We have a VMAX 450F, All flash array to run our VMware Server Cluster(150) and Desktops(1,000).  Are there any optimization settings to take advantage of being all flash.  I would like to do Virtual Volumes, but the Cisco UCS servers do not support that feature.  Any recommendation of Volume Size?  We usually do around 1 TB for View Datastores and 2 TB for Server Clusters.  Is the VSI plugin for VCenter worth while installing?
