AI Technical Summary

Benefits of technology

The patent describes a system and method for allowing multiple servers to access data stored on a USB device simultaneously. This is achieved by assigning each server with a separate memory area in the system's memory device, which is connected to the plurality of servers through a switch controller. This system can be used in a blade center to allow quicker access to data from a USB key and can save time in configuring blade servers.

Problems solved by technology

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.
Finally, another drawback of such conventional arrangements is that the access to the USB key is time consuming.

Embodiment Construction

[0026]Embodiments of the invention are described herein after by way of examples with reference to the accompanying figures and drawings.

[0027]With reference to FIG. 2, there is depicted a schematic block diagram of a management module 202 used in one embodiment. Also shown is a blade 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 the management module 202. Note that while management 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.

[0028]Management module 202 is coupled to each blade server 204 via USB bus lines 206-0 to 206-n.

[0029]Management module 202 includes a USB port 208 to allow connection of a USB device 210, in compliance with the Universal Seri...

Abstract

A system for sharing data contained on a peripheral device amongst a plurality of blade servers is disclosed. The system includes a memory device for storing the data contained on 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 coupled to the memory device for assigning one of the memory areas to each blade server. The system also includes a switch controller coupled to the processor and to the plurality of blade servers for establishing communication between the plurality of blade servers and the plurality of assigned memory areas.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]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.TECHNICAL FIELD[0002]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.BACKGROUND[0003]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.[0004]Blade servers are thin servers that insert into a single rack-mounted chassis which supplies shared power, cooling, and networking infrastructure.[0005]Each server is an independent server having its own processors, memory, storage, network controllers, operating system, and applications.[0006]Blade se...
