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 2-10 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.
