The embodiment of the invention provides a kind of method of supplying power to and electric supply installation of storage system, can avoid system when abnormal power-down takes place, and causes controlling the memory buffer store data inside and loses.For the ease of fully understanding to embodiment of the invention technical scheme, make that purpose of the present invention, technical scheme and advantage are clearer, below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is carried out clear, complete description.
Embodiment one:
Please refer to Fig. 1, Fig. 1 is for being arranged on the structural representation of the storage system of the ROC architectural framework on the motherboard circuit in the embodiment of the invention.This storage system mainly comprises: CPU, data cache, control cache, north bridge chips, ASIC, 2068E module, DE4 module, disk, Flash type storer and HOST module;
In the storage system of ROC architectural framework, with data cache and control cache separate management.Wherein, the HOST module connects host side, receives the request of data that the host side user sends; The DE4 module is used for the mutual of request of data and data feedback result between HOST module and the ASIC; The 2068E module is used to realize the conversion of interface shape between disk and the ASIC; CPU directly with control cache and be connected, store OS, the system file relevant among this control cache with the data message index; Data cache links to each other with ASIC.
By with the separating of data cache and CPU, improve the performance of CPU.
Please refer to Fig. 2, Fig. 2 is the electric supply installation structural representation of a kind of storage system of the embodiment of the invention;
This device comprises:
Described motherboard circuit comprises: control cache, data cache and connect the CPU of described control cache, described data cache comprise and read address storage space and write address storage space;
First power module is enabled unit 202, be used for when the externally fed that detects described motherboard circuit is interruption status, enable the electric power source pair of module CPU power supply of described motherboard circuit inside, the system file data unloading relevant with the data message index that makes CPU to control to have stored in the memory buffer read the address storage space to Data Buffer Memory;
Need to prove herein, the data message index is that a class stores the system file data that concerns under subordinate's file and the higher level's file, the path of searching in order to a certain specific data information of record search, have only under the prerequisite of this part system file existence, could correctly find the specific data information among the data cache.
When data cache read the address storage space when enough big, for easy to operate, also can with all data conversion storages of having stored among the control cache to data cache read the address storage space, to this, the present invention does not do concrete qualification.
In the embodiment of the invention, will control cache and data cache and carry out separate management, wherein, CPU only directly connects control cache.When the externally fed that detects described motherboard circuit when mainboard detecting unit 201 is interruption status, trigger described power module start unit 202, utilize described power module to keep power supply; First power module is enabled unit 202 and is kept under the situation of power supply at described power module, and the system file data unloading relevant with the data message index that makes CPU to control to have stored among the cache read the address storage space to data cache's.Like this, even CPU outage, leave the system file data relevant that data cache reads in the storage space of address in and can not lose yet, thereby the assurance system can not cause controlling the defective that the cache store data inside is lost when abnormal power-down takes place with the data message index.
For the ease of the present invention is further understood, describe the present invention below in conjunction with the specific embodiment of the present invention.
Usually, according to OS according to the division of the data type of being stored to the data space in the data cache, data space in the data cache specifically can be divided into and read address storage space and write address storage space, read the address storage space and be used for depositing specially read-only data, but the write address storage space is used for depositing specially write data.
When the externally fed that detects this storage system is interruption status, enable the power module of described motherboard circuit inside, continue to keep the power supply of CPU by this power module, control CPU will control the system file data unloading relevant with search tree of having stored among the cache and read the address storage space to data cache, read the address storage space when enough big as data cache, for easy to operate, also all data conversion storages that control can have been stored among the cache are read the address storage space to data cache.
Like this, even CPU outage leaves the system file data relevant with search tree that data cache reads in the storage space of address in and can not lose yet, thereby the assurance system can not cause controlling the defective that the cache store data inside is lost when the generation abnormal power-down.And, since with the system file data unloading to Data Buffer Memory read interrupted power supply behind the storage space of address to CPU, only need to utilize the electric power source pair of module ASIC that is arranged on motherboard circuit inside to power, therefore reached cost-effective purpose.
