Slide 2

ATA and SCSI AT Attachment (ATA) is a standard interface for associating stockpiling gadgets, for example, hard plates and CD-ROM drives inside PCs . SCSI ( Small Computer System Interface ) is an arrangement of measures for physically associating and exchanging information amongst PCs and fringe gadgets . Sets of charges to convey amongst PC and hard drives/fringe gadgets.

NAS and SAN NAS (Network Attached Storage) File I/O NFS, CIFS User Storage Client OS Server OS Client File System Server File System NFS Client NFS Server TCP/IP TCP/IP

Slide 4

NAS and SAN (Storage Area Network) Block I/O iSCSI, HyperSCSI, AoE, FC conventions Less overhead then File I/O User Client OS Storage Client File System Server OS Block I/O driver Block I/O Target driver Network

Slide 5

Data Sharing on Mobile Devices File I/O : NFS, FTP, CIFS, HTTP… .(Traditional ways) Block I/O: AoE, HyperSCSI, iSCSI Block I/O have higher execution then File I/O iSCSI can accomplish 10 times speedier then NFS Using system stockpiling as neighborhood drive This anticipate is about AoE and HyperSCSI on cell phones.

Slide 6

AoE(ATA over Ethernet) and HyperSCSI ATA and SCSI orders are embodied in Ethernet outline and transmit over Ethernet. Not at all like iSCSI, these 2 conventions does not lay above TCP/IP layer, in this manner it have better execution then iSCSI. It utilizes MAC addresses. It is not routable.
