Oracle^® Storage 12 Gb/s SAS PCIe RAID HBA, Internal Installation Guide For HBA Models 7110116 and 7110117

HBA Features

The internal Oracle Storage 12 Gb/s SAS PCIe RAID HBA (7110116, 7110117) is a low-profile, PCI Express 3.0 RAID controller that supports eight internal 12 Gb/s SAS/SATA ports through two SFF-8643 x4 internal mini-SAS HD connectors.

Data that is cached on the HBA is protected, in the event of a power failure, by the CacheVault (a super capacitor and flash combination that is installed on the HBA at the factory). If the CacheVault needs to be replaced, for any reason, you can remove the faulty CacheVault from the HBA and obtain a replacement CacheVault from Oracle. For more information about the CacheVault, refer to the Broadcom document, LSICVM02 Kit Quick Installation Guide, located at the Broadcom web site: https://docs.broadcom.com/docs/54063-00

The HBA supports the following features:

• Two SAS3, x4 internal mini-SAS HD connectors

• PCI Express host interface, as defined in the PCI Express Card Specification, version 3.0

• SAS3 12-Gb/s target interface

• PCI Express 3.0 x8 lane width up to 8 Gt/s per lane

• High performance through the MegaRAID Firmware Interface (MFI) architecture

• High throughput and low CPU utilization to offload the host processor

• Boot support for all supported operating systems (OSs) (see Boot Support)

RAID Features

The following are the RAID features supported by the HBA:

• Full-featured, hardware-based RAID implementation

• Integration of a high-speed 1 Gbyte DDR/DDR2 800-MHz on-board SDRAM interface with a hardware RAID assist exclusive-OR (XOR) engine

• Data striping across multiple drives

• Data mirroring or parity block for backing up data

• Support for RAID levels 0, 1, 5, 6, 10, 50, and 60, with a minimum of 1 Gb data cache

• Support for, at minimum, a 72-bit DDR3 memory interface

• Built-in Flash Controller for direct Flash backup from DDR memory

• Support for T10 EEDP (and DIX)

• Dual firmware image (active/backup)

• Support for up to 32 drives in a RAID volume

• Support for several RAID stripe sizes

• Load balancing

• Path failover

• Online RAID level migration

• Drive migration and roaming

• Media scan

• No reboot necessary after expansion

• User-configurable rebuild rate

• 32-Kbyte nonvolatile random access memory (NVRAM) for storing RAID system configuration information; the MegaRAID SAS firmware is stored in flash ROM for easy upgrade
