IT news and products; 'Diskless' server technology.Ultraspeed has launched its Diskless Server System (DSS (1) (Digital Signature Standard) A National Security Administration standard for authenticating an electronic message. See RSA and digital signature. (2) (Digital Satellite S )--a hosted platform to remove hard disks, the primary cause of failure, from customer servers. The DSS platform uses a 'storage area network' (SAN) to provide the operating system operating system (OS) Software that controls the operation of a computer, directs the input and output of data, keeps track of files, and controls the processing of computer programs. , applications and data storage. DSS claims to bring new levels of reliability to the hosting market by effectively eliminating the single biggest cause of individual server failure--a defective hard disk--and means that organisations can be confident that business-critical data will always be available. Ultraspeed's DSS servers 'boot' from the SAN via gigabit Ethernet An Ethernet standard that transmits at 1 Gbps. Used mostly to connect high-end workstations and servers as well as for network backbones, Gigabit Ethernet transmits full duplex from point to point using switches and half duplex in a shared environment (CSMA/CD) using a hub. connections. All data is continually replicated across the SAN, and should an individual SAN hard disk fail, it is swapped out swapped out - swap and the replacement is automatically populated pop·u·late tr.v. pop·u·lat·ed, pop·u·lat·ing, pop·u·lates 1.

This approach is in stark contrast to traditional server environments in which hard disk failure can result in the server being 'knocked out' completely whilst the disk is replaced and re-populated with data from the last backup. In addition to the DSS's inherent backup and recovery systems, the platform provides significant additional benefits to an online community increasingly reliant on data integrity and speed of access. Customer servers are automatically "snapshotted" on a daily basis by the DSS, to enabling a fast rollback to that particular time-point should the need arise. The DSS platform can perform 100,000 disk operations per second, whilst the average fibre channel local disk based (1) Refers to devices that use magnetic hard disks for storage.
