The computer interface, Internet Small Computer System Interface popularly known as iSCSI, is an internet based storage protocol for linking different computers within a single network.
The main two objectives of iSCSI are:
Comprehensive Storage consolidation
Data center organizations usually move different storage facilities from servers on the network into the central location, more often in data centers; this would allow more efficiency output in the allotment of storage space. In this type of storage environment, a main server can be allocated a new disk volume without changing any into the main hardware.
Disaster recovery options
Data management relay storage devices from a data center to another near data center that serves as a backup in the event of a power outage. iSCSI – storage area network allows entire disk arrays to be transferred with a WAN or WLAN with minimum configuration alterations, it is comparable in routing data in a similar manner as internet traffic.
iSCSI can be used to transmit information over the following facilities:
- Local area networks (LANs)
- Wide area networks (WANs)
- Internet via Cloud
One advantage seen on the use of ISCSI storage is it does not require special purpose cabling compared to traditional Fibre connection. iSCSI is a network communications protocol that allows users to install several hard drive storages in a single NAS (Network Attachment Storage) or in a storage location somewhere else. Although they would appear as a computer storage built into one box.
An iscsi storage device has the luxury of options that would allow users to connect different storage devices across the globe through the utilization of an active internet connection. For users interested in making backups of their storage data, they can also possibly set-up one in every different place.
iSCSI is compatible with i5/OS, VMware ESX, AIX, Windows, NetWare, HP-UX, Solaris, Linux, OpenBSD, NetBSD, FreeBSD, OpenVMS, and Mac OS X. For more information about iSCSI, kindly check it out at the given link.
