Operational Requirements
The operational requirements for the Universal Storage Platform VM include:
■
LAN connection (or RJ-11 analog phone line) for Hi-Track ®
The Hi-Track maintenance support tool monitors the operation of the Universal Storage
Platform VM, collects hardware status and error data, and transmits this data via LAN (or
modem) to the Hitachi Data Systems Support Center. In the event of a component failure,
Hi-Track reports the failure to the Support Center, with no action required on the part of the user.
Hi-Track enables most problems to be identified and fixed prior to actual failure, and the
advanced redundancy features enable the storage system to remain operational even if one or
more components fail.
■
LAN for Storage Navigator
Hitachi Storage Navigator communicates directly with the Universal Storage Platform VM via
LAN to obtain system configuration and status information and send user-requested commands
to the storage system. Storage Navigator serves as the integrated interface for all Resource
Manager components.
■
Cable length for front-end directors
Table 2-11 lists the cable length requirements for the front-end directors (FEDs) in the Universal
Storage Platform VM.
■
External storage
If you plan to attach external storage to the Universal Storage Platform VM, be sure to include
the appropriate power and space requirements in your planning.
