the server blades to external networks. Several options are available:
•Patch Panel interconnects route each NIC signal individually from the server
blades to the customer network.
•Interconnect switches consolidate the server blade NIC connections to just a
few uplinks, reducing the number of cables needed to connect the solution to
your network.
Both patch panel and interconnect switches are available with or without FC pass-
through capability.

ProLiant BL p-Class server blade SAN connectivity
The ProLiant BL p-Class server blades are optimized for HP StorageWorks arrays, and can attach to
select third-party SAN solutions. In addition, the server blades can integrate with "fused" NAS and
SAN configurations, providing the ability to work in file and block environments seamlessly. HP
StorageWorks arrays include:
•StorageWorks MSA 1000
•StorageWorks Enterprise Virtual Array (EVA)
•StorageWorks EMA/MA arrays
•StorageWorks XP
Select Hitachi and EMC models are compatible.
All StorageWorks models listed support SecurePath for multi-path functionality.
All ProLiant server blades support redundant FC SAN connections. With the exception of the ProLiant
BL40p Server Blade, all BL p-Class server blades support dual port FC adapter options. The ProLiant
BL40p Server Blade has two 64-bit, 100-MHz PCI-X slots that enable redundant FC SAN connectivity
using standard host-bus adapter cards.
FC connectivity with ProLiant BL20p, BL25p, BL30p, BL35p, and BL45p series server blades
FC signals are routed from the configured server blade through the blade enclosure backplane to the
interconnect modules. Optical transceivers added to the interconnect modules provide connectivity to
the external fabric.
For FC SAN connectivity with ProLiant BL20p, BL25p, BL30p, BL35p, and BL45p series server blades,
an interconnect kit options with FC pass-through capability is required. Both the ProLiant BL p-Class RJ-
45 Patch Panel 2 and the ProLiant BL p-Class GbE2 Interconnect Switch with the GbE2 Storage
Connectivity Kit option provide FC SAN pass-through capability.
The dual port FC adapter option kits each include two SFF transceivers with LC connectors. These SFF
transceivers are installed in the RJ-45 Patch Panel 2 transceiver slots. The SFF transceivers are
universal and can be used with the RJ-45 Patch Panel 2, the GbE2 Interconnect Switch, or Cisco
Gigabit Ethernet Switch Module (CGESM) (with GbE2 Storage Connectivity Kit).
Refer to the QuickSpecs for your specific model of server blade to ensure that you are using the
correct dual port FC adapter option kit. Each server blade model has a unique FC adapter option kit.
Visit the HP website at http://www.hp.com/go/bladesystem for the server blade QuickSpecs.

Specific requirements for attaching ProLiant BL30p and ProLiant BL35p Server Blade to FC SANs
The ProLiant BL30p/BL35p Dual Port FC Adapter Option is based on the Logic ISP2312 chipset. This
chipset carries forward all the features of the ProLiant BL20p G3, ProLiant BL25p, and ProLiant BL45p
Dual Port FC Mezzanine Cards and is an industry standard solution. The features of the Dual Port FC
Adapter include:
•RDP scripted installation for Microsoft® Windows® and Linux
•Boot capability from SAN disk or LUN
•Blade bay to FC switch compatibility established by the server blade
•High availability through redundant paths
The ProLiant BL30p/BL35p FC Adapter has a different subvendor ID than the ProLiant BL20p G3,
ProLiant BL25p, and ProLiant BL45p Dual Port FC Mezzanine Cards. Because the Windows driver is
subvendor ID sensitive, a new backward compatible driver was introduced with the ProLiant BL30p
and the ProLiant BL35p Server Blades. Linux drivers are not subvendor ID sensitive, so the currently
available Linux drivers are compatible.

17
FC port aggregation is required to accommodate the increased number of server FC HBA ports and to
maintain compatibility with the available enclosure backplane signals and interconnect ports. The p-
Class sleeve aggregates the four paths from two ProLiant BL30p or ProLiant BL35p Server Blades into
two physical paths. This innovative port aggregation technology enables up to 16 physical FC ports
from the Patch Panel 2, GbE2 Interconnect Switch, or Cisco Gigabit Ethernet Switch Module to
connect directly to the customer external FC SAN switch. ProLiant BL30p and ProLiant BL35p FC
implementations require the FC SAN switch to support FC-AL public loop login. With few exceptions,
notably McData core switches, most FC switches provide this support. All Brocade SAN switches and
most Cisco SAN devices support this feature.
NOTE: The FC LED on the Patch Panel 2 or GbE2 Interconnect Switch does not display a live link
when using the enhanced server blade enclosure. Port activity information can be obtained from the
FC SAN switch or by using QLogic SANsurfer Blade Management software.
HP BladeSystem p-Class Server Blade Enclosure
ProLiant BL p-Class server blades and network interconnects are housed in a 6U server blade
enclosure. The blades slide into the blade enclosure backplanes for power and network connections.
Each blade enclosure has eight server blade bays in the center of the enclosure and two interconnect
bays at each end. The two interconnect bays are populated with either patch panel interconnects (for
direct signal pass-through) or interconnect switches (for network cable reduction). The middle eight
bays support server blades.
The two types of server blade enclosures are: standard server blade enclosures and enhanced server
blade enclosures. Some server blade models are supported only in enhanced server blade enclosures.
For details, refer to the enclosure compatibility matrix at
http://www.hp.com/go/bladesystem/enclosure/compatability
The enhanced server blade enclosure provides the following:
•A server blade management module that simplifies setup and management by:
–A single physical iLO port for all installed server blades that provides up to 16:1 management
cabling consolidation
–Static IP Bay Configuration for automated configuration of iLO addresses
•Support for all ProLiant BL30p and ProLiant BL35p Server Blades, as well as support for all current
and future ProLiant BL20p, ProLiant BL25p, ProLiant BL40p, and ProLiant BL45p series server blades
•Support for all current and future network interconnect options, including the new CGESMs

18
Figure 12 is a front view of the HP BladeSystem p-Class Blade Enclosure.
Figure 12. Server blade enclosure front view
Features of the server blade enclosure include:
•Management communication—The server blade management module reports thermal, power, and
protection fuse events to all server blades in the blade enclosure. The management module also
facilitates power sharing across enclosures and provides asset and inventory information. On
enhanced server blade enclosures, the server blade management module provides a single RJ-45
connector for accessing all installed server blade iLO interfaces. This feature greatly reduces the
number of network cables needed for management.
•Availability—The server blade management module is hot-plug and can easily be replaced without
interruption to server blades or interconnects. Both electrical and mechanical fuses in the backplane
power feed to each bay protect the power backplane from possible electrical damage.
•Toolless installation—Easily installed with spring-loaded rack rails and thumbscrews. Rack rails are
common between the server blade enclosure and the power enclosure.
•Toolless serviceability—Power backplane, data backplane, and server blade management module
are serviceable without tools and without removing the server blades and interconnects from the
enclosure or removing the blade enclosure from the rack.

HP BladeSystem p-Class Blade Sleeve
The HP BladeSystem p-Class Sleeve is required to support ProLiant BL30p and ProLiant BL35p Server
Blades in the enhanced server blade enclosure. The sleeve is for use with these server blades only.
Figure 14. HP BladeSystem p-Class Blade Sleeve
Features of the HP BladeSystem p-Class Blade Sleeve include:
•Holds up to two ProLiant BL30p or ProLiant BL35p Server Blades in any combination
•Installs into any of the eight blade bays in an enhanced server blade enclosure

20
HP BladeSystem p-Class network interconnect options
Each server blade enclosure must be configured with a pair of network interconnects. These
interconnects slide into the front of the blade enclosure and collect Ethernet and FC (except ProLiant
BL40p Server Blades) signals from all the installed server blades.
Figure 15. HP BladeSystem p-Class Enclosure interconnect locations
Two general categories of interconnect options are available depending on your preferences and
environment:
•RJ-45 Patch Panel interconnects collect Ethernet signals from each server blade and provide
an external RJ-45 connector for cabling to each individual server blade NIC. The RJ-45 patch panel
2 option enables individual sever blade FC signals to pass through the interconnect. Benefits of the
RJ-45 Patch Panel options include:
–Connects signals directly to your LAN and SAN
–Offers the lowest blade solution price
–Requires no software or management
–Provides FC signal pass-through (RJ-45 Patch Panel 2 only)
•Interconnect Switches consolidate the Ethernet signals from the server blades to a smaller set of
external copper-based or fiber-based uplink ports for connection to your network. Similar to the
RJ-45 Patch Panel 2, select interconnect switch options pass through individual FC signals. Benefits
of the interconnect switch options include:
–Reduces the number of network cables needed for each server blade enclosure
–Reduces the number of ports used on core network switches
–Enables fully manageable and configurable interconnects
–Provides FC signal pass-through (GbE2 Interconnect and Cisco Gigabit Ethernet Switches only)
The four specific HP BladeSystem p-Class interconnect options are shown in Table 9.
