Microsoft Azure Qualifies Seagate’s High-Capacity Storage Setup for AI Data Centers

Seagate today announced that it has reached a major storage milestone with Microsoft Azure, as AI workloads continue driving demand for data center capacity. The company’s Mozaic drives have cleared another interoperability hurdle, making high-capacity storage easier to integrate into large-scale infrastructure.

Azure validates Seagate and Broadcom’s storage configuration

In an official press release. Seagate noted that its Mozaic drives are the first and only shingled magnetic recording (SMR) drives added to Broadcom’s approved vendor list for its host bus adapter (HBA). The component connects servers with storage devices, helping data centers manage large hard drive fleets.

Microsoft Azure Storage has also completed qualification of Broadcom’s HBA with Seagate’s heat-assisted magnetic recording (HAMR) and SMR technology. This provides a hyperscale validation point for the combined configuration.

The announcement comes as cloud providers expand infrastructure to support increasingly demanding AI workloads. Not to forget, Microsoft is also expanding its Azure infrastructure to meet growing AI demands, including through its partnership with AMD on next-generation AI infrastructure.

Seagate targets growing demand for high-density storage

Seagate says combining its storage technology with Broadcom’s connectivity infrastructure should make high-capacity SMR drives easier to deploy. The configuration could help operators connect and manage larger drive fleets as their data requirements grow.

HAMR enables Seagate to increase storage density, while SMR overlaps data tracks to provide additional usable capacity for suitable workloads. Together, the technologies target data-intensive environments where capacity and infrastructure efficiency matter.

The development also follows rising pressure on the storage supply chain. Early this year, Seagate and Western Digital have previously faced strong demand from AI data centers, with much of their high-capacity hard drive production reportedly booked.

More storage capacity without changing the whole infrastructure

Microsoft says its joint qualification demonstrates how Seagate and Broadcom’s technologies can work together across large data center deployments. The company expects the configuration to enable greater storage density within a similar cost and power envelope.

The announcement does not include specific deployment volumes or a rollout timeline. Still, Azure’s qualification provides an important compatibility milestone for organizations planning high-capacity storage at hyperscale. Microsoft has also pursued infrastructure efficiency through technologies such as Azure Boost, which targets faster data movement and lower power consumption for cloud workloads.
