Data path connection
Fault-tolerant data paths, yet Logical
partitions can not failover to a partner
controller in the event of controller failure.
Host channel bandwidth
6400 MB/s
Above is the sample drawing showing simple end-to-end connections with each SFP
port connected to a host adapter. Multiple logical drives, logical volumes, and logical
partitions can be created and each mapped to the corresponding host channel
ID/LUN combinations.
Note that Infortrend’s EonPath multi-pathing software or Linux Device Mapper is
necessary for controlling and optimizing the access to logical drives via multiple data
paths.
