Actually, its the workload's I/O type that has the most effect on the number of flash drives per bus.  Flash drive bus allocation is discussed in EMC CLARiiON Best Practices for Performance and Availability, FLARE 30.0in the 'RAID groups' sub-section of the 'Enterprise Flash Drive (Flash drive) storage' section.   In addition, there is a discussion of backend bus operation found in EMC CLARiiON Storage System Fundamentals, in the 'Drive and backend bus bandwidth' section that you may find interesting. (Hint: pay attention to the disk queues description, and then the 'buffering affect of cache'.)  Both of these documents are available on Powerlink.
