It’s going to be a little bit tough this time discussing something as obscure as this topic but I’ll certainly do my best to make it lighter and understandable as I can.

Web hosting as we all know operate on virtualized servers. Considering the concept of Storage virtualization involves the abstraction of logical storage from physical storage which means virtualization of storage takes place by making data independent of its location.

Having a little concept about web hosting, normally an IP is provided. An iSCSI (pronounced eye-skuzzy) also known as Internet Small Computer System Interface that is IP-based serves as the storage networking standard for linking data storage facilities. Whenever SCSI commands are carried over within the network, iSCSI facilitates the data transfers over intranets and manages location-independent data storage and retrieval over long distances using its existing network infrastructure. It also makes possible the transmission of data over local area networks (LANs), wide area networks (WANs), and the Internet.

As a popular storage area network (SAN) protocol, it provides organizations the ability to consolidate storage into data center storage arrays while at the same time providing hosts (such as database and web servers) with the illusion of locally-attached disks making it a lot better than the traditional Fibre Channel, which requires special-purpose cabling.

Having iSCSI storage software makes possible the conversion of any standard 64-bit or 32-bit Windows Server into a scalable SAN that can work over an existing Ethernet network. A great example of this is that of StarWind Enterprise Server that helps organizations build rock-solid, high-performance IP SAN on IT-friendly budget.

Part of iSCSI SANs disaster recovery mechanism is its ability to allow entire disk arrays migration across a WAN with minimal configuration changes, thus, making storage “routable” in the same manner as network traffic which can also be applied in extreme cases whenever there are prolonged outages. In simple terms, it can function as a back up.

I have only discussed the salient points of the topic and tried not to be too technical as much as possible. If you have any questions or insights that you would like to share, feel free to do so at the comments section. This post was brought to you by our friends from www.starwindsoftware.com.

    The great thing about iSCSI is that you can hack one together for under a $1,000 these days. Its won’t be the greatest solution but it will work if you have a tight budget.

    Hi Wolfgang,
    It’s good to have you here. I think iSCSI is economical and completely serves its purpose of making data management very efficient and secure.
