MSA 1040 connection guidelines
•
No host interface cables are shipped with MSA
1040 arrays. For a list of cables available from
HP, see the HP MSA 1040 QuickSpecs.
•
In direct-connect deployments, connect each host
to the same port on both of the MSA controllers.
•
In switch-connect deployments, connect an MSA
Controller A port and the corresponding MSA
Controller B port to one switch, and connect a
second MSA Controller A port and the
corresponding MSA Controller B port to a
separate switch.
Example MSA 1040 connections
The following image illustrates connecting an MSA
1040 FC to two switches, and the two switches
connecting to two servers. Eight Fibre Channel cables
are required.
For more cabling examples, including connecting
directly to a server, see the HP MSA 1040 Cabling
Configuration Guide.
Step 4. Connect the MSA 1040 to a remote
management host (optional)
A remote management host directly manages systems
out-of-band over an Ethernet network.
If a remote management host is included in your
environment, connect an RJ-45 Ethernet cable from the
network management port on each MSA 1040
controller to a switch that your management host can
access (preferably on the same subnet).
Step 5. Connect two Remote Snap-capable MSA
systems to replicate volumes (optional)
The MSA 1040 supports HP MSA Remote Snap
Software, an optional licensed disaster-recovery utility.
This utility performs asynchronous (batch) replication
of block-level data from a volume on a primary MSA
to a secondary volume on the same system or on a
separate, independent MSA system that supports
Remote Snap Software. These two MSA systems
connect through FC or Ethernet switches that are on
the same fabric or network.
For more information about Remote Snap Software,
including cabling requirements and user information,
see the HP MSA 1040 User Guide, HP MSA 1040
SMU Reference Guide, and Remote Snap online help.
Step 6. Connect power cords and power on
devices
IMPORTANT:
•
The power cord must be approved for use
in your country. The power cord must be
rated for the product and for the voltage
and current marked on the electrical ratings
label of the product.
•
Important safety information about power
cords is available in the Safety and
Disposal Guide, found on the Software
Support/Documentation DVD shipped with
the MSA 1040.
Apply power to the devices in the following order:
1.
Connect power cords from the rack to separate
external power sources.
2.
Power on the SAN/LAN switches (if necessary).
3.
Connect each power supply module in all
attached expansion drive enclosures to a power
source in the rack. If the drive enclosures have
power switches, apply power. If the drive
enclosures do not have power switches, they
automatically start.
4.
Wait one minute to ensure that all drives in the
drive enclosure are powered up and ready.
5.
Connect each power supply module in the MSA
1040 to a power source in the rack. The MSA
1040 automatically starts (it does not have a
power switch).
6.
Observe the LEDs on the front and the rear of the
MSA 1040 and any expansion drive enclosures,
and confirm that no LEDs are amber.
7.
Power on the servers (if necessary).
