Hello, I need a 'server' to run a single MYSQL and PHP enabled web site. The maximum number of concurrent users for this site is about 250. Here in Japan the financial year is coming to an end so I have to make a decision by the end of March. For the last five years I have been using a MacPro (2006/7 3.0 GHz Dual-core Intel Xeon, 6GB memory, Four 1TB hard drives) with the standard client OS X software (i.e. not the server software) to run the MYSQL and PHP enabled web site. This MacPro has been running fine as a 'server', however I feel it's time to get a new machine before things start going wrong. So, I have until the end of March to buy: 1) 2010 MacPro Server: 2.8GHz Quad-Core Intel Xeon "Nehalem" processor, 8GB memory, Four 1TB hard drives, with a Mac Pro RAID Card OR 2) 2011 MacMini Server: 2.0GHz Quad-Core Intel Core i7, 8GB memory, Two 256GB Solid State Drives, with a Promise Pegasus R4 4TB (4x1TB) RAID System My budget will cover the more expensive but older MacPro, but the MacMini option will save me about $600. Assuming that the elusive '2012 MacPro' is not released before April 1st, which would you choose, the 2010 MacPro server or the 2011 MacMini server, and why? Or, given my requirements (a server for a single MYSQL and PHP enabled web site with a max of 250 concurrent users), which machine and specifications would you suggest? For example, since I don't really need the server software, perhaps a MacPro with a faster CPU and the client OS would be better? Any suggestions will be most welcome.
