HP StorageWorks Clustered File System 3.6.1 Windows Storage Server Edition administration guide (AG515 - 96007, August 2008)

Chapter 4: Cluster Administration 22
Tested Configuration Limits
HP has tested HP Clustered File System configurations up to the
following limits:
• 16 servers per cluster
• 256 imported LUNs per cluster for FC configurations;
for iSCSI
configurations, the maximum number of connections for the iSCSI
initiator
• 128 filesystems per cluster on 32-bit systems; 256 filesystems on 64-bit
systems
• 2048 filesystem mounts per cluster
• 128 virtual hosts per cluster
• 128 service and/or device monitors per cluster (the total number of
service and device monitors cannot exceed 128)
• 4 network interface cards per server
• 1 FibreChannel port per server (unless using third-party MPIO
software)
These limits will be increased as additional testing takes place.
Theoretically, the tested configuration limits can be exceeded up to the
bounds of the operating system. If you plan to configure your cluster
beyond the tested limits, please contact HP Support for information about
any known configuration issues or concerns.
Volume and Filesystem Limits
The following limits apply to volumes and filesystems:
• The maximum volume size is 16 TB for 32-bit operating systems and
32 TB for 64-bit operating systems.
• The maximum filesystem size is 16 TB for 32-bit operating systems
and 32 TB for 64-bit operating systems.
• The maximum file size is 2 TB minus one byte. If an I/O operation
would cause the size of a file to exceed this limit, the complete I/O
operation will fail.
