COT offers a number of services associated with the storage and retrieval of data stored on disk (DASD), SAN (Storage Area Network) and NAS (Network Attached Storage) and tape media. These offerings will cover everything from mainframe storage and backup to the backing up of data stored at remote sites. This allows the agency to choose the most cost effective solution for their backup and storage needs.
Disk storage is available for the mainframe, UNIX and Wintel server platforms, and is charged back to customers each month based on the total number of megabytes of storage used. The data center's tape storage is billed to customers by actual usage, when the tape is written or read, rather than by the utilization of tape storage media.
Robotic tape libraries are used for the data center's automated tape processing and are monitored for hardware and software problems. Costs normally associated with tape storage such as tape cartridge costs, hardware costs, maintenance fees, floor space, utilities and insurance, are included in COT's tape storage rates.
Tivoli Storage Manager (TSM) software is used at the data center for backup and recovery by storing, archiving and restoring data, space management, and for maintaining compliance and disaster-recovery data in a hierarchy of offline storage. Because it is highly scalable, Tivoli Storage Manager can protect servers running a variety of different operating systems, from Wintel servers to mainframe computers, connected together through the Internet, wide area networks (WANs), local area networks (LANs) or storage area networks (SANs).
