What is the biggest advantage of hyper-converged infrastructure compared with traditional IT infrastructure?

Compared with the traditional FC SAN architecture, hyper-converged architecture has the following significant changes:

Instead of using proprietary storage hardware and network, we use standard and easy-to-maintain x86 servers and 10gb Ethernet switches.

The core is distributed storage, and each server is a storage controller. It should be noted that each node needs to configure SSD disk as cache, and the cache capacity is much larger than the volatile memory of traditional storage, and the concurrency of multiple nodes brings stronger aggregation performance;

Logically, storage is no longer a different storage space composed of RAID, but a unified and flexible storage pool with stronger expansibility.

Another benefit brought by distributed storage is that performance and capacity can be configured on demand in a unified resource pool, and data can be automatically balanced;

Compute virtualization and storage are deployed on the same server node.

Through the comparison of the above architectures, we can see that the transformation of hyper-converged architecture is firstly the replacement of traditional storage by distributed storage, which brings other advantages (such as building based on x86 server, concurrency, easy expansion, etc.).

Of course, the unique deployment mode of distributed storage and virtualization further simplifies users' IT architecture, reduces the use cost and the difficulty of operation and maintenance, and these values also greatly accelerate users' acceptance of distributed storage mode.
