The sharing service uses 2 MB of RAM, and 2 more MB per share. In case of a unique share (users space for example), it leads to a 2 MB consumption per user. In the proposed case, we estimate that each user has 100 MB of disk space on the server, with an evolution to 200 MB 3 years later. Processor resources used are relativeley small, an entry level model will be sufficient from that point of view. We will priviledge the I/O speed with Ultra 3 LVD SCSI at 160 MB/s, if the budget allows it, and 15.000 RPM disks.
The sharing service uses 2 MB of RAM, and 2 more MB per printer shared. In case of a unique share (One printer per user typically), it leads to a 2 MB consumption per user. In the proposed case, we estimate that each user prints simultaneously files of 5 MB in average, thus we need to have that space available on the server. Processor resources used are relativeley small, an entry level model will be sufficient from that point of view.
