Open Source Software Equipment Manager, or OSSEM for short

OSSEM overview

Notes for OSS Equipment Manager (OSSEM, pronounced 'awesome') for LabOps teams:

This OSS is meant to be an alternative to something like Qualisystems, it will have a resource structure, reservations, equipment automation, and more. We plan to create a software suite that will both manage your equipment, allow user reservations, generate topologies to share, and automate deployment of equipment and VMs.

Model breakdowns

Here we will go over each model and its purpose

Site

A site is a large physical location, typically a city, campus, or building

Fields:

• Required
  • Name

Generated Fields:

• Number of Rooms
• Number of Racks
• Number of devices

Datacenter

The Datacenter would be where something is stored, valid children would be things such as Rack, Device, etc...

Fields:

• Required
  • Name
  • Location (typically address and floor)
• Optional
  • Square footage

Generated Fields:

• Number of racks
• Number of Devices

Rack

A rack represents an equipment rack. If tied to a managed CDU it will be able to better estimate the used and available power, otherwise it will rely on the power required field for Devices.

Fields:

• Required
  • Name (just a text field so numbers work fine too)
  • Total Rack Units
  • Datacenter
• Optional
  • Power capacity

Generated Fields:

• Occupied U space
• Free U space
• Estimated power utilization
• Estimated free power

Location

A wrapper class to encapsulate Site, Datacenter, Rack. this allows us to put one location field in the Resource class in order to make it so you can have any or all of those classes listed for the location.

On whatever form a user fills out for this, it should populate the other fields when it can, for instance, if you pick a Datacenter it should populate the Site automatically.
