HPE NonStop Review

Valuable features include fault-tolerant transaction processing and reliability.

What is most valuable?

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

How has it helped my organization?

Retail payments must be reliable with high uptime.

What needs 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.

For how long have I used the solution?

I've used it for 12 years.

What was my experience with deployment of the solution?

There was no issues with the deployment.

What do I think about the stability of the solution?

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

What do I think about the scalability of the solution?

You can't exceed the scalability available.

How are customer service and technical support?

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

Which solution did I use previously and why did I switch?

I have worked on NonStop my entire career.

How was the initial setup?

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

What about the implementation team?

We used a vendor team.

What's my experience with 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.

What other advice do I have?

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.
