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.
• For both dynamic volumes and basic volumes, the maximum number
of files/inodes is limited only by the available space. If zero-length
files are created, the upper bound is similar to the maximum block
count, which is about 2^32.
Matrix Management Applications
Matrix Server provides two applications to manage the matrix: the
PolyServe Management Console, and mx, the corresponding command-
line interface. These applications can be run from either a server in the
matrix or a local machine outside the matrix. Matrix Server also provides
other commands to perform various matrix operations.
The matrix can also be integrated with any management software that
supports standard SNMP protocol. (For more information about using
SNMP, see “Using the Matrix Server SNMP Service” on page 36.)
User Authentication
Matrix Server provides several ways to authorize users to access the
matrix and perform matrix operations:
• Windows single sign-on. Matrix Server uses the Windows credentials
to authorize access to the matrix.
• The Matrix Server .matrixrc file. This optional file is stored on the local
machine and contains connection information for the servers in the
