3.7.0 HP StorageWorks HP Scalable NAS File Serving Software administration guide - HP Scalable NAS 3.7 for Linux (AG513-96002, October 2009)

FS Option for Linux
FS Option for Linux has been tested to the following configuration limits:
• 128 Virtual NFS Services per cluster.
• 64 Export Groups per cluster.
• 1024 export records per Export Group.
• 512 PSFS filesystems exported via NFS per cluster.
Dynamic volumes
The configuration limits for dynamic volumes are as follows:
• A maximum size of 128 TB for a dynamic volume.
• A maximum of 512 dynamic volumes per cluster.
• A maximum of 128 subdevices per dynamic volume.
• Concatenated dynamic volumes can be extended up to 128 times; however, the
total number of subdevices cannot exceed 128.
• Striped dynamic volumes can be extended up to 16 times; however, the total
number of subdevices cannot exceed 128.
Filesystem limits
The following limits apply to filesystems:
• The maximum filesystem size is 128 TB.
• The maximum file size is 2 TB. The PSFS filesystem does not prevent the creation
of files larger than 2TB; however, such files will not be treated correctly by quotas
or size reporting utilities such as ls.
Cluster management applications
HP Scalable NAS provides two management applications: mxconsole, the
Management Console, and mx, the corresponding command-line interface. These
applications can be run from either a cluster server or a local machine outside the
cluster.
On a local machine, the management applications download their rendering and
application logic from the servers in the cluster. To minimize startup time, the
downloaded software is cached on the local machine. The local machine then uses
