Storage
The predominant storage method today is hard disks directly attached to servers. The disadvantage of this primitive method, is there never seems to be enough hard disk space where you need it, too much in other places, and knowing your data is backed up reliably is a major challenge. Networked data is becoming increasingly mission critical and users are demanding access to it any place and any time.
A storage network involves the removal of storage devices (like hard disks and tapes) from servers and placing them on the network. This allows for much greater flexibility of storage assets like hard disk space which for the first time can be easily moved between servers, and extra space can easily be added as needed. Not only are backups simple and fast, but data is now readily availability.
Understanding what must be managed is only part of the overall task facing IT professionals. A very specific set of disciplines must be put employed to assure successful planning, deployment and maintenance. As a general rule the following management tasks and skills need to be addressed:
- Deployment management – change management, configuration management and capacity planning
- Compliance management - a structure that includes fault monitoring, performance monitoring, trend analysis, quota management and accounting management for billing (if necessary)
- Service management – ensures that thresholds are defined, implementing backup and archives, disaster recovery planning and security management
Given the fact that storage has always been a central concern for business, any technology that simplifies operations and saves money understandably generates great interest.
