4.1.0 HP PolyServe Matrix Server administration guide (T5392-96073, October 2010)

Volume and filesystem limits
The following limits apply to volumes and filesystems:
• The maximum volume size is 32 TB.
• The maximum filesystem size is 32 TB for the 4 KB and 8 KB block sizes, and
128 TB for the 32 KB block size.
• 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.
Cluster 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 45.)
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 matrix. It can also store
the usernames and passwords needed to access the servers.
• On the command line, the --username and --password options can be used
to provide credentials for an mx command.
• If Matrix Server cannot authenticate a user via the methods above, it prompts for
the username and password.
