Double parity RAID is RAID in which each stripe contains two parity disks. As with triple mirroring, this yields high availability, as data remains available with the failure of any two disks. Double parity RAID is a higher capacity option than the mirroring options and is intended either for high-throughput sequential-access workloads (such as backup) or for storing large amounts of data with low random-read component.

Note: RAIDZ (single parity), Z2 (double parity), Z3 (triple parity)

SunOS STREAMS-based device drivers wishing to support the STREAMS TCP/IP and other STREAMS-based networking protocol suite implementations support Version 2 of the Data Link Provider Interface (DLPI). DLPI V2 enables a data link service user to access and use any of a variety of conforming data link service providers without special knowledge of the provider's protocol. Specifically, the interface is intended to support Ethernet, X.25 LAPB, SDLC, ISDN LAPD, CSMA/CD, FDDI, token ring, token bus, Bisync, and other datalink-level protocols.

Note: The UART interface provides methods for controlling and accessing a UART (Universal Asynchronous Receiver/Transmitter).

Quantized Heat Map: to identify single or multiple devices at 100% utilization, minimum and maximum device utilization, and device utilization balance, all over time (performance analysis).

Resetting the Service Processor Using Oracle ILOM

If the Oracle ILOM service processor (SP) is hung, Oracle ILOM provides two methods to reset it:

From the Oracle ILOM command-line interface (CLI), type: reset /SP.

From the Oracle ILOM web interface, click Administration > Maintenance > Reset SP.

If the Oracle ILOM SP is hung and you cannot reset it using the Oracle ILOM web interface or the Oracle ILOM CLI command, use the following procedure to reset the SP from the server back panel.

Using a stylus, press the Reset SP pinhole button that is located on the server back panel.

When equipped with native QDR InfiniBand and 10Gb Ethernet connectivity options, the ZFS Storage Appliance is ideal for reliably backing up Oracle Exadata.

The Oracle Private Cloud Appliance includes compute nodes, management nodes, virtual networking, and integrated Oracle ZFS Storage ZS3-ES for internal storage.

The new OISP allows the Oracle Database NFSv4 client to pass ODM optimization information to the NFSv4 server of the ZFS Storage Appliance. The ZFS Storage Appliance takes advantage of the ODM optimization information to simplify database configuration and to further increase database performance.
