When provisioning a NAS, the first step is to create one or more volumes with the disks installed in it.
NAS QNAP offers two types of volumes:
- Volume based on a pool of disks.
- Volume on raid disk group (static).
Both types of volumes each have their advantage and disadvantage.
Pooled volumes allow the use of snapshot, creating multiple volumes in a pool.
Volumes says static offers better performance.
Once pool or static volume created, it is not possible to go back without losing data.
Volume on a disk pool
It is possible to configure a spare disk at this stage of pool creation.
The disk pool is created, you must now add the volumes on it that will store the data.
It is possible to create a volume during pool synchronization.
Creating the volume
Static volume in RAID
In order to create a static volume, it is necessary to have free disks (not pooled and not allocated to a static volume).
Close the information messages that opens during the operation.
The choice of volume type is something important because it is difficult after changing it. Before you create a volume, you must define what it will serve.
Here are 2 examples of uses that I recommend:
- Virtual Machine Backup Storage: Static Volume
- File sharing or robocopy type backup: Pool + heavy volume to take advantage of snapshots.
When it comes to virtual machine storage for Hyper-V or VMware, I prefer to use SAN solutions that I think are more reliable and efficient.
