Introducing 2TB Block Volumes

Hi everyone,

We launched the Oracle Bare Metal Cloud with 256GB block volumes last fall. Since then, we've been working closely with customers and partners to build a wide variety of block volume configurations to support multiple applications, but the appetite for larger volumes and more performance has been tremendous.

Today we are enhancing our Block Volume Service with the addition of larger capacity 2TB block volumes. These volumes are built using the same proven technology in our 256GB block volumes. When you are considering your storage layout and performance or capacity requirements, your application traffic profile and throughput are the two primary factors to consider. I’m happy to share the details for for both of these volume types.

Compared to 256GB block volumes, 2TB block volumes are in increase in both dimensions:

  256GB Block Volumes 2TB Block Volumes
Throughput 48MBS 96MBS
IOPS 1,500 @ 4K Blocksize 6,000 @ 4K Blocksize


Here's a review of high level application categories and design considerations for scale when choosing your storage architecture:

By blending your infrastructure and application capabilities, you can efficiently scale from development and test on 256GB block volumes environment to production with 2TB block volumes. Visit our Bare Metal Storage page and the Oracle Learning Library for more detail.

We're happy to work with you on your cloud application and storage questions. Please send feedback or topics you would like to see covered here.
