The SA482 is a 2.5-Gigabyte storage array developed by Digital Equipment Corporation, designed as a complete storage solution for large VAX and VAXcluster systems.
Key Features and Benefits:
- Architecture: Built upon the Digital Storage Architecture (DSA) and Standard Disk Interface (SDI), ensuring investment protection, ease of maintenance, high data integrity, availability, and performance. DSA allows for easy integration of new mass-storage products without software or hardware changes, and offloads I/O control functions from the host.
- Capacity: Provides 2.5 gigabytes of user-accessible data storage (3.4 GB unformatted), offering a high-density, cost-effective solution with 452 megabytes per square foot.
- Performance: Features multipath, multispindle capabilities with four independent spindles, delivering a peak transfer rate of 2.4 MB/second/spindle and 24 milliseconds average seek time. It emphasizes optimal I/O subsystem performance through sophisticated controller optimization algorithms.
- Flexibility: The SDI's radial connection allows individual drives to be serviced without shutting down the entire subsystem, minimizing downtime. It's plug-compatible with various SDI I/O servers (HSC70, HSC50) and controllers (KDB50, KDA50, UDA50), allowing flexible configurations for capacity, redundancy, and performance.
- Reliability & Support: Comes with a one-year warranty backed by Digital's Field Service Organization, known for its rapid response times. Digital also provides supporting services like Software Performance Monitor (SPM) and educational workshops to help users optimize their storage capabilities.
