I'm not sure, but I believe that the Smart Array 532 doesn't have write cache and doesn't support it : http://h18004.www1.hp.com/products/servers/proliantstorage/arraycontrollers/smartarray532/questionsanswers.html#11 and in the specs : http://h18004.www1.hp.com/products/quickspecs/10851_div/10851_div.html " 32MB Memory optimizes performance and data throughput. NOTE: 32 MB of DRAM used for code, transfer buffers, and non-battery backed read cache " -- Philippe Pegon
