I am using this API for Virtual Storport under 2008. I have never seen this API working for this flag 0x13, which is to enable the STOR_PERF_DPC_REDIRECTION, STOR_PERF_INTERRUPT_MESSAGE_RANGES, and STOR_PERF_CONCURRENT_CHANNELS, and set the concurrent channels to some positive number. If anyone has any update about it working please update me. I have tried versioning mentioned in other threads to 3, but doesn’t work. May be need to open a case with Microsoft about it.
