As a basic rule of thumb, use the settings from the table below...
| VMs# | vCPU | Cores | Memory (GB) | OS Disk (GiB) | Data Disk (GiB) |
|---|---|---|---|---|---|
| < 50 | 8 | 1 | 8 | 20 | 128 |
| 50 - 200 | 8 | 2 | 16 | 20 | 128 |
| 200 - 500 | 16 | 2 | 32 | 20 | 128 |
| >500 | Consider using multiple HYCU’s | ||||
Note If production cluster node has 4 physical sockets you can consider increasing Cores to 4 and lower the vCPU accordingly.
Various HYCU configuration settings also impact HYCU’s resource requirements. Make sure you follow these recommendations...
- If x is concurrency settings of all HYCU targets combined, make sure HYCU is configured with x+1 vCPU
- If using cloud or tape targets, minimum recommended vCPU and memory is 16
- If using HYCU compression:
- add 1 GB of memory per job utilizing compression
- add 1 vCPU for two jobs utilizing compression
- If using HYCU encryption there are no special resource requirements upfront, adjust the sizing later on if required
To backup Nutanix file shares, HYCU will use one or more HYCU Instances. Default starting configuration for HYCU instance is 8 vCPU, 1 Core and 16 GB of memory.
Based on the file server sizes and distribution, following best practices should be applied...
- Have at least one HYCU Instance per Nutanix cluster hosting Files server(s).
- If backing up a share with more then 1 million files, increase vCPU and memory to 16.
