Capacity: 60/180GB WORM (native/compressed)
Data cartridges for the IBM TotalStorage Enterprise Tape Drive 3592 are available in rewritable and WORM formats in 300GB or economy 60GB capacities. They are supported in many IBM and StorageTek tape automation solutions.
The first-generation 3592 J1A tape drive can initialize short length JJ cartridges to 60GB and initialize (or re-initialize) standard JA length cartridges to either 60GB (to support fast time to data) or 300GB (to support high capacity).
The second-generation TS1120 tape drive can initialize short length JJ cartridges to 60 or 100GB and initialize (or re-initialize) standard length JA cartridges to 60, 100, 300 or 500GB to support fast access to data or to help address data growth and facilitate interchange. At typical compression ratios, the 3592 JA cartridge can provide usable capacity of up to 1TB in an open system environment, and up to 1.5TB in an IBM System z9™ environment when used with a TS1120 Tape Drive. The JA and JJ cartridge models are suitable for storing data that has a finite life span and are rewritable.
The TS1120 and 3592 J1A tape drives are designed to work with Write Once, Read Many (WORM) JR and JW cartridges to store data in a non-erasable, non-rewritable format. This is intended to help support the long term retention of reference data and meet the requirements of regulatory bodies worldwide. The short length JR and standard length JW cartridges have advanced security features that are designed to prevent the alteration or deletion of stored data while allowing data to be appended to existing cartridges or files.
Special grip points and a form factor that is similar to the IBM TotalStorage 3590 cartridge models allow the 3592 cartridges to co-exist in either an IBM TotalStorage Enterprise Tape Library 3494 or a StorageTek 9310 Powderhorn Tape Library. The 3592 cartridges can also co-exist in an IBM TotalStorage Tape Library 3584 with IBM TotalStorage Ultrium™ LTO™ tape cartridges. This may reduce the physical tape resources and number of cartridges needed to support the environment and help reduce the cost of ownership.
The IBM 3592 tape cartridge contains an advanced fourth-generation metal particle formulation in a dual layer coating on a half-inch-wide tape. The IBM tape uses an advanced magnetic coating and process designed to provide a high output and signal quality to support the current TS1120 and 3592 J1A tape drives. The tape features an ultra-smooth and uniform magnetic layer less than 0.2 microns thick and a specially refined coating formulation designed to help improve media reliability and performance as well as minimize wear of the tape heads and components. A precision timing-based servo with enhanced features helps enable high track densities, high data rates and data access performance as well as high reliability and stop-start performance. In addition, modifications to the cartridge design and construction are designed to help improve pin retention, hub and clutch engagement, spool alignment and tape stacking within the cartridge. These enhancements are designed to help improve reliability and durability of not only the media, but of the tape drive as well.
A cartridge memory chip that stores access history and media performance information is built into every cartridge. Records are written to the memory chip every time the cartridge is unloaded from a TS1120 or 3592 J1A tape drive. These records can be used by the IBM Statistical Analysis and Reporting System (SARS) programs to analyze and report on tape drive and cartridge usage and help diagnose and isolate tape errors. SARS can also be used to proactively determine if the tape media or tape drives are degrading over time.
