Through Cost Barriers
QLogic QLE3442-RJ 10GBASE-T adapters support the
higher bandwidth needed for virtual environments while
providing investment protection via backward compatibility
with 1GbE networks.
ABSTRACT
Deploying server virtualization in today’s data centers drives data
demand that challenges traditional 1 Gb/s throughput capabilities.
These consolidated virtual servers are typically configured with
multiple 1Gb/s ports in order to keep up with I/O demands. Deploying
a 10Gb/s network eliminates these 1 Gb/s bandwidth bottlenecks,
while dramatically simplifying cabling and management requirements
and reducing power and cooling demands. 10GBASE-T over common
CAT6a unshielded twisted pair (UTP)—priced less than optical media
solutions—enables rapid, large-scale adoption of 10GbE throughout
the data center.

10GbE SOLUTION
With new servers, users are able to increase the number of virtualized
servers (and therefore, the number of applications) running on a single
server, which leads to a significantly increased demand for I/O. This
accelerated adoption of server virtualization and convergence technologies
supports multiple workloads to consolidate physical servers, which
often increases the I/O demands well beyond the capabilities of 1 Gb/s
Ethernet ports.

Migrating to 10GbE fully addresses this I/O bandwidth bottleneck issue.
In recent years, data center managers have started migrating portions of
their data center to 10GbE networks using a combination of Direct Attach
Copper (DAC) cables for short distances (up to 7 meters for Top-of-Rack
connections) and fiber-optic cabling for longer distances (for End-of-Row
connections). The connectivity from the 10GbE port on the server often
involves a Top-of-Rack switch used to aggregate the DAC connectivity to
the servers, with fiber-optic connectivity to the End-of-Row switch.

This deployment of 10GbE—using SFP+ connections to accommodate
either fiber optics or DAC connectivity—improved the I/O capabilities for
virtualized servers, but the costs associated with a Top-of-Rack switch and
expensive cabling and optics limited the widespread adoption, especially
in data centers where 1GbE is already broadly deployed.
