HPE NonStop Review

Valuable features include fault-tolerant transaction processing and reliability.


Valuable Features

  • Rock solid reliablity
  • 99.9% uptime
  • Fault-tolerant transaction processing

Improvements to My Organization

Retail payments must be reliable with high uptime.

Room for Improvement

NonStop (formerly known as Tandem) in the Guardian OS could use another, friendlier macro language. The one provided (TACL) is a bit cumbersome - and there are not practical alternatives available.

Use of Solution

I've used it for 12 years.

Deployment Issues

There was no issues with the deployment.

Stability Issues

This is why stock markets use it for transaction processing. Stability is what NonStop Tandem is famous for.

Scalability Issues

You can't exceed the scalability available.

Customer Service and Technical Support

Excellent. Tech support is always, repeat always, a seasoned expert engineer.

Previous Solutions

I have worked on NonStop my entire career.

Initial Setup

Relatively challenging, for example it was difficult to configure the communications.

Implementation Team

We used a vendor team.

Pricing, Setup Cost and Licensing

If you have a high transaction volumes, it can be justified. If your transaction volumes are ordinary, this may be way too much machine for your needs. Think five million retail transactions monthly, as an example.

Other Advice

If you are contemplating a fault-tolerant, high uptime transaction processing machine with above normal transactions volumes - to act as a transaction server with infrequent changes to code - and you simply must have bulletproof performance - this might be the ticket. And if it is, spend a little time checking into the flavors: original Guardian OS, or the Unix OSS. Primarily languages used are TAL, C, and, yes, Cobol.
