GDPS is IBM’s most advanced Business Continuity solution for the zSeries platform. Its design leverages the availability of enough data processing components in multiple sites, such that IT services may continue even if one site suffers a complete failure. All critical data, disk or tape resident, is mirrored between sites using synchronous and/or asynchronous remote copy.
GDPS is about maximizing availability. However, as those in both performance and business can attest, availability is not always a binary event (such as a disaster). For example, if critical data is available on your Disk Subsystems but poor I/O response times are impacting your applications, are you meeting your availability objectives? The data storage and data replication involved in these types of environments is complex, and this is magnified by the difficulty of seeing how it is operating.
Our latest technical note, “IntelliMagic Vision in GDPS Environments” covers how IntelliMagic solutions provide visibility into this highly valuable and critical infrastructure with more built-in intelligence and predictive capabilities than any other solution on the market. Topics covered include:
- Automated Storage Infrastructure Health Check
- Synchronous Replication
- Asynchronous Replication
- Global Mirror for zSeries (zGM aka XRC)
- Inter-Site Bandwidth Requirements
- 3-Site and 4-Site Solutions
- GDPS Active-Active
- Balanced I/O Load
- Monitor Primary and Ancillary Disk Subsystems
- Monitor PPRC and XRC Links
The automatic health checks and additional metrics reduce risk and help avoid performance related outages. Customer experience with IntelliMagic Vision at GDPS sites demonstrates that the same drivers of reducing the risk of availability issues also apply to the adoption of IntelliMagic Vision.
IntelliMagic Vision in GDPS Environments
This IntelliMagic Technical Note provides a brief overview of how IntelliMagic Vision complements IBM’s Geographically Dispersed Parallel Sysplex (GDPS) solution.
Don’t Let RPO Knock Your SOX Off!
Proving that you maintain control of your recovery point objective (RPO) is key for SOX compliance if you use asynchronous replication to protect your data.
IBM z15 Announcement Highlights and How to Take Advantage
The z15 (with a General Availability date of 9/23/2019) offers up to 190 CPU cores (vs. 170 on z14) and 40 TB of usable memory (vs. 32 on z14), in addition to processor cache and overall performance improvements.
CPU – Just the Tip of the z/OS Iceberg
z/OS is now responsible for everything from online transactions, network traffic, replicated data, and so much more. The infrastructure to handle this complexity is no longer limited to ensuring CPU is going to be okay.
