Limitations
To ensure stability of operations and performance for every user, SCS3 has limitations.
Limitations
The following table describes limitations in more details:
| Item per SCS3 endpoint | Default | Maximum - configurable in the portal | Maximum - contact support |
|---|---|---|---|
| Number of buckets per project | 100 | 100 | 1000 |
| Max bucket size (TiB) | 5 | 50 | 200 |
| Max number of objects per bucket (millions) | 10 | 10 | 50 |
The default value is set upon the SCS3 instance creation.
User may increase each item up to the maximum value on their own via the Switch cloud portal.
Additionally, in some case, it may be acceptable to further grow the maximum value. Please contact support if this is needed.
Note
Due to the demand exceeding the current capacity, the maximum quota per SCS3 instance is currently limited to 5TiB.
Average object size
It must be emphasised that the average object size is very important for the stability of SCS3 HDD clusters. The bigger is the average object size, the more stable the service will be.
Important
SWITCH strongly recommends to configure workloads on SCS3 HDD clusters so the average object size would be at least 512kB+ big.
A bigger average size would be even better when possible.
