Patton LLC(I.T/Industry/Military)
The company of Patton LLC:We make it easy for companies around the world to connect their people and things in a perpetually changing technology landscape,As a long-lasting technology company Patton has seen and participated in the many changes of technology and markets. Patton lives in the change. Incorporated in 1984, we have designed and built everything from connectivity devices that connect "this-with-that", to carrier-grade Telecom equipment that connects subscribers to service providers. Patton's specialty is interconnecting yesterday's cutting edge to the cutting edge of today.
The features of Patton LLC :
Mirror writing eliminates the risk of data loss associated with a media failure. Tape and optical media is manufactured to very high standards but a media failure is still a possibility. If this were to happen, data could be lost. Typically, most administrators would create a second copy of data on another piece of media and remove it from the library, providing a disaster recovery copy.
Data Director provides a better solution. The software uniquely creates two synchronous mirrored copies, eliminating any issues associated with bad media. With Data Director 1, once both the primary and secondary media copies are full, the second can be removed and transported to an offsite location. In this way only a single copy is retained in the library, optimizing storage capacity.
DDR2 is mainly to mirror data to two different storage libraries. It’s important that these two libraries must use the same capacity media and technology. As the following picture shows, the storage library 2 can contain fewer hard drive slots with additional media removed and kept off-line.
DDR2 is more efficient than DDR1; when it breakdowns, user can still access into their database. When the software detects a simulated media failure, user can still write/mirror data to other well functional storage library. Once the repaired device reconnects, Data Director will automatically synchronize the data of two locations.
Data director 3’s feature is 2 servers and 2 libraries mirroring 2 media sets. Like DDR2, these two libraries must use the same capacity media and technology. As the following picture shows, the storage library 2 can contain fewer hard drive slots with additional media removed and kept off-line.
The difference between DDR1, 2 and DDR3 is that user can put storage libraries into two different locations. DDR3 uses WAN to back up data across multiple geographic locations. DDR3 is also more efficient than DDR1 in mirroring data. User can still access to database when it breakdowns. When the software detects a simulated media failure, user can still write/mirror data to other well functional storage library. Once the repaired device reconnects, Data Director will automatically synchronize the data of two locations.
Primary mirror on RAID uses simulated media. And, the storage library 2 can contain fewer hard drive slots with additional media removed and kept off-line.
