Scheduling Defragmentation; Disk Quotas - HP StoreEasy 1000 Administrator's Manual

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 shadow copies, performance,
and defragmentation.
NTFS formatted drives are recommended because they provide the greatest level of support
for de-duplication shadow copies, encryption, and compression.
The size of the NTFS volumes should be limited to 64TB or smaller in size if you are wanting
to use De-duplication or Volume Shadow Copy Server (VSS). De-duplication and VSS do
not support volumes larger than 64TB volumes. Also, writable snapshots or snapshots larger
than 64 TB are not supported.
Basic disks that are larger than 2TB should be formatted in GUID partition table (GPT) style.
For further information refer to the Disk Management help found in the utility.

Scheduling defragmentation

Defragmentation is the process of analyzing local volumes and consolidating fragmented files
and folders so that each occupies a single, contiguous space on the volume. This improves file
system performance. Because defragmentation consolidates files and folders, it also consolidates
the free space on a volume. This reduces the likelihood that new files will be fragmented.
Defragmentation for a volume can be scheduled to occur automatically at convenient times.
Defragmentation can also be done once, or on a recurring basis.
NOTE: Scheduling defragmentation to run no later than a specific time prevents the
defragmentation process from running later than that time. If the defragmentation process is
running when the time is reached, the process is stopped. This setting is useful to ensure that
the defragmentation process ends before the demand for server access is likely to increase.
If defragmenting volumes on which shadow copies are enabled, use a cluster (or allocation unit)
size of 16 KB or larger during the format. Otherwise defragmentation registers as a change by
the Shadow Copy process. This increase in the number of changes forces Shadow Copy to
delete snapshots as the limit for the cache file is reached.
CAUTION:
reformatted drive cannot be recovered.
For more information about disk defragmentation, read the online help.

Disk quotas

Disk quotas track and control disk space use in volumes.
NOTE: To limit the size of a folder or share, see
Configure the volumes on the server to perform the following tasks:
Prevent further disk space use and log an event when a user exceeds a specified disk space
limit.
Log an event when a user exceeds a specified disk space warning level.
When enabling disk quotas, it is possible to set both the disk quota limit and the disk quota
warning level. The disk quota limit specifies the amount of disk space a user is allowed to use.
The warning level specifies the point at which a user is nearing his or her quota limit. For example,
a user's disk quota limit can be set to 50 megabytes (MB), and the disk quota warning level to
45 MB. In this case, the user can store no more than 50 MB on the volume. If the user stores
more than 45 MB on the volume, the disk quota system logs a system event.
Allocation unit size cannot be altered without reformatting the drive. Data on a
