One of the central tenets for Data Center 3.0 is the migration from GbE to 10GbE. Whether its to support unified fabric (FCoE or iSCSI) or to support the type of I/O consumption server virtualization is driving, we feel 10GbE is a fundamental building block of the next generation of data centers.
To that end, we have spent a good deal of effort providing our customers a granular and cost effective path from their current GbE infrastructure to 10GbE. We support fibre based connections across our switching portfolio with a wide variety of optics. With the advent of the Nexus 5000, we also added twin-ax to the mix with significantly lowered costs. A little while later, we introduced the Nexus 2000 fabric extenders at yet another option for customer migrating their data centers to 10GbE that both lowered costs and simplified management. We also recently added the Cisco Nexus 4000 blade switch for the IBM BladeCenter to the mix. The latest option we are offering is 10GBase-T (IEEE 802.3an-2006) support which allows customers to take advantage of their existing copper cabling as they navigate the transition to 10GbE. In keeping with the extend-your-investment theme, 10GBase-T will initially be available for the Cisco Catalyst family first, then the Cisco Nexus family.
With the addition of the 10GBase-T options, we continue to offer the broadest, most flexible portfolio of 10GbE options. Here are some more details:
