A description is presented of network components, their interaction and some of the efforts to ensure security. The NWC network is a computer network that will allow the facilities to exchange, store, and manage shared information. The networking and storage capabilities are enhancements of systems available from commercial sources and from specific systems in use at Los Alamos National Laboratory.<<ETX>>","PeriodicalId":156527,"journal":{"name":"Digest of Papers Ninth IEEE Symposium on Mass Storage Systems, 1988.

Magnetic disk storage is used on an IBM plug-compatible mainframe to store the indices. Optical storage which offers the best cost/performance ratio, is used to store the images of the patents. Two types of optical storage devices are used: the removable optical disk and the jukebox. Removable optical disks have a relatively fast access time and therefore they are used to store the most frequently accessed patents. The jukeboxes have a relatively slow access time and are used to store the remainder of the patents. Both the removable optical disks and the jukeboxes are controlled by Unix supermicrocomputers such as the SUN-3. The intelligent controllers contain cache magnetic storage for matching the data transfer speed of the optical drives with the network. All of the removable optical disks and jukeboxes are connected together using packet-switching digital switches which offer an off-the-shelf IEEE 802.3 network with guaranteed end-to-end throughput. >","PeriodicalId":156527,"journal":{"name":"Digest of Papers Ninth IEEE Symposium on Mass Storage Systems, 1988.

A discussion is presented of the strategy used in developing an effective management policy for the movement of files between the disk farm and tape library, the algorithms chosen, the mechanisms implemented for tuning those algorithms, and the effects on system performance experienced as a result. >","PeriodicalId":156527,"journal":{"name":"Digest of Papers Ninth IEEE Symposium on Mass Storage Systems, 1988.

The system uses a robot which moves optical disk cassettes to and from three read/write units. The software was designed to make the system very easy to use. The users or clients see the system as a large file server, and see the system as a single 2 terabyte (16 TB) volume with a 1 gigabyte file-length limitation. Thus the users concern themselves only with filenames and not with cassette numbers or track numbers. The system is automatic and available 24 h/day, seven days a week to a community of scientists in many university departments. The users pay for their use and can choose between the OAS, centralized magnetic disk systems, their own magnetic disks, and various magnetic tape systems. Use is voluntary, and the users make their choice in terms of the perceived values and perceived costs.<<ETX>>","PeriodicalId":156527,"journal":{"name":"Digest of Papers Ninth IEEE Symposium on Mass Storage Systems, 1988.
