X460-G2 series the scalable advanced aggregation and edge switch with the revolutionary Extreme XOS modular operating system. The X460-G2 series is based on Extreme Networks revolutionary Extreme XOS, a highly resilient OS that provides continuous uptime, manageability, and operational efficiency. Each switch offers the same high-performance, non-blocking hardware technology, in the Extreme Networks tradition of simplifying network deployments through the use of common hardware and software throughout the network. The X460-G2 switches are effective campus-edge switches with IEEE 802. 3at Po E-plus and can also serve as aggregation switches for traditional enterprise networks. The X460-G2 series is also an option for DSLAM or CMTS aggregation, or for active Ethernet access. The X460-G2 can also be used as a top-of-rack switch for many data center environments with features such as high-density Gigabit Ethernet for concentrated data center environments; XNV (Extreme XOS Network Virtualization) for centralized network-based Virtual Machine (VM) inventory, VM location history, and VM provisioning; Direct Attach to offload VM switching from servers, thereby improving performance; high-capacity Layer 2/Layer 3 scalability for highly virtualized data centers; and intra-rack and cross-rack stacking with industry-leading flexibility.
