<me> I've specced up the replacement server and got a good quote from our web hosting company.

<boss> ok

* after a week *

<boss> I've ordered the server and we got a free upgrade! They're giving us 2 x 2 Tb disks instead.

<me> Err, you realise the original spec had 6 146GB 15k SAS disks, right? That's not an upgrade. We're only replacing things because the old system doesn't have enough IO to keep up with the workload.

<boss> It'll be fine.

* day after replacement server goes in, things start to fall over. 'New' server actually has worse IO performance than the server it was replacing *

<boss> but you specced the machine!

* SIGH *
