This volume (Volume 6, Number 4, Fall 1994) of the Digital Technical Journal contains three primary computing topics:

1. RAID Array Controllers: Details the architecture and design of the HS-series StorageWorks array controllers, focusing on high availability (dual-redundant configuration), performance (caching and RAID), and the common hardware platform.
2. Workflow Models: Discusses the Policy Resolution Architecture (PRA), which separates workflow specifications from task assignment policies to enable enterprise-level workflow deployment.
3. PC LAN and System Management Tools: Covers the design of ManageWORKS (a user interface framework for system and network management), the OpenVMS Management Station, and the POLYCENTER Software Distribution's initial system load (ISL) process for network-directed software upgrades.
