H A Dmultihost-ipmi-design.md1 # Multi-host IPMI design
12 The current version of OpenBMC does not support multi-host implementation in
13 IPMI commands handling. We have a multi-host system and proposing the design to
14 support multi-host.
20 Issue 1: ipmbridged does not send the channel number (ie HostId) Issue 2: ipmid
21 does not have the information on which IPMB channel the request has come from.
