This month I’ve subscribed to CBTNuggets to get trained up on VMWare’s vSphere product.  Especially the networking components.  Along the way I’ve learned more interesting things – first of which is a open source iSCSI program that can provide remote storage.  It is called OpenFiler and can be run on bare metal or a VM.  A download can be had from here.  It looks pretty handy, and reminds me a bit of FreeNAS.
