CPU的(de)(de)主頻要(yao)(yao)高，要(yao)(yao)有較大的(de)(de)緩存靠性，不僅要(yao)(yao)滿(man)足運(yun)營(ying)系統(tong)(tong)(tong)(tong)(tong)的(de)(de)運(yun)行和業(ye)務處(chu)理的(de)(de)需要(yao)(yao)，而且(qie)能夠(gou)滿(man)足一定(ding)時(shi)期業(ye)務量(liang)的(de)(de)增長，尤其是在大型的(de)(de)、有大量(liang)處(chu)理要(yao)(yao)求的(de)(de)、需要(yao)(yao)長期運(yun)行的(de)(de)系統(tong)(tong)(tong)(tong)(tong)上。同(tong)時(shi)，服務器系統(tong)(tong)(tong)(tong)(tong)不僅要(yao)(yao)考慮服務器單個節點(dian)的(de)(de)可靠性或穩定(ding)性，而且(qie)要(yao)(yao)考慮服務器與(yu)相(xiang)關輔助(zhu)系統(tong)(tong)(tong)(tong)(tong)之間連接的(de)(de)整體可靠性，如：網絡(luo)系統(tong)(tong)(tong)(tong)(tong)、安全(quan)系統(tong)(tong)(tong)(tong)(tong)、遠程打印系統(tong)(tong)(tong)(tong)(tong)等。在必要(yao)(yao)時(shi)，還應考慮對關鍵服務器采(cai)用集群技(ji)術，如：集群。
