Description
Technical field
The invention belongs to the Network storage technology field, be specifically related to a kind of can with the network storage device active computer compatible mainframe, built-in, relate in particular to a kind of mainly by be built in PCI (Peripheral Component Interconnect, the Peripheral Component Interconnect standard) card on the computer motherboard and can form with the hard disk of computer motherboard, pci card data communication simultaneously, make computing machine under " standby ", " dormancy " or " shutdown " state, all can realize the network storage device of network download.
Background technology
In recent years, stochastic calculation machine technology and development of internet technology, the network application of computing machine is ubiquitous.Wherein, data download (network download is wherein a kind of task form of the network storage) becomes a kind of basic function of computing machine from the network, and usually, the computer installation of existing common hardware framework all can be realized this basic function.The main frame of realizing the computing machine of network download generally comprises: the chipset on the CPU (central processing unit) on mainboard, the mainboard (CPU), the mainboard (for example north and south bridge chip group), hard disk, internal memory, network interface card, power module, CD-ROM drive etc.Usually, the network download of computing machine is a multi job mode, for example, the user when carrying out network browsing, carry out simultaneously software upgrading download, simultaneously by software network data download such as BT.And this network download data can delay the speed of network browsing usually greatly, and therefore, the network data download was carried out in start when the user allowed Computer Processing idle usually.
Generally speaking, the duty of computing machine roughly can be divided into six kinds of states of following S0-S5:
S0 is meant the common duty of computing machine, all computer motherboards and connection device standard-sized sheet thereof, and power consumption generally can surpass 80W;
S1 is also referred to as POS (Power On Suspend, power supply is hung up), be meant that computing machine is except quitting work CPU by the cpu clock controller, other mainboard connection devices (for example hard disk, internal memory, chipset etc.) are operate as normal still, power consumption is below 30W (for example, some CPU cooling software utilizes this principle of work exactly) generally;
S2 is meant that CPU is in closed condition, and bus clock also is closed, but the equipment that all the other mainboards connect still turns round;
S3 is meant STR (Suspend to RAM, internal memory hang up), also is not to use the longest state of using of person, and STR enters operating state data before the STR to system to be stored in the internal memory and to go.Under the STR state, main circuit power still continues as the most necessary power devices such as internal memory, do not lose to guarantee data, and other equipment all is in closed condition, and the power consumption of system is extremely low.In case we press Power button (host power switch), system just is waken up, at once reading of data and return to duty before the STR from internal memory.The read or write speed of internal memory is exceedingly fast, thus we to feel to enter and leave the time that the STR state spent only be several seconds, power consumption is no more than 10W;
S4 is also referred to as STD (Suspend to Disk, hard disk hang up), and the system primary power of being meant cuts out, but hard disk is still charged and can be waken up, and information is written in the hard disk in this moment internal memory, and all parts quit work;
S5 is meant and connects power supply at interior all devices Close All, the no power consumption of computing machine itself.
In the above state, usually, S0 is a normal operating conditions; S1, S2 state are referred to as " power saving " state, rolling mouse, can wake computer up by any keyboard; The S3 state is referred to as " standby (Standby) " state; The S4 state is referred to as " dormancy (Hibernate) " or " sleep (Sleep) " state usually; The S5 state is referred to as " shutdown " state.With the network download is example, and computing machine is usually operated under the S0 state when daily execution network download, and under S3, S4 and S5 state, the computing machine of prior art is may not realize the network download task at least.Therefore, the computer user normally needs to operate in the duty of S0 when carrying out the network download of larger data.Generally speaking, the computer user is being in order to make network download not influence network speed when it uses, normally the user leave allow under the state computer run at the S0 state, allow it automatically perform network download.Like this, though active computer can better be realized network storage tasks such as network download,, have the shortcoming that operating cost height, power consumption are big, shorten the computing machine life-span.
At the above demand, proposed in the prior art a kind of network attached storage that is exclusively used in network download (Network Attached Storage, NAS).Need carrying out during network storage tasks such as this device utilization execution network download of task is simple, the less characteristics of related hardware of requirement operation, forms one with relative hardware simplicity structure (with respect to main frame) and is similar to the file server that is exclusively used in network download.NAS generally includes microprocessor, network control module, be used for the hard disk of data storage and controller thereof, load module, fixed memory module, display module etc., by with the upper module co-ordination, the user can directly be connected with network by network interface, realizes network data services.Therefore, have relative cost low (with respect to computing machine), availability height, conveniently advantage such as install and use.
Simultaneously, also propose a kind of DAS (Direct Attached Storage, direct attached storage) in the prior art, also can be described as SAS (Server-Attached Storage, server extra storage).DAS is defined as directly being connected the data storage device under various servers or the client-side extensions interface, and it depends on server, itself is piling up of hardware, does not have any storage operating system.In this mode, memory device is directly to arrive server by cable (normally scsi interface (SmallComputer System Interface, small computer system interface) cable), and I/O (input/input) request directly sends to memory device.
No matter be NAS or DAS, with respect to main frame all is a separate equipment device, along with the individual application demand of the network storage is more and more wider, the personal user better realizes network storage function, generally be not ready to spend again high price to buy NAS or DAS very much, the substitute is, normally make the main frame long-play realize the self networks storage demand in the S0 state.
Therefore, be necessary to propose low-cost network storage device a kind of built-in computer formula, that be mainly used to the function of alternative NAS or DAS.
