Block Storage

Local disk performance with SAN persistence and durability

Deploy flash-backed1,2 Bluemix Block Storage with customizable performance and sizes up to 12TB. Increase storage capacity available to your Bluemix Virtual and Bare Metal Servers with a maximum of 48,000 IOPs. Take advantage of snapshots and replication3 when provisioning with Endurance tiers—featuring simple, predefined,

performance levels with simple per GB pricing ideal for most general purpose workloads. Or, build a fine-tuned environment with allocated IOPS from Performance options—ideal for businesses with well understood performance requirements. Protect your data with provider managed, encryption for data at rest.2

Popular Use Cases

NoSQL databases: Provision performance LUN with specific IOPS to achieve specific read/write speeds.

High-transaction workloads: Stripe performance LUNs together to achieve up to 48k IOPS for the most demanding I/O requirements.

High I/O applications: Frequent read/write needs are met with the speed and consistent input/output of performance LUNs.

When data moves fast, ensure your persistent storage can keep up by selecting Performance block storage. Select the storage capacity you need—from 20GB to 12TB—and select the number of IOPS you want dedicated to your block storage volume.

Popular Use Cases

NoSQL Databases : Ideal for NoSQL databases because performance volumes can be provisioned with specific IOPS to achieve specific read/write speeds.

High Transaction Workloads : Stripe performance volumes together to achieve up to 6,000 IOPS to meet even the most demanding I/O requirements.

High I/O Applications : Applications that have frequent reads/writes will benefit from the speed and consistent input/output of performance volumes.

Is block storage right for you?

Block-level storage is an iSCSI-based storage solution provisioned in raw volumes of unformatted blocks and deployed in a SAN environment accessible over SoftLayer’s private network. Some of the most popular use cases for block-level storage include databases, virtual server deployments, and big data analytics.

SoftLayer block storage has been engineered to run on specialized, high-performance storage devices that seamlessly fuse solid-state drives—ideal for computing operations that need higher input/output operations per second (IOPS)—with flash storage—allowing near-limitless scalability while minimizing costs. Your block storage is hosted in the same data center as your SoftLayer virtual and bare metal servers and volumes can be replicated to other SoftLayer data centers over our private network.
