HyperSCSI

OSI-modellen med kendte protokoller.
De anvendes bl.a. på datanettene:
Fastnet og trådløst: WAN (f.eks. internettet), MAN, LAN, PAN.
Kun trådløst: IPN, WMAN, WLAN, WPAN (f.eks. Bluetooth).

Lag	Lagnavn	IP bårne/relaterede (har RFC)
7	Program	HTTP, SMTP, POP3, IMAP, FTP, DNS, DHCP...
6	Præsentation	AFP...
5	Session	RPC, NetBIOS...
4	Transport	TCP, UDP, RTP...
3	Netværk	IP: (IPv4, IPv6), ICMP, IGMP, ARP...
2	Datalink	Ethernet, HDLC, V.42bis, V.42(LAPM), V.44...
1	Fysisk	V.34, V.90, ADSL, 802.11 Wi-Fi, WiMAX...

HyperSCSI er en effektivt designet dataprotokol, der kan overføre diskdata med op til 100 MByte/s (Byte!) over Gigabit ethernet datanet. I stedet for f.eks. UltraSCSI 320 kabler på max. 15m, kan diskene placeres flere km (fiber) eller 100 m (over TP-kabler) væk fra serverne.

To put this in "ordinary" terms, it can allow one to connect to and use SCSI and SCSI-based devices (like IDE, USB, Fibre Channel) over a network as if it was directly attached locally...."
