What is IBM Cloud Block Storage
IBM Cloud Block Storage is a cloud block storage service on IBM Cloud that provides persistent volumes for virtual servers and containerized workloads. It targets infrastructure and platform teams that need attachable storage for databases, enterprise applications, and stateful services. The service offers multiple performance tiers and integrates with IBM Cloud compute and Kubernetes for provisioning and lifecycle operations.
Persistent volumes for IBM Cloud
The service provides durable block volumes that can be attached to IBM Cloud compute instances and used by stateful workloads. It supports common operational needs such as volume creation, attachment, resizing, and snapshot-based protection. This makes it suitable for teams standardizing storage operations within IBM Cloud environments.
Performance tier options
IBM Cloud Block Storage offers different performance profiles (e.g., IOPS/throughput-oriented tiers) to align cost and performance with workload requirements. This helps teams place transactional databases and general-purpose application storage on appropriate tiers without changing application architecture. Tier selection can reduce overprovisioning compared with a single fixed-performance offering.
API and automation support
The service is accessible through IBM Cloud APIs and console workflows, enabling infrastructure-as-code and automated provisioning. It integrates with IBM Cloud services commonly used for compute and orchestration, supporting repeatable environment builds. This is useful for DevOps teams managing multiple environments and standardized deployment pipelines.
Primarily IBM Cloud scoped
IBM Cloud Block Storage is designed for workloads running on IBM Cloud, so organizations operating across multiple clouds may need additional tooling for consistent storage policy and portability. Data mobility and operational consistency across providers typically require separate replication, migration, or abstraction layers. This can increase complexity for multi-cloud strategies.
Storage management breadth varies
Compared with dedicated storage management platforms, built-in capabilities focus on block volume lifecycle rather than broad, cross-environment data management. Advanced features such as unified governance across heterogeneous storage, deep analytics, or extensive third-party array integration may require additional products or processes. Teams with complex storage estates may find the management layer less comprehensive.
Cost and performance tuning effort
Selecting the right tier and sizing volumes for IOPS/throughput can require benchmarking and ongoing monitoring to avoid cost inefficiency or performance bottlenecks. Snapshot retention and capacity growth also need active management to control spend. Organizations without mature FinOps/ops practices may experience unexpected cost variability.
Plan & Pricing
Pricing model: Pay-as-you-go (usage-based: capacity + IOPS + throughput; hourly or monthly billing available) Free tier/trial: New IBM Cloud accounts receive starter credits (e.g., $200 for 30 days); additional promotional VPC credits (e.g., VPC1000) may be available. Example costs:
- Gen2 SDP profile (Block Storage for VPC): Capacity: $0.08/GB/month; IOPS: first 3,000 IOPS included, then $0.005 per IOP/month; Throughput: first 125 MB/s included, then $0.04 per MB/s/month.
- Cross-region snapshot copy billing (example): Data transfer: $0.02/GB (one-way); Snapshot storage in target region: $0.0523/GB/month (US multi-zone regions; regional pricing may vary). Other notes: Predefined Endurance profiles expose IOPS-per-GB tiers (bronze: 2 IOPS/GB; silver: 4 IOPS/GB; gold: 10 IOPS/GB) and different capacity ranges per profile. Exact regional prices, additional profiles, and any reservation/commitment discounts are shown in the IBM Cloud Catalog/console. (Prices and allowances may vary by region and are subject to IBM terms.)
