8464ch09_Oper.fm Draft Document for Review February 7, 2020 3:15 pm For more information about achieving peak network performance, see  IBM Virtualization  Engine TS7700 Series Best Practices - Understanding, Monitoring, and Tuning the TS7700  Performance , WP101465. Cache utilization statistics are presented for clusters that have a cache single partition and for  clusters with cache with multiple partitions. Models TS7760 or TS7770 disk-only clusters  have only one resident partition, which accounts for the entire cache.  For the TS7700T (tape attach) or TS7700C (cloud attach) cluster model, up to eight cache  partitions (one CP0 cache resident and up to seven partitions) can be defined and  represented in the cache utilization window.  Note:  Enabling (and configuring) the DS8000 object store feature (FC 5282) creates an  object partition. For more information about planning and implementing the function of using the TS7700  as an optional target for DS8000 Transparent Cloud Tier using DFSMS see: Cache utilization GLYPH<SM590000> IBM TS7700 Series DS8000 Object Store User’s Guide Version 1.0 , REDP-5583 GLYPH<SM590000> IBM DS8000 and Transparent Cloud Tiering , SG24-8381 Figure 9-33 shows an example of cache utilization in a single partition cache, as in a  TS7700D cluster. The Cache Partition window presents the cache use statistics for the TS7700T or TS7700C  models, in which the cache is made up of multiple partitions. Figure 9-34 on page 386 shows  a sample of the Cache Partition (multiple partitions) window. This window can be accessed by  clicking the  Monitor  icon or by clicking the  Virtual  icon. Both methods direct to the same  window. In this window, the user can display the existent cache partitions, create or  reconfigure a partition, or delete a partition as needed.
