The Linux host connectivity documentation helps you configure Linux and related host environments for storage access with FlashArray. It combines setup instructions, transport-specific guidance, and operational recommendations so you can choose the connectivity method that best fits your infrastructure and deployment requirements.
It includes the following:
-
SCSI host configuration
Covers commonly used Linux block storage configuration for SCSI-based connectivity. This includes the core host-side setup and validation steps needed to prepare Linux environments for storage access before layering on protocol-specific guidance.
-
iSCSI host configuration
Explains how to prepare Linux hosts for block storage connectivity by installing the required initiator and multipath packages, identifying the host initiator, discovering storage targets, logging in to sessions, and verifying connectivity. It also includes guidance for configuringLinux hosts for iSCSI with FlashArray including optional interface configuration for multipath or multi-NIC environments.
-
NVMe host configuration
Covers foundational host requirements such as loading the appropriate kernel modules, understanding supported multipath models, choosing between available NVMeconnection methods, and validating that connected paths and devices are visible as expected. It also includes transport-specific guidance for NVMe/TCP, NVMe/RoCE, and NVMe/FC deployments, including setup, validation, and operational considerations such as performance, firmware, adapter, and network requirements where applicable.
-
Multipathing guidance
Explains how to improve resilience and performance through multiple storage paths. It includes device-mapper multipath, native NVMe/multipath considerations, and broader recommendations to help determine the appropriate model for each Linux distribution and transport type.
-
NFS host configuration
Explains how to configure Linux hosts for file-based storage access, including client-side services, connectivity validation, firewall considerations, recommended mount options, and production guidance for redundancy, performance tuning, SELinux considerations, and troubleshooting.
-
Quick start guides for Linux distributions
Covers common storage protocols such as iSCSI, NVMe//TCP, and NFS across major Linux distributions including RHEL, Rocky Linux, AlmaLinux, Debian, Ubuntu, SUSE, and openSUSE. These guides focus on initial setup and help with package installation, service enablement, network configuration, and validation.
-
Advanced deployment topics
Includes additional reference material for scenarios such as multipath boot from SAN on SUSE 12, helping you support persistent boot-time storage access while maintaining the benefits of multipath configuration.
Overall, these topics help you understand available Linux host connectivity options, prepare hosts correctly, and follow the appropriate setup path for your protocol, operating system, and deployment model.
