Block Storage

Block storage at maximum capacity or for precisely  what you need.

Our impressive SAN flexibility, diligence and durability will give you the best local disk performance. Install block storage up to a maximum of 12TB to incrementally increase your storage capacity open to your bare metal or virtual servers.

You can also tailor-make the performance and features of your block storage volumes. Use Provision Endurance resources along with photos and replication or build your own high-powered Performance environment with IOPS distributed.


Your data is safe, long-lasting and resilient with us, thanks to our top-notch infrastructure.


Access stored data directly using the os, reducing any time lag between accessing and receiving data.

No hidden costs

Your monthly charges are reflected in each bill. We do hide any costs and all details are available via API.

Storage. Data Center style.

Get the storage you need, where you need it.

Durable: Our block storage infrastructure protects against data loss and saves you from having to create and manage operating system-level RAID arrays. This durability also means your data is protected during any necessary maintenance and in the event of equipment failure.

Allocated IOPS: Volumes are provisioned with customizable allocated levels of IOPS to meet your workload’s unique storage needs. Multiple volumes may be striped together to achieve even better performance.

Concurrent Access and Highly Available Connectivity: iSCSI-based block storage volumes are exposed to authorized devices via redundant multipath I/O (MPIO) connections, and multiple devices can mount a block device simultaneously in a clustering configuration.

Snapshots & Replication (Endurance only): Efficient, point-in-time snapshots are captured non-disruptively and engineered to minimize space. Snapshots can be replicated to select SoftLayer data centers.

Global Footprint: Block volumes can be provisioned alongside your cloud servers in SoftLayer data center locations around the world.

Block Storage 101

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 enterprise-grade spinning disks—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.
