Hi there,
Thanks for the PM.
I've been working away on this in the mean time. Turns out that the Essentials license (the cheaper license) is only available for the ML350e Proliant Servers. The servers that we have installed are the ML350p servers, which require an Advanced license, and may just push it out of our price range.
I've downloaded the Advanced Trial license and installed it on one of our servers, just to get a good look at it, and it is VERY impressive what you can do with it. I've also got a quote from our local software provider. So we're now just trying to work out if it's worth the price. Like I said it is certainly impressive, but we have to see if it's worth the 250 euro that we're being quoted...
thanks to everyone.
Jonathan
