Oracle ZFS Storage ZS9-2 PCIe Card Configuration

The 10 PCIe slots are located inside the controller at the back. As viewed from the back of the controller, the slots are divided into two groups, a group of five to the left of the built-in network ports and rear indicators and a group of five to the right side of the network ports and indicators. The PCIe slots are designated from left to right (back view) with the five slots on the left side designated as PCIe Slot 1 to PCIe Slot 5, and the five slots on the right side designated as PCIe Slot 6 to PCIe Slot 10. The following figure shows the Oracle ZFS Storage ZS9-2 high-end model.

1 Second PCIe option	2 Third PCIe option	3 Fifth PCIe option
4 External SAS-3 HBA	5 HBA or filler panel High-end model: External SAS-3 HBA Mid-range model: Filler panel; slot not available	6 Cluster interface Ethernet adapter
7 First PCIe option	8 HBA or filler panel High-end model: External SAS-3 HBA Mid-range model: Filler panel; slot not available	9 External SAS-3 HBA
10 Fourth PCIe option

PCIe Slot Width and Capabilities

The controller contains 10 low-profile PCIe 4.0 card slots, which have the following width and capabilities:

• Slots 3 and 10 have x16 connectors with x16 electrical interface

• Slots 1 and 2 have x16 connectors with x8 electrical interface

• Slots 4, 5, 6, 7, 8, and 9 have x8 connectors (x8 electrical interface)

Note:

While slots 1 and 2 can accommodate a x16-width card, the capability of the card will be limited by the x8 electrical interface.

PCIe Card Slot Population Order

Each base unit Oracle ZFS Storage ZS9-2 is always loaded with the following PCIe adapters or fillers:

• Slot 4: 4x4 SAS-3 HBA

• Slot 5: 4x4 SAS-3 HBA high-end model; filler panel mid-range model (slot not available)

• Slot 6: Cluster interface Ethernet adapter

• Slot 8: 4x4 SAS-3 HBA high-end model; filler panel mid-range model (slot not available)

• Slot 9: 4x4 SAS-3 HBA

All allowable option Oracle ZFS Storage ZS9-2 PCIe cards should be installed in the remaining card slot locations and filled in accordance to the following priority and sequence as follows:

1. Install optional dual port 100GbE NIC cards into slot 3, then slot 10.

2. Install optional dual port 25GbE NIC cards into slot 7, then slot 1, then slot 2, then slot 10, then slot 3.

3. Install optional dual port 40GbE NIC cards into slot 7, then slot 1, then slot 2, then slot 10, then slot 3.

4. Install optional dual port 32Gb FC HBA cards into slot 7, then slot 1, then slot 2, then slot 10, then slot 3.

5. Install optional quad port 10GBASE-T NIC cards into slot 7, then slot 1, then slot 2, then slot 10, then slot 3.
