Avaya beefs up switch architecture to compete with Cisco, HP, others

Jim Duffy | Nov. 17, 2011
Avaya this week rolled out extensions to its 4000 series switches and said its year-old virtualized networking architecture is taking hold in campuses and data centers.

"They've done a good job pushing it into Nortel," Kerravala says, "but their next area should be the Avaya phone base, which has a lot of HP Procurve."

New: ERS 4800s

New in the 4000 family is the ERS 4800, a group of four Gigabit Ethernet switches in a variety of configurations.

For example, the ERS 4826GTS includes 24 ports of 10/100/1000Mbps Ethernet, including two shared Gigabit Ethernet SFP uplink ports, plus two additional 10G Ethernet SFP+ uplink ports. The ERS 4826GTS-PWR+ includes 24 ports of 10/100/1000 with PoE/PoE+, including two shared SFP uplinks and two additional SFP+ uplink ports.

The ERS 4850GTS carries 48 ports of 10/100/1000, including two shared SFP uplink ports, plus two additional SFP+ uplink ports. And the ERS 4850GTS-PWR+ includes 48 ports of 10/100/1000 with PoE/PoE+ and two shared SFP uplink ports, plus two additional SFP+ uplinks.

The switches feature fabric performance of 128G to 184Gbps, and a frame forwarding rate of 66M to 102Mpps. Latency is 9 microseconds, Avaya says. They support up to 1,024 port/protocol/802.1Q-based VLANs, 8,000 media access control addresses and up to 512 IPv4 routes.

More: ERS 4500s and ERS 4000 software

Avaya also added two new models to its ERS 4500 Fast Ethernet line that both support PoE+. The ERS 4526T-PWR+ includes 24 10/100 ports with PoE/PoE+, plus two 10/100/1000 SFP uplink ports. The ERS 4550T-PWR+ features 48 10/100 ports with PoE/PoE+, plus two 10/100/1000 SFP uplink ports.

In addition to PoE and PoE+, the new ERS 4000 software - Version 5.6 - includes support for redundant field-replaceable AC power supplies on all new models; increased CPU and Flash memory; stackable chassis compatibility with all 4500 models; future support for IPv6, Wireless Split-Plane and the Virtual Services Fabric on the 4800 line; Equal Cost Multi-Path routing; IGMPv3 snooping and proxy; and increased VLAN scaling.

Avaya's Wireless Split-Plane technology decouples wired and wireless control and data traffic in order to ensure that wireless data takes the most optimal path across the network. The company's Virtual Services Fabric is designed to extend the reach of virtualized services from the data center to the campus edge to support the peer-to-peer traffic of collaborative applications like video, and data center-based desktop virtualization applications.

The ERS 4800 line starts at $5,295. The ERS 4500 starts at $3,295. Both v5.6 lines will be available at the end of the month.
