IBM Storage Scale is a high-performance, software-defined storage solution designed to manage large volumes of data across distributed environments. It provides a unified global namespace, supports POSIX-compliant file systems, and enables seamless data access across hybrid cloud infrastructures.
When deployed in IBM Cloud, Storage Scale offers flexibility, scalability, and resilience for demanding workloads such as AI/ML, HPC, and big data analytics. It can be deployed on Virtual Server Instances (VSIs) or Bare Metal Servers in VPC. Choosing between the two depends on performance needs, scalability, cost, and operational complexity.
When to Choose IBM Cloud VSI
- Elasticity and Quick Provisioning
- Rapid provisioning and scaling for dynamic workloads or PoCs.
- Cost Optimization
- Lower upfront costs with pay-as-you-go pricing.
- Cloud-Native Integration
- Seamless integration with IBM Cloud services like Object Storage, Kubernetes, and Watson.
- Moderate I/O and Compute Workloads
- Suitable for small to medium AI/ML, analytics, or DevOps workloads.
- Simplified Management
- Easier automation and orchestration using IBM Cloud APIs and DevOps tools.
Advantages of Deploying Storage Scale in IBM Cloud VSI
- Elastic Scalability: Dynamically adjust cluster size based on workload.
- Rapid Provisioning: Quick setup for development and testing.
- Cost Efficiency: Ideal for variable workloads.
- Cloud-Native Integration: Connects easily with IBM Cloud services.
- Simplified Management: Streamlined operations via automation tools.
- Instance Storage Support: Use attached instance storage for temporary or scratch data, improving performance for short-lived or cache-heavy workloads.
When to Choose IBM Cloud Bare Metal
- High Performance and Low Latency
- Dedicated resources with no virtualization overhead.
- Maximum IOPS and Throughput
- Ideal for I/O-intensive workloads and parallel file access.
- Customization and Control
- Full control over OS, kernel, and hardware configuration.
- Stable, Long-Term Workloads
- Cost-effective for predictable, always-on environments.
- Large Cluster Deployments
- Supports high node counts and tightly coupled clusters.
Advantages of Deploying Storage Scale in IBM Cloud Bare Metal
- High Performance: Optimized for intensive compute and storage workloads.
- Maximum Throughput: Supports large-scale parallel file access.
- Custom Configuration: Full control over hardware and software stack.
- Persistent Workload Optimization: Ideal for long-running jobs.
- Scalable Clustering: Suitable for large, tightly integrated clusters.
- Instance Storage Support: Leverage high-speed local NVMe or SSD instance storage as part of the Storage Scale filesystem for superior I/O performance and reliability.

Best Practices for Deployment
- Assess Workload Requirements: Match infrastructure to performance and scalability needs.
- Use Dedicated Networks: Separate storage and application traffic.
- Automate with IaC Tools: Use Terraform or Ansible for repeatable deployments.
- Monitor Proactively: Implement monitoring and alerting for health and performance.
- Leverage Data Tiering: Optimize storage costs with policy-based placement across SSD, HDD, and cloud object storage.
Recommendation
- If your goal is to maximize performance and reliability using instance storage as part of the Storage Scale cluster, IBM Cloud Bare Metal is the better choice.
- If you're using instance storage for temporary data or caching, and your workload benefits from agility and cloud-native integration, IBM Cloud VSI is a good fit.
