Description

A kind of method of one key switching PCIE Switch operating modes
Technical field
The present invention relates to server-bus board design fields, and in particular to a kind of one key switching PCIE Switch work The method of pattern.
Background technology
PCIE is by the strong characteristic of its efficient general, as a kind of common interfaces in computer, server, storage industry It is used widely.As the demand to performance and function is continuously increased, HBA cards, HCA cards, GPU card based on PCIE interfaces, Network interface card, OCP cards and a variety of accelerator cards occur in succession.The limitation of CPU PCIE port numbers is limited to, is supported in same system PCIE device limited.To solve the limited PCIE ports of CPU, with increasingly increased function, the contradiction of performance requirement, it is used for The PCIE Switch of extension PCIE ports are born therewith.
The common schema that PCIE Switch are supported at present is Base Mode, VS Mode, NT Mode and Fabric patterns. Wherein, Base Mode are common pattern.Base Mode are that a uplink port is expanded to multiple downlink ports, are to realize most The more application of a common extension.As shown in Figure 1.Attached drawing 2 show VS Mode, and (Virtual Switch Mode are virtual Switch) pattern, i.e., virtual Switch patterns.One Switch can be invented two or more by VS Mode Switch, each Switch works independently, and can realize Failover between two Switch.Attached drawing 3 show NT Mode patterns.NT Mode are Non-transparent Mode, i.e. non-transparent transmission pattern.NT Mode patterns can be realized together Host coexists under one Switch, can access the Device under Switch, and can realize the information exchange between Host.Often at present See most two NT mouthfuls of Swicth, three Host can be accommodated and coexisted.Attached drawing 4 show Fabric Mode patterns.Fabric Mode can support multiple Host to coexist, and can set up Fabric networks by Fabric ports, realize more Switch interconnections, And to the equipment of Share I O functions is supported to realize the function that Share IO (shared equipment) are accessed.
Machine performance can be increased using different patterns under different application scenarios, improve treatment effeciency.Some The switching of various modes is needed to meet application demand under particular surroundings.For pattern switching, it is necessary to by configuring Strap Pin It is realized with adjustment firmware, Neither of the two can be dispensed in most cases.
It is described by taking the switching that PLX companies PCIE Switch carry out common Base Mode and VS Mode as an example, at present Frequently with method it is relative complex, basic process approximately as：
1. shutdown power-off manually, if needing to split out board outside cabinet during operation in inconvenient cabinet in some cases；
2. it needs through toggle switch or replaces resistance adjustment Strap Pin input states on Strap Pin；
3. the firmware of couple PCIE Switch refreshes, the refreshing mode generally taken at present include it is offline refresh and Line refreshes mode：
A) FLASH chip that offline refreshing will store firmware is removed from PCB, passes through weight after replication tool again burning Newly it is welded on PCB or is put on corresponding chip carrier.
B) online burning needs the debugging specified by PCIE Switch gauge to connect its debugging port to refresh firmware
4. board reinstalls machine, start is powered on.
From the point of view of whole process, PCIE Switch mode switching operations are very cumbersome, and the consuming time is longer, is unfavorable for imitating Rate is promoted.Under some site environments, it is also necessary to cabinet adjustment Strap Pin states are opened, meanwhile, it is also very to refresh firmware Difficult, this brings great inconvenience to using.
In view of the above-mentioned problems, a kind of method of one key switching PCIE Switch operating modes of the present application, can pass through Relevant options realize operating mode one key switching under UI buttons or BMC Telnets interface on the outside of cabinet, are related in handoff procedure And the refreshing FW arrived, restart system, configuration Strap Pin etc. and all carried out automatically by BMC, without artificially interfering, easy to operate letter It is single, substantially increase testing efficiency.

As shown in Figure 5 there are two switching control mouths：
One is accessed BMC for button by CPLD, can be disappeared by CPLD progress buttons and be trembled work.BMC detects switching Meeting execution pattern switch operating after push button signalling, and light corresponding indicator light.Such mode needs BMC to prestore new version Configuration firmware is opened from the external USB port reading associated firmwares of BMC in write-in FLASH.
Another is the management port of BMC, logs in BMC by terminal computer, Switch is refreshed, and is obtained new solid The mode of part can also be uploaded in addition to two kinds that button is included by remote control port, more convenient in operation.
Specific implementation step of the present invention is as follows：
Firstly the need of at circuit design initial stage according to circuit design is carried out shown in block diagram, by corresponding switching switch and control Signal connects, and corresponding control routine is added in BMC firmware developments, and ensureing can be right under button and remote control interface Handover event is triggered, and switches over operation in accordance with the following steps：
Switch either-or switch to BMC one sides；
It brushes into new edition firmware；
Switch either-or switch to Switch one sides；
Shutdown；
Switch Strap Pin under associative mode；
Start, and light corresponding indicator light, display corresponds to interface information.
It should be evident that illustrated above is only the specific embodiment of the present invention, for the common skill in this field For art personnel, without creative efforts, other technical solutions can also be obtained according to above-described embodiment, And the equivalent variations made in the scope of protection of the invention should all be fallen within the scope of protection of the present invention, and belong to the present invention The scope of protection.
In conclusion the present invention realizes the one key switching of PCIE Switch operating modes, cut manually compared with original Mold changing formula, greatly improves work efficiency；And it realizes and is cut in some operating modes in the case of being inconvenient to start shooting case It changes.Invention increases the use scopes of pattern switching, add competitiveness of the corresponding type in identical Horizontal production.
