Utilizing Storage Elements; Clustered Server Elements - HP ML110 G1 User Manual

Shadow Copies of Shared Folders resides within this infrastructure and
helps alleviate data loss by creating shadow copies of files or folders that
are stored on network file shares at pre-determined time intervals. In
essence, a shadow copy is a previous version of the file or folder at a
specific point in time.
By using shadow copies, a storage server can maintain a set of previous
versions of all files on the selected volumes. End users access the file or
folder by using a separate client add-on program, which enables them to
view the file in Windows Explorer.
Shadow copies should not replace the current backup, archive, or
business recovery system, but they can help to simplify restore
procedures. For example, shadow copies cannot protect against data
loss due to media failures, however, recovering data from shadow copies
can reduce the number of times needed to restore data from tape.
Detailed information on Shadow Copies can be found in the
administration guide.

Utilizing Storage Elements

No matter which type of storage element is created in the WebUI the last
step in creating the element is determining its drive letter or mount point
and formatting the element. Each element created can exist as a drive
letter(s), assuming one is available and/or as mount points off of an
existing folder of a drive letter. Either method is supported. However,
mount points can not be utilized for shares that will be shared using
Microsoft Services for Unix (NFS). They can be setup with both but the
use of the mount point in conjunction with NFS shares causes instability
with the NFS shares.
Formats consist of NTFS, FAT32, and FAT and all three types can be used
on the storage server. However, the Volume Shadow Copy Service can
only utilize volumes that are NTFS formatted. Also, quota management is
possible only on NTFS.

Clustered Server Elements

Select storage servers support clustering. The HP ProLiant Storage Server
supports several file-sharing protocols, including DFS, NFS, FTP, HTTP,
and Microsoft SMB. Only NFS, FTP, and Microsoft SMB are cluster-aware
protocols. HTTP can be installed on each node but the protocols cannot
be set up through cluster administrator, nor will they failover during a
node failure.
CAUTION:
resources as this is not supported by Microsoft Clustering and data loss
may occur.
AppleTalk shares should not be created on clustered
