Crush bucket - pod?
From the lecture:
CRUSH is designed to be aware of the infrastructure
The CRUSH Map includes details of physical & network infrastructure
‒ The default hierarchical list of infrastructure elements:
- OSD, host, chassis, rack, row, pdu, pod, room, datacenter, region, root
‒ These elements are known as CRUSH Buckets
I think pdu is "Power Distribution Unit". What is pod? (Power xxxx xxxx)
