Component Description
HP NetServer AA
Server Contains . .
.
CE Each CE (Compute Element) is a Pentium class system that
includes a motherboard, video adapter, a MIC (Marathon
Interface Card), and two processors. The processors on the CE
provide the compute processing for the server.
2
ESI The Endurance System Interconnect (ESI) is a conceptual term
used to describe the fiber paths that connect the IOPs to the CEs.
The ESI paths in the server are:
• ESI11 from IOP1 to CE1
• ESI12 from IOP1 to CE2
• ESI21 from IOP2 to CE1
• ESI22 from IOP2 to CE2
You can monitor and manage the ESIs using Endurance Manager.
4
IOP Each IOP (I/O Processor) is a Pentium-based system that includes
a floppy disk drive; SCSI devices; SCSI, video and Ethernet
adapters; a keyboard; a mouse; serial ports; and a MIC. The
processors on the IOP provide the I/O processing, data storage
network connectivity, and redundant I/O resources for the server.
2
IL The IL (IOP Link) provides a path for communicating system
states and status information. It also provides a mirror copy data
path.
1
Network
Connection
Each network connection provides a communication path between
the server and a local area network.
2
Tuple Tuple is a conceptual term used to describe half of the redundant
devices in the server. There are two tuples in the server. Each tuple
contains:
• a CE
• an IOP
• a network connection
2
MIC The MIC (Marathon Interface Card) supports a high-speed
interconnect path for communication between the CE and IOP
components in the server. Each CE and IOP contains a MIC.
