Connect servers to storage using FC: switch or direct attach ?


my scenario:

i have ds3400 disk system dual controller fibre channel storage equipped 2 controllers each equipped 2 4-gbps fc ports, total of 4 fc ports.

then have 4 servers each equipped 1 ibm 4-gbps fc single-port pci-e hba card.

i'm trying setup windows 2012-r2 hyper-v cluster.

it sufficient connect each server 1 of 4 fc ports of ds3400 or need sort of fc switch obtain fact if 1 storage's controller crash cluster still obtain access storage ?

thank support !

"what "fc clusters" expecially ?"

a failover cluster uses fibre channel storage.

okay, looking @ configuration, not able configure highly available fc cluster.  apologize. glanced @ configuration first time , did not read details.

"servers each equipped 1 ibm 4-gbps fc single-port pci-e hba card"

each server need 2 hbas each server can connect both fc controllers in storage array.  need configure mpio on each server.

in environment, technically switch not needed because have 4 ports on each of fc controllers in san array, not optimal configuration because each server going use 1 of ports on each controller (when second hba in each server).  means cannot more 4 servers connected array.  makes more sense have two switches in between.  way need 2 connections each switch, total of 2 ports used on storage array.  connect many more 4 nodes storage array connecting them switches.
