Cable Connection Principle
l Hosts and storage devices are connected through Fibre Channel
switches. Each data center has two Fibre Channel switches.
l Each Fibre Channel switch has at least N ports to connect hosts and
storage devices. N = 1 x Number of Servers + 2 x Number of
Storage Devices.
l Host-Fibre Channel switch connection: Each host has at least two
Fibre Channel ports to connect two Fibre Channel switches of the
data center. It is recommended that the two ports be separated on two
HBAs.
l Storage device-Fibre Channel switch connection: Each controller has
at least two ports to connect two Fibre Channel switches of the data
center. It is recommended that the two ports be separated on two
Fibre Channel interface cards.
l The HyperMetro replication network between storage devices uses
Fibre Channel switches for connection. Each data center has two
Fibre Channel switches.
l Storage device-Fibre Channel switch connection: Each controller has
two Fibre Channel ports to connect two Fibre Channel switches of the
data center. It is recommended that the two ports be separated on two
Fibre Channel interface cards.
l Dense wavelength division multiplexing (DWDM) devices are
recommended for data center interconnection.
l If the HyperMetro replication network is a Fibre Channel network,
Fibre Channel switches are cascaded in one-to-one mode. If the
HyperMetro replication network is an IP network, Ethernet switches
are cascaded in one-to-one mode.
l The quorum server is connected to storage devices through Ethernet
switches. Each data center has two Ethernet switches.
l Each controller of a storage device has one IP port to connect to one
Ethernet switch of the data center.
l The quorum server is connected to Ethernet switches. It is
recommended that two IP ports be separated on two network adapters
to connect two Ethernet switches at the quorum site.
l An Ethernet switch is used for management. The management
network ports of the host and controller are connected to one Ethernet
switch of the data center.
l You can use BCManager eReplication to manage networks. For
details, see Business Continuity and Disaster Recovery Solution
V200R001CXX User Guide (Active-Active Mode). For details about
how to obtain the documentation, see
