Although modules could be loaded separately, they were only replaced in the lab, never in the field. The system more closely resembled one executable with threads, with its configuration data normally write-protected. It had hitless patching in the early 1980s, and that's how bug fixes were delivered to in-service sites.

CPUs were paired, running under either hot (hardware checkpointing) or warm standby (software checkpointing), with failover. Both have drawbacks when recovering from serious errors; the real advantage of pairing is that a new software release can be installed, with no outage at all, by
  • dropping synch
  • loading the new software into the inactive unit
  • resynching (always software checkpointing)
  • making the inactive unit active
  • upgrading the remaining unit
  • resynching the just-upgraded inactive unit
Applications were stateful. None of this lame stateless shite that is currently in vogue for web apps. There simply wasn't enough CPU power or disk bandwidth to commit after every transaction and reload before handling the next one.

The first trials were in the late 1970s, after which new capabilities were continually added. The system is still in widespread use some 40 years later.
