1-8 Sun StorEdge 6320 System 1.0 Reference and Service Manual • May 2003
StorEdge 6320 systems can provide for direct connectivity of five partner groups
of hosts connections. Additional host connections can be achieved using external
switches.
■
Local or Remote Serviceability – The Sun StorEdge 6320 system includes a
Storage Service Processor. Support for the Sun StorEdge Remote Response
software is built into the Storage Service Processor. All configurations are Sun
StorEdge Remote Response ready. Local serviceability and management is
provided by IP Ethernet connectivity to the Storage Service Processor.
■
Hot-Swappable FRUs – The Sun StorEdge 6320 systems use hot-swappable field-
replaceable units (FRUs). The FRUs include power supplies and cooling units
(PCU), batteries, disk drives, loop cards, and RAID controllers. The Storage
Service Processor is a FRU. The FC switches, Storage Service Processor, and
Ethernet hub can be replaced without rebooting the Sun StorEdge 6020 arrays.
Not all FRUs can be replaced by customers. The Storage Service Processor,
Storage Service Processor accessory tray, and the service panel must be replaced
by Sun service personnel.
■
Switched and Switchless Configurations – The Sun StorEdge 6320 systems
provide both a switched and switchless configuration. The switched configuration
is delivered with Sun StorEdge network FC switch-16 switches. A switchless
version is supported. With switchless configurations you can use other front-end
switches, can use external switches, or can directly connect to a data host without
the use of a switch. Neither the internal or external switches are connected to the
internal LAN. Instead, they must manage these switches from an outside Ethernet
connection. Configurations without front-end switches enable connectivity to
external SANs from any vendor and enable a large number of hosts on the SAN
to access the exported LUNs.
■
Host Connect Support – The Sun StorEdge 6320 system provides native fabric
(F-port) host connectivity. Integrated switches also provide for larger host
connectivity.
■
Remote Lights-Out Power Management – The Sun StorEdge 6320 system
supports remote lights out power management. Power sequencers and a
universal serial bus relay are used to control the power sequencing. This enables
users to remotely shut down the components in the system to save power. The
power down shuts down most of the components in the subsystem. Only the
Storage Service Processor and minimal other components are kept running to
enable a subsequent remote power on operation. Power can be restored remotely
at any time. The remote lights-out power management interface also provides
capability to completely shut down the power to all the components. If power is
completely shut down, it cannot be restored remotely.
■
Online Firmware Upgrades – The Sun StorEdge 6320 system supports online
firmware upgrade of most components. There is 100 percent data availability
during the online firmware upgrade operation. Online upgrade is not supported
on the the firmware of the individual disks.
