How to Find Sick But Not Dead (SBND) TS7700 Tape Clusters
Rather than waiting for a remote VTS to fail, you should be reviewing these key TS7700 reports to determine if remote clusters are receiving replication data or not.
4 Benefits of Implementing TS7700’s New Microcode Compression
Implementing the TS7700 microcode-based compression algorithms can have benefits beyond better compression. The CPU algorithms allow host jobs to run faster and improve replication time.
6 Reports Every IBM TS7700 Performance Analyst Should Have
Rather than reviewing every indicator across your entire tape grid, there are 6 key reports that you should be reviewing regularly to keep your TS7700 in good working order.
