[Linux-cluster] GFS, iSCSI, multipaths and RAID

[Michael O'Sullivan]

Thanks Jacob,

Originally we designed a full core-edge configuration with ethernet 
switches, but our design algorithms (initially for Fiber Channel) did 
not account for the tree structure of ethernet when using unmanaged 
switches (this is relatively straightforward to incorporate, but we had 
already purchased the network...!). However, we do have two unmanaged 
switches connecting the servers to the storage devices so there are two 
paths between all the boxes.

Thanks, Mike
