[Lustre-discuss] Adding iSCSI SAN to Lustre

Any block device, be it disk, RAID, IB SRP or iSCSI requires an OSS node 
to front end the block storage. If the iSCSI storage device was a 
storage server with a software iSCSI layer you could potentially strip 
out the iSCSI software and lay down Linux and Lustre on it. Without 
knowing exactly what iSCSI system it is my statement about stripping out 
the software is a generalization.
