Disk Management ■ When managing basic disks, only the last partition on the disk can be extended unless the disk is changed to dynamic. ■ Basic disks can be converted to dynamic without bringing the system offline or loss of data, but the volume will be unavailable during the conversion. ■ Basic disks can contain up to four primary partitions (or three primary partitions and one extended partition). ■ Format drives with a 16 K allocation size for best support of snapshots, performance, and defragmentation. ■ NTFS formatted drives are recommend since they provide the greatest level of support for snapshots, encryption, and compression. ■ Only basic disks can be formatted as FAT or FAT32. Dynamic disks are not supported, nor can they be configured in a cluster. Volumes Page On the Volumes page, administrators can select to manage volumes, schedule defragmentation, and set or manage quotas. The Volumes page displays all volumes that are formatted NTFS on the system. It does not display the volume type (for example simple or spanned) nor volumes that are FAT32 or FAT. To display these types of volumes, click Manage. All volumes are displayed. See the Managed Disks page to view a list of disks, and the volumes assigned to them. The drive letters for volumes that encompass multiple disks appear on multiple rows on the display. NAS 4000s and 9000s Administration Guide 77
