The Q1 server and storage component market grew 62% y-o-y, says Dell’Oro with surging demand for accelerators, HBM, and NICs underpinning record expansion across the AI infrastructure stack.
“The AI accelerator market was led by robust uptake of NVIDIA’s Blackwell GPU platform as well as the continued rollout of custom accelerators by major cloud service providers,” says Dell’Oro’s Baron Fung, “we estimate Blackwell has already surpassed an estimated 50 percent of the company’s high-end GPU shipments during the quarter, which in turn is prompting upgrades in networking, storage, and infrastructure across the data center.
“Meanwhile, custom silicon continues to gain traction with hyperscalers expanding their deployment of custom accelerators for both training and inference of large foundational models,” adds Fung, “beyond AI-specific hardware, general-purpose components such as CPUs, memory, storage drives, and NICs also saw meaningful growth in early 2025. This was partly driven by a recovery in mainstream enterprise server demand, as well as inventory builds and component price hikes ahead of the anticipated expiration of the 90-day reciprocal tariff pause.”
The Server and Storage Systems Component market is forecast to grow by over 50 percent in 2025 despite tariff-related uncertainties.
Hynix led the HBM market with a 64 percent revenue share, followed by Samsung and Micron.
ARM CPUs now hold 25 percent of the server market, driven by the NVIDIA GB200 Blackwell ramp and hyperscaler custom deployments.
Smart NIC and DPU revenues increased by 71 percent because of strong deployment of Ethernet adapters in AI clusters.
