Which Storage Systems Are Best for Virtualization?
Virtualization has become an integral part of modern information technology. This technology allows you to create virtual instances of hardware, operating systems, and other resources, which greatly simplifies server management and increases their efficiency. However, for successful virtualization implementation, it is also necessary to choose the right data storage system.
Storage systems for virtualization must meet the requirements for performance, reliability, scalability, and manageability. Let’s consider several popular storage systems that are most often used in virtual environments.
1. Storage Area Network (SAN)
Storage Area Network (SAN) is one of the most common types of storage for virtualization. SAN is a high-speed network that connects servers and data storage, allowing servers to access data stored on remote devices. SAN provides high performance, fault tolerance, and scalability, making it an ideal choice for virtual environments.
2. Network Storage with iSCSI Protocol
iSCSI (Internet Small Computer System Interface) is a method of transmitting block data over a TCP/IP network. Storage systems with the iSCSI protocol allow you to use ordinary IP networks to transmit data between servers and storage. This method saves on equipment and simplifies the configuration of the data storage network for virtual environments.
3. Local Storage
Local storage is a drive that is physically connected to the server. This type of storage provides high performance because data is transferred directly between the server and the drive without using network protocols. However, local storage carries the risk of data loss in the event of a server failure, so data redundancy on other servers or storage devices is often used to ensure fault tolerance.
The choice of a storage system for virtualization depends on the specific requirements of the organization, such as budget, performance, level of fault tolerance, and scalability. It is important to pay attention to storage planning and management to ensure the effective operation of virtual environments.
So, the right choice of storage system will allow you to create a reliable and efficient virtual environment that will meet the needs of your business.
