grid (Clustered) SAN cipher standards - Essay Example2. A storage system which consists of interlocking elements such as storage devices, computer systems, servers, control software (such as server administration and situation server) that forget communicate over the interlocking.Storage networks are distinguished from otherwise forms of network storage devices scarcely by their low-level access method they use and is very similar to such network devices as ATA, disk drives and SCSI hardware. Inside a storage network, the server depart issue a necessitate for specific blocks of data and this device on the storage network will then send requests crossways the network.In the clustered grid infrastructure would be a series of SAN devices that would then integrate as part of the larger network in baseball club to share the storage capabilities within the GRID. As such, apiece device would then be added to the larger network that can be used by other networked devices such as a computer workstation. An example of this computing infrastructure, courtesy of Force10, shows how this cluster/GRID computing network is positioned to utilized these storage devicesGRID computing is the transformation of a computer infrastructure into an incorporate Virtual Organisation that allows for dynamic collaboration and the ability to share resources from anywhere in the world. This sharing provides users with an unique amount of computing power, especially for those in the field of scientific investigation and collaboration in which the inevitably of the computer power cannot necessarily be handled by one such computer. Through integration inside the GRID of such supercomputers will enable users to access power without the need to purchase larger systems.GRID computing is based on three concepts as outlined by Reddy (2004) asVirtualization severing the hard-coded connection of resources to systemsResource Allocation and Management dynamically allocating resources o n demand, and managing them and finally,Provisioning configuring resources whenever and wherever needed. (Reddy, 2004)Kalzar Amin, Gregor von Laszewski and Armin R. MiklerKalzar, et al describe the term grid computing as commonly referred to a distributed infrastructure that promotes large scale resource sharing in a dynamic institutional virtual organisation (VO). A computational Grid forms a unsympathetic network of a large number of pooled resources providing standardized, reliable, specialized and pervasive access to high-end computational resources.Typically, in order to establish a computational Grid, several institutions pool their resources such as computational cycles, specialized software, database servers, network bandwidth, and people. As a result of this pooling global policies will be set for the virtual organisation which will in an essence identify each of the participating entities roles and responsibilities, much like in a local area network server networking sce nario. Each of the site institution administrators, who are generally trained as network administrators will then enforce these policies at the domain level. The GRID administrators will then provide each of the GRID users their appropriate credentials and through these credentials will the users access
