4.1. Linux as file and print server

4.1.1. Linux as file server

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 2 LVD SCSI at 80 MB/s, if the budget allows it, and 10.000 RPM disks.

Table 4-1. Sizing of a file server

Simultaneous users	RAM size	Disk size	Machine example
1 - 100	312 MB	27 GB	E800
100 - 500	1 GB	117 GB	LC2000
500 - 1000	2 GB	216 GB	LH3000

4.1.2. Linux as print server

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.

Table 4-2. Sizing of a print server

Simultaneous users	RAM size	Disk size	Machine example
1 - 100	312 MB	9 GB	E800
100 - 500	1 GB	9 GB	E800
500 - 1000	2 GB	9 GB	LC2000
