to the iic for above parsing acquisition
Bus address does read or write by iic agreements with device address to eeprom.
Embodiment two：
As shown in Fig. 2 the present invention a kind of server eeprom ass address programmings system, including main cabinet, extension cabinet,
Expander chips, eeprom, HBA card, expander chips are divided into main cabinet expander chips and extension cabinet expander cores
Piece, main cabinet is connected by HBA cards with main cabinet expander chips, and main cabinet expander chips at least cascade primary expansion cabinet
Expander chips, extension cabinet is connected with extension cabinet expander chips, extension cabinet expander chips connection eeprom and from
SAS addresses are read in eeprom.
Connected between expander chips by SAS cables.Expander chips are connected by iic agreements with eeprom.
A HBA card is can be inserted on the main cabinet of server system, it is connected by SAS cables with expander, and main cabinet is logical
One or more levels extension cabinet, which can often be cascaded, increases its memory space, and main cabinet will recognize and find these extension cabinet nodes in systems
It is accomplished by by recognizing that them are distinguished in different SAS addresses, and these SAS addresses generally hang over expander by iic buses
On, expander reads SAS addresses by iic agreements from eeprom.
Patent of the present invention discloses a kind of method of the programming SAS addresses into eeprom；Directly in system transmitting order to lower levels, use
Data are transmitted to expander chips, chip is parsed to parameter, and passes through iic by sg3_utils instruments by SCSI protocol
Agreement directly carries out SAS address programmings to eeporm, it is not necessary to more simple by the serial ports instrument programming of serial ports external computer
Just, resource is saved, and with higher reliability.
Eeprom:Electrically Erasable Programmable Read-Only Memory, it is a kind of non-easy
The internal memory for the property lost；
Expander：Store the firmware of operation in extension cabinet；
HBA：Host bus adapter, host bus adaptor, be one between server and storage device provide input/it is defeated
Go out the circuit board and/or integrated circuit adapter of (I/O) processing and physical connection；
iic：Inter-Integrated Circuit, IC bus；
SCSI：Small Computer System Interface, one kind is used for system-level between computer and smart machine connect
The independent processor standard of mouth.
Above content is to combine specific preferred embodiment further description made for the present invention, it is impossible to assert
The specific implementation of the present invention is confined to these explanations.For general technical staff of the technical field of the invention,
On the premise of not departing from present inventive concept, some simple deduction or replace can also be made, should all be considered as belonging to the present invention's
Protection domain.
