This section brings together everything you need to connect Debian and Ubuntu hosts to Everpure FlashArray, covering quick start guides and best practices for iSCSI, NVMe-TCP, NFS, and Fibre Channel.
Why Debian and Ubuntu
Debian and its downstream distribution Ubuntu are among the most widely deployed Linux platforms in the enterprise, valued for their stability, extensive package ecosystem, and predictable long-term support cycles. Ubuntu LTS releases in particular are a common choice for production virtualization hosts, database servers, and container platforms, making reliable, well-documented storage connectivity essential.
Why FlashArray
FlashArray gives Debian and Ubuntu hosts a consistent, high-performance storage foundation regardless of which transport you choose. It supports both traditional SAN protocols, File protocols and modern NVMe-based transports, so hosts can connect over Fibre Channel, iSCSI, NFS or NVMe-oF while using the same simple model for creating volumes or file systems, connecting hosts, and managing access. This flexibility lets you align storage connectivity with your network design and performance goals, and provides a clear modernization path from SCSI-based transports to NVMe as your environment evolves.
Key benefits of running Debian/Ubuntu on FlashArray include:
Low-latency, high-performance block storage for business-critical workloads such as databases and virtualized infrastructure.
Multiple connectivity options on one platform — iSCSI, NVMe-TCP, NVMe-FC, NFS, and Fibre Channel can all run on the same array, so Debian/Ubuntu hosts can adopt the transport that best fits available networking hardware.
NVMe-TCP performance gains over iSCSI — up to 35% higher IOPS, 25% lower latency, and 20% better throughput, using only standard Ethernet NICs and switches, with no specialized hardware required.
Resilient file access for NFS workloads — recommended mount options such as NFSv4.1 and nconnect maintain application-transparent I/O continuity through FlashArray controller failover.
Integration with core FlashArray data services, including snapshots, replication, and host-based workflows, across every supported protocol.
What's Inside
The pages that follow provide distribution-specific, task-oriented guidance for Debian and Ubuntu. Each quick start guide focuses on getting a host connected and validated quickly, while the accompanying best practices guide covers production-hardening topics such as network design, security, high availability, and ongoing monitoring.
