CIFSnative with all Windows and MacOSXUN*X, Linux can do it with Samba package.worst performance of the bunch.

AFP (AFPoverTCP)native with MacOSXlinux can do it with Netatalk package.best performance of the bunch.

iSCSIblock storage (like internal/SAN storage)can have any filesystem.needs an iSCSI initiator.slower speeds that local storage.

21Wednesday, January 2, 13

AoEblock storage (like internal/SAN storage)can have any filesystem.although over the network, does not use TCP/IP.can not be routed.least amount of support of the NAS protocols.

22Wednesday, January 2, 13

FCoEblock storage (like internal/SAN storage)can have any filesystem.works with Lossless Ethernet.must be used with a CNA.not finalized standard yet.
