Comprehensive Management
The rich functionality provided by the Mellanox sRB-20210G is fully integrated into
GridVision™ Grid Interconnect Management Software that is embedded in Mellanox
InfiniBand switches and gateways.
GridVision is an easy-to-use management suite that provides access through a Web-based
GUI, a command line interface (CLI) and SNMP.
Out-of-band management includes InfiniBand, Ethernet and EIA/TIA-232 connections. The
Mellanox sRB-20210G Gateway management is also integrated with leading third party grid
and on-demand management platforms.
1.4.3
sRB-20210G Architecture
All data traffic is handled by the sRB-20210G hardware (Silicon) to achieve the highest
possible throughput, with the lowest possible latency.
Management traffic is handled in software by the CPU.

Supported Protocols
The sRB-20210G supports the following protocols:
10 Gigabit Ethernet over fiber - IEEE 802.3ae - 10GBASE-SR and 10GBASE-LR.
10 Gigabit Ethernet over twin-axial cable
– IEEE 820.3ak – 10GBASE-CX4
InfiniBand 1.1 compliant
IETF RFC 4391 Transmission of IP over InfiniBand (IPoIB)
IETF RFC 4392 IP over InfiniBand (IPoIB) Architecture
SNMP v2c: IETF-RFC190x
Java 1.6 for the GUI.
IPoIB (IP-over-InfiniBand) is a protocol for encapsulating data requests and responses over
InfiniBand. The sRB-20210G uses IP over InfiniBand (IPoIB) protocols in order to provide IP
link between Ethernet network and InfiniBand based network.
The tunneling functionality is achieved by Layer II address translation of an InfiniBand
address to an Ethernet address (MAC) and vice versa.
