Draft: Pooled Quota

[tbsbdr]

Description

User Stories

• As a serviceprovider I want to set a pool quota so I can issue a quota-fixed invoice.

Value

• support saas businesses

Acceptance Criteria

• add new config option to set an instance-wide pool quota

  • disabled by default (disabled = current behaviour, limit is max. available storage space)

• change existing wording quota -> "Unrestricted" to "Pooled - No individual limit"

• pool quota is enforced upon storage-consumption: once actual usage reaches the pool quota, writes are rejected instance-wide, regardless of remaining individual quota (edge-case)

  • user-facing error must state the pool is full, not the personal quota

• personal/space quota is a cap, not a reservation

  • a single cap must be <= pool quota, larger values can not be selected
  • the sum of all caps may exceed the pool quota (overcommit), (this is intended to encourage users to use the cloud-storage)

• edgecase overcommit: a user can hit the pool limit while the ui still shows free personal quota, needs info-message, tbd

• if overprovisioned: show a note "Allocated quota exceeds pool quota by X (Y%). Actual usage stays limited to the pool quota."

• enabling the pool on an existing instance - tbd, eg:

  • existing caps above the pool quota are capped to the pool quota, admin sees the affected entries before applying

• disabling the pool: caps remain and stay in effect, limit is max. available storage space again

+1 for this issue. This is exactly what we need.

Especially the options to modify and turn it on/off on an existing instance is important.
A good addition to this would be to add a metric "used pool storage" to the OC Administrator Role "Dashboard" so an instance admin can review how much his organization has already utilized.
