Cloud Capacity

Here you find how the cloud capacity is calculated.

What is Cloud Capacity?#

Cloud capacity is the capacity you have available to sell to your customers. Here is an overview of how we calculate Cloud Capacity for the different products.

Calculation for RAM#

RAM = (Total CPU nodes * total GB RAM installed per node) - 1 whole node for reservations

Rocket Storage = (Total CPU nodes * (total RS per node / 2 for RAID10 - 1680 GB per node)) - 1 whole node for reservations

Example#

Raw Capacity:

• 384 cores (+128 as extra node)
• 3072GB RAM (+1024 as extra node)
• 46080GB Rocket Storage (+15360GB as extra node)

Cloud Capacity:

• 384 cores (+128 as extra node)
• 3.072GB RAM (+1024 as extra node)
• 18000GB Rocket Storage (+6000GB as extra node)

Calculation for Distributed Storage#

Total GB across 3 nodes, divided by 3 for redundancy, multiplied by 80% because ceph doesn’t work above 80% capacity - ignore OS SSD disks.

Example#

Raw Capacity:

• 23040 GB

Cloud Capacity:

• 6114 GB
