Planning the installation 9
• Be sure that the firmware revisions on all VC modules in the domain are at the same revision level. The
active VCM does not allow incompatible modules to be managed as part of the same VC domain. For
more information, see "Firmware requirements (on page 13)."
• Be sure that OA, iLO, server blade system ROM, Ethernet option ROM, and FC option ROM firmware
are up-to-date. For more information, see "Firmware requirements (on page 13)."
• Determine which mezzanine cards, HBAs, and interconnect modules are going to be used and where
they will be installed in the enclosure. For installation and information on mapping server ports to
interconnect bays, see the appropriate HP BladeSystem enclosure setup and installation guide on the
Installing tab of the HP BladeSystem Technical Resources website
(http://www.hp.com/go/bladesystem/documentation)
• Determine the Ethernet stacking cable layout, and ensure that the proper cable and transceiver options
are ordered. Stacking cables enable any Ethernet NIC from any server to be connected to any of the
Ethernet networks defined for the enclosure.
o For information on cable layout, see "Recommended stacking connections (on page 21)."
o For information on supported cable and transceiver options, see the Virtual Connect module
QuickSpecs on the Installing tab of the HP BladeSystem Technical Resources website
(http://www.hp.com/go/bladesystem/documentation).
• Determine which Ethernet networks will be connected to or contained within the enclosure.
Most installations will have multiple Ethernet networks, each typically mapped to a specific IP subnet.
Virtual Connect Ethernet networks can be contained completely within the enclosure for server-to-server
communication, or connected to external networks through rear panel ports (uplinks). For each network,
the administrator must use the VCM to identify the network by name and to define any external port
connections.
• Determine which Fibre Channel fabrics will be connected to the enclosure.
Each uplink has a capability of aggregating up to 16 server HBA N-port links into an N-port uplink
through the use of NPIV.
• Coordinate with data center personnel to ensure Ethernet network cable connections and Fibre Channel
cable connections to the enclosure are installed or scheduled to be installed.
• Determine the Ethernet MAC address range to be used for the servers within the enclosure.
Server and networking administrators should fully understand the selection and use of MAC address
ranges before configuring the enclosure. For more information, see "MAC address settings (on page
65)."
• Determine the FC World Wide Name (WWN) range to be used for servers within the enclosure.
Server and storage administrators should fully understand the selection and use of WWN ranges before
configuring the enclosure. For more information, see "WWN settings (on page 78)."
• Identify the administrators for the Virtual Connect environment, and identify what roles and
administrative privileges they will require. The VCM classifies each operation as requiring server,
network, domain, or storage privileges. A single user may have any combination of these privileges.
For more information, see the information on local users in the HP Virtual Connect for c-Class
BladeSystem User Guide on the Installing tab of the HP BladeSystem Technical Resources website
(http://www.hp.com/go/bladesystem/documentation).
IMPORTANT: If you plan on using VC-assigned MAC addresses and WWNs and are also
working with server software that will be licensed by MAC addresses or WWNs, assign server
profiles before deploying an image through RDP or attaching a license.
