The COM Port Upgrade Kit, part number 7Z17A02577, is used for mounting the external serial port on the
rear of the SR590. This option includes the bracket and the cable. The COM Port option is mounted in place
of the PCIe slot 4, and the PCIe slot 4 cannot be used.
Network adapters
The SR590 server has two onboard 1 GbE ports (no 10/100 Mb support) and up to two additional onboard
1/10 GbE network ports (no 10/100 Mb support) with optional LOM cards. Onboard ports and LOM cards
use the Intel Ethernet Connection X722 1/10 GbE technology integrated into the Intel C622 Platform
Controller Hub (PCH). The server also supports ML2 adapters that are installed in the custom ML2 slot
provided by an ML2 riser card. The LOM cards support direct connectivity to the XClarity Controller via the
Network Controller Sideband Interface (NSCI) for out-of-band systems management.
Note: ML2 network adapters do not support NSCI when used in the SR590 server.
The integrated Intel Ethernet Connection X722 has the following features:
Two 1 Gb Ethernet ports (no 10/100 Mb Ethernet support)
Two 1/10 Gb Ethernet capable ports (no 10/100 Mb Ethernet support)
NIC Teaming (load balancing and failover)
DataCenter Bridging
iWARP (RDMA over IP)
VMDq and SR-IOV virtualization (10 Gb speeds only, 4 PFs, 128 VFs per device)
IEEE 802.1q Virtual Local Area Networks (VLANs)
NVGRE, VXLAN, IPinGRE, and MACinUDP network virtualization
IEEE 802.1Qbg Edge Virtual Bridging
TCP, IP, and UDP checksum offload
Large Send Offload (LSO) and Generic Send Offload (GSO)
Receive Side Scaling (RSS) for TCP and UDP traffic
Jumbo frames up to 9.5 Kbytes
