Juniper Networks started shipping the EX8216 on May 1, 2009, one quarter after the launch of the EX8208. Releasing two such large-scale projects back-to-back would not have been possible without the extraordinary dedication of our engineering team, and I’d like to take a moment to recognize their accomplishments. Doubling the EX8208’s density was not a trivial exercise; everything from the ASICs to power and cooling needed to be planned in advance, while systems and software had to be designed, built and tested in parallel. One advantage of this approach was that any issue found on one platform could be fixed on the other at the same time, and the EX8208 backplane and EX8216 midplane could provide identical interfaces to the EX8200 line cards. As a result, when we first powered up the EX8216 early last year, it just worked.
The EX8216 is one of the most compact, full-featured chassis-based switches on the market. Its 128 wire-rate 10GbE ports allow it to consolidate or aggregate data centers with up to 4,000-6,000 servers into a single redundant pair of chassis with only 4:1 oversubscription from an access layer composed of EX4200 Virtual Chassis switches. This solution provides substantial cost and scale advantages over competitive architectures, making it ideal for large enterprise and service provider data centers and cloud computing applications. The combination of nearly two billion packets per second processing and a worst-case power envelope of under 10kW make the EX8216 ideal for internet peering sites and exchange points.
JUNOS Software supports a total solution--from server access port to WAN edge, including all security in between--reducing operational expenses with a single operating system running the EX4200 and EX8200 switches, M and MX series routers, and SRX security devices.
Just as significant is that the EX8216 provides the capacity to support future performance upgrades. The electrical characteristics of the EX8216’s unique orthogonal connector technology have been designed for the highest possible signaling rates. This design allows internal data traffic to transit directly from each line card to each switch fabric module, bypassing the mid-plane, and ensuring that customers who select the EX8216 will be supported through multiple generations of advances in ASIC technology. The EX8200 platform is designed for both the 1GbE and 10GbE networks of today as well as the 100GbE networks of tomorrow.
