QTS restricts which type of disk can be used to create SSD cache, storage pools, and static volumes.
For compatibility reasons, PCIe form-factor SSDs and PCIe M.2 SSDs installed in third-party adapter cards cannot be used to create storage pools and static volumes.
If you are already using NVMe PCIe SSDs for data storage, then your existing storage configuration will not be affected after upgrading to the latest version of QTS.
