I have a little question for you guys, how you configure the swap datastore for for your environment ?
I have 3 ESXi 4.1 Server with 48 Gb RAM per ESXi and I have configured the swap datastore with 150 Gb.
I have read in the Best Practice Netapp VMware that's we can configure a option "Autogrow FlexVol volumes"
do you use this option?

Hi Vince and welcome to the Communities!
Autogrowing volumes is a part of a bigger picture of space management, so this is not necessarily specific to vShpere, swap files, etc.
The short answer is: your mileage may vary, as everyone has their own likes / dislikes re space management.
Volume autosize was mainly introduced to address the dilemma re volumes with LUNs & snapshots, where originally the best practice asked people to halve their usable capacity (simply speaking) to guarantee that LUNs will not go offline due to a lack of space in the volume.
There are different ways of achieving pretty much the same goal - e.g. my favourite of oversizing significantly all volumes, setting space guarantee to none (thin provisioning) & monitoring free space on the aggregate level only (not everyone likes this approach though).
