777393 - design a higher capacity panda chassis

Status: RESOLVED FIXED

(Infrastructure & Operations :: RelOps: General, task)

Description

[Jake Watkins [:dividehex]]

We currently have a panda chassis design that will accommodate up to 12 pandas in a 4U rack space.  Since rack space is limited in our datacenters, we are going to work on a higher density design.

We are still working out software details but these hardware requirements will help Jake get started on a design.

Hardware requirements for Android Panda Chassis:

- Proper airflow, cold aisle compatible
- Self-contained power supply that matches datacenter voltage requirements (208v)
- Stable mechanical mounting
- Ability to replace individual pieces of faulty internal hardware (FRUs)
- Modular internal design: power, networking, cooling
  - chassis on rails for easy access
  - chassis lid should be easily removable for maintenace
  - easily removable mounting brackets for pandaboards
  - RelEng does not have a requirement for hot swap
- Physical hardware management
  - Maximizing top-of-rack switch usage
  - Maximizing rack space usage/power density while still allowing for proper cable management
- Remote power management
- Remote imaging for a larger percentage of failure modes
- Adequate internal density for future growth within confined datacenter space
