Configuring FAST VP FAST VP is either enabled or disabled Data Movement should be set to automatic Relocation Rate controls aggressiveness of FAST New Feature Allocate- by-Policy simplifies capacity management of thin Provisioned environments Time windows Create time windows to specify when data can be collected for performance analysis and when data movements can be executed. Recommend to have windows always open so FAST VP can use most recent analysis to optimize data placement.

Enable FAST VP Coordination on Storage Groups With this feature enabled, FAST VP sends device usage statistics from R1 to R2 to ensure that the FAST engine at the standby/failover site has up-to-date metrics on which to base decisions. Enabled under storage group management in Unisphere: –Check Box: Enable FAST VP RDF Coordination Coordination should be enabled on storage groups at both source and target VMAX

31© Copyright 2012 EMC Corporation. All rights reserved. Summary and Solution Benefits VMAX 40K provides an ideal platform for virtualized critical database applications, running varied workloads. Cascaded storage groups enable simplified management of ESX environments with FAST VP. FAST VP is tunable and responsive. By adjusting FAST policies, performance can be tuned to meet changing business performance needs. Increased performance within 30 minutes with no negative impact to other running workloads. End-to-end visibility with VMware Storage Integrator from EMC enables simplified management and identification of VMAX devices direct from vCenter SRDF coordination with FAST VP ensures production level performance at the R2 site in FAST VP environment in the event of a failover when configurations are similar. This delivers the performance and cost benefits of FAST VP at both production and disaster recovery sites.
