Migrating to 40 Gigabit Ethernet

Preparing for the 40 GbE migration

The majority of organizations still rely on 10 Gigabit Ethernet links to anchor their networks. But unprecedented data growth and the proliferation of new technologies like cloud and virtualization are beginning to push 10 GbE to its limits. While 40 Gigabit Ethernet is the next frontier for many enterprises, its use will become the new normal.

In this SearchNetworking.com guide, find out about the most important factors you should keep in mind when planning your migration from 10 GbE to 40 GbE. Due diligence is critical. In terms of advice that's high on the list, don't pay more than necessary, and be careful you don't end up with bottlenecks or other IT headaches. Finally, learn what vendors like Brocade, Cisco and Juniper Networks are offering in their 40 GbE product rollouts.

40 Gigabit Ethernet: The migration begins

Forward-looking organizations are beginning to roll out 40 GbE switches and routers in order to avoid inevitable performance shortfalls when the old networks are no longer sufficient. But before you begin planning to deploy your own 40 GbE network, check out this expert tip to brush up on the latest advice.

The future of Ethernet: 10 GbE, 40 GbE and 100 GbE

While 40 GbE may be just around the corner, it’s not the final destination. Eventually 40 GbE will be where 10 GbE is now: Outdated, overloaded and in need of an upgrade. Before that happens to you, check out this webcast, where Demartek founder and president Dennis Martin lays out the past, present and probable future of Ethernet, including 10 GbE, 40 GbE, and 100 GbE.

40 GbE technology: Hurry up and wait

40 GbE technology is here, so why are so many enterprises choosing not to adopt it? Many organizations are trying to get as many miles out of their old Ethernet networks as possible, understandably. The time and money it takes to upgrade to 40 GbE is considerable, and the transition from 10 GbE to 40 GbE is much more complicated than going from 1 GbE to 10 GbE. In addition, if you don't upgrade your entire system, it might actually run worse than your old one due to bottlenecks and other performance hiccups. Check out this expert tip to learn what needs to happen to push 40 GbE into prime time.

Network performance testing considerations for a 40 GbE upgrade

Many existing network performance testing products don’t sufficiently handle the increased traffic and data of 40 GbE. If you upgrade from 10 GbE to 40 GbE but neglect to adopt newer network performance testing, you could end up with undetected problems in your network, negating the very benefits you expected from upgrading to 40 GbE in the first place. Read this tip to learn how to perform proper network performance testing.
