Data grids for storage

Current grid computing projects manned mostly by scientific teams offer some tantalizing prospects for general corporate computing. Imagine making your organization's data accessible throughout the world or replicating data to multiple, geographically dispersed sites--even sites you don't own or control, but with which you collaborate. If you use traditional access-control methods, the barriers to this scenario are substantial. You could, for example, set up replicated Web FTP mirror sites with user logins and passwords to all of the sites providing access, or set up VPN access to each site holding the data. Open-source grids Globus is the progenitor of many of today's grids. The Globus Alliance and the Global Grid Forum (GGF) support the Globus Toolkit, and have developed some of the fundamental services required to implement a grid. The GGF is also charged with popularizing the grid by making it easier for all users to participate in grid work. There are essentially three different modes of Globus support software: the ...

Features in this issue

  • Hidden threats to data

    Inadequacies in storage governance and weaknesses in data management may pose far less-visible risks to a company's data. To mitigate these threats, you must be aware of the impact and probability of these risks to reduce or eliminate them.

  • Safer SATA for nearline apps

    New SATA drivers tailored for nearline apps

  • Keep remote offices in sync

    With regulatory compliance, data protection requirements and the need to share data, remote office data can no longer be ignored. Wide-area file system products can rein in and protect remote data.

  • Will your disaster recovery plan work?

    No matter how many checklists a company creates, the number of disaster scenarios it considers or even how assiduously it backs up data, managers can't be confident in their firm's ability to recover data unless the systems have been tested thoroughly.

  • Better capacity forecasting

    There are two methods for devising storage capacity forecasts: quantitative and qualitative. By combining the two, you can develop practical metrics that will make more accurate forecasts.

  • Data grids for storage

    Data grids are used by the scientific community to access data resources around the world. Companies can use the principles underlying these global grids to link geographically dispersed sites.
