Network World - Three switching vendors this week are unveiling new and enhanced data center products, including for those looking to upgrade to 40Gbps Ethernet in the near future.
Start-up Arista Networks unveiled its first modular 10Gbps switch, which allows the company to claim leadership in wire-speed 10G port density. Force10 Networks had recently laid claim to that title.
Extreme Networks rolled out software enhancements to allow customers to better manage virtual machines and reduce the number of switching layers, or tiers, in the data center network. And Force10 announced that it will ship 40Gbps Ethernet switches in the second half of this year.
The announcements indicate that data center switching continues to be the hottest segment of the switching market as users broaden their use of virtualization. Data centers with thousands of servers, each housing scores of VMs, require increased bandwidth and more granular management to maintain control over the spread of the virtual workload.
Arista is hitting the increased bandwidth requirement with the AN 7500 switch. The chassis-based core switch complements the company's existing 1/10G top-of-rack devices for connecting racks of servers to the data center core.
The eight-slot 7500 is 11 rack-units high with a 10Tbps switching capacity and 384 wire-speed L2/L3 10Gbps Ethernet ports. This surpasses Force10's previous wire-speed 10G density lead with 140 ports in its ExaScale E1200 core switch -- though it claims to support another 420 oversubscribed ports.
The 7500 also features 13 watts of power consumption per port -- or about 25% that of its "greenest" competitor -- and throughput of 5.76 billion packets per second in a single chassis, Arista claims. This kind of performance, along with the 10Tbps switching capacity, will allow the switch to support 40G and 100Gbps Ethernet interfaces in the future.
Arista CEO Jayshree Ullal would not say how far -- or close -- into the future those interfaces will emerge but said the company has 40G modules in its development labs and that they may sport "more than one or two" interfaces.
Theoretically, at 10Tbps, the 7500 could support 250 40G Ethernet ports.
"If it turns out to be the switch they say it is, it's going to have a huge impact on the [high performance computing] market," says Steve Schuchart of Current Analysis. "They could be a game changer."
In addition to the Force10 E-Series, the 7500 will go up against Cisco's Nexus 7010, Juniper's EX8216 and Brocade's MLX-32.
The Arista 7500 starts at $140,000 and a fully configured system is less than $1,200 per wire-speed port, the company says.
Competitor Extreme is enhancing its current switches with software to help manage the growth of VMs, and reduce the number of switching tiers in a data center.
Extreme's XNV software is designed to allow network administrators to manage the life cycle of VMs. It's an add-on software module to the company's ExtremeXOS operating system and EPICenter management system.
