Arista 10G switch: Fast and flexible
Packing 384 10G Ethernet ports into an 11-rack-unit form factor is only the beginning for Arista Networks' DCS-7508 data center core switch.

If you're considering the move to 40/100gigabit Ethernet, here are five things to keep in mind:
Ten-gigabit Ethernet was so last year.
High port density, high throughput, and very low latency are bedrock requirements in the data center, and Force10's new S4810 top-of-rack switch delivers on all three counts.
Either because server disks are full or because virtualization is a natural growth path, organizations large and small are moving toward shared storage. For large enterprises, high-capacity storage-area networks make sense, but what about small or mid-sized enterprises new to shared storage?
3Com says it has an alternative for network managers considering high-end switches from Cisco and others.
With enterprises looking to consolidate data centers and devices, Cisco's new ASR 1000 series router offers a compelling message: Do more with less.
Building a big data center and looking for a switch to match? How do 256 10 Gigabit Ethernet ports and nearly 1.7 terabits of capacity sound?
Cisco take note: Juniper's new EX 4200 switch not only fills a hole in a leading competitor's product line, but also represents a credible alternative for enterprise access switching.
Here are five questions for enterprise network managers to bear in mind when considering UC deployment:
Unified communications offers the potential for anywhere, anytime connectivity between employees and the enterprise. But as the InteropLabs hotstage team found in piecing together more than a dozen commercial and open-source voice, data and messaging platforms, the technology is still at a relatively early stage, and today represents more promise than practice.
VoIP vendors say they deliver scalability and security. InteropLabs (iLabs) testing mostly proved them right in multivendor settings. But testing also revealed some implementation gotchas in both of those areas, and pinpointed a few missing pieces when it comes to key exchange for securing VoIP traffic.
Faced with big bandwidth bills every month, it's tempting simply to buy the application with the best performance. Tempting, but not necessarily correct.
Network managers driven by frugality, patriotism or both, might want to consider the WideBand WB28GMPRO, a low-cost managed Gigabit Ethernet switch made in the American heartland.
By now, basic interoperability is generally a given in multivendor VoIP settings. What happens, however, when VoIP devices go to work in decidedly unfriendly environments, such as through security devices and across wireless LANs?
