HP BladeSystem modular architecture key benefits

• Rapid deployment/redeployment saves valuable time
– Server blades and interconnect switches can be installed and ready for immediate automated
provisioning
– Easy access to most pluggable components from the front of the rack, including server blades,
hot-plug hard drives, and interconnect options
– Easily add server blade capacity as needed without disrupting the system
• Innovative design dramatically cuts network and power cables compared to traditional servers
– As few as one network cable for as many as 16 server blades using the interconnect switch
options
– Designed for headless management, eliminating the need for keyboard, video, and mouse cables
for each server and a KVM switch infrastructure
– Rack-centralized power subsystem eliminates individual server power cables as well as the clutter
and cost of power distribution units (PDUs)
– Modular interconnect design enables server blades and interconnect options to be rapidly added
and replaced without re-cabling Ethernet and FC connections
– Server blade management module on enhanced server blade enclosures provides a single
network cable connection for managing up to 16 server blades simultaneously
• Designed to protect your investment
– New HP BladeSystem p-Class 1U Power Enclosure is ideal for small blade deployments such as in
remote office locations and is compatible with all server blades, networking, storage options.
– Broad server blade portfolio enables complete, end-to-end solutions, including enterprise
applications and high-performance computing clusters using modular building blocks.
– Server blades and network interconnect options can be mixed in the same blade enclosure while
operating independently and running different operating systems and applications. – HP BladeSystem enclosures may be installed in HP, telco, and third-party racks. – HP BladeSystem enclosures may share racks with traditional servers, networking, and storage
devices. – Power and network interconnect options support all current and future
ProLiant BL p-Class server blades, including the latest AMD Opteron-based server blade models. – FC SAN connectivity options support HP and select third party storage products.
• Availability features to provide peace of mind – Redundant, hot-plug power supplies
Hot-plug SCSI hard drives and integrated RAID controller on some blade models
– – Dual-port FC SAN connectivity – Multiple general-purpose NICs on each server blade for redundant connections to data networks – Redundant ROM on each server blade – Redundant pairs of hot-plug interconnect switch options

HP BladeSystem manageability key benefits

• Quickly configure both server blades and interconnect switches from a centralized deployment console using HP ProLiant Essentials Rapid Deployment Pack (RDP).
– Configure tens to hundreds of server blades simultaneously in a fraction of the time required to
configure conventional servers using multicasting
– Automatically restore the role of a previous blade to a
new server blade
– Integrate interconnect switch scripts in RDP for
deployment interconnect switches as well as server blades
• Leverage IT personnel by managing a larger number of server blades both locally and remotely with less time and effort.
– Preboot eXecution Environment (PXE) technology
enhances remote access by installing and configuring operating systems to boot over a network.
– iLO Advanced functionality ships standard on every
server blade, including full remote console virtual media (diskette and CD-ROM) capabilities.
– Fully integrates with HP Systems Insight Manager (HP SIM) so you can manage ProLiant blades
and traditional servers with the same tools.
• Take greater control of HP BladeSystem environments with HP SIM.
– HP SIM is the easy-to-use, flexible, scalable, and secure
solution for managing HP servers and client devices by providing rapid access to detailed fault and performance information.
– HP SIM provides visualization of server blades and
interconnect switches at both enclosure and at rack levels for better awareness and control of all blade system components.

Hardware components

The HP BladeSystem p-Class solution consists of the following:
• Server blades
• Server blade enclosures
• Network interconnects
• Power subsystem

Function
Server blades contain one or more processors, memory, internal and external storage options, and integrated management. For FC connectivity, server blades must also be configured with FC card or FC HBA options. ProLiant BL30p and ProLiant BL35p Server Blades require a p-Class sleeve for mounting in the enhanced server blade enclosure.
HP BladeSystem p-Class enclosures hold server blades and network interconnect options. Combinations of different server blades are supported in the same blade enclosure.
Each enclosure supports a pair of interconnects for network cable management. The enhanced server blade enclosure also provides a single Ethernet port for connecting to the iLO interface of every installed server blade.
Some server blade models are supported only in the enhanced server blade enclosure. Refer to the enclosure compatibility matrix on the HP website,
http://h18004.www1.hp.com/products/blades/components/Compatibility­Matrix.html
HP BladeSystem p-Class interconnects pass the network adapter (NIC) signals from 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 pass­through capability.
Power enclosure with power supplies
(Not needed if using facility
-48 VDC ±10%)
Power distribution (used only with 3U power enclosures)
Note: Power requirements for an HP BladeSystem p-Class solution: 200 V to 240 VAC, 30 A or facility DC –48V ±10%
The HP BladeSystem p-Class system offers two power enclosure options:
• The 1U power enclosure provides redundant power for a single server blade enclosure. It is ideal for remote offices, small businesses, or environments that do not have three-phase power available.
• The 3U power enclosure and power distribution components provide redundant power for multiple server blade enclosures. This solution is ideal for datacenter rack deployment. The 3U power enclosures are available in single-phase and three-phase models.
Power is carried from the 3U power enclosure(s) to the server blade enclosure(s) through bus.
Bus bars are available in mini and scalable versions depending on the number of server blade enclosures being deployed.
