Storage virtualization

What is storage virtualization?
Storage virtualization groups the physical storage of multiple network storage devices so that it looks like a single storage device.

Der Prozess umfasst das Abstrahieren und Abdecken der internen Funktionen eines Speichergeräts von der Host-Anwendung, Host-Servern oder einem allgemeinen Netzwerk, um die anwendungs- und netzwerkunabhängige Speicherverwaltung zu ermöglichen. Storage-Virtualisierung wird auch als Cloud storage designated.
Managing storage and data becomes difficult and time consuming. Storage virtualization helps solve this problem by enabling simple backup, archive and restore tasks in less time. Storage virtualization aggregates the functions and hides the actual complexity of the storage area network (SAN).

Storage virtualization can be implemented using software applications or appliances. There are three major reasons for implementing storage virtualization:

1. Improved storage management in a heterogeneous IT environment
2. Better availability and estimation of downtimes through automated management
3. Better memory usage
Storage virtualization can be applied to any level of a SAN. The virtualization techniques can also be applied to various storage functions such as physical storage, RAID groups, LUNs (Logical Unit Numbers), LUN divisions, storage zones and logical volumes, etc.

The storage virtualization model can be broken down into four main layers:

1. Storage devices
2. Block the aggregation layer
3. File / recording layer
4. Application layer

The benefits of storage virtualization include automatic management, expansion of storage capacity, reduction in manual monitoring time, easy updates, and reduced downtime.
