Linux - Open Source Operating System

At the heart of all software is source code - the programs that perform basic functions. With open source software, this code is protected by a special license that ensures everyone has access to that code. That means no one company can fully own it. Freedom means choice. Choice means power.

That's why we believe open source is inevitable. It returns control to the customer. You can see the code, change it, and learn from it. Bugs are quickly found and quickly fixed. And when customers don't like how one vendor is serving them, they can choose another without overhauling their infrastructure. No more technology lock-in. No more monopolies.

We believe the open source model builds higher quality, more secure, more easily integrated software. And it does it at a vastly accelerated pace - often at a lower cost.

Open source spans platforms, middleware and applications. From data center to desktop. We help enterprises take full advantage of the capability and cost savings of open source-letting them do more with the technology they already have.

The subscription model allows Red Hat to have a mutually beneficial, cyclical relationship with customers:
Deliver new technology as soon as it's available.

Provide unlimited support at no additional cost.
And finally, the feedback we get from regularly working with you helps us deliver better technology tomorrow.

The benefits of choosing Red Hat
Red Hat is a leading contributor to the development of open source software. In fact, as noted by a couple of recent surveys, Red Hat is the leading corporate contributor to the most important open source project of all, the Linux kernel. Because Red Hat is the largest corporate contributor to the kernel, and able to influence features and strategy, this is an area where Red Hat is well-positioned.

A huge ecosystem of hardware and software partners offers both services and certified solutions, in collaboration with the industry leader. This powerful combination provides:

Thousands of certified applications from Independent Software Vendors (ISVs)

How to configure ISCSI target in Redhat 7

@ Motive behind iscsi protocol is to send hard disk (block device) over the network

@ In redhat 7  we are going to setup a cli target

Step 1 :  To setup target you need to install software which is in version 7 (targetcli)

[root@redhat7 Desktop]# yum install targetcli

step 2 : There is no need to start the service or open configuration file so use targetcli command

====

[root@redhat7 Desktop]# targetcli

targetcli shell version 2.1.fb34

Copyright 2011-2013 by Datera, Inc and others.

For help on commands, type ‘help’.

/>                                                            # this is the prompt of targetcli

i)  To list the architecture of iscsi target

/> ls

o- / …………………………………………………………… […]

  o- backstores …………………………………………………. […]

  | o- block ………………………………………. [Storage Objects: 0]

  | o- fileio ……………………………………… [Storage Objects: 0]

  | o- pscsi ………………………………………. [Storage Objects: 0]

  | o- ramdisk …………………………………….. [Storage Objects: 0]

  o- iscsi ……………………………………………….. [Targets: 0]

  o- loopback …………………………………………….. [Targets: 0]

/>

ii) To create a iscsi target block

/> cd  /backstores/block

/backstores/block>

/backstores/block> create  newhd  /dev/sda7

Created block storage object newhd using /dev/sda7.

/backstores/block>

iii)  To  create an  IQN number use below stpes

/backstores/block> cd /iscsi

/iscsi>

/iscsi> create                                                               # create command will automatically IQN number

Created target iqn.2003-01.org.linux-iscsi.redhat7.x8664:sn.66955d1bd65c.

Created TPG 1.

/iscsi>

OR you can give your own IQN number in proper format

/iscsi> create  iqn.2014-10.com.example:iscsit

Created target iqn.2014-10.com.example:iscsit.

Created TPG 1.

/iscsi>
