A Pre-boot Execution Environment (PXE) boot extension is loaded upon system boot and is operable to store an iSCSI boot disk identifier identifying a remote disk drive to a shared memory location. As an operating system is loaded via iSCSI over a network connection to a remote disk, an operating system iSCSI driver is loaded. The operating system iSCSI driver reads the boot disk identifier stored in the shared memory location and uses the boot disk identifier to configure the operating system.

A method restores a client device of a network on major failure of the client device. The client device is incapable of automatically booting on its own. The network includes a server computer. The method includes booting the client device over the network in the restoration operation, configuring the client device according to the boot program and saved configuration states for the client device, and copying files to the client device in accordance with the configuration. The client computer has access to a storage manager application, such as a server computer of the network operating a storage management software program. All client files, including configuration files, as well as application and data files, of the client device are saved on the network by the storage manager application. The client device is booted over the network, rather than locally to the client device by boot disk or otherwise. The boot program is loaded to the client device, and the client device retrieves configuration and file information over the network from the storage manager application. The client device configures its disk according to the configuration information, and then all other files and data of the client device at the time of failure of the client device are saved on the disk substantially in the condition and state just prior to the failure and as most recently backed up to the storage manager application. Alternatively, the client device is reset and booted via a control device either locally or otherwise connected to the client device, and substantially according to the method of the network boot.

The reliability is improved at a low cost even in a virtualized server environment. The number of spare servers is reduced for improving the reliability and for saving a licensing fee for software on the spare servers. A server system comprises a plurality of physical servers on which a plurality of virtual servers run, a single standby server, a module for detecting an active virtual server, and a module for switching the correspondence of boot disks of virtualization modules for controlling virtual servers to the physical servers. When a physical server fails, the boot disk of the associated virtualization module is connected to a spare server to automatically activate on the spare server those virtual servers which have been active upon occurrence of the failure.

A deploy target computer is connected to a storage device including a replication source logical disk used to store a boot disk image. A disk mapping processing part in the deploy target computer changes over access destination so as to set the access destination to the replication source logical disk in the storage device when an I/O request is issued from the deploy target computer to the storage device and the I/O request specifies reading the boot disk image, and so as to set the access destination to a replication destination logical disk for conducting writing concerning the boot disk image when the I/O request specifies writing concerning the boot disk image.

The invention comprises a method and apparatus for the remote installation of software from one or more central locations to a plurality of remote machines. A centralized database, remote to the user, is maintained that includes characteristics of users and/or their machines. An image of a computer program, such as an operating system, is maintained at a location that is remote to the user/machine. Image information is accessed from within the database to configure the program. The image is downloaded to a destination machine on a medium that also includes a utility for installing the image at the destination machine. The medium is used to install the program at the destination, and automatically configures the program using configuration settings that are also imaged on the medium, and that are maintained at the database. Thus, a boot disk is provided that is only used for the installation process.

The present invention enables to update a program in a storage control device while processing access requests, without imposing any burden on a host. When execution of updating of a program is commanded from a management terminal, an update control unit starts within the controller which is the object of updating. After a host I/F unit has been connected to an access request processing unit within another controller by a connection control unit, the update control unit updates a program which is stored in a program memory or a boot disk. When this updating is completed, the update control unit reconnects the host I/F unit to its access processing unit by the connection control unit. Since the stored contents of data memories are synchronized, the other access request processing unit can continue processing access requests from the host in place one access request processing unit.

The invention discloses a method and a device for establishing a storage cache shared by virtual machine. The method comprises the steps of: obtaining data reading (writing) from a virtual boot disk when a virtual machine is starting, and storing the data into a shared cache device of the virtual machine, and thus other virtual machines can read the data from the shared cache device of the virtual when starting. By the adoption of the above manner, very little space is used for caching only effective data in the starting of the virtual machine, and thus the input and output problem when the virtual machines read and write the data concurrently.
