6 Sun StorEdge 6920 System Getting Started Guide • May 2004
The configuration of the system is based on requirements for throughput, amount of
storage, and economy. For example, if throughput is more important to you than
economy, you might want your system to use the option 1 storage array
configuration. In contrast, if the amount of available storage is more important to
you than throughput, you might want your system to use the option 2 or 3 storage
array configuration.
A controller tray contains disk drives and built-in RAID management hardware. An
expansion tray contains disk drives only and is managed by a controller tray.
FC I/O connections on the service panel connect to the controller of each array in the
base cabinet. This cabling is attached at the factory before the cabinet is shipped.
For more information about array configuration, see the online help.
Internal and External Networks
The Sun StorEdge 6920 system incorporates three separate networks: The Storage
Service Processor LAN, the internal component LAN, and the site (customer) LAN
(
TABLE 1-3
).
Note – In addition to the firewall supplied with the Sun StorEdge 6920 system, you
can also use a site firewall implemented with your own corporate security policies.
However, you cannot use your own firewall in place of the firewall supplied with
the Sun StorEdge 6920 system.
TABLE 1-3
Internal and External LANs
Network Description
Storage Service Processor LAN The Storage Service Processor LAN is used by the Sun StorEdge Remote
Response system to remotely monitor the Sun StorEdge 6920 system.
When multiple Sun StorEdge 6920 systems (up to eight at the same site)
are installed, the systems can share a single telephone line.
Internal Component LAN The Storage Service Processor communicates with components that make
up the system over this LAN. This network is not accessible from outside
the system and is isolated from the data path.
Site (customer) LAN This LAN connects to the customer’s internal Ethernet LAN. This network
enables access to the system from the user’s management host. The
management host is used to configure, control, and monitor the system
through a web browser or a thin-scripting client. A firewall is included in the
router of the Storage Service Processor accessory tray between the user
LAN and the Storage Service Processor LAN.
