SL 4.5 and Lustre

Hi,

We are looking for a fast cluster file system and storage system for our SL 4.5 HPC cluster.
What are the experiences with Lustre 1.6.x and SL 4.5 ?
What modifications are necessary to get Lustre from clusterfs running on SL 4.5?
What cluster storage systems other than Lustre to you prefer?

Thanks

Peter
