English to Chinese Tech/Engineering IT (Information Technology) virtualization

When dealing with physical servers, each server represents its own point of failure. So if we have ten servers, we have ten times the likelihood of outage than if we had only one of those same servers. Each server that we add brings with it its own risk.
面对物理服务器时，每台服务器各自就是一个故障点。所以，如果我们有十台服务器，那么出现停运的可能性是如果我们只有一台这样的服务器时的十倍。我们添加的每一台服务器都会带来各自的风险。
If each failure has an outage factor of 2.5 – that is, financially impacting the business for twenty five percent of revenue for, say, one day then our total average impact over a decade is the equivalent of ***two and a half total site outages***.
如果每次故障的停运系数是2.5——也就是说，给公司带来的经济损失占某段时间（比如一天）收入的25%，那么十年下来总的平均影响相当于2.5次***全站停运***。

还是说十年间站点停运的次数总共才2.5次？
