Required Disk Space for Installation

1GB

Operating System

Linux operating system.

For the list of supported operating system distributions and kernels, please refer to the DOCA-Host Release Notes.

Installer Privileges

The installation requires administrator (root) privileges on the target machine.

Single-port Socket Direct Card/MultiHost (2x PCIe x16)

Dual-port Socket Direct Card/MultiHost (2x PCIe x16)

            

            
82:00.0 Ethernet controller: Mellanox Technologies CX8 Family [ConnectX-9]
82:00.1 Ethernet controller: Mellanox Technologies CX8 Family [ConnectX-9]
84:00.0 Ethernet controller: Mellanox Technologies CX8 Family [ConnectX-9]
84:00.1 Ethernet controller: Mellanox Technologies CX8 Family [ConnectX-9]
        

In the output example above, the first two rows indicate that one card is installed in a PCI slot with PCI Bus address 05 (hexadecimal), PCI Device number 00, and PCI Function numbers 0 and 1. The other card is installed in a PCI slot with PCI Bus address 82 (hexadecimal), PCI Device number 00, and PCI Function numbers 0 and 1.

Since the two PCIe cards are installed in two PCIe slots, each card gets a unique PCI Bus and Device number. Each of the PCIe x16 busses sees two network ports; in effect, the two physical ports of the ConnectX-7 Socket Direct adapter are viewed as four net devices by the system.
