Product Overview

The Inventec D6254QS is a 1/10GbE SFP+ top of rack ideal for Datacenter server access well as Enterprise and Service Provider network deployments. It is capable of line-rate L2/ L3 switching performance in a compact 1RU form factor. The D6254QS switch offers an option of either a 2.4GHz x86 Quad-Core or 1.5GHz PPC Quad-Core CPU and supports a total of with 48 x 1GbE/10GbE SFP+ interfaces and 6 x 40GbE QSFP+ interfaces with a true PHY-less design. The D6254QS dramatically reduces energy consumption and power efficiency by placing lightly loaded ports into a low power state. It also supports server wake on LAN functionality.

Support for Open Network Ecosystems

The Inventec D6254QS supports multiple Network Operating Systems (NOS) including: Inventec IN-OS and Pica8® PicOS®. The Inventec D6254QS is also OpenFlow and SDN enabled. Full ONIE support assures network operators that the Inventec D6254QS seamlessly integrates into today’s open network environments.

Feature-Richness, Performance, and Port Density

The Inventec D6254QS offers low cut-through mode latency, 12MB on-chip packet buffer memory, and dynamic buffer management. Dedicated unicast and multicast queues provide separate scheduling structures with support for applications such as IEEE 802.1Q, VxLAN, L2GRE, and NVGRE. Overall feature-richness, high-availability, performance, port-density, and line-rate switching capability make the D6254QS an excellent choice for next generation large and medium sized datacenters. This also makes the D6254QS well suited for use as a general purpose aggregation switch in Enterprise and Service Provider networks.
