TL;DR: In this paper, a file server system appears to the host computer to be a plurality of data storage devices which are directly addressable by the host computers using the native data management and access structures of the host Computer.
Abstract: This file server system appears to the host computer to be a plurality of data storage devices which are directly addressable by the host computer using the native data management and access structures of the host computer. The file server however is an intelligent data storage subsystem that defines, manages and accesses synchronized sets of data and maintains these synchronized sets of data external from the host computer system's data management facilities in a manner that is completely transparent to the host computer. This is accomplished by the use of the snapshot application data group that extends the traditional sequential data set processing concept of generation data groups.

TL;DR: In this paper, a physical switching device for use in a communication network to switch Open Systems Interconnection (OSI) network layer packets and method of use therefor is provided.
Abstract: A physical switching device for use in a communication network to switch Open Systems Interconnection (OSI) network layer packets and method of use therefor is provided. The physical switching device includes at least a first and a second virtual switch. Each virtual switch includes a decision mechanism for determining an associated directive based on a destination identifier within a particular packet received at a data port. A processor is coupled to each virtual switch to insert the particular packet into an outgoing data stream on another data port to deliver the packet. Both data ports are associated with a plurality of data interfaces in the physical switching device. A management apparatus is coupled to each virtual switch to maintain information on an association between the plurality of data interfaces and the virtual switches. The management apparatus limits each processor to only inserting the particular packet on another data port associated with the same virtual switch which received the particular packet.

TL;DR: The Network Storage Manager (NSM) as discussed by the authors is a set of software components, the NSM controller contains a plurality of software elements including: Resource Allocation, Resource Configuration, Resource Management and Security Management modules.
Abstract: This data storage subsystem creates multiple virtual storage devices on demand, which are available to any and all of the system's host data processors. The subsystem utilizes a plurality of tape devices and automated tape libraries with the tape devices connected to a plurality of data processors via a high-speed network. A set of software components, the Network Storage Manager (NSM) controls all system operations. Depending upon the requested storage performance, one or more tape devices are assigned to a virtual device. Data stripping across multiple tape devices allows the storage bandwidth of a virtual device to be changed on demand. The overall capacity and performance of the subsystem is scalable by adding or removing storage devices. The NSM system controller contains a plurality of software elements including: Resource Allocation, Resource Configuration, Resource Management, and Security Management modules. The use of a networked storage manager enables the storage devices to be managed as a pool and yet be attached directly to the network as individual resources. The NSM also provides the mechanism for the enterprise management to control tape device allocation and configuration as well as other functions, such as tape cartridge movement, data migration and data security.

TL;DR: The disk drive memory of the present invention uses a large plurality of small form factor disk drives to implement an inexpensive, high performance, high reliability disk drive memories that emulates the format and capability of large form factor disks.
Abstract: The disk drive memory of the present invention uses a large plurality of small form factor disk drives to implement an inexpensive, high performance, high reliability disk drive memory that emulates the format and capability of large form factor disk drives. The plurality of disk drives are switchably interconnectable to form parity groups of N+1 parallel connected disk drives to store data thereon. The N+1 disk drives are used to store the N segments of each data word plus a parity segment. In addition, a pool of backup disk drives is maintained to automatically substitute a replacement disk drive for a disk drive in a parity group that fails during operation.

TL;DR: In this paper, a system for object-based archival data storage includes an objectbased storage subsystem having respective data storage devices, at least one file presentation interface that interfaces to client platforms, an administration interface having graphical user interface (GUI) and a command line interface (CLI), a meta data subsystem for storing meta data about files, and an virtual file subsystem having a virtual file server (VFS), a policy subsystem, and a scalar e interconnect.
Abstract: A system for object-based archival data storage includes an object-­based storage subsystem having respective data storage devices, at least one file presentation interface that interfaces to client platforms, an administration interface having graphical user interface (GUI) and a command line interface (CLI), a meta data subsystem for storing meta data about files, and includes a virtual file subsystem having a virtual file server (VFS), a policy subsystem, and a scalar e interconnect to couple the object-based storage subsystem, the at least one file presentation interface, the administration interface, the meta data subsystem, and the policy subsystem, wherein the policy subsystem provides system rules predetermined by a user for at least one of hash based integrity checking, read­-only/write-ability/erase-ability control, and duplicate data treatment corresponding to files and file objects.
