Network Types
Most storage networks use the SCSI protocol for communication between servers and disk drive devices. A mapping layer to other protocols is used to form a network:
- ATA over Ethernet (AoE), mapping of ATA over Ethernet
- Fibre Channel Protocol (FCP), the most prominent one, is a mapping of SCSI over Fibre Channel
- Fibre Channel over Ethernet (FCoE)
- ESCON over Fibre Channel (FICON), used by mainframe computers
- HyperSCSI, mapping of SCSI over Ethernet
- iFCP or SANoIP mapping of FCP over IP
- iSCSI, mapping of SCSI over TCP/IP
- iSCSI Extensions for RDMA (iSER), mapping of iSCSI over InfiniBand
Storage networks may also be built using SAS and SATA technologies. SAS evolved from SCSI direct-attached storage. SATA evolved from IDE direct-attached storage. SAS and SATA devices can be networked using SAS Expanders.

Famous quotes containing the words network and/or types:
“Of what use, however, is a general certainty that an insect will not walk with his head hindmost, when what you need to know is the play of inward stimulus that sends him hither and thither in a network of possible paths?”
—George Eliot [Mary Ann (or Marian)
“As for types like my own, obscurely motivated by the conviction that our existence was worthless if we didn’t make a turning point of it, we were assigned to the humanities, to poetry, philosophy, painting—the nursery games of humankind, which had to be left behind when the age of science began. The humanities would be called upon to choose a wallpaper for the crypt, as the end drew near.”
—Saul Bellow (b. 1915)
