An S32 Node has two networks for connecting to your networking infrastructure: an access network and a management network. Both the access network and the management network can be used for management functions. Only the access network can be used for data access.
Access network
For the access network, each server module comes with two onboard 25/10Gb Ethernet SFP28 ports. These ports can be used with an SFP28 networking infrastructure at a speed of 25 Gb or connected to an SFP+ networking infrastructure at a speed of 10 Gb.
The access network ports can be configured as active-active (802.3ad) or active-backup. To create a highly available infrastructure, the ports can be connected to different physical switches.
You can choose not to connect one of the access network ports to the networking infrastructure. In this case, the access network uses only a single port.
Management network
For the management network, each server module has one 1Gb Ethernet port. You can choose not to connect the management port. In this case, only the access network is available for management functions.
Available additional components
To meet your network connectivity requirements, Hitachi Vantara offers the additional components listed below.
- 25Gb SFP28 optical transceiver
- If you have a 25Gb Ethernet network and are using fiber optic cables for the access network connections, a 25Gb SFP28 optical transceiver is required on both ends of each fiber optic cable. The 25Gb SFP28 optical transceiver has an LC type connector. Hitachi Vantara offers a 25Gb SFP28 optical transceiver from Mellanox.
- The Mellanox 25Gb SFP28 optical transceiver is the only SFP28 optical transceiver supported for use with an S32 Node.
- 10Gb SFP+ optical transceiver
- If you have a 10Gb Ethernet network and are using fiber optic cables for the access network connections, a 10Gb SFP+ optical transceiver is required on both ends of each fiber optic cable. The 10Gb SFP+ optical transceiver has an LC type connector. Hitachi Vantara offers a 10Gb SFP+ optical transceiver from Cisco.
- The Cisco 10Gb SFP+ optical transceiver is the only SFP+ optical transceiver supported for use with an S32 Node.
- Multimode fiber optic cable
- If you have a 10Gb Ethernet network and the distance between the server modules and the Ethernet switches is greater than 10 meters, fiber optic cables must be used for the access network connections. If you have a 25Gb Ethernet network and the distance between the server modules and the Ethernet switches is greater than 5 meters, fiber optic cables must be used for the access network connections.
- Hitachi Vantara offers multimode fiber optic cables in various lengths in both plenum and LSZH jacketing.
- 25Gb or 10Gb Twinax cable
- If you have a 10Gb Ethernet network and the distance between the server modules and the Ethernet switches is less than 10 meters, Twinax cables can be used instead of fiber optic cables for the access network connections. If you have a 25Gb Ethernet network and the distance between the server modules and the Ethernet switches is less than 5 meters, Twinax cables can be used instead of fiber optic cables for the access network connections.
- Hitachi Vantara offers 25Gb Twinax cables in various lengths up to five meters and 10Gb Twinax cables in various lengths. The Twinax cables come from both Brocade and Cisco.
