What is the maximum number of partitions supported on a GPT disk in windows server 2008?

On a GPT (GUID Partition Table) disk in Windows Server 2008, the maximum number of primary partitions supported is 128. Unlike MBR (Master Boot Record) disks, which are limited to four primary partitions, GPT allows for a larger number of partitions without needing to create extended partitions. Each partition can be up to 9.4 zettabytes in size, depending on the file system used.
