The present disclosure relates generally to information handling systems and, more particularly, for remote access and remote mounting of Universal Serial Bus (USB) devices to servers in an information handling system.
As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option available to users are information handling systems. An information handling system generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes, thereby allowing users to take advantage of the value of the information. Because technology and information handling needs and requirements vary between different users or applications, information handling systems may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated. The variations in information handling systems allow for information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, information handling systems may include a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems, e.g., computer, personal computer workstation, portable computer, computer server, print server, network router, network hub, network switch, storage area network disk array, multiple disk system and telecommunications switch.
In large a scale data center having many servers, remote access of each these servers is required. A server interface pod (SIP) has become widely accepted for facilitating keyboard, video monitor and mouse (KVM) remote access to each of the servers. Use of a KVM SIP avoids having to physically walk to each server and plug-in or otherwise locally connect a keyboard, video monitor, and mouse to a server that requires administrator access.
Since present technology KVM SIPs only allow keyboard, video monitor and mouse remote access to each server in an information handling system, an administrator and/or technician still has to locally mount (i.e., connect) to a selected server a Universal Serial Bus (USB) device, e.g., CDROM, digital versatile disc or digital video disc (DVD), removable non-volatile memory (e.g., memory stick, tape, hard disc), etc., when required. What is needed is a KVM USB Internet protocol (IP) SIP that would allow remote mounting of a USB device to a selected server in addition to remote access of the selected server with a keyboard, video monitor and mouse.
According to a specific example embodiment of this disclosure, an apparatus for coupling a remotely located keyboard, video monitor, mouse and USB device to any one of a plurality of servers in an information handling system may comprise: a keyboard, video monitor, mouse (KVM) Universal Serial Bus (USB) Internet Protocol (IP) remote device having interfaces for coupling to a keyboard, a video monitor, a mouse, a USB device, and an IP Ethernet fabric; a plurality of server interface pods (SIPs), wherein each of the plurality of SIPs have interfaces for coupling to a server keyboard interface, a server video monitor interface, a server mouse interface, a USB interface, and the IP Ethernet fabric; and a digital KVM USB switch comprising a plurality of IP Ethernet fabric interfaces, wherein the IP Ethernet fabric interface of the KVM USB IP remote device is coupled to one of the plurality of IP Ethernet fabric interfaces of the digital KVM USB switch and each of the plurality of SIPs IP Ethernet fabric interfaces is coupled to a respective one of the plurality of IP Ethernet fabric interfaces of the digital KVM USB switch; wherein the digital KVM USB switch selects which one of the plurality of SIPs is coupled to the KVM USB IP remote device such that the server coupled to the selected one of the plurality of SIPs is remotely controlled by the keyboard, the video monitor and the mouse, and a USB device that is coupled to the USB interface of the KVM USB IP remote device is mounted to the server coupled to the selected one of the plurality of SIPs.
According to another specific example embodiment of this disclosure, an information handling system having a plurality of servers and remote control of those plurality of servers may comprise: a keyboard, video monitor, mouse (KVM) Universal Serial Bus (USB) Internet Protocol (IP) remote device having interfaces for coupling to a keyboard, a video monitor, a mouse, a USB device, and an IP Ethernet fabric; a plurality of server interface pods (SIPs), wherein each of the plurality of SIPs have interfaces for coupling to a server keyboard interface, a server video monitor interface, a server mouse interface, a USB interface, and the IP Ethernet fabric; and a digital KVM USB switch comprising a plurality of IP Ethernet fabric interfaces, wherein the IP Ethernet fabric interface of the KVM USB IP remote device is coupled to one of the plurality of IP Ethernet fabric interfaces of the digital KVM USB switch and each of the plurality of SIPs IP Ethernet fabric interfaces is coupled to a respective one of the plurality of IP Ethernet fabric interfaces of the digital KVM USB switch; wherein the digital KVM USB switch selects which one of the plurality of SIPs is coupled to the KVM USB IP remote device such that a respective one of the plurality of servers coupled to the selected one of the plurality of SIPs is remotely controlled by a keyboard, a video monitor and a mouse, and a USB device that is coupled to the USB interface of the KVM USB IP remote device is mounted to the respective one of the plurality of servers coupled to the selected one of the plurality of SIPs.
According to yet another specific example embodiment of this disclosure, a method for coupling a remotely located keyboard, video monitor, mouse and USB device to any one of a plurality of servers in an information handling system may comprise the steps of: coupling a keyboard, video monitor, mouse (KVM) Universal Serial Bus (USB) Internet Protocol (IP) remote device to a keyboard, a video monitor, a mouse, a USB device, and an IP Ethernet fabric; coupling a plurality of server interface pods (SIPs) to respective ones of a plurality of servers in an information handling system; and coupling a digital KVM USB switch to each of the plurality of SIPs and the KVM USB IP remote device through the IP Ethernet fabric; wherein the digital KVM USB switch comprises the step of selecting which one of the plurality of SIPs is coupled to the KVM USB IP remote device such that the server coupled to the selected one of the plurality of SIPs is remotely controlled by the keyboard, the video monitor and the mouse, and a remote USB device coupled to the KVM USB IP remote device is mounted to the server coupled to the selected one of the plurality of SIPs.

The KVM USB IP interface 316 may add USB packets to the existing packets used for operation of the video monitor 218, keyboard 212 and mouse 214. These combination of KVM and USB packets may be routed through the network switch 210 to the digital KVM USB switch 308 and then to the respective ones of the plurality of USB-SIPs 304. The digital KVM USB switch 308 may direct which one of the plurality of USB-SIPs 304 is coupled to the remotely located video monitor 218, keyboard 212, mouse 214 and USB device 206. By doing so the server 202 coupled to that one of the plurality of USB-SIPs 304 is thereby controlled remotely and a remotely located USB device 206 may be mounted thereto.
This provides a completely transparent connection to any selected server in a data center information handling system by allowing the remotely located user to operate the keyboard 212, video monitor 218, mouse 214 and USB device 206, for example, across the digital KVM USB switch fabric, a local area network (LAN), a wide area network (WAN) or even over the Internet. Whenever the user may switch to a different server 202 via the digital KVM USB switch 308, the user located USB device 206 may also be redirected (e.g., mounted) to that server 202. This provides benefits to information handling system data centers with high server density as follows: 1) A single console box with KVM control and a virtual USB device for all servers. 2) Full server access and control capabilities from any convenient location and at any time. 3) Reliability, low cost, low maintenance and easy installation. And 4) reduced administrator/technician travel time so as to further reduce total cost of ownership (TCO).
