Server questions

[Bob]

Thanks JP, that was a helpful answer :) I always forget that the datasets will be large in size. I`ve only ever worked with tiny datasets such as 211 grid domain, those were only around 2mb !!! 

It`s going to take me a while to get some kind of idea about using GrADS, so for now I`l install it and just play around.

Regards,
Bob.

  Hi Bob 
      As i mentioned in an earlier e-mail, grads itself won't be demanding on your server, however the datasets that you bring in can be large and over time start becoming an issue for storage, small datasets such as the wam output are around 37Megs and are produced every 6 hours, gfs is in the order of 250 Mb and ocean data sets can be of the order of 500Mb, obviously if you want to do intensive processes on these files your load will increase significantly for the duration of the processing. I have found that giving people usage of grads via perl scripts can lead to heavy usage and slow things down dramatically, I would recommend that you create your charts via scripts and save as png and let the users browse those.
       On a side note commercial packages that will do what you want such as idl or matlab are generally expensive, more tricky to use and speaking from usage of idl, less stable than grads, they do of course have great functionality that quite frankly is often useless with weather data. Another package that you may consider that is free is GMT, I've played with it and it has some great functionality (especially in the map projections) but again bit more tricky to use. Vis5D is another package, seems to have stunning graphics in 3D but I've never used it.

       Good Luck

    I`m still very new to GrADS and have barely touched the surface. I do however have big plans in the future, including producing some limited model products on my site. 

    My biggest question at the moment is, what kind of server environment should I be looking for to even consider running GrADS on a remote server. Hardware specs are my concern. These may seem like dumb questions to many, but this is a first time for me!! I have visions of spending weeks, maybe even months learning how to use the scripting etc. Only to find GrADS will be bogging my site down, and crashing it!! 

    Can someone shed some light on this subject. Hopefully you`ll see what I getting at!! 

    What I want: 
    Software that can run on my sites server, can import, ingest and contour model data into maps. 

    Regards. 
    Bob.
