iSCSI is an acronym that stands for Internet Small Computer System Interface. Used by computer buffs, this term describes an Internet Protocol-based storage networking standard that is used to link information (data) storage facilities.

By transmitting SCSI commands through IP networks, iSCSI assists with data transmission over a range of platforms, including local area networks, wide area networks and the Internet. The people who use this type of interface are known as initiators, and they are able to send SCSI commands to SCSI storage targets (different devices) via remote servers.

iSCSI is a type of storage area network protocol which permits organizations to amalgamate storage into information center storage arrays, while also offering hosts (including databases and web servers) with the type of service that they would receive via locally attached disks. In contrast to old-fashioned Fibre Channel interfaces, which need custom cabling, iSCSI may be used over larger distances, through network infrastructure that is already in place.

Benefits of iSCSI

When you opt for iSCSI, you’ll access some important benefits. For example, this type of interface is quite cheap to put into place, and it is commonly believed to offer more benefits than DAS or NAS solutions. The reason why iSCSI is less expensive is because it will utilize an organization’s current Internet Protocol infrastructure, rather than requiring a brand-new infrastructure (which would inevitably boost the final tab for this networking standard).

In addition, there is significant simplicity to deploying this type of system. When you choose iSCSI, you’ll be likely to enjoy faster service, due to the system’s 10GbE characteristic. With regard to performance, iSCSI is able to deliver impressive results. Devices created especially for iSCSI devices cater to the SMB market, For example, managers often place large databases on iSCSI interfaces. However, this is not the only way to apply iSCSI technology.

IT managers appreciate the ease of iSCSI, because it works with a couple of popular networking standards, known as Ethernet and TCP/IP. Since lots of managers already understand one of both of these standards, they don’t need to develop new skills in order to implement FC storage with iSCSI.

As well, the costs of storing data tend to decrease when iSCSI is utilized. Since the price of installation and maintenance is also lower with iSCSI, managers may be able to avoid expensive outsourcing when they choose this type of interface. Replication will work via a standard IP network. This eliminates distance limitations and expenses related to more costly FC routers.

While some debate the perceived high performance is this type of interface, most agree that it offers a sensible and practical alternative to more expensive and complex fibre channel services. IT managers and others who are considering utilizing iSCSI must weigh the advantages and drawbacks of this networking standard before making a final decision about what is right for their specific needs and corporate budget.

iSCSI systems will function over long distances. Therefore, iSCSI resolves issues related to distance and bandwidth. The usage of IP Networking takes away problems relating to long distances and replication to remote sites.

iSCSI is a sensible solution for a range of applications and purposes. That’s why this networking standard is used in so many IT situations that require affordable data storage solutions and very good performance levels.

In a nutshell, iSCSI is one of the primary approaches to storing data transmission via IP networks. The other common method, Fibre Channel over IP, translates control codes and information into IP packages that are transmitted between disparate Fibre Channel SANs.

Now that you know more about iSCSI and how it is used to improve data transmission storage through IP networks, you’ll be ready to decide if this type of system has the capabilities and pricing that you need. Today, many managers find that iSCSI offers workable solutions, without the complexity and expense of Fibre Channel interfaces.

To find out more about iSCSI, take the time to visit message boards or other Internet resources where IT managers and other computer system specialists meet to discuss options and ideas. The Web provides a host of information about iSCSI and its pros and cons, so it’s possible to learn all about iSCSI, right from the comfort and privacy of your own home.
