Abstract
Description
- This application claims the benefit of priority of European Patent Application No. EP09305606 (Docket No. FR920090004) entitled “Virtual USB Key for Blade Server,” which was filed on Jun. 26, 2009, and is hereby incorporated by reference.
- The present invention relates generally to blade centers and more particularly to a system and method for providing to blade servers a virtual access to universal serial bus (USB) key.
- Bladecenter is a widely used architecture in datacenters. Bladecenter allows housing multiple blade servers in a single chassis. It is used to save space and improve system management.
- Blade servers are thin servers that insert into a single rack-mounted chassis which supplies shared power, cooling, and networking infrastructure.
- Each server is an independent server having its own processors, memory, storage, network controllers, operating system, and applications.
- Blade servers allow more processing power in less rack space, simplifying cabling and reducing power consumption.
- The advantage of blade servers comes not only from the consolidation benefits of housing several servers in a single chassis, but also from the consolidation of associated resources (like storage and networking equipment) into a smaller architecture that can be managed through a single interface.
- Each blade server typically comes with several local drives. For additional storage, blade servers can connect to a storage pool facilitated by a network-attached storage, Fiber Channel, or iSCSI storage-area network.
- A blade center has generally at least one USB port which is assigned to a specific blade server when the data of the USB device is to be accessed. The USB assignment is generally done by an administrator from an external computing console, which is connected to the blade servers via a management module which contains logic to allow USB data to be accessed by the assigned blade server.
- A typical blade center is illustrated in
FIG. 1 . Ablade server chassis 102 coupled to amanagement module 104 includes a plurality of blade servers 102-0 to 102-n. Themanagement module 104 offers at least oneUSB port 106 to allow connection of aUSB device 108, and aserial port 110 to connect anadministration computing console 112. The serial port may be a common COM port compliant with the well-known RS-232 standard. TheUSB devices 108 may be any type of USB compliant device that uses flash memory storage. The logic to allow the operation of blade servers, specifically the allocation of data from the USB device, is made of a micro-controller 114 which transmits the selection from theadministrative console 112 to amultiplexer 116 that receives the USB data and transmits it to the assigned blade server. - This conventional USB assignment operation is heavy, tedious and may involve errors as any new settings need to run an initial program load (IPL) of the overall system.
- Moreover, the existing system allows only one blade server to use data stored on the USB key at a time, which is a great limitation in contemporary systems because information delivered on USB keys is only shared sequentially between several blade servers. Without any limitation, an example is the famous license terms and conditions that must be approved before using software applications and which is a typical use of sharing the same data amongst a plurality of blade servers.
- Finally, another drawback of such conventional arrangements is that the access to the USB key is time consuming.
- Embodiments described herein address some or all of the aforementioned problems. Accordingly, some embodiments provide a system and a method for allowing a plurality of servers to access simultaneously data stored on a USB device.
- Some embodiments provide a system and method that improves performance of a blade center by greatly reducing the time to access data stored on a USB device.
- Some embodiments allow time saving for blade servers configuration by affording use of an external administration console.
- Further embodiments of a system and method are described in the appended independent claims.
- In one embodiment, a system for sharing data contained on a peripheral device amongst a plurality of servers is described. The system includes a memory device or other memory means for storing the data of the peripheral device. The memory device is partitioned into memory areas. Each memory area stores one copy of the data. The system also includes a processor or other configuration means coupled to the memory device for assigning one of the memory areas to each server. The system also includes a switch controller or other switching means coupled to the processor and to the plurality of servers for establishing communication between the plurality of servers and the plurality of assigned memory areas.
- In one embodiment, the system is implemented as part of a management module of a blade center to allow simultaneous access of a plurality of blade servers to data copied from a peripheral USB key.
- Further embodiments are described in the appended dependent claims.
- Further aspects of embodiments of the invention will now be described, by way of examples, with reference to the accompanying figures.
- The above and other items, features, and advantages of embodiments of the invention will be better understood by reading the following more particular description of the embodiment of the invention in conjunction with the accompanying drawings.

FIG. 2 depicts a block diagram of a server blade management module in one embodiment of the present invention. -
FIG. 3 shows a flow chart of the process to create a virtual USB key in one embodiment of the present invention. - Embodiments of the invention are described herein after by way of examples with reference to the accompanying figures and drawings.
- With reference to
FIG. 2 , there is depicted a schematic block diagram of amanagement module 202 used in one embodiment. Also shown is ablade server chassis 204 made of a plurality of blade servers 204-0 to 204-n. Blade server chassis is capable of connecting one or several blade servers to themanagement module 202. Note that whilemanagement module 202 is depicted as a single management module, in another embodiment, server blade chassis may have two management modules (not shown), the first functioning as a primary management module and the second acting as a backup management module to the first management module. -
Management module 202 is coupled to eachblade server 204 via USB bus lines 206-0 to 206-n. -
Management module 202 includes aUSB port 208 to allow connection of aUSB device 210, in compliance with the Universal Serial Bus Specification, as standardized by the USB-IF organization. - A
USB switch controller 212 is coupled to theUSB port 208, to the USB bus lines 206-0 to 206-n, and to a central processing unit module (CPU) 214. The switch controller contains logic to manage the switching operation and to allow a blade server to access its assigned memory area when in operation. In one embodiment, theUSB bus 206 is compliant to the USB 2.0 standard. - The
CPU module 214 is coupled to amemory device 216 that is partitioned into ‘n’ memory areas 216-0 to 216-n. Each memory area allows storing a copy of data copied from theUSB device 210. The memory device may be any kind of random access memory (RAM). - In operation, each blade server 204-0 to 204-0 is allowed to access only one memory area 216-0 to 216-n that has been assigned during the configuration phase.
-
FIG. 3 shows a flow chart showing the operations of the virtual USB key in one embodiment. - After the power on reset (POR)
operation 302, the memory is formatted 304 and partitioned to allocate n separate memory areas 216-0 to 216-n to the respective n blade servers 204-0 to 204-n inserted into the blade center. - The CPU initializes 306 the USB switch controller to allow each blade server to be able to access its assigned memory area via its respective USB bus 206-0 to 206-n.
- The CPU waits 308 for the detection of a plug-in of a USB device.
- When a detection occurs (branch yes), the content of the USB device is copied 310 into each memory area of the cache memory. Thereafter, the USB device may be removed from the USB port.
- When one or several blade servers access the USB device, the access may be performed simultaneously in real time with no latency, directly on the one or several respective memory areas.
- Embodiments described herein afford several improvements and novel functionality to system administrators. In some embodiments, the system administrator is no longer constrained by the use of an external console to configure the USB assignment. Moreover, embodiments of the system are rendered safer because there is no longer a need to run any IPL to save a configuration. Finally, in some embodiments the operating is fully transparent for the blade center users.
- While an embodiment of the invention is particularly shown and described, various changes in form and detail may be made therein without departing from the spirit, and scope of the invention.
