A customer is purchasing a 1-node E870 and requires the following:
Two NICs
Five HBAs
Internal disk drives with redundant VIOS
What can be added to the E870 to satisfy their requirement?

A.
Redundant SAS controllers and an EXP24S in mode 4.

B.
An EXP24S in mode 2 connected to the integrated SAS controller.

C.
A PCIe I/O Drawer, redundant SAS controllers, and an EXP24S in mode 1.

D.
Two PCIe I/O Drawers, redundant SAS controllers, and an EXP24S in mode 2.

Explanation:
The EXP24S SFF Gen2-bay Drawer (#5887) is an expansion drawer with twenty-four 2.5-inch form-factor SAS
bays.
With AIX, Linux, and VIOS, you can order the EXP24S with four sets of six bays, two sets of 12 bays, or one
set of 24 bays (mode 4, 2, or 1).
It is recommended for SAS cabling ease that the EXP24S drawer be located in the same rack in which the
PCIe adapter is located. Note, however, it is often a good availability practice to split a SAS adapter pair across
two PCIe drawers/nodes for availability and that may make the SAS cabling ease recommendation difficult or
impossible to implement.
Incorrect Answers:
B: To maximize configuration flexibility and space utilization, the E870 system node does not have integrated
SAS bays or integrated SAS controllers. PCIe adapters and the EXP24S can be used to provide direct access
storage.
