Hardware Requirements
|
|
=====================
|
|
Ceph OSDs run on commodity hardware and a Linux operating system over a TCP/IP network. OSD hosts
|
|
should have ample data storage in the form of one or more hard drives or a Redundant Array of
|
|
Independent Devices (RAIDs).
|
|
|
|
<Need More Info>
|
|
|
|
Discussing the hardware requirements for each daemon,
|
|
the tradeoffs of doing one ceph-osd per machine versus one per disk,
|
|
and hardware-related configuration options like journaling locations.
