NVMe-TCP - SUSE-Specific Considerations

SLES vs openSUSE

SUSE Linux Enterprise Server (SLES):

• Enterprise-grade, commercial support

• Long-term support (10-13 years)

• Certified for enterprise workloads

• Requires active subscription

• Conservative package updates

• Recommended for production storage

openSUSE Leap:

• Community-supported

• Based on SLES codebase

• Free to use

• Shorter support cycle (18 months)

• Good for non-critical workloads

openSUSE Tumbleweed:

• Rolling release

• Latest packages

• Not recommended for production storage

• Good for testing/development

Recommended Versions

Production deployments:

• SLES: 15 SP3, SP4, or SP5

• openSUSE Leap: 15.3, 15.4, or 15.5

Kernel requirements:

• Minimum: Kernel 5.3 (SLES 15 SP2)

• Recommended: Kernel 5.14+ (SLES 15 SP4)

Check kernel version:

uname -r

# Verify NVMe-TCP module is available
modinfo nvme-tcp

Subscription Management (SLES)

Register system:

# Register with SUSE Customer Center
sudo SUSEConnect -r <REGISTRATION_CODE>

# List available extensions
sudo SUSEConnect --list-extensions

# Activate required modules
sudo SUSEConnect -p sle-module-server-applications/15.5/x86_64

# Update system
sudo zypper refresh
sudo zypper update -y

Check subscription status:

sudo SUSEConnect --status

# Core NVMe and multipath tools
sudo zypper install -y \
    nvme-cli \
