The BlackDiamond 6804: One Small Switch from Extreme,

One Big Boost for IT Pros

TECH BRIEF

Bigger is better? Just try telling that to an IT manager attempting to cram another piece of gear into an overcrowded wiring closet.

At that point, small isn’t just beautiful, it’s also smarter.

Extreme Networks® has something much more effective than a shoehorn or a sledgehammer for the spatially challenged.

Introducing the four-slot BlackDiamond® 6804, the newest—and smallest—member of Extreme’s family of highly resilient

Ethernet switches.

Don’t confuse proportions with performance: The only thing undersized about the 6804 is its form-factor. Like its bigger brothers,

it delivers wire-speed performance; scales seamlessly from 10 Mbps to 10 Gbps; offers a wealth of interface options; provides

the industry’s most sophisticated Policy-Based Quality of Service (QoS); is engineered for maximum redundancy and reliability;

and furnishes air tight security—including Network Login, Extreme’s pioneering authentication scheme. In fact, given its abilities,

the 6804 doesn’t have to be restricted to the wiring closest. It’s equally at home in small data centers, on the edge of midsized

enterprise networks, at remote ofﬁces and in R&D labs, where space is typically in short supply. It also can be used to aggregate

trafﬁc when oversubscription ratios aren’t excessively high.

Actually, there is one difference between the 6804 and its bulkier brethren: the price of entry. Other than that, it’s pure

BlackDiamond. And that’s very good news for Extreme customers who’ve already deployed 6808s or 6816s. Since all

BlackDiamonds accept the same blades, management switch fabric modules (MSMs), power supplies, and gigabit interface

connectors (GBICs), that can add up to some serious savings thanks to recycling (sparing). And with one switch series in place, IT

managers don’t have to maintain separate inventories—another savings in investment and resources. What’s more, the 6804

runs the same ExtremeWare® software and uses the same Infrastructure & Ser vices Management software suite found on all

Extreme switches, thus ensuring consistent services and management across the enterprise. It’s also built around the “i”-series

chipset that powers virtually ever y Extreme product.

This sort of end-to-end thinking is nothing new for Extreme. Like its enterprise customers, Extreme understands that applications

and services are no better than the networks they run on. By giving IT managers some common, easy-to-use management tools

and utilities, Extreme frees them to concentrate on their real tasks: supporting and developing corporate apps. Further, by

ensuring that BlackDiamond components are truly interchangeable, Extreme makes certain that enterprise networkers get the

most bang for their budget.

There’s another reason to go with a BlackDiamond: As the core of the Extreme product line, these switches are always ﬁrst in line

for the most advanced modules—like 10 Gigabit Ethernet.

Meet the Family

The BlackDiamond product line comprises three modular chassis. At 11 rack units, the 6804 features four slots for I/O modules,

two for MSM, and two bays for load-sharing power supplies. Slotting in redundant supplies and management modules boosts

switch reliability. Further, the power supplies and MSMs are hot swappable; they can be replaced in a matter of minutes while the

6804 keeps working. The 6804 also features a passive nonblocking 64 Gbps backplane; since there are no active components,

there’s nothing to fail—increasing reliability even further. Fully equipped, the 6804 delivers 384 10/100 Mbps ports or 32

Gigabit Ethernet por ts or four 10 gig ports and can process 48 million packets per second.

At 15 rack units, the 6808 furnishes eight slots for switching modules, along with two for MSMs and two bays for redundant

power supplies. Its 128 Gbps passive nonblocking backplane—and its ability to accommodate 672 10/100 Mbps ports, 64

Gigabit Ethernet por ts, or eight 10 gig ports—make it ideal for heavy-duty aggregation. That enables enterprise networkers to deal

effectively and cost-efﬁciently with oversubscription, which can easily reach ratios of 20-to-1, 30-to-1 or higher. And the fact that

the 6808 churns through 96 million packets per second also explains why many companies deploy it in their data centers.
