¹ For CLARiiON arrays: The minimum FLARE OS version required to capture response times is 04.30.000.5.524 A11. Note that VNX (Block) will have completely different FLARE releases and all support the collection of the counter fields needed for capturing response time, starting with FLARE version 05.31.000.5.006 A01. Enable statistics logging on the VNX system.

² For Hitachi arrays: To collect performance data from Hitachi Tuning Manager, the Data Collector must be installed on the same server as Tuning Manager. And, a single Data Collector policy must be used to collect both the capacity data from the Device Manager server and the performance data from the Tuning Manager server.

³ For NetApp ONTAP (Block only): Total response time is the average latency (ms) for all LUN read and write operations. Performance data is collected for both iSCSI LUNs and FC LUNs.
