s technology infrastructure grows, our capacities and performance must also grow in proportion to them. Assigning SAN storage capacity in the VSphere environment is commonplace, and the new storage capacity can be allocated within a few minutes to the new LNUs in the ESXi hosts. When you reach the software definition for software such as VMware VSAN, you will add an ESXi physical memory or host to the VSAN branch host to add the capacity of the VSAN DataStore. In this article, we will explain how to add disk capacity to VSAN Disk groups to increase the VSAN Data Store’s capacity.

VMware vSAN is the platform for defining the VMware memory software that provides the most secure and optimal storage space. Using VSAN on storage servers can provide a very flexible database for any virtual work.

Hard disks are very important for VSAN implementation. Increasing VSAN branches by increasing the hard disk or adding Disk Group to VSAN branches is not very difficult, and you can do this online; after doing this, the hard disk or hard disk group immediately to provide space. Reconstruction or balancing of operations is available.

How to add a disk's capacity to a disk group in the VSAN?

This step is only required if the VSAN disk request mode is set to manual mode. If the VSAN is set to auto mode, it will automatically display all of the empty memory locations in the ESXi hosts. If you intend to add multiple hard drives to the server, we recommend that you change the VSAN mode to Manual to make the hard disk drive to VSAN disk groups easier and better.

 

Prerequisites for adding hard disk space to VSAN Disk Group:

1. ESXi Physical Server must have free and free slots for connecting new hard drives.

2. The VSAN Claiming mode must be manual.

3. The new hard disk should be available in the same way as the attached hard drives; for example, a hard disk or magnetic disk. Hybrid VSAN for magnetic hard drives and All Flash VSAN for hard disk drives.

4. The new hard disk cannot have a partition, and if it has partitions of different formats, we can remove it from the VSphere Web Client.

At the bottom of the screenshot there are shot from the disk group and hard disks in the disk group. I have exactly 3 hard disk drives in each disk group; in each disk group, one of the hard disks is used as cache memory and 2 other hard drives are used for storage. The maximum hard disk that can be used as a cache in any Disk Group is a hard disk and we cannot use more than one hard disk for cache.

The maximum number of hard drives that each Disk Group accepts as storage cache is 7 hard drives, and each host supports up to 5 Disk Groups. This means we can connect to any host of 35 magnetic storage media as storage space.

You can scan and view the hard drives connected to the server slots in the ESXi hosts; to scan again, follow the path below:

Right the VSAN cluster -> Storage -> Rescan Storage

 

Scan for new storage devices and click OK.

 

The scan is over and now I can see new devices.

To add a new hard disk in Disk Group, follow the path below:

VSAN Cluster -> Configure -> VSAN -> Disk Management

 

  Select the Disk Group from the ESXi directory, go to the Disk Group you want to add the hard drive and click on the add-on icon.

Then click on one or more hard drives you want to add, and then click OK.. 

After adding the hard disk to the Disk Group, the hard disk or drives that are added to the Disk Group start working and can be used to provide memory, reconstruct or balance in operation.
