Hello Ritu,  From the 2.0.1 Release Notes: The XtremCache feature is now called Read Flash Cache (Rfcache) - so, using SSD drives for read caching.  (As I think you know, Rmcache is SDS Server RAM cache - again read only caching.)
Hi there,  URL: https:// /api/types/StoragePool/instances   Info: "rmcacheWriteHandlingMode": "Cached","sparePercentage": 35,"checksumEnabled": false,"useRfcache": false,"rebuildEnabled": true,"rebalanceEnabled": true,"numOfParallelRebuildRebalanceJobsPerDevice": 2,"capacityAlertHighThreshold": 80,"capacityAlertCriticalThreshold": 90,"rebalanceIoPriorityAppIopsPerDeviceThreshold": null,"rebuildIoPriorityAppBwPerDeviceThresholdInKbps": null,"rebalanceIoPriorityAppBwPerDeviceThresholdInKbps": null,"rebuildIoPriorityQuietPeriodInMsec": null,"rebalanceIoPriorityQuietPeriodInMsec": null,"zeroPaddingEnabled": false,"backgroundScannerMode": "Disabled","rebuildIoPriorityBwLimitPerDeviceInKbps": 10240,"useRmcache": false,"rebalanceIoPriorityBwLimitPerDeviceInKbps": 10240,"rebuildIoPriorityPolicy": "limitNumOfConcurrentIos","rebalanceIoPriorityPolicy": "favorAppIos","rebuildIoPriorityNumOfConcurrentIosPerDevice": 1,"rebalanceIoPriorityNumOfConcurrentIosPerDevice": 1,"rebuildIoPriorityAppIopsPerDeviceThreshold": null,"backgroundScannerBWLimitKBps": 0,"protectionDomainId": "29efc5b456464000","name": "STOR","id": "345364356457474",  Question: Is "useRmcache": false  same as RAM read cache status? And also what is "useRfcache": false  Thank you, RItu
Where can I find RAM read cache in Storage pool rest
