VENA is competing with other network virtualization and fabric architectures from Cisco, Brocade, HP, Dell, IBM, Extreme, Enterasys, Alcatel-Lucent, and others. Though there's less of a footprint for SPB specifically, Turgeon says the VENA message is resonating with customers.
"It's our most successful strategy launch," Turgeon says of VENA. "Today's biggest pain point is around the data center and VM mobility. Done and delivered. And now we're extending new services across the campus with the need for per-box provisioning."
Some analysts see that as a benefit for VENA and similar strategies from Avaya's competitors. "I like that they're extending the fabric to the campus edge... to reduce latency and make applications work better," Kerravala says.
But VENA, and Avaya, are having a hard time extending interest beyond the old Nortel Enterprise Solutions base, he says, even into Avaya's traditional telephony base.
"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.

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.
