Hello @Handian Sudianto
I see you are using the Azure Stack HCI sizing tool, please note this feature is under preview and is explained well in the following tutorial, please go through, it will come handy https://www.youtube.com/watch?v=9CLCZHBKjXc
If you have feedback on this tool you can write to hcisizer@microsoft.com!
As per my understanding the break down of these storage calculations is done this way.
- Used Storage (23 TB): This is the amount of storage currently being utilized by your data and workloads.
- Resiliency (46 TB): This represents the storage capacity allocated to ensure data redundancy and fault tolerance. In Azure Stack HCI, resiliency is achieved through techniques like mirroring or parity, which duplicate or distribute data across multiple drives to protect against hardware failures.
- Leftover (7 TB): This is the unallocated storage capacity that remains after accounting for used storage, resiliency, future growth, and reserve. It acts as a buffer for unexpected storage needs.
- Future Growth (15 TB): This is the storage capacity reserved for anticipated future data growth. It ensures that you have enough space to accommodate new data without needing immediate hardware upgrades.
- Reserve (30 TB): This is the total storage capacity set aside for both resiliency and future growth. It includes the 46 TB for resiliency and the 15 TB for future growth, ensuring that your system can handle both current and future demands. The reserve of 30 TB is part of the total storage capacity, ensuring that your system remains scalable and resilient.
