SDJ / STJ

In combination with Data Director, SDJ / STJ can simultaneously mirror archive data on magnetic disk storage (RAID, NAS, CAS) and to a secure optical or tape library. This provides very fast access to archive records from disk storage with secure retention, and an extra level of system resilience mirroring to optical or tape. SDJ / STJ was designed specifically for archive environments that demand the security and flexibility of removable optical or tape media, but also require magnetic disk access performance.

SDJ / STJ support virtual library volumes on local RAID systems. Using a secure, real-time transaction logging cache, SDJ / STJ transparently mirrors data across disk and library storage devices providing a simultaneous exact copy of all data at two locations. An SDJ / STJ configuration improves access performance to the archive, reduces down time, and enhances system resilience as part of a 3-2-1 archive strategy.
