清华同方徐学雷博士: 用户选择光盘镜像服务器时主要应从容量、速度和价格三方面考虑。光盘镜像服务器的容量主要取决于内置的硬盘数量和大小。有些厂家的光盘镜像服务器在厂岀时已经预置了一定容量的硬盘,如果用户需要扩容,可将光盘镜像服务器上的可插拔硬盘盒抽岀,自行安裝硬盘进行扩容。 Tsinghua Tongfang Dr. Xu Xuelei: When users choose the CD-ROM server, mainly from the capacity, speed and price considerations. The capacity of a CD-ROM mirror server mainly depends on the number and size of the built-in hard disks. Some manufacturers’ CD-ROM servers have been preset with a certain amount of hard disks at the factory. If you need to expand the capacity, you can insert the removable hard disk box on the CD-ROM image server and install the hard disk to expand the capacity.
