iSCSI and Virtualization Technology

Recently, virtual storage design improvements have begun to take advantage of iSCSI. IT professionals often interpret storage virtualization as a technology that enables distributed storage
systems to run as a single storage resource.

According to recent server virtualization advantages, the concept of storage virtualization is further interpreted as a way to create an abstraction layer between storage devices and logical data streams.

Storage virtualization is similar to server virtualization, and with this technology you can create an intelligent SAN infrastructure that is easy to manage and scale. Some storage virtualization designs take advantage of iSCSI features such as IP Redirect to simplify management and increase scalability.

Virtual storage distributes data streams across multiple different physical memories, including: disk arrays, RAID groups, different types of drives, and controllers.

This not only improves performance and testability, but also enables data flow from a storage device without interrupting the operation of the system and without affecting the application data application. Transfer to another.

A valid virtual server configuration depends on the sharing of the memory access path. The SAN ensures that each virtual server collaborates in a timely manner, quickly accessing the data set of any virtual machine, and realizing instant re-hosting of the virtual machine.

This eliminates the time it takes to copy virtual machine files, applications, and data from one virtual server to another.

In addition to the need for networked storage, virtual environments have increased the need for memory performance and availability to meet high load demands.

More critical applications, product workloads, and data resources are consolidated into less memory, so performance, non-disruptive scalability, and continuous availability of storage resources are even more High requirements.

In certain cases, storage structures should include mirrored memory write buffers, redundant hot-swappable devices, online hot spares, environmental monitors, and enterprise-class disk drives with RAID protection.

Second, advanced usability features, including memory controllers and I/O fault path switching, are used to ensure that data is still accessible in the event of a device failure.
