HP MSA 1040 SAN Storage - Manual (Page 31)

Connecting the enclosure to data hosts 31
The first usage option requires valid licensing for the Remote Snap replication feature, whereas the second
option requires that the host computer supports Ethernet, iSCSI, and optionally, multipath I/O.
Connecting direct attach configurations
The MSA 1040 controller enclosures support up to four direct-connect server connections, two per
controller module. Connect appropriate cables from the server HBAs to the controller host ports as
described below, and shown in the following illustrations.
To connect the MSA 1040 controller to a server or switch—using FC SFPs in controller ports—select Fibre
Channel cables supporting 4/8 Gb data rates, that are compatible with the host port SFP connector (see
QuickSpecs). Such cables are also used for connecting a local storage system to a remote storage system
via a switch, to facilitate use of the optional Remote Snap replication feature. The maximum speed
supported for FC is 8 Gbit/s.
To connect the MSA 1040 controller to a server or switch—using 10GbE iSCSI SFPs in controller
ports—select the appropriate qualified 10GbE SFP option (see QuickSpecs). Such cables are also used for
connecting a local storage system to a remote storage system via a switch, to facilitate use of the optional
Remote Snap replication feature.
To connect the MSA 1040 controller to a server or switch—using the 1 Gb SFPs in controller ports—select
the appropriate qualified RJ-45 SFP option (see QuickSpecs). Such cables are also used for connecting a
local storage system to a remote storage system via a switch, to facilitate use of the optional Remote Snap
replication feature.
NOTE: The MSA 1040 diagrams that follow use a single representation for each cabling example. This is
due to the fact that the port locations and labeling are identical for each of the three possible SFP options
supported by the system.
