Arista launches new Broadcom-powered switches, updates OS

  • Looking to better cater to growing use of 25G and 100G Ethernet links within data centers (particularly among cloud service providers and others with high-end performance needs), Arista (NYSE:ANET) has rolled out the 7060CX-32S, a top-of-rack (i.e. "leaf") switch that can deliver 10, 25, 40, 50, and 100G links on 32 ports while consuming a modest 1RU of rack space.
  • Other new Arista switches include the 7260CX-64, which provides 64 100G links in a 2RU chassis, and the 7320CX-32C, modular switches supporting 32 100G ports that can be combined to form 256-port systems. 25G links are increasingly being used to connect servers with top-of-rack switches, while 40G and 100G links are being adopted to aggregate traffic to and from servers.
  • The hardware relies on Broadcom's (BRCM) StrataXGS Tomahawk switching chip, which delivers up to 3.2Tbps of switching capacity. Cisco and Dell have also announced Tomahawk-based switches. Mellanox is looking to challenge Broadcom with its 6.4Tbps Spectrum switching chips (used in 10-100G-capable Mellanox switches), while Cavium is going after the market with its 3.2Tbps Xpliant chips.
  • Also: Arista has added new high-availability features for its EOS OS (powers the company's switches). The features enable software upgrades and port speed changes to occur without any effect on uptime or service quality.
  • Arista remains down 19% from last Tuesday's close, thanks to reports the ITC staff has concluded the company infringes 3 Cisco patents. RBC and SunTrust have defended Arista, with the former arguing Arista might be able to come up with a workaround for Cisco's IP.
