Do i ask for multiple LUNs pretending that there is a C:\ (OS), E:\ (temp), F:\ (Data) and G:\ (log) disk structure or do I just present a very big space as a single C:\ drive and let it go.
Its depends on a lot of factors...
What type of SAN is it? If your SAN does virtualized peer storage (Bing EqualLogic) then a single C:\ will be fine and will save you a ton of research and decisioning. If you are using a SAN where you're managing physical spindles (i.e. spindles are not virtualized in the SAN) and you are forced to worry about spindle-isolation then you should seriously consider having separate volumes with dedicated spindles behind them for OS, tempdb, data and logs with appropriate RAID levels for each.
