Virtual Machine Disk Size
In today's fast-paced world, the ITS Private Cloud demands more agility and flexibility from its infrastructure. One of the key features of VMware vSphere is the ability to perform Storage vMotions, these allow you to move virtual machine disk files (VMDKs) from one storage location to another without incurring downtime. This capability can greatly enhance the overall management and maintenance of the ITS Private Cloud virtual infrastructure and help our team respond quickly to changing requirements.

Virtual Machine Storage Type
The ITS Private Cloud offers two high-availability storage cluster types per domain, providing users with flexibility and control over their virtual machine storage needs.
Available Storage Options
HDD Enterprise SAS Storage
SSD Enterprise SAS Storage
Each domain (FD1, FD2, FD3, and FD4) is configured with at least two storage options, allowing users to choose the best storage solution for their virtual machines based on their IO requirements.
Configuring Storage
Storage type can be set during deployment or updated on existing virtual machines through the ITS Private Cloud Portal or Command Line Interface.
Reviewing Storage Configuration
To quickly review the storage configuration of your virtual machines, execute the following vss-cli command:

Updating Storage Configuration
To update the storage configuration of your virtual machines, use the ITS Private Cloud Portal or Command Line Interface.
Important Considerations
| Note |
|---|
When changing the storage type, a storage vMotion is performed, which may impact IO performance. To minimize disruption, we recommend scheduling the change during a least busy time. Additionally, if your workload is IO-intensive, it is recommended to schedule the change during a maintenance window to ensure minimal impact on your operations. |
