Arista Wields Tomahawks In 25G Ethernet Price War

by Jack @ UNIXPlus September 15, 2015

It looks like networking price war is getting set to break out in the largest datacenters of the world, and this is precisely what Google and Microsoft had in mind when they formed the 25G Ethernet consortium back in July 2014.

Unhappy with the bandwidth, cost per bit, and high power consumption and heat dissipation of existing 40 Gb/sec and 100 Gb/sec switches, the two companies teamed up with switch chip makers Broadcom and Mellanox Technologies and switch maker Arista Networks to create a new standard that would offer 25 Gb/sec and 50 Gb/sec switching inside racks and feeding up to 100 Gb/sec in the aggregation and spine layers of the network. The IEEE originally rejected this idea, but came around to endorsing it once it became clear that these companies were happy to create their own standard with or without the IEEE’s blessing.

Now, after much work, the first set of 25G products are getting ready to come to market, and shake things up they will for sure. And we believe, not just for the Googles and Microsofts of the world.

Dell, which sells a slew of custom servers to hyperscalers and cloud builders and is seeking to expand that business to smaller service providers and telcos, was the first to preview the switches it was creating using Broadcom’s “Tomahawk” switch ASICs, which support the 25G protocols and which were previewed last summer. HP has hinted at its plans for the “Tomahawk” ASICs from Broadcom, but has yet to launch products, and Mellanox, which makes switch chips as well as switches, adapters, and cables, unveiled its Spectrum switches and ConnectX-4 adapters back in June, which support 25 Gb/sec, 50 Gb/sec, and 100 Gb/sec speeds. Earlier this year, Dell was talking about Force10 S series switches offering 100 Gb/sec switches based on Tomahawk for under $2,000 per port. The top-end Mellanox Spectrum SN2700 switch has a list price of $49,000, which works out to $1,531 per port. (Other Mellanox switches have not been priced as yet, so we are unsure of how to compare them.)
