Server Suggestion Request

[operationsengineer1 at yahoo.com]

hi all,

thanks for the responses.  what about a core 2 duo for the 15-20 machines?

specifically, i'm thinking about this one...

http://configure.us.dell.com/dellstore/config.aspx?c=us&cs=04&kc=6W300&l=en&oc=bedw42h&s=bsd&fb=1

which is on sale from dell.  i could upgrade from the 1.86 GHz to the 2.13 GHz pretty painlessly if it made sense for my use.

i'm not familiar with raid and they offer a raid option.  is that worth it?  can an open source software solution work nearly as well?  i was thinking that of setting up a nightly back up to the 2nd hd, but i don't really have any experience doing that or setting up and working with raid.  i would think the former would be easier to implement.

i will definitely have a GB connection between the server and the switch.

tia...

oei

Usualy, you must allow 512 Mb for the server itself plus 512 Mb per
group of 7-10 clients.

So, to run 15 client you'll need about 1,5 Gb and a quad core is more
than good.

But you have to take care about a gigabit network card and a switch with
a gigabit port.

The disk speed and reliability is also important : two SATA disks
configured in RAID 1 could be fine.

François
