An xSeries specialist monitors a customer’s server that has poor performance. The customer is running an x365 with a ServeRAID 6i controller with write-back cache turned on and ten 15K rpm drives in a RAID-5 array. It is a mission-critical server and must have a redundant storage system. Performance tests indicate that the Average Disk sec/Transfer exceeds 20 ms. Which of the following is the lowest-cost method to increase the throughput？（） ["Disable the ServRAID cache","Change the RAID level to 10","Change the cache level to Write Through","Add five more drives to the array to increase the number of read\/write head"]

挪威人喜欢吃沙丁鱼，尤其是活鱼。市场上活沙丁鱼的价格要比死鱼高许多。所以渔民总是千方百计地想法让沙丁鱼活着回到渔港。可是虽然经过种种努力，绝大部分沙丁鱼还是在中途因窒息而死亡。但却有一条渔船总能让大部分沙丁鱼活着回到渔港。船长严格保守着秘密。直到船长去世，谜底才揭开。原来是船长在装满沙丁鱼的鱼槽里放进了一条以鱼为主要食物的鲶鱼。鲶鱼进入鱼槽后，由于环境陌生，便四处游动。沙丁鱼见了鲶鱼十分紧张，左冲右突，四处躲避，加速游动。这样一来，一条条沙丁鱼欢蹦乱跳地回到了渔港。原来鲶鱼进入鱼槽，使沙丁鱼感到威胁而紧张起来，加速游动，于是沙丁鱼便活着到了港口。
上面的案例说明的是一个非常著名的心理学效应，它是（） ["皮格马利翁效应","海潮效应","鲶鱼效应","沙丁鱼效应"]
