nieuwe partitie aanmaken met disk alignment
Als je een nieuw LUN aanbied vanuit een SAN is het met klem te adviseren deze partitie aan te maken met de juiste alignment. Kort gezegd scheelt dit in performance ;). Hier kort en krachtig de stappen:
- If the disk you are aligning is already blank (raw), proceed to Step 3. If the disk contains data, backup the disk before proceeding.
- Delete all partitions on the disk.
- Open a command prompt, and execute Diskpart.exe.
- At the Diskpart command prompt, type List Disk and press Enter. If the disk you want to align does not appear in the list make sure that it exists and is accessible using the Disk Management snap-in.
- At the Diskpart command prompt, type Select Disk X, where X is the number of the disk as shown in the output of the List Disk command. Diskpart should return a message that indicates that Disk X is the selected disk.
- At the Diskpart command prompt, type Create Partition Primary Align=X, where X is either 32 or 64, depending on the recommendation from your storage vendor. If your storage vendor does not have any specific recommendations, it is recommended that you use 64.
- At the Diskpart command prompt, type Assign Letter=<DriveLetter>. For example, to assign letter Z to the disk, type Assign Letter=Y.
- Once the drive letter is assigned, type exit to exit out of the Diskpart utility.
- Use the Disk Management snap-in or the Windows Format command to format the partition as an NTFS-formatted partition.
