This speaks nothing of HyperSCSI which is indepenant of TCP/IP and all of it's ugly overhead. Hyperscsi runs in raw ethernet, no TCP/IP even need be on the wire. Data writing w/ HyperSCSI is far faster than with NFS or iSCSI. -- Jesse Keating RHCE MCSE Pogo Linux -- Support Tech tel: 888.828.7646 _______________________________________________ linux-lvm mailing list linux-lvm@sistina.com http://lists.sistina.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
