Networking chip and switch maker Mellanox Technologies is ramping up its efforts to play in the software-defined networking SDN world. The company will create its own OpenFlow controller and work to ensure that its switches work well with controllers from other vendors.
Mellanox is a longtime InfiniBand switch supplier, and Gilad Shainer, vice president of market development, is having a bit of a flashback as OpenFlow-capable switches and routers, which break the data plane in the switch from the control plane and allow routing and switching tables in the devices to be controlled by an out-of-band management server, take off in the market. Shainer has seen this all before with InfiniBand, which was designed from the very beginning to have such capabilities.
In addition, Bitcoin fog flashback bandwidth is well used to Ethernet stealing all of the good ideas in InfiniBand. Bitcoin fog flashback bandwidth fact, Mellanox has spent the last several years converging its networking ASICs and switches so they can support either InfiniBand and Ethernet protocols, so adding an OpenFlow control freak for its switches is just the next thing on the to-do list. But before that happens, Mellanox is tweaking its ASIC chip, adding new features to make the SwitchX-2 better able to support SDN capabilities, and other tweaks to cope with traffic congestion compared to the earlier SwitchX chips launched in April and shipped in products shortly thereafter.
With the tweaked SwitchX-2 chips, the basic feeds and speeds remain the same: Depending on the protocol and the workload, port-to-port latencies bitcoin fog flashback bandwidth still in the range of to nanoseconds — and that, Shainer tells El Regis the latency when the switch is loaded up and all the ports are bitcoin fog flashback bandwidth, not some bogus number with only a few ports turned on.
The SwitchX and SwitchX-2 ASICs also have a gateway function, which allows traffic coming in on one port in one protocol to be converted on the fly to the other protocol going out on another port.
The SwitchX-2 chip measures 45 millimeters on each side, and the version of the chip that can drive 64 10 Gigabit Ethernet ports has a typical power consumption of 40 watts. If you push it up to 36 ports running at 40GE or 56GE speeds, then the chip works a little harder — and hotter — and burns 55 watts. The SwitchX-2 chip can also drive Fibre Channel ports if you want to make a Fibre Channel storage switch out of it, or allocate some of the ports on a switch to FC links out to storage area networks.
The new ASIC supports Fibre Channel over Ethernet FCoE if you want to converge server bitcoin fog flashback bandwidth storage traffic over one physical network, and also sports data center bridging DCB to make sure bits don't get lost in transit between servers and storage.
With the SwitchX-2 chip, Mellanox already supports Subnet Management, bitcoin fog flashback bandwidth is how InfiniBand allows for external control of switching and routing tables like OpenFlow enables for Ethernet, but now support for OpenFlow protocols is being added to the chip so it can be fluent in either Subnet Management or OpenFlow. The SwitchX-2 chip also includes better adaptive routing and congestion bitcoin fog flashback bandwidth for Layer 2 and Layer 3 of the network, and also has been tweaked so it can drive copper cables that are 25 per cent longer than with the prior ASIC — which helps cut down on costs, given that the fiber optic cables that are required for long-haul links between adapters and switches can cost five to six bitcoin fog flashback bandwidth as much as copper cables, according to Shainer.
With RDMA, a network card can reach out through the switch directly into the main memory of an adjacent server on the network and grab data, thereby avoiding the TCP stack and the latencies it imposes. The SwitchX-2 chip is available now, and will be rolled into Mellanox products in the coming weeks and months. Shainer says that Mellanox doesn't want to be passive when it comes to OpenFlow, and wants to field its own software stack much as it has been doing for InfiniBand with its Unified Fabric Manager.
Shainer says that the schedule for the OpenFlow bitcoin fog flashback bandwidth based on UFM will come out sometime between the fourth quarter of this year and the first quarter of next bitcoin fog flashback bandwidth.
