A server power cord AC receptacle.
Memory buffer on board. An ASIC on a CMU board that transfers data between a DIMM and a CMP.
A type of PDomain which is limited to one DCU. A Bounded PDomain will typically exhibit higher performance as all resources are local to the single DCU. Bounded PDomains are not subject to SSB failure. Bounded PDomains can contain up to eight CMPs.
Label of the PCIe hot-plug carrier.
Cubic feet per minute.
Label for a clock board. The sever contains two dual-redundant clock boards.
Chip multiprocessing. Each CMU contains two CMP processors. The server can contain a maximum of 32 CMPs.
CPU memory unit. Each CMU contains two CMPs and two sets of DIMM slots.
Domain configuration management. DCM refers to the reconfiguration of boards in physical domains for Enterprise-class systems.
Domain configurable unit. Each DCU contains two or four CMUs and one IOU. The smallest building block for physical domains.
Dynamic Host Configuration Protocol. Software that automatically assigns IP addresses to clients on a Transmission Control Protocol/Internet Protocol (TCP/IP) network.
Dual in-line memory module.
Express module SAS. Each EMS contains two 10GBASE-T network connections and provides access to four hard drives on the server.
Fault management architecture. Generates fault indictments from the Broken Link (Target ID: Z40010E81010184). FMA provides three system activities: error handling, fault diagnosis, and response.
fault management architecture. Generates fault indictments from the SP. FMA provides three system activities: error handling, fault diagnosis, and response.
Gigabyte. 1 gigabyte = 1024 megabytes.
Hard disk drive. In Oracle Solaris OS output, HDD can refer to hard disk drives or solid state drives (SSDs).
See Oracle ILOM.
I/O unit. The server contains up to four IOUs, one for each DCU. Each IOU supports up to 16 PCIe slots, 8 10GBASE-T ports on 4 EMS modules, and 8 hard drives.
Keyboard video mouse storage.
Line-to-line. Line-to-line voltage is the voltage between any two phases of an AC generator.
A virtual machine comprising a discrete logical grouping of resources that has its own operating system and identity within a single computer system.
The network management port on a SP.
OpenBoot PROM. Firmware that is installed on the server and provides an interface through which you can perform various diagnostic tasks.
Oracle Integrated Lights-Out Manager (Oracle ILOM) firmware.
Oracle Solaris operating system.
Oracle Validation Test Suite. An application that exercises the system, provides hardware validation, and identifies possible faulty components.
Peripheral Component Interconnect Express.
An enclosure used to install and house PCIe cards in the server.
Physical domain. Each PDomain is an independently configurable and bootable entity with full hardware domain isolation for fault isolation and security purposes.The maximum number of PDomains supported is four, which is equal to the number of DCUs. The minimum number of PDomains is one, which can be composed of all available DCUs within the system.
DCUs in a PDomain communicate with other DCUs in the server through the SSBs. If an SSB fails, the PDomain availability will be impacted. Bounded PDomains are limited to one DCU and are not affected by SSB failures.
The lead SPP of a physical domain. The PDomain-SPP manages tasks and provides rKVMS service for that physical domain.
Power-on self test. A diagnostic that runs when the server boots.
Power system distribution board.
Predictive self healing. An Oracle Solaris OS technology that continuously monitors the health of the server and works with Oracle ILOM to take a faulty component offline if needed.
Remote keyboard video mouse and storage.
Root mean square.
Serial attached SCSI.
Serial advance technology attachment.
The serial management port on a SP.
Service processor. For redundancy, the server contains two service processors, one being active and one on standby.
Service processor proxy. One SPP is assigned to manage each PDomain. SPPs monitor environmental sensors and manage the CMUs, memory controllers, and DIMMs within the DCU.
Scalability switch board.
Solid state drive.
Secure shell. A program for logging in and executing commands on a system or service processor.
Terabyte. 1 terabyte = 1024 gigabytes.
A type of screw head characterized by a 6-point star-shaped pattern.
Uninterruptible power supply.
Voltage alternating current.
Virtual local area network.
See Oracle VTS.
World wide name.
