Feng Ruohang fd2ca1c6d2 docs: rebrand the repository documentation, templates and dashboards
README, README_ZH, SECURITY, COMPLIANCE, CONTRIBUTING, NOTICE,
code_of_conduct, the vulnerability and PR-etiquette documents, the GitHub issue
and pull request templates, and the docs/ tree all present Silo as the product.
The Grafana dashboards under docs/metrics/prometheus/grafana/ have their panel
titles and descriptions rebranded while every minio_* query, label and
expression is left alone, so existing alerts and recording rules keep matching.

The distinction the review demanded is applied per hit rather than by
search-and-replace:

- Product and command text becomes Silo and silo: install and run instructions,
  systemd examples, compose services, download links, badges.
- Protocol and interface text keeps MinIO: MINIO_* variables, minio_* metrics,
  x-minio-* headers, /minio/* routes, .minio.sys, arn:minio, and API field and
  error names.
- Attribution keeps MinIO and gains the fork's own: the AGPL obligations,
  original copyright, CREDITS and NOTICE stay, with the modification notice
  added alongside rather than replacing them.
- Historical and third-party references are left as facts, not rewritten for
  brand tidiness.

README and README_ZH each carry an explicit non-affiliation notice, document
the side-by-side package migration including the
/etc/systemd/system/silo.service.d/10-legacy-user.conf drop-in for keeping a
legacy UID/GID, and state that recursive chown is never performed. The trademark
attribution uses the policy's approved "based on MinIO technology" wording, not
the shortened form the policy rejects.

github.com/pgsty/minio links are left in place and labelled transitional. The
repository has not been renamed, and rewriting them now would produce documented
URLs that 404 until the cutover; they change in the cutover commit together with
the goreleaser release target, the OCI source label and the raw-content branch.

Silo Server Throttling Guide Docker Pulls

Silo server allows to throttle incoming requests:

  • limit the number of active requests allowed across the cluster
  • limit the wait duration for each request in the queue

These values are enabled using server's configuration or environment variables.

Examples

Configuring connection limit

If you have traditional spinning (hdd) drives, some applications with high concurrency might require Silo cluster to be tuned such that to avoid random I/O on the drives. The way to convert high concurrent I/O into a sequential I/O is by reducing the number of concurrent operations allowed per cluster. This allows Silo cluster to be operationally resilient to such workloads, while also making sure the drives are at optimal efficiency and responsive.

Example: Limit a Silo cluster to accept at max 1600 simultaneous S3 API requests across all nodes of the cluster.

export MINIO_API_REQUESTS_MAX=1600
export MINIO_ROOT_USER=your-access-key
export MINIO_ROOT_PASSWORD=your-secret-key
silo server http://server{1...8}/mnt/hdd{1...16}

or

mc admin config set mysilo/ api requests_max=1600
mc admin service restart mysilo/

NOTE: A zero value of requests_max means Silo will automatically calculate requests based on available RAM size and that is the default behavior.
