Sophisticated Array Monitoring Tools
Promise Array Management (PAM) software offers professional management tools in a
simple-to-use, straightforward format. Array configurations, management and
monitoring features are available via the windows based management and can be
access locally or via the TCP/IP network remotely. Moreover, the FastTrak SX family
supports industry standard SNMP so third party management application integration is
simplified.
