SAN vs NAS vs DAS
Direct Attached Storage – DAS
- DAS is a block device from a disk which is physically [directly] attached to the host machine.
- You must place a filesystem upon it before it can be used.
- Technologies to do this include IDE, SCSI, SATA, etc.
Storage Attached Network – SAN
- SAN is a block device which is delivered over the network.
- Like DAS you must still place a filesystem upon it before it can used.
- Technologies to do this include FibreChannel, iSCSI, FoE, etc.
Network Attached Storage – NAS
- NAS is a filesystem delivered over the network.
- It is ready to mount and use.
- Technologies to do this include NFS, CIFS, AFS, etc.
SAN vs. NAS
SAN traditionally employ low-level network protocols for transferring disk blocks, a NAS device typically works over TCP/IP and can be integrated fairly easily into home computer networks.
