The unit prefix used in these paragraphs are wrong, but is a common mistake.  The IEEE 802.3 Ethernet standard uses (b)its as the unit prefix to measure port speeds and not (B)ytes.

This documentation also differs from upstream documentation.

For example

Upstream:
link: https://docs.ceph.com/en/latest/start/hardware-recommendations/#speed

"It takes three hours to replicate 1 TB of data across a 1 Gb/s network and it takes thirty hours to replicate 10 TB across a 1 Gb/s network."

Red Hat Documentation with the incorrect unit prefix and incorrect timeline:

"In the case of a drive failure, replicating 1 TB of data across a 1 GB Ethernet network takes 3 hours, and 3 TB takes 9 hours."
