How iSCSI Works: The Technology Behind Internet Storage
iSCSI, or Internet Small Computer Systems Interface, leverages the power of IP networks to transmit SCSI commands. This enables data storage and retrieval over large distances without sacrificing performance.
At its core, iSCSI encapsulates these commands into TCP packets. This creates a seamless communication channel between servers and storage devices. The use of standard Ethernet infrastructure makes it both cost-effective and widely accessible.
The architecture consists of initiators and targets. Initiators are typically servers that send requests, while targets are the storage resources responding to those requests. Together, they create a robust framework for managing data efficiently.
Security protocols such as CHAP (Challenge Handshake Authentication Protocol) enhance safety during transmission. By ensuring only authorized users access sensitive information, iSCSI fosters trust in network-based environments.
This technology supports various applications from virtualization to backup solutions. Its flexibility allows businesses to adapt quickly in a rapidly changing digital landscape.
