Support for RAID Storage Configurations

By attaching one or more external storage devices to the Sun Fire V490 server, you can use a software RAID application, such as Sun StorEdge™, to configure system disk storage in a variety of different RAID levels. Configuration options include RAID 0 (striping), RAID 1 (mirroring), RAID 0+1 (striping plus mirroring), RAID 1+0 (mirroring plus striping), and RAID 5 (striping with interleaved parity). You choose the appropriate RAID configuration based on the price, performance, and reliability and availability goals for your system. You can also configure one or more drives to serve as “hot spares” to fill in automatically for a defective drive in the event of a disk failure.

Error Correction and Parity Checking

Error correcting code (ECC) is used on all internal system data paths to ensure high levels of data integrity. All data that moves between processors, memory, and PCI bridge chips have end-to-end ECC protection.

The system reports and logs correctable ECC errors. A correctable ECC error is any single-bit error in a 128-bit field. Such errors are corrected as soon as they are detected. The ECC implementation can also detect double-bit errors in the same 128-bit field and multiple-bit errors in the same nibble (4 bits).

In addition to providing ECC protection for data, the system offers parity protection on all system address buses. Parity protection is also used on the PCI and SCSI buses, and in the UltraSPARC IV processors’ internal and external caches.
