Can I implement EFD on CX4-120 or CX4-240?   Yes.  However you should study your workload to determine the best way to deploy them.  You should note that the CX4-120 is a single bus system.  The CX4-240 is a dual bus system.  EMC CLARiiON Best Practices for Performance and Availability, FLARE Revision 30.0 contains specific recommendations on flash drive deployment and provisioning in its 'Enterprise Flash Drive Storage' section.  However, the biggest 'bang for the buck' with flash drives comes with using them as a secondary cache via the FAST Cache feature.  This uses the fewest flash drives to achieve the lowest overall response time.  Note your results will be workload dependent.  (You always need to understand the workload's characteristics, when trying to determine how a feature will perform.)  This is discussed in the 'FAST Cache' section of Best Practices.  Best Practices 30.0 is available on Powerlink.
Hi All,  Can EFD & FC disks mix at the same DAE? Or I need to prepare specific back end loop for flash drive?   Dennis
