EMC Isilon creates millions of relationships among hard disks and file sharesDescriptionEMC Isilon is a storage cluster which distributes data across cluster nodes and hard disks to assure high availability and performance.EMC Isilon guaranties data will be available on demand and it implements single OneFS (file system) which makes data manipulationin the background transparent.Therefore, it's impossible or it doesn't make sense to connect the selected file share too many disks (hardware). However, EMC Isilonadmins could extract data locations but shared folders would be distributed all over the cluster. Steps to Reproduce 1. 'EMC Isilon' pattern ran and found 952 File Share and 1116 Disks 2. Step "80. relation to cmdb_ci_disk" creates relationships between above tables. 3. Looking at the condition for creating relationship, it looks like we just want to create rels from all Disks to every other File Shares => 952 * 1116 = 1,062,432 relationships. 4. Running this step caused MID Server to run into out-of-memory. After increasing MID Server heap and bumped up the value for 'com.glide.closure_max_rows_per_table' to 1,500,000 The pattern was able to finishWorkaroundDiscover and Service Mapping plugin updates are released monthly and every version is supported by every supported family release (Paris, Rome, San Diego at the moment).The fix has been targeted for the July 2022 release so probably you don't have to change anything if your version is greater than 1.0.90.If the pattern step still hasn't been disabled be free to disable to avoid creating millions of relationships in your production.1. Open EMC Isilon in Pattern Designer 2. Disable "80. relation to cmdb_ci_disk" step to stop creating disk to file share relationships 3. Save, publish and sync MIDs Related Problem: PRB1576704
