Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.
The steps illustrated in the flow charts of the figures may be performed in a computer system such as a set of computer-executable instructions. Also, while a logical order is shown in the flow diagrams, in some cases, the steps shown or described may be performed in an order different than here.
Fig. 1 is a schematic structural diagram of a mixed-insertion blade server according to an embodiment of the present invention, and as shown in fig. 1, the mixed-insertion blade server includes a server chassis, a backplane 100 disposed in the server chassis and having a first side 103 and a second side 104, at least one set of first connectors disposed on the first side 103 of the backplane, and at least one set of second connectors disposed on the second side 104 of the backplane; the group of first connectors comprises two first connectors 101 arranged vertically up and down, and the first connectors 101 comprise direct connection areas 1011 and non-direct connection areas 1012; the group of second connectors comprises two second connectors 102 arranged vertically up and down, and the second connectors 102 comprise direct connection areas 1021 and non-direct connection areas 1022; the direct connection area 1011 of each first connector is arranged opposite to the direct connection area 1021 of the second connector corresponding to each first connector, so that the devices on the two sides of the backboard 100 transmit signals in a signal direct connection mode; the non-direct connection region 1012 of each first connector is not aligned with the non-direct connection region 1022 of the second connector corresponding to each first connector, so that the devices on both sides of the backplane 100 transmit signals in a signal transfer connection manner.
The first connector 101 and the second connector 102 are of the same type and are used for providing an interface for signal connection of devices on both sides of the backplane.
In practical application, because the devices on the two sides of the backboard are not completely arranged right, the signal transmission modes of the devices on the two sides of the backboard include two modes, one mode is signal direct connection, and the other mode is signal relay connection. Specifically, the signal direct connection means that the direct connection area 1011 of the first connector and the direct connection area 1021 of the corresponding second connector realize the direct connection of signals on two sides of the backboard by using the projection areas of the first connector and the second connector which are superposed on the backboard, so that signal routing is reduced, and the quality of signal transmission is improved; the signal relay connection means that the projections of the non-direct connection region 1012 of the first connector and the non-direct connection region 1022 of the second connector on the backplane do not have a superposition portion, and therefore, the relay connection of the device signals that are not completely oppositely arranged on the two sides of the backplane is realized through the signal traces pre-arranged in the backplane 100.
It is to be added that two first connectors arranged up and down in the vertical direction on the first side of the backplane and two second connectors arranged up and down in the vertical direction on the second side of the backplane can implement deployment of multiple types of blade nodes in the server chassis. For example, deployment of a half-height blade node and a full-height blade node in a server chassis can be achieved by using a set of first connectors disposed on an upper side of a first side and second connectors disposed on a second side, or a set of first connectors disposed on a lower side of the first side and second connectors disposed on the second side.
It should be noted that the size of the direct connection area 1011 of the first connector 101 and the size of the direct connection area 1021 of the second connector 102 may be set according to actual needs. For example, the area 1011 of the first connector 101 may be set to be one third of the area occupied by the first connector 101, and it is understood that the area 1012 of the first connector 101 that is not directly connected is two thirds of the area occupied by the first connector 101. The embodiment of the present invention does not specifically limit the size of the direct connection region between the first connector 101 and the second connector 102.
Further, the blade server further includes a blade node and a switch, wherein the blade node is connected to the switch through the first connector 101 and the second connector 102 on the backplane 100.
It should be added that, the mixed insertion blade server may set multiple sets of first connectors and corresponding multiple sets of second connectors according to actual needs, and the backplane 100 is used to connect blade nodes and switches located at two sides of the backplane through the first connectors 101 and the second connectors 102, so that, according to actual positions of the blade nodes and switches, a suitable first connector 101 and a corresponding second connector 102 are selected from the multiple sets of first connectors and the multiple sets of second connectors to connect the blade nodes and the switches.
Further, the first connector 101 receives the interconnection signal sent by the blade node, and sends the IB signal to the corresponding second connector 102 through the direct connection region 1011.
The IB signal is an interconnection signal for the mixed insertion blade server to process inter-process communication. In practical application, the first connector 101 is directly connected to the corresponding second connector 102 through the direct connection region, and signal routing is less, so that the signal quality sent through the direct connection region is better, and therefore the IB signal with higher requirement on the signal quality can be transmitted by using the direct connection region. Of course, according to actual needs, other signals may also be transmitted by using the direct connection region, which is not specifically limited in the embodiment of the present invention.
Further, the blade node is connected to the switch through the first connector and the second connector on the backplane, specifically: the blade node is connected with the switch through a first connector arranged on the upper side of the first side face and a group of second connectors arranged on the second side face, or the blade node is connected with the switch through a first connector arranged on the lower side of the first side face and a group of second connectors arranged on the second side face.
Further, the blade nodes include half-height blade nodes, and/or full-height blade nodes.
The first embodiment is as follows:
fig. 2 is a schematic diagram of a connection relationship between a full-height blade node and a switch according to an embodiment of the present invention. As shown in fig. 2, the all-high blade node 105 is connected to one switch 106 (indicated by a straight arrow in fig. 2) through a direct connection region of a first connector 101 (see a hatched portion of the first connector 101 in fig. 2) provided on an upper side of a first side 103 of the backplane 100 and a direct connection region of a second connector 102 (see a hatched portion of the second connector 102 in fig. 2) provided on an upper side of a second side 104; full-height blade node 105 is connected to another switch 106 through a non-direct connection region of first connector 101 disposed on the upper side of first side 103 and a non-direct connection region of second connector 102 disposed on the lower side of second side 104 (see the dashed arrows in fig. 2).
Example two:
fig. 3 is a schematic diagram of a connection relationship between a half-high blade node and a switch according to an embodiment of the present invention. As shown in fig. 3, the mixed-insertion blade server is provided with 2 half-high blade nodes 107 in the vertical direction. Wherein, the half-high blade node 107 disposed on the upper side is connected to one switch 106 through the direct connection region of the first connector 101 disposed on the upper side of the first side 103 of the backplane 100 and the direct connection region of the second connector 102 disposed on the upper side of the second side 104 (see the upper straight arrow in fig. 2); half-high blade node 107 is connected to another switch 106 through the non-direct connection region of first connector 101 disposed on the upper side of first side 103 and the non-direct connection region of second connector 102 disposed on the lower side of second side 104 (see the dashed arrow in fig. 2). Similarly, a half-high blade node 107 disposed on the lower side is connected to one switch 106 via a direct connection region of the first connector 101 disposed on the lower side of the first side 103 and a direct connection region of the second connector 102 disposed on the lower side of the second side 104 (see the lower straight arrow in fig. 2); half-high blade node 107 is connected to another switch 106 via a non-direct connection region of first connector 101 provided on the lower side of first side 103 and a non-direct connection region of second connector 102 provided on the upper side of second side 104 (see dotted arrows in fig. 2)
It should be noted that, in this embodiment, the half-high blade node transmits a signal with an exchange in a manner of directly connecting the signal through the direct connection region; and transmitting the signals with another switch in a signal transfer connection mode through the non-direct connection area. That is to say, the half-high blade node in this embodiment is connected to two switches at the same time, so that when one of the switches fails, the other switch is used to ensure the normal operation of the mixed-insertion blade server.
Through the first embodiment and the second embodiment, it can be seen that the mixed insertion blade server provided by the embodiment of the invention integrates two different types of blade nodes, namely, a half-height blade node and a full-height blade node, through a backplane, realizes mixed insertion of the blade nodes and high integration density and flexible configuration of the blade server, and improves space utilization rate.
Example three:
fig. 4 is a schematic structural diagram of a backplane provided with ten sets of first connectors and ten sets of second connectors according to an embodiment of the present invention. As shown in fig. 4, ten sets of first connectors are arranged side by side on the first side 103 of the backplane, and one set of first connectors 401 includes two first connectors 101 arranged vertically up and down; ten sets of second connectors are arranged side by side on the second side 104 of the backplane, and one set of second connectors comprises two second connectors 102 arranged vertically one above the other.
By comparing and displaying the first side 103 of the back panel and the second side 104 of the back panel in the same figure, it can be seen that the projection of the direct connection area 1011 on the back panel coincides with the projection of the direct connection area 1021 on the back panel, that is, the direct connection area 1011 is arranged opposite to the corresponding direct connection area 1021; the projection of the non-direct connection region 1012 on the backplane is not overlapped with the projection of the non-direct connection region 1022 on the backplane at all, that is, the non-direct connection region 1012 is not aligned with the corresponding non-direct connection region 1022 at all.
In practical applications, limited by the space of the server chassis, with the backplane provided with ten sets of first connectors and ten sets of second connectors in the third embodiment, one mixed-insertion blade server can support mixed insertion of at most 20 half-height blade nodes, 10 full-height blade nodes, and any form of two types of blade nodes. For example, fig. 5 is a schematic diagram of a server chassis of a hybrid-add blade server according to an embodiment of the present invention, and as shown in fig. 5, the hybrid-add blade server implements hybrid-add of 10 half-high blade nodes 501 and 5 full-high blade nodes 502. In practice, two half-height blade nodes 501 in the same column are separated by a removable spacer in between, and a full-height blade node 502 can be inserted after the spacer is removed.
According to the mixed insertion blade server provided by the embodiment of the invention, the group of first connectors arranged on the first side surface of the back plate comprises two first connectors arranged up and down in the vertical direction, the group of second connectors arranged on the second side surface of the back plate comprises two second connectors arranged up and down in the vertical direction, and the first connectors and the second connectors both comprise direct connection areas and non-direct connection areas, so that mixed insertion of multiple types of blade nodes can be realized, thus, server resources can be effectively configured, the requirement of large-scale deployment can be met, and the cost and the floor area of the blade server can be reduced.
Although the embodiments of the present invention have been described above, the above description is only for the convenience of understanding the present invention, and is not intended to limit the present invention. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
