What Are the Differences Between MBR and GPT Partition Styles?
Table 1 lists the common disk partition styles. In Linux, different partition styles require different partitioning tools.
Disk Partition Style |
Maximum Disk Capacity Supported |
Maximum Number of Partitions Supported |
Linux Partitioning Tool |
---|---|---|---|
Master Boot Record (MBR) |
2 TiB |
With MBR, you can create several primary partitions and one extended partition. The extended partition must be divided into logical partitions before use. For example, if 6 partitions need to be created, you can create them in the following two ways:
|
You can use either of the following tools:
|
Guid Partition Table (GPT) |
18 EiB 1 EiB = 1048576 TiB |
Unlimited Disk partitions created using GPT are not categorized. |
parted |

The maximum disk size supported by MBR is 2 TiB, and that supported by GPT is 18 EiB. Because an EVS data disk currently supports up to 32 TiB, use GPT if your disk size is greater than 2 TiB.
If you change the partition style after the disk has been used, the data on the disk will be cleared. Therefore, select an appropriate partition style when initializing the disk.
