SMI Bare Metal - Architecture
The SMI enables the deployment of Cluster Manager on Bare Metal servers. The following are some of the salient features of SMI Bare Metal architecture:
-
Enables all the application containers to run on the bare metal servers with enough resource isolation
-
Provides a migration path for SMI on VM to SMI on bare metal
-
Automated bring up at the Data Center
-
Hardware agnostic architecture
The following figure depicts the high-level SMI Bare Metal Architecture:

With the help of a Bootable ISO, the SMI Cluster Manager boots the Linux Kernel from the base image. This allows compatibility with most of the standard hardware platforms. A customized script downloads and writes the HD image using the Initial RAM File System. Also, the Bootable ISOs smaller size - 23 Mega Bytes (MB) - reduces latency.
