Manage Compute NodesCopy link
Compute Nodes are special nodes in the Cohesity cluster that provide dedicated CPU and memory to run resource-intensive apps and services. These nodes do not store any data and do not require disks other than the boot disk. Nodes are automatically detected as compute nodes or can be designated as compute nodes at the time of adding nodes to a Cohesity cluster. Compute nodes are only required if you are running resource-intensive applications.
You can run multiple applications or multiple instances of a single application on a compute node.
System RequirementsCopy link
The following are the system requirements for a compute node:
- System Disk : 1 x 240GB
Must be SSD (HDD not supported)
Recommended to have 2 system disks with the same capacity for high availability.
Do not configure any hardware RAID on the two system disks, if the system disks are connected to a RAID controller. You must configure the RAID controller and both the system disks as JBOD mode in the hardware system setup.
System disk must be less than 800 GB
Any additional drives must be removed from the system
- Memory : 128 GB (minimum)
- Intel CPU 32 Cores (minimum) with each core at 2.1GHz or above
Supported Hardware PlatformsCopy link
Cohesity also extends support for hardware platforms from the following partners as long as they meet the minimum system requirements.
| Cohesity certified platforms | Reference Links |
|---|---|
| C5K CNG2 Compute Node | C5000 Series Setup Guide |
| Bring your own Hardware (BYOH) | HPE, Cisco, DELL, Fujitsu, or Lenovo - any x86 that meets compute node requirements. |

Bring Your Own Hardware (BYOH) |
Minimum Specifications* |
|---|---|
|
CPU |
2 x 16 Cores (Intel or AMD), min 2.0GHz |
|
Memory |
128GB |
|
Boot drives |
2 x 240GB SATA/NVMe M.2 SSDs Note: Boot SSD drive size should not be more than 800GB (max limit) |
|

*The requirements can be more unless explicitly specified.
If you use a hardware model other than the Cohesity-certified platforms, it is recognized as 'Product Name : Unknown Platform' and supported as long as it meets the minimum system requirements.
Manage Compute NodesCopy link
Nodes configured with VIPs cannot be designated as or automatically added as compute nodes.
Automatic Addition of Compute Nodes
Adding a physical compute node is seamless for the user with no additional configuration. If a physical node is added, and it meets the minimum specifications for a compute node, it will be automatically added as a Compute Node, unless it is a pre-certified data node platform.
Delete Compute NodesCopy link
Deleting a compute node is like deleting any other node. For more information, see node delete.
