AWS® Marketplace deployment summary

Product: Roadrunner SMB™
Category: SMB3 gateway for Amazon EFS®
Deployment model: AWS Marketplace CloudFormation® deployment into your VPC

Capacity and availability

• Node count: Configurable 1–8 nodes at deploy time (ClusterSize) and after deploy via Admin UI Cluster page. 9–16 is Experimental (beta).
• Eval Kit: Self-contained evaluation only (default 2 nodes).
• Dual-AZ: Only supported production path. 4-node reference architecture recommended.

Launch and stacks

• Launch form: Eval Kit (kit-created VPC) or Dual-AZ (VPC ID + cluster node count).
• Two stacks: a parent stack (RoadrunnerSMB-Eval / RoadrunnerSMB-DualAZ) and a nested appliance stack (…-InnerStack-…). Subnets and image are auto-configured on the nested stack.
• Cluster ID: fixed rrsmb-prod for DynamoDB® tables and cluster state (not the stack name). One appliance per AWS Region is supported today.
• Find URLs: CloudFormation → parent stack → Outputs → AFirstTimeSetupInstructions (one-click setup) or AdminUIUrl.

Access and integration

• Admin UI: AdminUIUrl on the parent stack Outputs. Eval Kit uses CloudFront + WAF (internet). Dual-AZ uses private ALB + WAF (VPN / DX / jump box). Port 8888 is an internal target port on tasks.
• SMB: TCP / port 445 using NlbDnsName from networks in SmbClientCidr (default VPC/private client ranges — not the public internet by default).
• Authentication: Active Directory® integration (domain join, Kerberos/NTLM). Plan join and admin identities: Identity and permissions.
• Storage backend: Amazon EFS (shared file data and cluster coordination paths as provisioned by the stack).

Clustering and routing

• CTDB: Provides clustered Samba state coordination across nodes. Customer-facing routing, health-based traffic steering, and node failover are handled by AWS load balancing, ECS health checks, and Roadrunner SMB readiness/fencing — not customer-facing CTDB “floating IP” failover.

Updates

• Roadrunner SMB discovers newer approved releases via the product release manifest and Marketplace release ECR repository (stable channel). When automatic updates are enabled, a newly detected release is scheduled for the next local midnight after detection (Region-local timezone of the deployed AWS Region). Use Apply latest approved version on the Admin UI Software Update page to update immediately, or Defer to postpone by 24 hours. Rolling replacement preserves availability on multi-node deployments.
• Change control: Review release notes before allowing production updates when your organization requires it.

Support

• Support report: Generate and download a Support Report from the Admin UI and attach it to your support request (reports are not uploaded automatically).
