Aviz Networks outlines SONiC options for 40% 400GbE TCO savings

The blog says pairing 400GbE switches with SONiC as the network operating system can cut total cost of ownership by about 40% versus conventional vendor NOS, while giving customers control of the NOS layer. For enterprise IT and security leaders, the update frames how network operating choices affect budgeting for next-generation switching.

Research Overview

The post links an ongoing shift to 400GbE to broader market growth for 200/400GbE switching, referencing an IDC report. It also centers SONiC as the approach for owning the NOS layer when adopting 400GbE switching.

The blog frames TCO as a recurring challenge in 400GbE planning and proposes that SONiC adoption is a factor in reducing costs. It describes the vendor’s intent as enabling 400GbE adoption while commoditizing networking infrastructure over time.

Key Findings

The blog provides pricing-based comparisons that it says result in 40% savings. It states that using approximately 500 switches with a leading vendor and conventional NOS could cost between $25,000 and $35,000 per 400GbE switch, while SONiC NOS with the same ASICs could cost between $12,000 and $16,000 per 400GbE switch.

The post cautions that pricing can vary by customer buying power, but it says the purchasing advantage applies to SONiC solutions for the hardware chosen. It states that TCO savings remain around 40% or more based on the figures cited.

Technical Breakdown

The blog describes SONiC as taking ownership of the NOS layer for 400GbE networks. It connects that approach to “control,” and it describes SONiC as part of how enterprises can run 400GbE with an owned software layer.

It also mentions SONiC “recipes” associated with easy rollout and states that these recipes support consuming 400GbE networks while using the claimed TCO savings. The post ties this to adoption planning for enterprises deploying at scale.

Operational Impact

The post says executive goals align with the proposed approach: adopting 400GbE, owning the NOS for greater control and future-proofing, and achieving TCO that reduces costs. It presents these goals as outcomes tied to adopting SONiC with 400GbE switching.

It provides an example of early adopters and points to an eBay deployment write-up about cost savings and bandwidth using white-box switches running SONiC. The blog uses this as an illustration of operational rollout rather than a general performance claim.

Leadership Perspective

The post frames infrastructure planning discussions around what enterprises consider when they choose infrastructure, describing three recurring priorities from “Global 1000” customers. Those priorities are described as staying current with technology, making future-proof choices, and saving on TCO by leveraging commodity approaches.

It also states that Aviz has developed deployment recipes for 400GbE consumption and says it offers options described as “100+ SKU choices.” The post states that the approach is “Normalized Community SONiC,” with the customer in control of the NOS layer.

Overall, the blog centers on 400GbE adoption with SONiC for the NOS layer and argues that this pairing can reduce TCO by about 40% using cited switch-level cost ranges and an eBay deployment example. It presents these points as relevant to enterprise decision-makers evaluating next-generation switching and NOS ownership, and this “Blog Signals brief” is a fact-based summary of the vendor blog.
