40 GbE

2

2, 4. These cards require two slots due to their larger size and need for a x16 bus width PCIe slot. They can be installed in slot 2 (slot 1 will be blocked) and/or slot 4 (slot 5 will be blocked).

10 GbE

4

1, 2, 4, 5. These cards can be installed in slots 1, 2, 4, and 5 but cannot be installed in slots 3 and 6 due to hardware restrictions.

1 GbE

6

1, 2, 3, 4, 5, 6. These cards can be installed in slots 1 to 6. If a QAT Compression/Acceleration card is installed in slot 6, you lose that slot.

QAT Compression/Acceleration

1

6 only. The QAT Compression/Acceleration card can only be installed in the CX 7080 appliance, slot 6.

Slot 1

FH (Full-Height)

FL (Full-Length)

When a x16 card is in slot 2, slot 1 can’t be used.

Two-Port 40-GbE Fiber SR4/LR4 cards require x16 bus width slots and are only supported in slots 2 and 4.

HL (Half-Length <= 6.6 in.)

Half-Height: CX 7080 ships with a 3008-8i HBA mezzanine card preinstalled. The CX 7080 requires this mezzanine card for internal PCIe and IO expansion. The CX 5080 doesn’t require a mezzanine card.

Full-Height: The CX 5080 is full-height NIC compatible when a mezzanine card isn’t installed.

Two Mini-SAS-HD cables connect the 3008-8i HBA mezzanine card and the backplane connectors. If these cables are bad or loose, the SSDs won’t function properly. If the 3008-8i HBA mezzanine card fails, the system won’t recognize the SSDs.
