Deduplication – By the Numbers

Atlantis HyperScale appliances come with effective capacities of 12TB, 24TB and 48TB depending on the model that is deployed. These capacities are what we refer to as effective capacity, i.e., the available capacity after in-line de-duplication that occurs when data is stored onto HyperScale Volumes. HyperScale Volumes always de-duplicate data first before writing data down to the local flash drives. This is what is known as in-line deduplication which is very different from post-de-duplication which will de-duplicate data after it is written down to disk. The latter incurs storage capacity overhead as you will need the capacity to store the data before the post-process de-duplication is able to then de-duplicate. This is why HyperScale appliances only require three SSDs per node to provide the 12TB of effective capacity at 70% de-duplication.

Breaking it down

HyperScale SuperMicro CX-12
Number of nodes 4
Number of SSDs per node 3
SSD capacity 400GB
Usable flash capacity per node 1,200GB
Cluster RAW flash capacity 4,800GB
Cluster failure tolerance 1
Usable flash capacity per cluster 3,600GB
Effective capacity with 70% dedupe 12,000GB

Formulas

Formula for calculating Reduction Rate

Taking the capacity from a typical HyperScale appliance of 3,600GB, this will give 12,000TB of effective capacity.

Summary

HyperScale provides a guarantee of 12TB per CX-12 appliance, however some workloads such as DEV/TEST private clouds and stateless VDI workloads could see as much as 90% data reduction. That’s 36,000GB of effective capacity. Do the numbers yourself, in-line de-duplication eliminates the need for lots of local flash drives or slower high capacity SAS or SATA drives. HyperScale runs the same codebase as USX and as such utilizes RAM to perform the in-line de-duplication which eliminates the need for add-in hardware cards or SSDs as staging capacity for de-duplication.

Introducing Atlantis HyperScale

What is it?

A hyper-converged appliance running pre-installed USX software on either XenServer or VMware vSphere and on the hardware of your choice – Lenovo, HP, SuperMicro and Cisco.

How is it installed?

HyperScale comes pre-installed by Atlantis Channel Partners. HyperScale runs exactly the same software as USX, however HyperScale is installed automatically from USB key by the Channel Partner. When it is delivered to your datacenter, it is a simple 5 step process to get the HyperScale appliance ready to use.

Step 3

Step 4

Step 5

Done.

What do you get?

The appliance is ready to use in about 30 minutes with three data stores ready for use. You can of course create more volumes and also attach and optimize external storage such as NAS/SAN in addition to the local flash devices that come with the appliance.

Key Differentiators vs other Hyper-converged Offerings

Apart from lower cost (another post to follow) or you can read this post from Chris Mellor from The Register, HyperScale runs on exactly the same codebase as USX. USX has advanced data services that provide very efficient data reduction and IO acceleration patented technology. For a brief overview of the Data Services please see this video.
