Embodiment
Fig. 1 is referred to, Fig. 1 is the mainboard configuration diagram of storage server in existing realization.
As shown in figure 1, in the mainboard framework of storage server, business I/O port, CPU, IOH (Input are generally included
Output Hub, input and output hub), internal memory, SAS controller, SAS expander and RAID array.
Wherein, CPU is responsible for the work that operating system, RAID algorithm and all business processings calculate correlation.IOH is support
CPU chipset, it is responsible for providing some low-speed interfaces；For example, management network port, button and serial ports etc..Internal memory, for being
System provides larger capacity and caching faster；For example, the internal memory can be the internal memory of DDR3 specifications.SAS controller, it is responsible for
SAS protocol conversion, and the processing of associated storage instruction are provided.SAS expander, it is responsible for expanding the port number of SAS controller, phase
When in an interchanger.RAID array, for the array with redundant ability that is made up of independent disk, disk array can be by
Many less expensive disks of price, a capacity being combined into huge disk group, so as to lift the effect of whole disk system
Rate；For example, RAID array can be SATA (the Serial Advanced Technology by compatible SAS protocol
Attachment, Serial Advanced Technology Attachment) hard disk or SAS hard disks.
In above-mentioned mainboard framework, the read-write operation of data is mainly responsible for processing by CPU.
For CPU when carrying out the read operation of data, read I O request enters CPU from business I/O port, and CPU is asked receiving reading IO
After asking, the read I O request is buffered in internal memory first, then CPU reads buffered read I O request from internal memory, then will
The read I O request is handed down to disk array by SAS controller, then by SAS expander.
After disk array receives the read I O request that CPU is issued, the disk of disk array starts to rotate, and tracking, then performs
After read operation corresponding with the read I O request, the data read are cached to by SAS controller, then by SAS expander
In internal memory, then the data of caching are read by CPU from internal memory, the originating end master to the read I O request is sent to by business I/O port
Machine.
For CPU when carrying out the write operation of data, write IO request enters CPU from business I/O port, and CPU is asked receiving this and write IO
After asking, first by the write IO request and the data buffer storage of this secondary write-in in internal memory, then CPU is read from internal memory
The write IO request of caching, then the write IO request is handed down to disk array by SAS controller, then by SAS expander.
After disk array receives the write IO request that CPU is issued, the disk of disk array starts to rotate, and tracking, then performs
After write operation corresponding with the write IO request writes the data for being buffered in the secondary write-in of this in internal memory successfully, a write-in is returned
Successful notice message, the notice message are cached in internal memory by SAS controller, then by SAS expander, then by CPU from
The successful notice message of the write-in of caching is read in internal memory, the originating end master to write IO request is sent to by business I/O port
Machine.
It can be seen that in the existing mainboard framework of storage server, the disk of disk array receive IO that CPU issues please
It is generally long between magnetic head tracking time and rotation delay when seeking progress reading and writing data, if CPU frequently accesses disk, disk
The most of the time of work is all seeking, and operating efficiency will be very low, necessarily causes whole computing system operation slow, therefore
Disk access is accelerated extremely to be necessary.
In view of this, the application proposes a kind of mainboard framework of new storage server, the mainboard framework include CPU,
Data read-write module, internal memory based on FPGA；The data read-write module based on FPGA takes with the CPU and the storage
The disk array of business device is respectively connected with；The internal memory is connected with the data read-write module based on FPGA.CPU is being carried out
During reading and writing data, the data read-write module based on FPGA receives the read-write I/O request that CPU is issued, and the read-write I/O request is carried out
Read/write address corresponding to parsing acquisition, and judge to get whether the read/write address hits default focus number in the internal memory
According to the allocation index in storehouse；When the read/write address got hits the allocation index in the default hotspot database
When, it is described to be performed locally and the reading based on the hot spot data in the hotspot database based on FPGA data read-write module
Read-write operation corresponding to write IO request.
Due in the mainboard framework, when reading and writing data hit hotspot database corresponding to the read-write I/O request that CPU is initiated
In hot spot data when, will by based on data of the FPGA data read-write module in hotspot database its locally complete with
Read-write operation corresponding to the read-write I/O request, performed without the read-write I/O request is issued into disk array corresponding
Read-write operation, thus can effectively reduce monolithic disk in disk array read-write operation number save disk tracking when
It is long, so as to realize the acceleration of disk access, the access speed of hot spot data is greatly improved, improves storage server
Overall readwrite performance.
The application is described below by specific embodiment and with reference to specific application scenarios.
Fig. 2 is refer to, Fig. 2 is a kind of mainboard framework that the embodiment of the application one provides, applied to storage server.
As shown in Fig. 2 in the mainboard framework, including CPU, based on FPGA (Field Programmable Gate
Array, i.e. field programmable gate array) data read-write module (hereinafter referred to as FPGA), business I/O port, disk array and with
The first internal memory that CPU is connected and the second internal memory being connected with FPGA.Wherein, the FPGA is connected with CPU；The FPGA
It is connected with the disk array of storage server；First internal memory can be the internal memory of DDR3 specifications；Second internal memory can
To be high-capacity flash memory.
What deserves to be explained is FPGA and the disk array of storage server when being attached, can be controlled by SAS with
And SAS expander is connected with disk array, can also by FPGA analog-driven come realize the function of SAS controller with
Disk array directly establishes connection.
Wherein, by FPGA analog-driven be connected to realize that the function of SAS controller is directly established with disk array
This implementation, can effectively shorten data paths of the CPU when carrying out disk access, reduce time delay.
In the mainboard framework, a hot spot data can be pre-set in the second internal memory being connected with the FPGA
Storehouse, it is used in the hotspot database deposit allocation index corresponding to hot spot data and the hot spot data.
When realizing, the hotspot database can be one default for recording hot spot data and allocation index
Cache tables, second internal memory can be the cachings of Large Copacity, and the caching of the wherein Large Copacity can be the common interior of Large Copacity
Deposit or the flash memory of Large Copacity；It is for instance possible to use hundreds of G sizes pass through flash memory caused by cascade system or general
Logical internal memory.
Wherein, when the caching of above-mentioned Large Copacity is the flash memory of Large Copacity, the characteristic based on flash memory itself, it is ensured that fall
Hot spot data will not be lost after electricity.When the caching of above-mentioned Large Copacity is the common memory of Large Copacity, process performance can be improved,
But, it is necessary to set an independent stand-by power supply for the common memory of the Large Copacity during in order to ensure that hot spot data is not lost.Separately
Outside because the caching of above-mentioned Large Copacity has larger capacity, therefore a large amount of hot spot datas can be cached, so as to increase hot spot data
Access hit rate.
After FPGA is in the read-write I/O request issued by CPU received, the read-write I/O request to receiving can be passed through
Parsed to obtain corresponding read/write address, if the allocation index in the read/write address hit hotspot database parsed
When, FPGA can directly be performed locally corresponding read-write operation based on the hot spot data in the hotspot database, from without
Will the read-write I/O request be issued to disk array to perform corresponding read-write operation.
In this way, due to completing the parsing of read-write I/O request by FPGA to substitute CPU, therefore can share
CPU calculating pressure, so as to greatly improve the access speed of hot spot data, lift the overall read-write of storage server
Performance.
In above-mentioned mainboard framework, the read-write operation of data is still responsible for processing by CPU.
The process for carrying out data reading and writing operation to CPU below is described.
In the mainboard framework, FPGA is used to receive the read-write I/O request that the CPU is issued, and to the read-write I/O request
Carry out read/write address corresponding to parsing acquisition.After corresponding read/write address is got, FPGA, which may determine that, gets the reading
Whether write address hits the allocation index in default hotspot database in the internal memory；When the read/write address life got
Described in allocation index in default hotspot database when, FPGA can be existed based on the hot spot data in the hotspot database
Locally execute read-write operation corresponding with the read-write I/O request.
Specifically, when user initiates a read operation by main frame to storage server, can be sent to storage server
One read I O request, the data that this secondary reading can be included in the I/O request store in the disk array of storage server
LBA (Logical Block Address, logical block addresses) address.Storage server is when receiving read I O request, the reading
I/O request can enter CPU by business I/O port, and the read I O request is buffered in by CPU first after the read I O request is received
In first internal memory.Then CPU reads the buffered read I O request from internal memory again, and the read I O request is handed down into FPGA.
Same reason, can be to storage server when user initiates a write operation by main frame to storage server
A write IO request is sent, the LBA addresses that write data can be included in the I/O request.Storage server writes IO in reception
When request and the data to be write, the write IO request and the data to be write can enter CPU, CPU by business I/O port
After the write IO request and the data to be write is received, first by the write IO request and the data buffer storage to be write
In one internal memory, then CPU reads the buffered write IO request from internal memory again, and the read I O request is handed down into FPGA.
In the mainboard framework, FPGA, can be to receiving after receive the read I O request and write IO request that CPU is issued
Read I O request and write IO request are parsed, then same according to parsing to obtain corresponding reading address and write address
The number pair of address data corresponding with the reading address and write address conduct interviews number statistics；Wherein, the access times of data
The number for the number and write-in read can be included.
For example, after FPGA is by parsing the read I O request that receives or writing IO and get an address first, show
For data corresponding with the address there occurs once reading or writing, FPGA can be that data record corresponding to the address is once visited
Ask；After FPGA is by parsing the read I O request that receives or writing IO and get the address again, show corresponding with the address
Data again there occurs once read or write-access, then FPGA the access times counted can be updated,
The access times of data corresponding to the address are added one, by that analogy.
In this way, FPGA can conduct interviews secondary during the read-write of data to all data read and write
Number statistics.Meanwhile can also be by by the access times counted and default threshold for the access times that statistics is completed, FPGA
Value is compared to determine that the data which is read and write are hot spot data.
When realizing, FPGA, can be real-time by the access times counted in the statistic processes for conducting interviews number
Compared with default threshold value, when the access times of any data reach default threshold value, then it can determine that the data are
Hot spot data, the data are saved in hotspot database, and the address of the data and the data is established in hotspot database
Corresponding relation between index.Wherein, the default threshold value, can be according to reality in this application without being particularly limited to
Business demand is set
For example, after the read I O request that receives of FPGA parsings gets an address again, now FPGA can should
The access times of data corresponding to address add one, and are simultaneously compared the current access times of the data with default threshold value
Compared with if now the access times of the data reach threshold value, when FPGA is receiving number read of disk array return
According to when, can be saved in using the data as hot spot data in hotspot database, while using the LBA addresses of the data as address
Index the corresponding relation established in hotspot database with the data.Same reason, when the IO that writes that FPGA parsings receive please
Ask after getting an address again, now FPGA can add the access times of data corresponding to the address one, and simultaneously will
The current access times of the data are compared with default threshold value, if now the access times of the data reach threshold value,
The data of this secondary write-in can be saved in hotspot database by FPGA directly as hot spot data, while by the data
LBA addresses are established and the corresponding relation of the data as allocation index in hotspot database.
Certainly, in actual applications, the hot spot data preserved in hotspot database, can also manually be referred to by keeper
It is fixed, in the present embodiment without being particularly limited to；For example, keeper can will be with every a kind of hot spot service phase from disk array
The data of pass are manually copied to hotspot database.
For the hot spot data being stored in hotspot database, the data in FPGA is received for hotspot database again
Read I O request or write IO request when, corresponding read-write operation can be directly completed from hotspot database, without will read
I/O request or write IO request are issued to disk array to carry out corresponding read-write operation.
For example, when realizing, when FPGA receives a read I O request issued by CPU, FPGA first can be to this
Read I O request is parsed to obtain corresponding reading address, and then FPGA can be by the reading address parsed and hotspot database
Allocation index matched successively, to judge whether the reading address hits the allocation index in hot spot data；If the reading
When the allocation index in hot spot data is hit in location, now data corresponding with the reading address are hot spot data, and FPGA can be direct
Read operation corresponding with the read I O request is performed locally, reading and the reading address corresponding data from hotspot database, then
The data read are returned into CPU, then are sent to initiator's main frame of the read I O request by business I/O port by CPU.Certainly,
If the allocation index in the reading address misses hotspot database, then the read I O request is issued to disk array by FPGA,
Sought by the disk on disk array, data are read from the disk of disk array.
When FPGA receives a write IO request issued by CPU, FPGA first can solve to the write IO request
Analyse to obtain corresponding write address, then FPGA can be by the allocation index in the write address and hotspot database that parse successively
Matched, to judge whether the write address hits the allocation index in hot spot data；If the write address hits hot spot data
In allocation index when, now data corresponding with the write address are hot spot data, then this write operation for covering write-in behaviour
Make, FPGA can directly be performed locally write operation corresponding with the write IO request, will be buffered in the sheet in CPU the first internal memory
The data of secondary write-in are saved in hotspot database, and legacy data corresponding with the write address in hot spot data is covered
Renewal.Certainly, if allocation index in the miss hotspot database of the write address, then the write IO request is issued to by FPGA
Disk array, sought by the disk on disk array, the data that will be write are written in the disk of disk array.
It can be seen that in this way, FPGA is when processing is received by the CPU read I O requests issued and write IO request, such as
Allocation index in the address hit hotspot database that fruit parses, then FPGA then need not be by read I O request or write IO request
Disk array is issued to carry out corresponding read-write operation, directly can perform corresponding read-write operation local, so as to
To reduce the read-write number for being directed to disk in disk array, reduce in disk array due to disk arm is mobile and during caused tracking
Between, improve the access speed of hot spot data.
In addition, for the data in hotspot database, FPGA can also be according to default algorithm in hotspot database
Data and allocation index are updated in real time, by sluggish write back data in hotspot database to disk array.Wherein,
For FPGA when the data in hotspot database are updated in real time, used algorithm is in this embodiment without especially limit
It is fixed.
In a kind of algorithm shown in the present embodiment, FPGA can set a default duration, when in hotspot database
Hot spot data be not accessed for a long time, and the duration for continuing not to be accessed reaches the default duration of setting,
So now FPGA then can be by the write back data preserved in hotspot database to disk array, and deletes in hotspot database
Allocation index corresponding to the hot spot data preserved.For example, for the allocation index preserved in hotspot database, FPGA can divide
The time point that the allocation index last time is matched is not recorded, when any allocation index preserved in hotspot database was apart from last time
When the duration at the time point being matched reaches the default duration, show not living enough in this period of the hot spot data
Jump, FPGA can be by the write back data to disk array, and deletes the allocation index of the data in hotspot database.It can be seen that
In this way, it is ensured that the data in hotspot database are active hot spot data in certain period of time.
By above description, the application proposes a kind of mainboard framework of new storage server, in the mainboard framework
Data read-write module, internal memory including CPU, based on FPGA；The data read-write module based on FPGA and the CPU and institute
The disk array for stating storage server is respectively connected with；The internal memory is connected with the data read-write module based on FPGA.
For CPU when carrying out reading and writing data, the data read-write module based on FPGA receives the read-write I/O request that CPU is issued, to the read-write
I/O request carries out read/write address corresponding to parsing acquisition, and judges to get whether the read/write address is hit in the internal memory in advance
If hotspot database in allocation index；When the read/write address got is hit in the default hotspot database
It is described to be performed locally based on FPGA data read-write module based on the hot spot data in the hotspot database during allocation index
Read-write operation corresponding with the read-write I/O request.
Due in the mainboard framework, when reading and writing data hit hotspot database corresponding to the read-write I/O request that CPU is initiated
In hot spot data when, by by based on FPGA data read-write module according to based on the data in the hotspot database at it
Read-write operation corresponding with the read-write I/O request is completed on ground, without the read-write I/O request is issued into disk array to hold
Read-write operation corresponding to row, therefore the read-write operation number of monolithic disk in disk array can be effectively reduced, save disk
Tracking duration, so as to realize the acceleration of disk access, greatly improve the access speed of hot spot data, improve and deposit
Store up the overall readwrite performance of server.
