Linux
There are three configurations supported for Linux host servers:
• Single Path — This configuration utilizes a simplified cabling scheme, but does not provide
redundancy or fault tolerance. It should only be used when the operating system or a higher-level
application is being utilized for data resiliency.
• Symmetric Multipath — A cascading configuration that provides path redundancy, but does not
provide against enclosure loss.
• Asymmetric Multipath — High availability configuration that allows the host server to reach any
enclosure if a path or single enclosure is lost
For multipath configurations, Linux Device Mapper Multipath (DMMP) must be configured. Dell
recommends the Failover Policy. To ensure proper functionality, verify the following values are set
in /etc/multipath.conf:
• path_grouping_policy failover
• failback manual
NOTE: For more details on supported Linux OS’s please see the MD3060 Storage Enclosure Support
Matrix.
