Description

The The invention relates to a server with at least one external interface for connection to a local data network and a method for controlling a data flow of a server in a local data network.

In a local data network, also called Local Area Network (LAN), there is usually one Variety of network control units, switching computers and Servers. The connection of a server to such a data network via a or more cables.

One Server has external interfaces through which the server to the local Data network is connected. Such an interface will also called LAN port. The LAN ports is assigned a special purpose. For example is one of the LAN ports exclusively for the transmission of administrative data provided by the server or from the local data network. Another LAN port is then exclusive for the transmission of Application data of the server or provided from the local data network. The respective LAN ports are over Cable connections connected to the local data network. In huge Data centers with a variety of servers performs such a connection between LAN ports and network control units or switching computers of the local data network about cabling problems.

task The invention is therefore to specify a server so that its LAN ports are better usable.

These Task is solved by a server of the type mentioned, wherein the server at least one computing component, an administrative component and a switch and the switch is set to Connection between one of the at least one external interface and the at least one computing component or the management component manufacture.

These Task is also solved by a method for controlling a data flow of a server in a local data network, wherein the server has at least one Computing component, an administrative component, at least two external interfaces, including a management data interface, to connect to the local data network, with the steps: Setting a configuration of a switch of the server for setting, which interfaces are connected to which components of the server connect the administrative data interface to the administrative component the server to submit of administrative data and connecting the at least one other external interface with the at least one data processing component of the Servers to submit of application data.

These Task is also solved by a method for controlling a data flow of a server in a local data network, wherein the server has at least one Computing component, an administrative component and at least one external interface for connection to the local data network, solved with the steps: Setting a switch configuration the server determining which requests to which components the server should be forwarded, and therefore the following Steps to be performed: Connect the at least one external interface to the management component and connecting the same or, if present, another external interface with the at least one data processing component.

Of the Switch the server is preferably a small LAN switch. The integration of the switch in the server allows a flexible configuration of the external interfaces of the server, for example, LAN ports to connect the server to the local data network. Of the Server-integrated switch provides a connection between at least one of the external interfaces and the at least one data processing component or the administrative component. For this purpose, the switch itself also Interfaces on (switch ports). About these interfaces of Switches are the external interfaces of the server on the one hand and the components of the server, on the other hand, connectable. By This server-integrated switch eliminates the need for fixed cabling the external interfaces with the named components in the server.

One Another advantage of the invention is that a user decides how many or over which external interfaces of the servers with the local data network is connected. A user is thus free which external Interface to which purpose should be used: Application data will be about transmit an external interface, If this is a data interface, administrative data is about the transmitted external interface, this is a management data interface.

• – jede externe Schnittstelle kann frei als entweder Verwaltungsdatenschnittstelle oder Datenschnittstelle festgelegt werden, zum Beispiel erst nach der Verkabelung,
• – eine externe Schnittstelle kann sowohl als Datenschnittstelle als auch als Verwaltungsdatenschnittstelle verwendet werden.

The switch makes it possible to operate the server in several alternative ways on the local data network:

• Each external interface can be freely defined as either a management data interface or a data interface, for example only after cabling,
• - An external interface can be used both as a data interface and as a management data interface.

In The configuration of the switch is defined as the data or Data packets are forwarded within the switch. The administrative component or the data processing components of the server only receive those data or data packets that have their own media access control (MAC) address or a broadcast MAC address included. All other data or data packets are from the management component or the respective data processing component discarded.

Between the administrative component of the server, such as a server Management processor and one of the external interfaces of the server There is a logical data connection via a LAN protocol, for example a Transmission Control Protocol (TCP) or Internet Protocol (IP). At this logical connection level, the required information for a connection between the administrative component and one of the exchanged external interfaces of the server. A connection between one of the data processing components and one of the external ones Interfaces of the server are also made in this way.

In According to an advantageous development, the switch is set up to a connection between a management data interface of the To create servers and the management component of the server, to over to submit this connection administrative data, and another Connection between one of the at least one external interface, except the management data interface, and the at least one computing component of the server to over to transmit this connection application data. This has the advantage that the administrative data and application data are separated transferred to the local data network or can be received from this. Such a configuration the switch offers the greatest possible protection for the traffic on a local data network.

In According to an advantageous development, the switch is set up to based on predetermined configuration data for the switch a connection between the management component or the at least one computing component and a particular one of the at least one external interface to make over this external interface management data or application data to convey. The advantage of this is that the switch traffic to only derives an external interface of the server, which thus for different Types of data is usable. For example, in the configuration data determines which and how many external interfaces are used should be whether an external interface exclusively for one certain use, for example, as a management data interface is to be used, or what data rate is provided, etc. Advantageously The switch is located on a motherboard of the server.

In In another advantageous development, the switch is on one separate board in a housing of the server. This has the advantage that the switch in a so-called I / O Bay of the server installed and easily replaceable is.

advantageously, is the association between the at least one external interface or the provided as a management data interface external interface and components of the server configurable. The controllable switch is used to make the connections. A user who wants to change the data path between the server and the data network reached this over a change the said assignment, ie a change of the configuration data. This also includes the advantage that the switch is reconfigurable is without changing the external cabling of the server.

Further advantageous embodiments of the invention are specified in the subclaims.

The The invention will be explained in more detail with reference to embodiments.

1 schematically shows a server as the first embodiment 1 with external interfaces 8th , a switch 2 , two data processing components 3 , an administrative component 4 and two sensors 5 ,

The server 1 is via the external interfaces 8th to a local data network 7 connected. The external interfaces 8th are in the server 1 with the switch 2 connected.

In this embodiment, the switch 2 configured to only have two of the existing external interfaces 8th and one of them is a management data interface VDSS. Of course, when setting a configuration of the switch 2 also the other external interfaces 8th As administrative data interface VDSS be provided or it can also all existing external interfaces 8th of the server to be used.

The switch 2 is located on a motherboard of the server 1 in the 1 is not shown. With the switch 2 are the two computational components 3 and the administrative component 4 of the server 1 connected.

The administrative component 4 is for example a so-called "server management processor", which is the server 1 supervised. The administrative component 4 determines management data VD, such as data of the sensors 5 which include a temperature of the hard disk or power supply, fan speed, etc., and an I ² C bus from the sensors 5 to the administrative component 4 to get redirected.

The data processing component 3 is, for example, a LAN chip and transmits application data AD. Application data AD is, for example, data from a database, e-mails, text files, images etc.

The switch 2 makes a connection 6 between the administrative component 4 and the management data interface VDSS. The from the administrative component 4 determined administrative data VD are via this connection 6 into the local data network 7 forwarded, for example, if the temperature in the server 1 exceeds a maximum value. The determined management data VD can, for example, be sent to another device in the local data network 7 where they are processed by a processor.

The switch 2 represents in an optional development of this embodiment, a connection 6 between the same management data interface VDSS and one of the two computing components 3 ago. The data processing component of this 3 transmitted application data AD, for example, modified entries in a database are using this connection 6 into the local data network 7 forwarded, for example for comparison with entries from other databases. The administration data interface VDSS is thus used flexibly in this embodiment, namely, if necessary, for forwarding application data AD or administration data into the local data network 7 , The connection 6 the administrative data interface VDSS with the data processing component 3 or the administrative component 4 is therefore changed dynamically during the operation of the server.

In a simple design becomes a configured setting of the switch during operation not changed anymore.

The switch 2 also provides another connection 6 between another external interface 8th and the other of the two computational components 3 come to know about this connection 6 Application data AD derived from this computational component 3 be determined in the local data network 7 forward. So the load can be on several external interfaces when forwarding application data AD 8th of the server 1 be distributed.

The from the administrative component 4 determined management data VD or that of one of the two data processing components 3 transmitted application data AD can also over the local data network 7 at the administrative data interface VDSS or the external interface 8th Can be requested. These requests are made by other devices from the local data network 7 to the server 1 cleverly.

The switch 2 stops after receiving a request for one of the computational components 3 a connection 6 between the external interface 8th which the request received and the data processing component 3 of the server for which the request is intended.

Upon receipt of a request or data for the administrative component 4 represents the switch 2 a connection between the management data interface VDSS at which the request was received and the management component 4 of the server 1 ago.

When receiving for the data processing component 3 certain application data AD at the management data interface VDSS or the external interface 8th puts the switch 2 a connection 6 for transmitting the received application data AD between the management data interface VDSS or the external interface 8th and the computational component 3 which is to process the application data AD, for example an entry in a database, etc.

Making such connections between the external interfaces 8th of the server 1 is a dynamic configuration of the switch 2 ,

In this embodiment too a single external interface 8th are sufficient to forward administrative data VD and application data AD. In order to achieve a better load distribution, in particular the application data AD, these are provided via several external interfaces 8th forwarded.

2 shows a server as a second embodiment 1 , wherein for security reasons, the management data interface VDSS is provided exclusively for forwarding management data VD. Administrative data VD and application data AD are thus via two different external interfaces 8th forwarded.

The switch 2 makes a connection 6 between the administrative data interface VDSS and the management component 4 of the server 1 ago. About this connection 6 administrative data VD are from the administrative component 4 For example, another device in the local area network 7 forwarded. Requests to the administrative component 4 or receiving for the administrative component 4 certain management data VD at this management data interface VDSS are exclusively over this connection 6 forwarded.

The switch 2 represents another connection 6 between the other external interface 8th and the data processing components 3 of the server. Application data AD from the data processing components 3 or requests for the computational components 3 from the local data network 7 , are exclusively via this external interface 8th or if available via another external interface 8th , except the administrative data interface VDSS, forwarded.

Establishing such connections between the management data interface VDSS and the management component 4 of the server 1 on the one hand, and between the external interface 8th and the data processing components 3 of the server 1 on the other hand, is a static configuration of the switch.

3 shows a flowchart of a method for controlling a data flow of a server 1 , where the server 1 in this embodiment, a data processing component 3 , an administrative component 4 , at least two external interfaces 8th including a management data interface VDSS, for connection to the local data network 7 having.

In a step S1, a configuration of a switch becomes 2 of the server 1 which determines what components of the server are set 1 which of the external interfaces 8th including the administrative data interface VDSS. The components of the server 1 are the administrative component 4 and the data processing components 3 ,

In a step S2, the switch creates 2 a connection 6 between the administrative data interface VDSS and the management component 4 of the server 1 , Are in another embodiment, multiple management components 4 in the server 1 provided, the switch created 2 also connections 6 between them and the management data interface VDSS. In a step S3, management data VD about the connection established in step S2 6 forwarded. This includes forwarding administrative data VD of the management component 4 into the local data network 7 , or requests for the administrative component 4 from the local data network 7 ,

In a step S4, the switch 2 also a connection 6 between the other external interface 8th and the computational component 3 ago. Are in another embodiment, multiple data processing components 3 in the server 1 present, the switch creates 2 also connections 6 between these and the other external interface mentioned 8th , In a step S5, application data AD is acquired via the connection established in step S4 6 forwarded. This includes forwarding application data AD to the local data network 7 , wherein the application data from the data processing component 3 or forwarding requests for the computational component 3 from the local data network 7 ,

See the configuration of the switch set in step S1 2 the use of several external interfaces 8th to forward AD application data before, the switch provides 2 in step S4 connections 6 between these external interfaces 8th and the multiple data processing components if present 3 of the server 1 ago. In step S5 then these connections 6 Application data AD transmitted and so distributes the load.

4 shows a development of the embodiment 3 in which a dynamic configuration of the switch is provided. After setting the configuration of the switch 2 in step S1, which provides the transmission of management data VD via the management data interface VDSS, it is checked in a step S6 whether administration data VD is to be transmitted via the management data interface VDSS. On a positive statement, the switch 2 in step S2, the connection 6 between the administrative data interface VDSS and the administrative component 4 ago. In step S3, the management data VD is acquired via the connection established in step S2 6 forwarded.

In the case of a negative determination in step S6, it is checked in a step S7 whether application data AD is being transmitted via the other external interface 8th to be transmitted. If it is positive, the switch connects in step S4 6 between the other external interface 8th and the computational component 3 ago. In step S5, the application data AD is set via the connection made in step S4 6 forwarded. In the case of a negative determination in step S7, the method is continued with step S6.

5 shows a flowchart of a second method for controlling a data flow of the server 1 , where the server 1 unlike the first method, only a single external interface 8th for connection to the local data network 7 used and the server 1 several data processing components 3 having.

In a step S8, the configuration of the switch 2 is set, which determines which requests to which components of the server 1 to get redirected. After setting the configuration of the switch 2 In a step S9, it is checked whether a request, designated AVD in the figure, comes from the local data network 7 to the administrative component 4 is present. If found positive, the switch 2 in step S11 the connection 6 between the external interface 8th and the administrative component 4 of the server 1 forth to submit the request.

If the determination is negative in step S9, it is checked in step S10 whether a reception, denoted by EVD in the figure, of the management component 4 certain administrative data VD is present. If affirmative, said step S11 follows. In a negative determination in step S10, it is checked in a step S12 whether a request, denoted in the figure with AAD, from the local data network 7 to the data processing component 3 is present. If found positive, the switch 2 in a step S13, a connection 6 between the external interface 8th and the computational component 3 of the server 1 ago.

If the determination is negative in step S12, it is checked in step S14 whether a reception, denoted EAD in the figure, of the data processing component 3 certain application data AD is present. If affirmative, the said step S13 follows. If negative, the process proceeds to step S9.
