Intel=> Context memory is like processor cache memory. The LSISAS2008 doesn’t support “external” cache memory so it’s embedded in the ROC/Controller to provide a place for calculations and temporary data storage. Because it’s embedded there isn’t space for much memory (2MB).
Context Memory不作為任何cache使用, 它的存取由firmware來決定.
不同的firmware模式下提供的功能也不盡相同. IR/IT和IMR兩種模式決定不同的應用. LSISAS2008提供這兩種模式.
The design, firmware stack, driver family, and every aspect of these boards is completely different. They are in no way similar, with the exception that there are not hardware RAID.
IMR使用WebBIOS, 功能與特性遠比基礎的Fusion-MPT BIOS豐富許多, 設限也比較少. 不過在IR/IT模式下, LSISAS2008的Host Bus面向PCIe 2.0, 支持MSI-X, 提供大量的IRO資源操作, 對於CMP/SMP系統架構來說, I/O負載有正面上的助益.
