Hi guys, I have bought some mellanox gear pretty cheap off Ebay. I need to set some time aside to properly read through everything and learn what i am doing. But i am just trying to get it online to do some basic testing and even that seems to be a bit of a pita.<br />
<br />
My setup is blade M1000e with 2x M4001T switches both showing as online. I then have 40Gb NICs in two R730 servers. Both these connections are showing as disconnected. (if they connect direct without the switch they work perfectly)<br />
<br />
I purchased a 56Gb/s card for a blade server and installed that. I then installed OpenSM / mellanox software and i created the mellanox service. I then started the service and the first port came online. I assigned it a static Ip address but none of the other ports came online.<br />
<br />
The documentation for this specific switch is eluding me. If anyone has some information on what i need to do for the config it would be appreciated!<br />
<br />
I have ordered a serial cable to plug in to the device but from what i read, i was led to believe i wouldnt need one as i can use opensm to configure the switches and bring them online.

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.

Switches / Hubs

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.

Networking

Networking hardware includes the physical devices facilitating the use of a computer network. Typically, networking hardware includes gateways, routers, network bridges, modems, wireless access points, networking cables, line drivers, switches, hubs, and repeaters. But it also includes hybrid network devices such as multilayer switches, protocol converters, bridge routers, proxy servers, firewalls, network address translators, multiplexers, network interface controllers, wireless network interface controllers, ISDN terminal adapters and other related hardware.

Networking Hardware-Other

Servers are computing devices that are similar to desktop computers in that they have the same basic components, but are significantly different in size, configuration and purpose. Servers are usually accessed over a network, and many run unattended, without a computer monitor, input device, audio hardware or USB interfaces. Many servers do not have a graphical user interface (GUI), and are configured and managed remotely. Servers typically include hardware redundancy such as dual power supplies, RAID disk systems, and ECC memory, along with extensive pre-boot memory testing and verification. Critical components might be hot swappable, and to guard against overheating, servers might have more powerful fans or use water cooling.
