Hello, Jackson!

1. What is storage virtualization?

Storage virtualization abstracts storage devices as data stores and VMs are stored in data stores.

The store is stored as a set of files in its own directory.

For more details, see FusionCompute Storage Virtualization.

2. What are the characteristics of virtualized storage and non-virtualized storage?

Storage type: virtualized and non-virtualized (Local storage, FC storage, and iSCSI storage support virtualization and non-virtualization.) , distributed storage (Fusion Storage, or Server SAN), and NFS (NAS, with few applications)

Only virtualization and distributed storage support advanced features of storage virtualization.

Virtualized storage: The storage virtualization technology can format different storage devices, shield differences such as storage device capabilities and interface protocols, and convert various storage resources into data storage resources for unified management.

Non-virtualized storage: Based on logical volume management, it has higher performance, faster speed, and higher efficiency than virtualized storage. However, it has few functions and does not support snapshots and thin provisioning as much as storage virtualization.

Raw device mapping: A physical raw device is directly mapped to a VM. The VM disk can process SCSI commands. This feature applies to key business scenarios, such as database services.

Hope this helps!
