Adapter Overview
The content in this document applies to the following Oracle Dual Port 25/100 Gb
Mellanox Ethernet Adapters:
-
Oracle Dual Port 25 Gb Ethernet Adapter, Mellanox
-
Oracle Dual Port 100 Gb Ethernet Adapter, Mellanox
Note -
Performance may be limited depending on the server configuration in which
the 100 GbE Adapter Card is being used. Maximum performance of the 100 GbE
Adapter Card can only be achieved on systems supporting PCIe 4.0 with 16
data lanes.
-
Oracle Dual Port 100 Gb Ethernet Adapter, Mellanox for Mezzanine form factor
(for factory installation) (X86 Server Support Only).
Note -
The Dual Port 25/100 Gb Mellanox Ethernet Adapters are based on the Mellanox
ConnectX®-5 integrated circuit devices.

| Bus type | -
25 GbE Adapter: PCIe 4.0: SERDES @ 8.0GT/s, 8 lanes (2.0
and 1.1 compatible) -
100 GbE Adapter: PCIe 4.0: SERDES @ 8.0GT/s, 16 lanes (2.0
and 1.1 compatible) -
100 GbE Adapter, Mezzanine Form Factor: PCIe 4.0: SERDES @
8.0GT/s x16 lanes (2.0 and 1.1 compatible) (X86 Server
Support Only)

| Bus width | -
25 GbE Adapter: 8-lane PCIe bus connector -
100 GbE Adapter: PCIe 4.0 x16 bus can supply a maximum
bandwidth of 128Gb/s only (=16 * 8GT/s, including
overhead),and therefore cannot support 200Gb/s when both
network ports of MCX556A-ECAT run at 100Gb/s. |

| PreBoot Drivers | Mellanox provided PreBoot drivers are a multiprotocol remote boot technology that support remote Boot over InfiniBand (BoIB) and over Ethernet Using Mellanox Virtual Protocol Interconnect (VPI) technologies
available in ConnectX® adapters, PreBoot drivers give IT
Managers’the choice to boot from a remote storage target (iSCSI
target) or a LAN target (Ethernet Remote Boot Server) using a single
ROM image on Mellanox ConnectX products. FlexBoot is based on the
open source project iPX. |
