<div dir="ltr"><div style="text-align: left;">we use similar specs for long time (2 years) for about 48 machines that are not active all the time. and it was enough :-) Core Duo 1.8GHz + 2 GB RAM + 160 GB HD + 1 Gig NIC + 100/10 Mb NIC recently we moved (upgraded the cpu and ram) to quad 1.8GHz with 4 GB RAM to support 70 terminals. they all run flash 9 on FF 2 + Openoffice + games + some other applications... smoothly :-) i will put up some of the sar files we gather for the last year or so from several servers we have so you can all explore them :-) (soon) </div> :-) <div>2008/6/6, Rob Owens <<a href="mailto:rob.owens@biochemfluidics.com">rob.owens@biochemfluidics.com</a>>:<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); border-right: 1px solid rgb(204, 204, 204); margin: 0pt 0.8ex; padding-left: 1ex; padding-right: 1ex;"> Personally I would want to have 2 SATA drives in software RAID 1. But if downtime isn't a big deal then a single drive would be ok. If the system is just being used for games, then maybe downtime doesn't matter. But do you think that people will start to use it for more than just games, and come to depend on this system? -Rob<div> Jamie Lists wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> We're thinking of putting 2 K12ltsp servers in each of our schools. Our home directories are located on other fileservers and mounted via NFS to the LTSP server. The LTSP server will not be doing dhcp / bind / etc etc. Most of our schools have the 2 post telco racks. So we we're thinking of buying the half length SuperMicro cases. <a href="http://www.supermicro.com/products/chassis/1U/502/SC502-200.cfm" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">http://www.supermicro.com/products/chassis/1U/502/SC502-200.cfm</a> With a SuperMicro motherboard/ 4 gig of ram / a single SATA 7200 RPM hard drive and one Intel Core 2 Duo E6850 Conroe 3.0GHz LGA processor. We're planning on trunking the 1gig nics together as well for a 2 gig connection to the switch. Clients will be assigned a server via DCHP. The DHCP table will have the MAC address of the client and the first choice of server to boot off of then the second and so on and so fourth. Mostly these will run clients at K-5 using flash based games like at <a href="http://funbrain.com" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">funbrain.com</a>. So my question is do you think 50 clients per server is a reasonable expectation? I guess my main concern is the hard drive being a SATA drive (not the no redundancy part it just not being a SCSI striped RAID setup ) Even though it's not hosting the home directories will it be good enough for launching apps?
