What does having both storage devices configured as GPT disks ensure in Storage Replica?

Having both storage devices configured as GPT (GUID Partition Table) disks ensures compatibility for large volumes, which is crucial for Windows Server environments using Storage Replica. GPT supports larger disk sizes and allows for a greater number of partitions than the older Master Boot Record (MBR) format. This is particularly important for high-capacity storage solutions, where the size of the volumes may exceed the limitations set by MBR.

In a Storage Replica configuration, where data is frequently synchronized and transferred between servers, using GPT disks allows administrators to fully utilize the available storage space without being constrained by size limitations. This is especially beneficial in scenarios where large amounts of data are being replicated, as it ensures that the underlying storage architecture can handle the volume requirements. Additionally, GPT enhances reliability and offers features such as partition redundancy through protective MBR, which can help maintain data integrity during replication processes.

The other options do not specifically relate to the advantages GPT provides in the context of large volume compatibility and may not directly impact the efficient functioning of Storage Replica in the same way.
