SAA-C03 Q421 · Migration

Question

A company runs an HPC workload that uses a 200-TB file system on premises. The company needs to migrate this data to Amazon FSx for Lustre. Internet capacity is 10 Mbps, and all data must be migrated within 30 days. Which solution will meet this requirement?

Accepted Answer

**Answer D: AWS Snowball Edge → S3 → FSx for Lustre**

**Step 1: Calculate if network transfer is feasible.**
- 10 Mbps = ~1.25 MB/s = ~108 GB/day = ~3.24 TB in 30 days
- 200 TB of data **cannot** be transferred over a 10 Mbps link in 30 days. You'd need approximately **1,852 days** (~5 years).
- This immediately eliminates any solution that relies solely on network-based transfer.

**Step 2: Why Snowball Edge?**
- A single Snowball Edge Storage Optimized device holds ~80 TB usable capacity.
- You'd need approximately 3 devices to move 200 TB.
- Physical shipping + data loading typically takes 1-2 weeks, well within the 30-day window.
- Data is loaded onto the devices on-premises, shipped to AWS, and ingested into Amazon S3.

**Step 3: How FSx for Lustre links to S3.**
- FSx for Lustre nat
