Tips about incorporating flash into storage arrays

From Wikibon

EMC’s DMX customers should identify the applications that can benefit from flash-based SSD and begin testing the capability. However, users should be aware that questions remain regarding the durability and importantly the serviceability of these devices. Despite being 30X the price of conventional storage, users should evaluate tier-0 not necessarily based on cost/MB, but cost per I/O. Non-DMX customers should wait to understand competitive responses, which should be forthcoming. In and of itself, the inclusion of SSD is not a reason to incur subsystem switching costs.
