This topic uses Windows Server 2008 R2 Enterprise 64bit to describe how to initialize a data disk attached to a server running Windows.
The maximum disk capacity supported by MBR is 2 TB, and that supported by GPT is 18 EB. Therefore, use the GPT partition style if your disk capacity is greater than 2 TB. For details about disk partition styles, see Introduction to Data Disk Initialization Scenarios and Partition Styles.
The method for initializing an EVS disk varies depending on the OS running on the server. This document is used for reference only. For the detailed operations and differences, see the product documents of the OSs running on the corresponding servers.
The Server Manager window is displayed.
The Disk Management window is displayed.
After making the disk online, right-click the disk status and choose Initialize Disk.
The maximum disk capacity supported by MBR is 2 TB, and that supported by GPT is 18 EB. Currently, an EVS data disk supports up to 32 TB. Therefore, use the GPT partition style if your disk capacity is greater than 2 TB.
If you change the disk partition style after the disk has been used, the original data on the disk will be cleared. Therefore, select a proper disk partition style when initializing the disk.
The partition sizes supported by file systems vary. Therefore, you are advised to choose an appropriate file system based on your service requirements.
