President and Chief Executive Officer at Broadcom
Thank you, Ji, and thank you, everyone, for joining us today. In Q3, semiconductor solutions revenue grew 19% year-on-year to $5 billion, with infrastructure software revenue growing 10% year-on-year to $1.8 billion, consolidated net revenue was $6.8 billion or up 16% year-on-year. In Q3, demand continued to be strong from hyper cloud and service provider customers. Wireless continuing to have a strong year-on-year compare and wireline enterprise has been on a trajectory of recovery, we believe Q3 is still early in that cycle and that enterprise was down year-on-year. On the supply side, we continue to keep our lead times stable.
With that as context, let me provide more color by end markets. Starting with networking. Networking revenue of $1.8 billion grew stronger than we had forecasted, up 19% year-on-year versus low-double-digit growth and represented 36% of our semiconductor revenue. The better-than-expected growth was driven by routing from service providers in the expansion of 5G networks for backhaul, metro and core, as well as major share gains in Ethernet network interface controllers within data centers. While we experienced strong orders from OEMs, consistent with a recovering environment for enterprise spending, we believe actual deployment of networking and enterprise are still lagging from a year ago. Our shipments and revenue appropriately reflects this.
In Q4, however, we expect a different set of demand dynamics. We see cloud customers upgrading to our next-generation 800 gigabit BASE Tomahawk 4 and Trident switches. We're the first and only provider of 25.6 terabit switches and we are shipping two versions: one with 512 lanes at 50G SerDes; and the other 256 lanes at 100G SerDes. I would like to highlight that we are the only Company today shipping 100G SerDes. In data center switching, as in service provider routing, we're continuing to lead in next-generation product transitions as our engineers continue to out -- execute what's out there. And in Q4, against a very strong year-on-year compare, we expect networking revenue growth to be low-double digits year-on-year.
Next, our server storage connectivity business was $673 million in Q3, down 9% year-on-year, in line with our guidance and represented approximately 13% of semiconductor revenue. As you know, our products here supply mission-critical applications largely to enterprise, which as I said earlier, was in a state of recovery. That being said, we have seen a very strong bookings trajectory from traditional enterprise customers within this segment. We expect such enterprise recovery in server storage and the same is happening in networking to be one of the engines of growth in Q4 and into 2022. In this particular segment, customer transition to our next-generation SAS and NVMe connectivity at the server is amplifying [Phonetic] this growth. The aggressive migration in cloud to 18 terabyte hard disk drives will also provide a strong tailwind to demand for external storage connectivity products in this segment. In sharp contrast to the 9% decline in Q3, we forecast in Q4, server storage connectivity revenue to be up low-double digits percentage year-on-year.
Moving onto broadband, revenue of $910 million in Q3 grew 23% year-on-year and represented 18% of semiconductor revenue. This was primarily driven by the 2x growth in deployments of Wi-Fi 6 access gateways, as well as double-digit growth in next-generation fiber and DOCSIS 3.1 cable modem deployments. For Q4, we continue to expect double-digit year-on-year revenue growth in broadband that we have been seeing for the last few quarters. So looking ahead, we see service providers like AT&T, British Telecom and even Deutsche Telekom deploying an increasing volumes next-generation last mile fiber connectivity to homes in the US and globally. These are multi-year and multi-billion dollar investments by these operators. And attached to every one of this fiber notes, you need Wi-Fi connectivity for the last 100 feet within the homes. And we lead the global transition to Wi-Fi 6 to date. We expect our strong design win momentum for Wi-Fi 6E at US and European operators will sustain our market position into the next-generation.
Now, moving to wireless. Q3 revenue of $1.4 billion was up 35% year-on-year in line with expectations and represented 29% of semiconductor revenue mix. In Q4, we expect wireless revenue to ramp approximately 33% sequentially in support of the launch of next-generation smartphones and to be up 25% year-on-year.
Finally, industrial, revenue of $205 million in Q3 represented approximately 4% of Q3 semiconductor solutions revenue. Resales here grew what we consider an unsustainable 55% year-over-year, driven by aggressive buying from OEMs in automotive, robotics and renewable energy. As a result, inventory in our channels declined significantly to below two months. And turning to Q4, we do expect resales to come down to a more rational 20% year-upon-year growth.
And so, in summary, Q3 semiconductor solutions revenue was up 19% year-on-year, and in Q4, we expect the momentum to continue and revenue growth to be up double digits percentage year-on-year.
Turning to software. In Q3, infrastructure software revenue of $1.8 billion, grew 10% year-on-year and represented 26% of total revenue. Within this, Brocade grew 27% year-on-year, driven by the launch of new generation Gen 7 fiber channel SAN products. Excluding Brocade, Broadcom software revenue grew 6% year-on-year. In dollar terms, bookings average 116% over expiring contracts, while in the call -- while in our call accounts, we average 129%. Over 9% of these bookings represented recurring subscription and maintenance revenues. Reflecting these renewals, we expect our infrastructure software revenue to be on track to grow around mid-single-digit percentage year-over-year, which is again what we expect to see in Q4.
So in summary, combining a strongly growing semiconductor segment with a more stable software segment, total Q3 net revenue grew 16% year-on-year, and we expect this double-digit growth to sustain in Q4 and total revenue to be $7.35 billion or up 14% year-on-year.
And with that, let me turn the call to Kirsten.
