What is maximum RAW capacity per server and what is maximum pool capacity in Winodws Server 2022 when using S2D?

For Server 2019 it was:

Hello @Vladimir Vukovic

This document applies to Windows Server 2022, Windows Server 2019, Windows Server 2016

Azure Stack Hub, Azure Stack HCI version 21H2, Azure Stack HCI version 20H2,

The maximum raw capacity per server in Windows Server 2022 when using Storage Spaces Direct (S2D) is 4 PB (petabytes) for HDDs and 64 TB (terabytes) for SSDs. The maximum pool capacity in Windows Server 2022 when using S2D depends on the number of servers in the cluster, the amount of storage available on each server, and the type of storage media used.

For example, if you have a four-node cluster with each node having 4 PB of raw capacity, the maximum pool capacity would be 16 PB. However, it's important to note that the actual pool capacity may be lower due to factors such as data redundancy, metadata overhead, and reserved capacity for system use.

It's also worth noting that the maximum pool capacity may be limited by other factors such as network bandwidth, CPU and memory resources, and workload characteristics. Therefore, it's important to carefully plan and design your S2D deployment to ensure that it meets your capacity and performance requirements.
