cards, redundant PCIe paths to Flash Express cards are provided by redundant I/O
interconnect. Unlike other PCIe I/O cards, they can be accessed from the host only by a
unique protocol.
A Flash Express PCIe adapter integrates four SSD cards of 400 GB each for a total of 1.4 TB
of usable data per card, as shown in Figure H-2.
Figure H-2 Flash Express PCIe adapter
Each card (of a pair of cards) is installed in a PCIe I/O drawer in two different I/O domains. A
maximum of two pairs are installed in a drawer with only one flash card per domain. Installing
more than two pairs requires a second PCIe I/O drawer. Install the cards in the front of the
installed drawers (slots 1 and 14) before you use the rear slots (25 and 33). Format each pair
of cards before you use them.
Figure H-3 shows a PCIe I/O drawer that is fully populated with Flash Express cards.
