2.1 Gdps May 2026

The "2.1" moniker often confuses buyers running IBM i 7.4. The name persists for legacy compatibility, but the feature set requires IBM i 7.2 TR3 or later. Specifically, the SST (System Service Tools) commands WRKDSKSTS and the disaster recovery APIs were enhanced in 7.2 to report back to GDPS about journal latency.

| Includes | Excludes | |--------------|---------------| | Final goods & services | Intermediate goods (to avoid double counting) | | Housing services (imputed rent) | Unpaid household labor (childcare, cleaning) | | Government services (valued at cost) | Underground/black market activity | | Inventory changes | Sales of used goods | | | Financial transactions (stocks, bonds) | | | Environmental degradation |

Implementing 2.1 GDPS is not inexpensive. You will need:

That said, for a bank processing 10,000 transactions per second on IBM i, the cost of a single hour of downtime ($1M+) pays for the solution within a single incident. 2.1 gdps

To sustain such a rate without excess volatility, policymakers should prioritize:

The Federal Reserve’s “soft landing” in the mid-1990s (2.3% average from 1993–1999) demonstrates that 2–2.5% growth can coexist with low inflation and falling unemployment when combined with technological tailwinds (the internet boom).

The shift to 2.1 GDPS represents a fundamental shift from analog thinking to digital precision. If your quality control department is still using legacy filters, you are effectively measuring the past, not the present. You are introducing phase errors that hide defects and inflate scrap rates. The "2

For engineers, the call to action is clear:

In the race for miniaturization, durability, and performance, the difference between a good part and a failed part is measured in nanometers. The 2.1 GDPS standard ensures that what you measure is what you actually get.

Stay precise. Stay compliant. Update to 2.1. That said, for a bank processing 10,000 transactions

The real genius of 2.1 is three-site replication. You can configure Metro Mirror (synchronous, <10km) between Data Center A and B for zero data loss, while simultaneously sending Global Mirror (asynchronous) to Data Center C (over 300km away). GDPS 2.1 automates the promotion of the Global Mirror copy to a Metro Mirror role during a failover.
