Hi Justin, re: questions > Both up and downstream servers should have plenty of bandwidth. Very good. re: what kind of machine are we talking about and what OS will it be running > That inherently is the problem. The machine we are using now is a 4 > processor Dell PowerEdge 6600 with 5GB of memory (32bit Xeon MP chips) > (Debian Linux 2.4 kernel). Because we feel safer with a 6-8GB queue, we > are trying to figure out what to do. We have found the Sun SunFire V20Z machines to be _stellar_ performers at a reasonable cost. The fully configured units we are using in our IDD cluster cost approx. $5500 fully loaded with 16 GB of RAM. > Since we appear to be limited to 4GB > queue for 32bit machines, we could, I suppose, buy some more memory and > run 2 LDM servers off the same machine but I kind of gathered that wasn't > a real great idea. It isn't a very good idea. > So we've been toying with the idea of getting a new > 64-bit machine soley to run our LDM server. In addition to the SunFire V20Zs, we have experience with Dell dual Xeon EM64Ts. If I had to choose which box to use for LDM/IDD activities, I would choose the V20Zs especially since they support up to 16 GB of RAM on the motherboard. > However, while it is > relatively easy (and cheapily) possible to get a 64bit machine, its more > difficult and more expensive to a get 64-bit machine which also supports > 16GB of memory (based on someone telling us we need 2x[queue size] for > memory) $5500 for a loaded V20Z (university discount) is not a bad deal. I recommend you check out what kind of deal you can get through your local Sun rep.
