The IBM Storage Tier Advisor Tool predicts whether the addition of Solid State Drive (SSD) capacity in conjunction with the Easy Tier function could benefit system performance.
The IBM Storage Tier Advisor Tool is a Windows console application that analyzes heat data files produced by Easy Tier and produces a graphical display of the amount of "hot" data per volume and predictions of how additional Solid State Drive (SSD) capacity could benefit performance for the system and by storage pool. This version of the Storage Tier Advisor Tool supports heat data files produced by Easy Tier on SAN Volume Controller 6.1, Storwize V7000 and DS8000 5.1, 5.1.5.
Heat data files are produced approximately once a day when Easy Tier is active on one or more storage pools and summarize the activity per volume since the prior heat data file was produced. On SAN Volume Controller and Storwize V7000 the heat data file is in /dumps on the configuration node and is named "dpa_heat.node_name.time_stamp.data". Any existing heat data file is erased whenever a new heat data file is produced. The file must be off-loaded by the user and Storage Tier Advisor Tool invoked from a Windows command prompt console with the file specified as a parameter. The user can also specify the output directory. The Storage Tier Advisor Tool creates a set of html files and the user can then open the resulting "index.html" in a browser to view the results.
Usage information can be found in a readme supplied with the Tool.
