hello list- i am beginning to spec out a box that will run a php/mysql application, that will have (initially not many) up to a couple thousand dumb devices phoning home ever hour to 4 hours. each phone home will check to see if it has a new file to download. most phone homes wont have any thing to download. however, when a download becomes avail, it will be downloaded buy a group of anywhere from 1, 2... 50 on up to maybe 1000 units will be downloading the 3-4 meg file spaned over the phone home interval (1 - 4 hrs) for that group of units. so, if there is a group with 200 units in it, and their phone home interval is 1 hr, the next time a new download is made avail, all 200 units will want to dl that update over the next hour, (plus all the other phone home status checks from all the units). is this not really that much bandwidth or IO? I guess if 200 units over 1 hr dl a 4 meg file, its 800 megs over an hour, thats not all *that* much. I need to plan hardware/bandwidth wise to make sure this process works smoothly. Should i be looking at a dedicate box to run this? Currently its going on our main server which has other things like qmail, apache, and jabber servers running on it. thanks for any advice/insight. duncan _______________________________________________ Twin Cities Linux Users Group Mailing List - Minneapolis/St. Paul, Minnesota http://www.mn-linux.org tclug-list at mn-linux.org https://mailman.real-time.com/mailman/listinfo/tclug-list
