Integrate the OS You Need

From NAS Appliances to Scale-Out Systems

We support leading NAS and scale-out storage OS options and provide full integration
services for customized environments.

Two Integration Approaches

We differentiate between operating systems we can install directly on hardware versus those requiring additional
hardware layers for optimal performance.

Direct Installation

OSs we can install directly on validated hardware

• TrueNAS
• Ubuntu
• Red Hat / CentOS
• Proxmox + ZFS
• Open source NAS platforms

Hardware Layer Integration

Platform requiring additional hardware abstraction

• Synology
• QNAP
• VMware
• Proprietary appliance OS
• Vendor-locked platforms

Supported Operating Systems

We provide full support for operating systems we install and manage directly on validated
hardware — no extra layers or proprietary appliances needed.
