According to recent estimates, more than 60% of the data in the world is stored in some form of database. If you consider that at least 75% of that data is infrequently or never accessed, this means that roughly 45% of the world’s data is inactive and unnecessarily using database resources.For smaller databases, simply storing the entire database on a RAID array is usually feasible in cost and performance.

However, industry experts agree that databases may grow to over a petabyte in size in the next two to five years as a result of continual, almost exponential growth in the amount of data stored worldwide (Data Warehouses, CRM solutions). It is already common in many industries to find databases ranging in size from hundreds of gigabytes to several terabytes.

SANity™ DB NAS provides an easy administrative interface with which to configure and manage the process of selectively and transparently moving inactive data from on-line databases to more cost effective optical media (DVD).

The solution

SANity™ DB NAS takes the load off your production servers and provides non-volatile, long-term archival for transactional and business data, while the near-line archived data remains available and can be accessed and queried.

SANity™ DB NAS enables you to selectively replicate and archive data from even geographically distant databases within your organization. This near-line archive becomes a centralized repository for your important business data.

Features and avantages

• Write protected DVD system ensures the safe recording and storage and protects against external effects and/or sabotage.
• Multiple DVD Storage units can be connected to multiple servers.
• Mirroring – Duplication of your data can be accomplished within a singe DVD Storage and/or between devices.
• Open, standards based solution which can easily be configured to work with other systems.
• Reliable, hands-off operation.
• Multiple copies of the data can be created, even in different geographical locations.
• Highly scalable solution with schedulable, transparent archival.
• The DVD Storage can also be used as a NAS fileserver.
• Distributed architecture - the servers communicate using a solution built on standard CORBA.
• The same data can be simultaneously accessed by a separate OLTP or DSS system.

The system is composed of 3 major subsystems

The SANity™ DB NAS system is composed of distributed, intercommunicating Java components. With the aid of this system, a system administrator can move read-only elements in the given system to the archive and make them accessible to other systems, transfer these elements between databases, mirror archived data and create backups.

• Host Device component
• Manager component
• Archive device component
