Microsoft’s Project Natick underwater data center experiment confirms viability of seafloor data storage

Published September 14, 2020

Microsoft has concluded a years-long experiment involving use of a shipping container-sized underwater data center, placed on the sea floor off the cost of Scotland’s Orkney Islands. The company pulled its “Project Natick” underwater data warehouse up out of the water earlier this year (at the beginning of the summer) and spent the last few months studying the data center, and the air it contained, to determine the model’s viability.

The results not only showed that using these offshore submerged data centers seems to work well in terms of performance, but also revealed that the servers contained within the data center proved to be up to eight times more reliable than their dry-land counterparts. Researchers will be looking into exactly what was responsible for this greater reliability rate in the hopes of also translating those advantages to land-based server farms for increased performance and efficiency across the board.

Other advantages included being able to operate with greater power efficiency, especially in regions where the grid on land is not considered reliable enough for sustained operation. That’s due in part to the decreased need for artificial cooling for the servers located within the data farm because of the conditions at the sea floor. The Orkney Island area is covered by a 100% renewable grid supplied by both wind and solar, and while variances in the availability of both power sources would’ve proven a challenge for the infrastructure power requirements of a traditional, overland data center in the same region, the grid was more than sufficient for the same size operation underwater.

Microsoft’s Natick experiment was meant to show that portable, flexible data center deployments in coastal areas around the world could prove a modular way to scale up data center needs while keeping energy and operation costs low, all while providing smaller data centers closer to where customers need them, instead of routing everything to centralized hubs. So far, the project seems to have done spectacularly well at showing that. Next, the company will look into seeing how it can scale up the size and performance of these data centers by linking more than one together to combine their capabilities.

Microsoft Azure now lets you have a server all to yourself

Published August 1, 2019

Microsoft today announced the preview launch of Azure Dedicated Host, a new cloud service that will allow you to run your virtual machines on single-tenant physical services. That means you’re not sharing any resources on that server with anybody else and you’ll get full control over everything that’s running on that machine.

Previously, Azure already offered isolated Virtual Machine sizes for two very large virtual machine types. Those are still available, but their use cases are comparably limited to these new hosts, which offer far more flexibility.

With this move, Microsoft is following in the footsteps of AWS, which also offers Dedicated Hosts with very similar capabilities. Google Cloud, too, offers what it calls “sole-tenant nodes.”

Azure Dedicated Host will support Windows, Linux and SQL Server virtual machines and pricing is per host, independent of the number of virtual machines you end up running on them. You can currently opt for machines with up to 48 physical cores and prices start at $4.039 per hour.

To do this, Microsoft is offering two different processors to power these machines. Type 1 is based on the 2.3 GHz Intel Xeon E5-2673 v4 with up to 3.5 gigahertz of clock speed, while Type 2 features the Intel Xeon® Platinum 8168 with single-core clock speeds of up to 3.7 gigahertz. The available memory ranges from 144GiB to 448GiB. You can find more details here.

As Microsoft notes, these new dedicated hosts can help companies reach their compliance requirements for physical security, data integrity and monitoring. The dedicated hosts still share the same underlying infrastructure as any other host in the Azure data centers, but users have full control over any maintenance window that could impact their servers.

These dedicated hosts can also be grouped into larger host groups in a given Azure region, allowing you to build clusters of your own physical servers inside the Azure data center. Because you’re actually renting a physical machine, any hardware issue on that machine will impact the virtual machines you are running on them, so chances are you’ll want to have multiple dedicated hosts for your failover strategy anyway.
