Gluster Scale Out Storage for Cloud using Computational Storage Drives CSD 

Hyperscalers has developed a storage solution based on Gluster FS and Computational Storage Drives by ScaleFlux. The result: The ability to expand capacity by 150%, double the read and write performance and halve the cost per TB. 

Gluster provides an open-source platform for scale-out public and private cloud storage. When delivered as part an appliance by Hyperscalers, service providers can realise newfound benefits around capacity, performance and cost based on pre-engineered outcomes that can be delivered quickly and reliably. 

Expanding the Capacity of Drives CSD 

The following command can be used to expand the logical capacity of the drive, i.e., the capacity visible to the operating system. 
1. $ sfx-nvme sfx change-cap <device> --cap=<NUM>|-c=<NUM> 
Example: 
2. $ sudo sfx-nvme sfx change-cap /dev/sfdv0n1 -c 9600 

Expanding the logical capacity requires that the corresponding data compression ratio is achieved. For example, if the data is known to have a compression ratio of approximately 3:1 (i.e., 300G of data is compressed to 100G), then increasing the logical capacity of a 3.2T drive to 6.4T can be considered safe.

Architecture

The system architecture for GlusterFS distributed network filesystem that is deployed using this document is as shown in the Figure 5 Gluster FS system architecture

Testing the Appliance

The test is conducted to attach the client to the target exposing the ScaleFlux CSD 2000 drives as a logical volume. Sequential read and write tests are performed using the IOMeter tool running on a windows machine pinging the dynamo service running on the Linux target machines

Expanded Drive Logical Volume Test

When the CSD is tested after creating a logical volume with two drives of its actual provisioned capacity, the sequential read speed reached to about 4.2GB/s and sequential write speed reached to about 3.2GB/s.
