S3 Storage Limits

To ensure stable operation of S3 storage, limits are imposed on the number of requests and data transfer speeds.

All limits apply separately to each bucket.

Request Rate Limits

The following limits apply to each bucket:

Operation Type	Maximum Request Rate
PUT, POST, DELETE	5 requests per second
GET, HEAD	25 requests per second

Exceeding these limits may result in request errors.

Data Transfer Speed Limits

Each bucket has independent limits for uploading and downloading data:

Data Transfer Direction	Maximum Speed
Upload (to the bucket)	100 Mbit/s
Download (from the bucket)	100 Mbit/s

Upload and Download limits are independent of each other.

This means that using a single account, you can simultaneously upload data to a bucket at speeds of up to 100 Mbit/s and download data from the same bucket at speeds of up to 100 Mbit/s.

Therefore, simultaneous uploads and downloads do not reduce each other's available bandwidth within the specified limits.

Configuration Recommendations

To ensure proper operation of S3 storage, we recommend limiting the number of concurrent requests on the client side.

When using AWS CLI, configure the max_concurrent_requests parameter in the ~/.aws/config file.

Configuration example:

[default]
region = us-east-1
endpoint_url = https://c1.de.fornex.io
s3 =
    max_concurrent_requests = 5
    addressing_type = virtual

Parameter descriptions:

• max_concurrent_requests — the maximum number of concurrent requests. The recommended value is 5.
• region — the region used to connect to S3 storage.
• endpoint_url — the S3 storage endpoint URL.
• addressing_type — the bucket addressing method. The virtual value specifies virtual-hosted-style addressing.
