Component locations
You must make sure that you have correctly identified the cable connection for host cabling, drive
shelf cabling, and Ethernet cabling.
The figures included in this section identify the locations of controllers, environmental services
modules or I/O modules (ESMs/IOMs), host ports, drive ports, and Ethernet ports. The figures also
show port identifiers.
Component locations on the E5700 controller shelves
The E5724 controller shelf has twenty-four 2.5 in. drive bays. HDD and SSD drives are supported
with the E5724 models. The E5724 controller shelf is available in duplex (two controllers)
configurations only.
The EF570 controller shelf uses identical component locations to the E5724 controller shelf.
However, the EF570 supports SSD drives only. The EF570 controller shelf is available in duplex
configurations only.
The E5760 controller shelf has five drawers. Each drawer has twelve 3.5 in. drive bays. The E5760 is
available only in the duplex configuration.
Keep these points in mind when you compare the figures in this section to your hardware:
• The top of the controller shelf is the side with the labels.
• The configuration of the host ports depends on which host interface card is installed.
• The E5724, E5760, and EF570 utilize identical controllers.
