Hi Ritu,  there is no FastCache supported on the Unity xxF all-flash systems. I doesnt make sense to use SSD based cache for SSDs Even in hybrid systems or VNX any data that already is on SSD wont be promoted into FastCache.  Both the hybrid and all-flash systems run the same Unity OE so the REST API docs are the same and are updated with a new Unity OE release if there are changes.  If you find errors / omissions in the REST API docs please open a service request and ask customer service to raise an documentation bug (AR) so that it gets updated.  regards Rainer
Hi there,  I am trying to access fastcache info from a Unity 450F model using restAPI - /api/types/fastCache/instances?fields=id,sizeTotal,sizeFree,numberOfDisks,health,raidLevel,raidGroups,raidGroups  This API works with previous versions of Unity but not with 450F model. Has this api changed? All other restAPIs works fine except for this one. Please help.  Also, looking for RESTapi document for Unity 450F.  Thank you!   Regards, Ritu
