About Sun Fire 880 Mass Storage
Features
The FC-AL technology implemented in the Sun Fire 880 mass storage subsystem
significantly enhances the server’s reliability, availability, and serviceability (RAS)
and performance capabilities.
The following table describes Sun Fire 880 mass storage subsystem features that
enhance RAS capabilities.
Features RAS Capabilities
Dual-ported FC-AL disk drives,
dual-loop backplanes, and
multiple FC-AL host adapters These features provide fault tolerance and high
availability of data. You can implement automatic
failover by configuring two independent and
redundant data paths using two FC-AL host adapters
and appropriate multipathing software. If a
component in either path fails, the software
automatically detects the failure and switches all data
transfers to the alternate path. For additional details,
see “About Multipathing Software” on page 148.
Support for RAID software Using a software RAID application (Solstice DiskSuite
or VERITAS Volume Manager), you can ensure high
availability of data through fault tolerance and data
redundancy. For more information, see “About
Volume Management Software” on page 152.
Hot-pluggable disk drives Hot-pluggable disk drives ensure high data
availability and enhanced serviceability. You can
quickly replace a failed disk drive in a powered-on
system, without affecting the rest of the system’s
capabilities. For more information, see “About Internal
Disk Drives” on page 97 and “About Hot-Pluggable
and Hot-Swappable Components” on page 144.
