LIO
1
LIO currently supports the
iSCSI, FCoE and InfiniBand
(SRP) protocols

LIO - Fabric modules
1
A fabric module provides the services of
the SCSI target module over a definite
protocol. There are fabric modules for
Fibre Channel, FCoE (Fibre Channel over
Ethernet) SCSI over IP networks, and
others. With this, one may build so-called
Storage Area Networks (SAN).

LIO - Features
1
The configuration of LIO is done through
Linux's configfs, the administration through
a command-line utility (RTSadmin).
Starting with version 2, configurations for
Fibre Channel, FCoE and Infiniband can
be so administered. Version 2 was dual
licensed and a community version
'targetcli' has been released under the
AGPL.

NetApp - Filers
NetApp's filers initially used NFS and
CIFS protocols based on standard local
area networks (LANs), whereas block
storage consolidation required storage
area networks (SANs) implemented with
the Fibre Channel (FC) protocol. In 2002,
in an attempt to increase market share,
NetApp added block storage access as
well. Today, NetApp systems support it
via FC protocol, the iSCSI protocol, and
the emerging Fibre Channel over
Ethernet (FCoE) protocol.

iSCSI - Concepts
1
As a result, iSCSI is often seen as a lowcost alternative to Fibre Channel, which
requires dedicated infrastructure except in
its FCoE (Fibre Channel over Ethernet)
form

Data center bridging
1
The higher level goal is to use a single set
of Ethernet physical devices or adapters
for computers to talk to a Storage Area
Network, Local Area network and
InfiniBand fabric.Silvano Gai, Data Center

FCoE
1
'Fibre Channel over Ethernet' ('FCoE') is a
computer network technology that
encapsulates Fibre Channel frames over
Ethernet networks. This allows Fibre
Channel to use 10 Gigabit Ethernet
networks (or higher speeds) while
preserving the Fibre Channel protocol.
The specification was part of the
International Committee for Information
Technology Standards T11 FC-BB-5
standard published in 2009.
https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html
FCoE - Functionality
1
FCoE protocol specification replaces the
Fibre Channel Protocol#Layers|FC0 and
FC1 layers of the Fibre Channel stack with
Ethernet. By retaining the native Fibre
Channel constructs, FCoE was meant to
integrate with existing Fibre Channel
networks and management software.
https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html
FCoE - Functionality
Data centers used Ethernet for TCP/IP
networks and Fibre Channel for storage area
networks (SANs). With FCoE, Fibre Channel
becomes another network protocol running
on Ethernet, alongside traditional Internet
Protocol (IP) traffic. FCoE operates directly
above Ethernet in the network protocol stack,
in contrast to iSCSI which runs on top of TCP
and IP. As a consequence, FCoE is not
routable at the IP layer, and will not work
across routed IP networks.

FCoE - Functionality
Since classical Ethernet had no
priority-based Ethernet flow
control|flow control, unlike Fibre
Channel, FCoE required
enhancements to the Ethernet
standard to support a priority-based
flow control mechanism (to reduce
frame loss from congestion). The
IEEE standards body added priorities
in the data center bridging Task

https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html
FCoE - Functionality
1
FCoE encapsulation can be done in
software with a conventional Ethernet
network interface card, however FCoE
CNAs offload (from the CPU) the low
level frame processing and SCSI
protocol functions traditionally
performed by Fibre Channel host bus
adapters.
https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html
FCoE - Application
1
The main application of FCoE is in data
center storage area networks (SANs).
FCoE has particular application in data
centers due to the cabling reduction it
makes possible, as well as in server
virtualization applications, which often
require many physical I/O connections per
server.
https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html
FCoE - Application
With FCoE, network (IP) and storage
(SAN) data traffic can be consolidated
using a single network. This consolidation
can:

FCoE - Frame Format
1
Reserved bits are present to guarantee
that the FCoE frame meets the minimum
length requirement of Ethernet
https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html
FCoE - Frame Format
1
The FIP (FCoE Initialization Protocol)
is an integral part of FCoE. Its main
goal is to discover and initialize FCoE
capable entities connected to an
Ethernet cloud. FIP uses a dedicated
Ethertype of 0x8914.

FCoE - Timeline
1
The FCoE technology was defined as
part of the International Committee for
Information Technology Standards
(INCITS) T11 FC-BB-5 standard that was
forwarded to ANSI for publication in
June 2009.
