Difference: 1. Each node of hyper-convergence is equipped with CVM, and its function is to replace the disk controller of the disk array; while there is no CVM on each node of virtualization, and the disk array is used. Disk controllers perform computation and storage. 2. Hyper-convergence has more elastic horizontal expansion capabilities, and virtualization has more elastic vertical expansion capabilities.
The difference between hyper-convergence and virtualization is: different composition, different nodes, and different scalability.
1. Different compositions
1. Hyper-convergence: Hyper-convergence forms a unified storage pool from dispersed storage resources, and then provides it to the hypervisor for creating application virtual machines.
2. Virtualization: Virtualization is a converged system that combines virtual machines and multiple node distributed storage resource pools.
2. Different nodes
1. Hyper-convergence: Each node of hyper-convergence is equipped with CVM, and its function is to replace the disk controller of the disk array.
2. Virtualization: There is no CVM on each virtualized node, and the disk controller of the disk array is used for calculation and storage.
3. Different expansion capabilities
1. Hyper-convergence: Hyper-convergence has more elastic horizontal expansion capabilities and can bring optimal efficiency, flexibility, scale, cost and efficiency to the data center. Data Protection.
2. Virtualization: Virtualization has more flexible vertical expansion capabilities and uses an integrated computing and storage platform to make the entire system clearer and simpler, greatly simplifying the design of complex IT systems.
