Correct Answer: Dynamic Provisioning (Option C)
Key Points:

  • Thin Provisioning

      Allocates storage only when data is written.
      Saves storage space.
      Lower performance due to metadata updates and fragmentation.

  • Pre-allocated (Thick) Provisioning

      Reserves all disk space immediately.
      Delivers the highest and most predictable performance.
      Consumes the full storage capacity from the start.

  • Dynamic Provisioning

      Combines the benefits of both approaches.
      Uses pre-allocated block structures while still allocating space based on demand.
      Achieves about 90% of thick disk performance while maintaining storage efficiency and overcommit capability.
      Requires a minimum 3-node cluster.

Additional Notes:

  • Supports space reclamation when using Virtio drivers and appropriate storage settings.

  • Suitable for most workloads because it balances performance and storage utilization.

  • For critical database workloads, pre-allocated disks are still recommended.

  • Administrators must monitor storage pools carefully because over-provisioning can lead to storage exhaustion.

Best Practice Recommendation:

  • Use Dynamic Provisioning for general-purpose virtual machines.

  • Use Pre-allocated Disks for high-performance databases and latency-sensitive applications.

  • Monitor storage usage and implement quotas to prevent storage overconsumption.

Main takeaway: Dynamic Provisioning is Sangfor HCI's recommended middle ground, offering near-thick-disk performance while preserving the storage efficiency of thin provisioning.
