Operational Requirements - Hitachi Universal Storage Platform VM Installation Planning Manual

Operational Requirements

The operational requirements for the Universal Storage Platform VM
include:
• LAN connection (or 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 2-12
(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.
