Storage Array Family

The Digital Storage Array Family provides integrated storage solutions designed for VAX computing. The family includes the SA650, SA550, SA600, and SA482 models, all of which utilize a compact, standardized footprint for mainframe-level storage. These systems offer:

• Flexibility and Scalability: Available as Storage Array Building Blocks (SABBs), allowing for field upgrades to increase capacity and performance without system downtime.
• Performance: Utilization of advanced RA-series disk drives, including dual-port support, to minimize I/O bottlenecks and maximize throughput.
• Reliability: Incorporates VAXsimPLUS for predictive maintenance, extensive error detection and correction (170-bit ECC), and hot-swappable/modular field-replaceable units (FRUs) to maintain high system availability.
• Compatibility: Adherence to the Digital Storage Architecture (DSA) and Standard Disk Interconnect (SDI), ensuring compatibility across Digital's VAX and PDP processor lines and I/O controllers.

The document also provides comprehensive technical specifications, including capacity, power, performance, and physical environment requirements for the entire array family and individual component drives.
