DEC-StorageArrayFamily

The Digital Storage Array Family offers architecturally compatible, high-performance, and high-capacity storage solutions designed for VAX computing, delivering "mainframe storage in a minicomputer footprint."

Key aspects of the family include:

• Optimized Footprint: Maximizes computer room floor space, offering a wide range of capacities (1.8 to 9.7 gigabytes) within a compact design.
• Performance & Capacity: Leverages Digital's fastest, most reliable, and highest-capacity RA-series disk drives. Mixed Storage Arrays (SA650, SA550) combine different drive types (e.g., RA90, RA70, RA82) to optimize for both high-performance access and large storage requirements, minimizing I/O bottlenecks.
• Reliability & Availability: Built for state-of-the-art reliability, maximum system availability, and data integrity. This is ensured through extensive testing, conformance with Digital Storage Architecture (DSA), and tools like VAXsimPLUS for predictive maintenance and automatic fail-over. The products come with a one-year warranty.
• Investment Protection: Full conformance with Digital Storage Architecture (DSA) and Standard Disk Interconnect (SDI) guarantees compatibility with existing Digital I/O servers, controllers, and VAX/PDP systems. Storage Array Building Blocks (SABBs) allow for easy, non-interruptive field upgrades and expansion.

The family includes models like the SA650 (premium capacity/performance), SA550 (performance boost/investment protection), SA600 (optimal footprint/high capacity), and SA482 (entry-level mainframe storage), all designed for ease of ordering, configuration, and servicing.
