3.4.0 Matrix Server Administration Guide

Chapter 2: Matrix Administration 17

Tested Configuration Limits

PolyServe has tested Matrix Server configurations up to the following

limits:

• 16 servers per matrix for FC fabric configurations; six servers per

matrix for iSCSI configurations

• 256 imported LUNs per matrix for FC fabric configurations;

for iSCSI

configurations, the maximum number of connections for the iSCSI

initiator

• 128 filesystems per matrix

• 2048 filesystem mounts per matrix

• 64 virtual hosts per matrix

• 128 service and/or device monitors per matrix (the total number of

service and device monitors cannot exceed 128)

• 10 event notifiers per matrix

• 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 matrix

beyond the tested limits, please contact PolyServe Technical 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.

• The maximum filesystem size is 16 TB.

• 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.
