Table 1-2 Endurance Components
Component Description
Endurance
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 Endurance
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 Endurance server are:
• ESI11 from IOP1 to CE1
• ESI12 from IOP1 to CE2
• ESI21 from IOP2 to CE1
• ESI22 from IOP2 to CE2 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 Endurance 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 Endurance server and a local area network. 2
Tuple Tuple is a conceptual term used to describe half of the
redundant devices in the Endurance server. There are two
tuples in the Endurance 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 Endurance server. Each CE and IOP
contains a MIC. 4
