Physical machines at Rocquencourt

hypervisors

The hypervisors mostly use local storage on the form of internal SSDS but also have access to a Ceph cluster.

NFS server

There is only one NFS server managed by Software Heritage, uffizi.internal.softwareheritage.org. That machine is located at Rocquencourt and is directly attached to two SAS storage bays.

NFS-exported data is present under these local filesystem paths:

/srv/storage/space
/srv/softwareheritage/objects

belvedere

This server is used for at least two separate PostgreSQL instances:

  • softwareheritage database (port 5433)

  • swh-lister and softwareheritage-scheduler databases (port 5434)

Data is stored on local SSDs. The operating system lies on a LSI hardware RAID 1 volume and each PostgreSQL instance uses a dedicated set of drives in mdadm RAID10 volume(s).

It also uses a single NFS volume:

uffizi:/srv/storage/space/postgres-backups/prado

banco

This machine is located in its own building in Rocquencourt, along with a SAS storage bay. It is intended to serve as a backup for the main site on building 30.

Elasticsearch cluster

The Elasticsearch cluster only uses local storage on its nodes.

Test / staging server

There is also orsay, a refurbished machine only used for testing / staging new software versions.

Ceph cluster

The Software Heritage Ceph cluster contains three nodes:

  • ceph-mon1

  • ceph-osd1

  • ceph-osd2
