Abstract

The invention provides a multi-path server architecture design with redundant and symmetrical hot-plugging IO boxes, and belongs to the field of multi-path server systems. According to the multi-path server architecture design, the redundant and symmetrical hot-plugging IO boxes are provided, data in the redundant IO boxes can be transmitted synchronously, the redundant IO boxes still receive and send the data when one of the redundant IO boxes has a problem, and the data transmittability of a system can not be affected. In addition, the IO boxes are hot plugging; when the system needs to expand an IO device, or change the configuration of the IO device, no shutdown maintenance is needed, and it is guaranteed that no risk exists in the on-line and thermal maintenance process of the system through the redundant and hot-plugging design.

Description

A kind of multipath server architecture design that adopts the hot-swappable IO case of redundancy symmetry

technical field

the present invention relates to multipath server system, specifically a kind of multipath server architecture design that adopts the hot-swappable IO case of redundancy symmetry.

Background technology

4 tunnels that multipath server comprises current main-stream, 8 tunnels and above server product.Because processor is numerous, system-computed performance is powerful.For computational data is transmitted timely and effectively, multipath server requires there is reliable and stable IO equipment, for high performance calculating provides support.

The IO case of tradition multipath server framework one general configuration unsymmetric structure, and IO case redundancy feature can be provided, once IO case goes wrong, whole system will lose data transmission capabilities, higher calculated performance is also just futile.

Summary of the invention

The present invention be directed to the core application that requires high reliability, a kind of multipath server system of highly reliable IO equipment can be provided.

Feature of the present invention is:

1. in multipath server system, adopt the IO case of symmetrical structure, have the IO casing that even number is identical, symmetrical up and down, or symmetrical structure;

2. the IO casing of symmetrical structure redundancy each other, be that its inner IO daughter card configuration is identical, and function and application is identical, once certain IO casing breaks down, another symmetrical redundancy IO case can be born identical operation, safeguards system failure-free operation;

3. IO casing can be supported overall thermal plug, in the time of need to changing IO configuration, and can online hot maintenance.

A kind of multipath server architecture design that adopts the hot-swappable IO case of redundancy symmetry that the present invention proposes, its architecture is as follows: calculate module, backboard, IO module

Wherein calculate and in module, comprise the parts such as processor, internal memory;

Backboard is responsible for the connection between each module;

IO module comprises the IO equipment such as PCIE, requires symmetrical IO structure, and IO case is symmetrical up and down, or symmetrical structure, and it is hot standby that two IO modules require to do in application, and support casing hot plug.

The hot standby application of IO case:

Symmetrical IO case adopts the identical IO equipment such as PCIE, adopts the mode of double-network redundant, inputs each standby IO device address in management software, once main IO case equipment cannot be communicated with, will automatically switch to corresponding standby IO device address in standby IO case.Client can be by main IO case device address, from IO case device address and system communication.

The hot plug of IO case:

First, IO case configures signal in place and special-purpose casing heat removes button.

When IO case heat is added into system, system detects IO case signal in place, is powered on, and trigger BIOS interruption by monitoring management system to IO case; Operating system is processed hot interpolation event immediately, adds successively the IO equipment in IO case in bus.

When IO case needs heat to remove, to press heat and remove button, triggering system is interrupted; Operating system is processed immediately heat and is removed event, removes successively IO equipment in IO case in bus, then, by the KCS interface notice monitoring management system of BIOS, finally gives the power-off of IO case, can carry out physical thermal and remove.

This multipath server framework of introducing herein, can provide the IO case of redundancy symmetry, and data are synchronous transmission in redundancy IO case, and when one of them IO case goes wrong, the IO case of redundancy is still receiving and sending data, and the data transmission capabilities of system is unaffected.And this IO case can also carry out hot plug.System need to be expanded IO equipment, or during the configuration of change IO equipment, safeguards that the design of redundancy+hot plug guarantees that system online hot maintenance is without any risk without shutting down.Compared with traditional IO subcard hot plug, the hot plug of IO case can be supported the hot plug of more IO subcard, more succinctly easy-to-use, then in conjunction with the architecture design of redundancy IO, more reliable and more stable than single deck tape-recorder hot plug.

Accompanying drawing explanation

Accompanying drawing 1 is the hot-swappable IO case schematic diagram of redundancy symmetry;

Accompanying drawing 2 is the hot standby schematic diagram of IO case;

Accompanying drawing 3 is IO case hot plug design diagrams.

Embodiment

1. the configuration of the IO case of system configuration symmetry, and the IO subcard equipment in IO case is identical.

2. in management software, input each standby IO device address.

Example:

No. 1 IB card IP:10.114.72.1 of main IO case

From No. 1 IB card IP:10.114.72.10 of IO case

No. 2 network interface card IP:10.114.72.2 of main IO case

From No. 2 network interface card IP:10.114.72.20 of IO case

Once main IO case equipment cannot be communicated with, will automatically switch to corresponding standby IO device address in standby IO case.

3. in the time need to safeguarding IO case or equipment wherein, the heat of pressing corresponding IO case removes button, and triggering system is interrupted; Operating system is processed immediately heat and is removed event, removes successively IO equipment in IO case in bus, and then, by the KCS interface notice monitoring management system of BIOS, monitoring management system is to the power-off of IO case, and user can extract maintenance by casing.

4. again the IO case after safeguarding is turned back to system, system detects IO case signal in place, is powered on, and trigger BIOS interruption by monitoring management system to IO case; Operating system is processed hot interpolation event immediately, adds successively the IO equipment in IO case in bus.

To sum up, the multipath server architecture design of the hot-swappable IO case of this employing redundancy symmetry of introducing herein has very strong novelty, can improve reliability and the ease for use of IO system; There is splendid practicality simultaneously.
