Block Storage

Low latency, high IOPS

OCI Block Volumes use advanced, low-latency NVMe SSDs and nonblocking network connectivity for every host, which provides high IOPS to Oracle compute services. OCI Block Volumes offer the only storage performance SLA among large cloud providers.

Dynamically reconfigure and scale

Easily optimize storage size without provisioning constraints. Extend existing block and boot volumes from 50 GB to 32 TB while they are online without any impact to applications and workloads. Clone existing volumes or restore from backups to move to larger volumes.

Integrated data protection

All volumes have built-in durability and run on redundant hardware to achieve high reliability. Back up block and boot volumes to Oracle Cloud Infrastructure (OCI) Object Storage to enable frequent recovery points.

Match performance with workload

The elastic performance feature allows customers to select and dynamically change the performance of OCI Block Volumes. Depending on their needs, customers can choose from balanced performance, higher performance, or ultrahigh performance levels or lower-cost options, and easily change modes without rebooting. Customers can also enable Block Volume auto-tuning to dynamically scale their application’s performance as their workload demands.

More IOPS, lower cost

Customers running a typical enterprise workload of a 1 TB block volume with 35,000 IOPS requirements can enjoy the cost savings with Oracle Cloud Infrastructure, higher performance volume.

Gain efficiency with volume groups

Volume groups allow customers to take coordinated action across a set of volumes that require management as a group. For example, perform precise, point-in-time coordinated backups and clones across all volumes in the group.

Highly available by design

All volumes are automatically replicated to protect against data loss. Multiple copies of data are stored redundantly across storage servers with built-in repair mechanisms. Block and boot volumes are designed to provide 99.99% uptime.

Block storage cloning

Easily clone existing block volumes without initiating the backup and restore process. Create one or more direct disk-to-disk copies of an existing volume to support scale out, disaster recovery, DevTest, and production troubleshooting.

Integrated backup to OCI Object Storage

Automated and policy-based scheduled backups allow customers to back up block and boot volumes to highly durable Object Storage automatically, without impacting running applications. Scale out copies of data for demanding applications by restoring a backup to multiple block volumes.

Cross-region asynchronous replication

Cross-region asynchronous block volume and time-coordinated volume group replication provide additional options for disaster recovery preparedness. With an RTO of less than a minute to put a replicated volume or volume group back into service, customers can replicate volumes and volume groups directly to another region. Customers pay only for the extra storage amount and network transfer cost to update the replica volumes.

Automate volume and volume group backup

Simplify business continuity after disasters with automated scheduled volume group backups which are time- and crash-consistent. These backups can also be automatically copied to another region at no additional cost beyond the underlying storage cost and any network transfer costs.
