Connection
3.3.4 Simple End-to-End Connection
The above example demonstrates a simple end-to-end connection where each SFP
port is connected to a host adapter. Multiple logical drives, logical volumes, and
logical partitions can be created and mapped to the corresponding host channel ID/
LUN combinations.
EonPath multipath software or Linux Device Mapper is necessary for controlling and
optimizing the access to logical drives via multiple data paths.
Channels Controller A Controller B
Host CH0, CH1, CH2, CH3 CH0, CH1, CH2, CH3
Configuration Information
RAID controller 2
Host server 2
Data path connection Fault-tolerant data paths
Host channel bandwidth 6400 MB/s
Note! If a logical drive can be accessed by different servers, file locking, FC
switch zoning, port binding, and multipath access control will be
necessary in order to avoid access contention.
