What are two minimum disk requirements for a vSAN hybrid disk group configuration?

In a vSAN hybrid disk group configuration, a fundamental requirement is the presence of at least one magnetic data disk to store data. Magnetic data disks are utilized in this setup to handle the bulk storage of virtual machine data, while flash devices are used for caching purposes. This hybrid approach allows for efficient data retrieval, with the flash device caching frequently accessed data and the magnetic data disk handling the less frequently accessed data.

In addition to a magnetic data disk, having at least one flash device is also crucial for a functional hybrid disk group. The flash device boosts performance by providing quick access to cached data, which is especially important for read and write operations. Without a flash device, the performance gains from caching would be lost, resulting in slower data access times.

Understanding the balance between these components is essential for configuring a vSAN hybrid disk group correctly, as both types of disk are necessary to achieve optimal performance and capacity in a vSAN environment.
