The TS7CDT query generates a daily chart for Cluster 0 of each IBM TS7700 Grid. The chart shows, for each hour, the amount of data written by workloads to cache, and the amount of data copied to the high availability Cluster 1. The chart shows megabytes written to cache using a vertical bar and the data copied to Cluster 1 using a horizontal line. Both values represent data that was compressed by the Host Bus Adaptors (HBAs).
The example shows the chart generated for Grid 00100, Cluster 0 of an IBM TS7700. For hours 0 through 12, more data was written to the cache than was copied to Cluster 1. As the incoming data rate decreased, in hours 13 through 23, the data copy volume exceeded that written to cache.
