from speaking directly with the VP and GM of the LSI Accelerated Solutions Division (ASD) during AIS 2011 interview, it is on the roadmap, and with existing controllers. There is no official timeline. The key is the correct implementation. As testing here has shown, there are TRIM lags/hangs and other issues that can arise from TRIM. A big thing also is predictability of performance, and in massive usage flash environments, with tons of devices, the extra I/O traffic. latency concerns..etc.
and you dont want to schedule it to happen at certain times...that can lead to unpredictable performance. OR even worse, hangs and lags like the type weve seen demonstrated here.
In the data center predictability is the #1 concern. No deviation in performance is the goal. The introduction of TRIM brings in alot more problems than one might think jsut looking at the surface. Different write loads could lead to different levels of I/O overhead...etc...3
most would actually prefer NO TRIM with flat line (lower) performance, than a performance gain that results in any type of deviation from SOP.
