In Modern Datacenters, The Latency Tail Wags The Network Dog
The expression, the tail wags the dog, is used when a seemingly unimportant factor or infrequent event actually dominates the situation. …

Drilling Down Into Ethernet Switch Trends
Of the three pillars of the datacenter – compute, storage, and networking – the one that consistently still has some margins and yet does not dominate the overall system budget is networking. …

The Road To 400G Ethernet Is Paved With Bechtolsheim’s Intentions
The best way to make a wave is to make a big splash, which is something that Andy Bechtolsheim, perhaps the most famous serial entrepreneur in IT infrastructure, is very good at doing. …

Flattening Networks – And Budgets – With 400G Ethernet
If it were not for the insatiable bandwidth needs of the twenty major hyperscalers and cloud builders, it is safe to say that the innovation necessary to get Ethernet switching and routing up to 200 Gb/sec or 400 Gb/sec might not have been done at the fast pace that the industry as been able to pull off. …

The Tug Of War Between InfiniBand And Ethernet
If you want to get a microcosmic view of the epic battle between Ethernet and InfiniBand (which also includes Omni-Path no matter how much Intel protests) as they relate to high performance computing in its many modern guises, there is perhaps no better place to look at what Mellanox Technologies is selling. …

A Rare Peek Inside A 400G Cisco Network Chip
Server processor architectures are trying to break the ties between memory and compute to allow the capacities of each to scale independently of each other, but switching and routing giant Cisco Systems has already done this for a high-end switch chip that looks remarkably like a CPU tuned for network processing. …

Signposts On The Roadmap Out To 10 Tb/sec Ethernet
The world of Ethernet switching and routing used to be more predictable than just about any other part of the datacenter, but for the past decade the old adage – ten times the bandwidth for three times the cost – has not held. …
