Sovereign data center with a Tier III design in the heart of Marseille: 1,700 m² of colocation space, 1.2 MW of power and a PUE of 1.2, within the world's 6th largest interconnection hub.
DC-M1 combines international connectivity, high density and 24/7 local operations.
DC-M1 combines infrastructure under French control, a rehabilitated existing building in the heart of Marseille and a design built for high-density IT loads.
DC-M1 is operated by a company incorporated under French law, with European shareholders and a preference for European suppliers.
Your equipment and the data it hosts remain in France, under French jurisdiction. Phocea DC's financial and legal independence shields them from extraterritorial legislation, including the Cloud Act and FISA.
DC-M1 is located in a fully rehabilitated existing building in the heart of the 3rd arrondissement, with no new land take and no additional soil sealing.
Its operations teams are on site 24/7 to work directly on our customers' infrastructure.
DC-M1 is designed to host high-density infrastructure, particularly HPC and AI environments, with several cooling technologies suited to compute requirements, including free cooling, Direct Liquid Cooling and Immersion Cooling.
From a single rack to a private suite, DC-M1 lets you adapt space, power
and interconnection options to your configuration.
DC-M1 is designed to Tier III principles, with a redundant architecture that allows critical components to be maintained without any planned interruption to IT equipment.
Uses outside air whenever conditions allow, reducing reliance on mechanical cooling.
A cold plate in direct contact with the CPU and GPU removes heat right at the component level. A solution suited to AI clusters and high-density compute environments.
Equipment is immersed in a dielectric fluid that removes heat efficiently. This technology enables high compute density, with no fans and silent operation.
Marseille is the world's 6th largest interconnection hub, with 18 subsea cables and direct access to the major international digital routes.
Located at this point of convergence and connected to terrestrial networks running to northern Europe, DC-M1 holds a strategic position between Mediterranean and continental networks.
As a carrier-neutral facility, Phocea DC lets you freely choose your carriers, transit providers and peering points.
Cross-connects, metro connects and network interconnections let you build architectures tailored to your performance and resilience requirements.
Security at DC-M1, our first site, relies on several layers of protection: access control, continuous monitoring, fire detection and equipment protection, with local 24/7 operations.
Phocea DC's certifications let you rely on recognized standards to meet your own security, continuity and compliance requirements.

Located in the La Villette district, DC-M1 offers an urban location that is easy to reach for your teams and contractors.
24/7 site access for authorized operations.
The development of DC-M2 and then DC-M3 will gradually expand Phocea DC's capacity in Marseille and support growing needs in colocation, connectivity, cloud, CDN, AI and HPC.
Yes. Our data centers are designed to be genuinely carrier-neutral.
Phocea DC does not favor any telecom carrier: our customers are free to choose their connectivity providers based on their needs, technical constraints and costs.
Located at the heart of Marseille's digital ecosystem, DC-M1 offers access to a wide choice of carriers and networks. This neutrality also makes it possible to build multi-carrier architectures and secure the interconnections of your infrastructure.
Your infrastructure, your carrier, your choice.
Yes. Phocea DC can host infrastructure that processes health data.
DC-M1 holds scope 1 of the Health Data Hosting (HDS) certification, allowing it to host health infrastructure and data in an environment that meets the applicable regulatory and security requirements.
Our environment also benefits from certifications and security measures suited to organizations with demanding requirements for availability, confidentiality and business continuity.
Whether you are a healthcare provider, a software vendor, a digital health company or an IT service provider, Phocea DC supports you in deploying your infrastructure in a sovereign, secure environment.
Our data centers are designed to host high-density infrastructure.
Racks can be configured for different power levels, up to environments that require high compute density. This makes it possible to support AI, GPU and HPC infrastructure as well as traditional production architectures.
Phocea DC assesses each project based on the required IT power, equipment configuration and cooling constraints in order to propose a suitable solution.
From standard racks to high-density infrastructure, power scales to your project.
Yes, and we actually recommend it.
A visit gives you a first-hand look at our infrastructure, security systems, technical areas and connectivity environment.
It is also an opportunity to talk directly with our teams about your project, your technical constraints and your power, availability and connectivity needs.
Because choosing a data center is a strategic decision, we prioritize transparency and close contact from the very first discussions.
The commissioning lead time depends on your project and the resources to be deployed.
Once your requirements are validated, our teams work with you to define the configuration of your environment: power, number of racks, connectivity and any specific needs.
We then schedule the handover of your infrastructure so you can deploy as quickly as possible, while ensuring our technical and security requirements are met.
Simple project or complex infrastructure: we build a realistic deployment schedule with you from the scoping phase.
In the event of a grid power outage, continuity of power to your infrastructure is ensured by the data center's backup systems.
Our data centers are designed to keep IT equipment powered in the event of a grid failure, thanks to a redundant electrical architecture that combines UPS systems and diesel generators.
The goal is simple: a public grid outage must not bring your infrastructure down.
Backup systems are designed and tested to take over automatically and keep operations running until normal power is restored.
