Product Overview
This chapter provides an overview of the main features of the HPE Apollo 480 Cluster platform. The
Apollo 480 Cluster is a custom configured, high performance, compute server that features high-density
computing, up to 80 processors per rack. Each rack can support up to 10 enclosures. Each enclosure will
have redundant power supplies and support either two or four independent nodes within a compute tray.
The last section of this chapter describes operating precautions. Before operating your system, familiarize
yourself with the safety information in that section.
System Features
This section describes the flexible architecture and technical features of the HPE Apollo 480 platform in
the following sections:
HPE Apollo 480 Cabinet (Rack)
The HPE Apollo 480 cabinet is a standalone 42U rack. The 42U rack can hold a variable amount of
compute, up to 40 nodes. An optional top-mounted extension is available to add room for switches or
optional full-width equipment.
Figure 1: Apollo 480 Cluster Cabinet Example
An optional 2U head node spans the width of the rack interior, see the subsection Optional IO Servers
for additional detail. The cabinet’s 24” x 48” footprint approximates that of standard floor tiles and an
optional 3U extension is available for additional head nodes, networking, or ATS equipment.
Hadoop Specialized Rack Option:
The Apollo 480 system can be optionally specialized for Hadoop Reference Implementation (RI) usage.
This version of the rack allocates 36U of space in the lower section of the cabinet. It is configured with
Apollo 480 compute enclosures. A 2U space is reserved for switch installation. The remaining 4U of
space (U39 through U42) is used for the installation of 1U full-width (full-depth) nodes. Only one Hadoop
RI rack is used in each Hadoop cluster configuration.
4 Product Overview
Compute Trays
Each Apollo 480 compute tray can support two or four multiprocessor-based node boards (server
boards). The Apollo 480 Cluster node server boards documented in this guide are based on Intel
chipsets. The compute nodes also house hard drives, graphics or I/O options, as well as fans.
NOTE: Customers requiring AMD™ clusters can check with an HPE sales or service representative for
information on non-Apollo 480 AMD-based cluster offerings available from HPE.
As stated earlier, the Apollo 480 Cluster rack architecture supports up to 40 compute nodes (36 nodes in
a Hadoop RI rack), along with the following features:
• Ability to use a 1U standard-depth head node (multiple nodes in Hadoop configuration);
• Individual node serviceability.
Figure 2: Compute Node Example
Processors
The Apollo 480 Cluster can support the following configuration of processors: 42U-system minimum, with
two processors for each node.
The exact type of processors provided with your system depends on the specific configuration you
ordered. Check with your sales or service representative for information on processor availability,
upgrades, and compatibility. The HPE Apollo 480 Cluster platform uses two Intel Xeon Silver/Gold
(Skylake) processors per motherboard.
Product Overview 5
Figure 3: Example Apollo 480 Motherboard diagram
DIMM Memory
Memory configuration varies depending on the processor board type ordered with your compute nodes.
DIMM population requirements are 12 per server board and standard DIMM speeds are 2,400 MHz. Use
of more than one DIMM per channel will result in the processor operating that channel at 1,600 MHz by
default regardless of the DIMM operational capacity.
Power Supplies
The Apollo 480 Cluster uses two high-efficiency power supplies per enclosure. Depending on your system
configuration and input voltage, each power supply provides a maximum of 2000W of power to the
enclosure.
NOTE: The Apollo 480 power supplies are not installed in the compute trays, but instead alongside the
trays within the rack.
CAUTION: The cabinet power supply cord is used as the main disconnect device. Ensure that a
socket outlet is located or installed near the equipment and is easily accessible.
6Product Overview
Compute Tray Drive Subsystem
Apollo 480 was designed to support SATA or SAS hard disk drives. Each compute tray connects to a front
enclosure that can support up to 48 drives. One rack can support up to 10 enclosures. The Apollo 480
standard nodes only support SATA disk drives. However, by adding an optional SAS HBA, certain
versions of the compute nodes can support SAS disk drives. The disk drives installed in the rear of the
compute nodes support software and hardware RAID 0 and 1 only. The disk drives in the front bay are
capable of supporting software RAID 0, 1, 5, 6, and 10 and hardware RAID 0, 1, 5, and 10.
Compute Tray Rear I/O Panel
Each compute node installs through the rear of the Apollo 480 cabinet. The I/O panels typically provide
COM ports, status LEDs, and Ethernet ports.
Figure 4: Compute Node Rear Panel Example
Cooling System
The hardware architecture of both the compute nodes and the racks provide for optimal front-to-back
cooling. Each compute node has an enclosed fan set. Apollo 480 compute node uses four 40mm fan
assemblies each. A sensor on the main board can increase or decrease the fan speed based on the
ambient conditions. Maximum operational ambient air temperature is +35ºC (95ºF). See the Technical
Specifications for more environmental information.
Optional Hardware
Also, the Apollo 480 enclosure and the compute nodes can include various other hardware components
as part of your Apollo 480 configuration as noted following:
• SATA accessories:
◦ A minimum of one disk drive (per tray) is required for operation
◦ One (1) internal SATA port per compute node
◦ One (1) SATA cable set per compute node
• SAS hard drive options
• One or 2 Gbit Ethernet or (optional) InfiniBand switches
NOTE: Apollo 480 Hadoop clusters do not offer optional InfiniBand connectivity.
Admin Node Server
The HPE DL380 system is a compute-optimized head node server comprised of two main subsystems:
the 2U chassis and a server board (motherboard). Check with your sales or service representative before
loading any operating system on your server not provided by the HPE factory or service organization.

precautions will result in serious injury or death. The high-voltage areas of the system are indicated
with high-voltage warning labels.
CAUTION: Power off the system only after the system software has been shut down in an orderly
manner. If you power off the system before you halt the operating system, data may be corrupted.
8Product Overview
System Operation and Troubleshooting
The first half of this chapter describes the basic steps to get your HPE Apollo 480 Cluster up and running.
Following these steps in the order given will enable you to have the system operational within a minimal
amount of time. The second half of this chapter provides you with some basic troubleshooting advice.
Use these sections to eliminate simple problems or obtain information that may be needed by your
service provider.
Unpacking the System and Choosing an Operating Location
Taking note if it was damaged in any way, inspect the Apollo 480 Cluster shipping crate. If the server itself
shows damage, then file a damage claim with the carrier who delivered it.
When you decide on a suitable location for the system, it must be situated in a clean, dust-free area that
is well ventilated. Avoid areas where heat, electrical noise, and electromagnetic fields are generated. You
will also need it placed near a dedicated, 200-240 Volt, and grounded three-phase power outlet.
The Apollo 480 Cluster is designed to fit into a server room environment. Take care in maintaining the
following operating conditions:
• The system must have a 6 inch (15 cm) minimum top air clearance.
• The system must be protected from harsh environments that produce excessive vibration and heat.
• The system must be kept in a clean, dust-free location to reduce maintenance problems.
• Available power must be rated for large computer operation (four 30 amp sources at 200-240 Volts).
Choosing a Setup Location
When choosing a setup location, observe the following guidelines:
• Leave enough clearance in front of the cabinet for opening the front door completely ~48 inches (1.2
meters).
• Leave sufficient clearance in the back of the cabinet for adequate airflow and ease in servicing.
• High-performance systems are placed in a restricted access location (dedicated equipment rooms,
service closets, or the like).
Cabinet Precautions
Observe the following guidelines:
• Compute enclosures are to be installed in the lowest part of the cabinet possible.
• To maintain proper cooling, always keep the cabinet front door and all panels and components on the
compute trays closed when not servicing.
Compute Enclosure Precautions
Observe the following guidelines:
• Review the electrical and general safety precautions in Overview.
• For extra protection, use a regulating uninterruptible power supply (UPS) to protect the Apollo 480
Cluster power supplies from power surges, voltage spikes and to keep your system operating if there
was a power failure. This UPS is an optional device not provided by HPE with your system.
System Operation and Troubleshooting 9
• Service personnel must always allow the hot-plug disk drives and power supply modules to cool
before touching them. To maintain proper cooling, always keep the cabinet door closed when it is not
being serviced.
• Make sure that all power and data cables are properly connected and not blocking the enclosure
airflow.
Compute Enclosure Operating Considerations
Use the guidelines in the following subsections to properly use and maintain the compute enclosures in
the cabinet.
Ambient Operating Temperature
The ambient operating temperature of the rack environment may be greater than the ambient
temperature of the room. Therefore, consideration must be given to installing the equipment in an
environment compatible with the manufacturer maximum rated ambient temperature, +35ºC (95ºF).
Reduced Airflow
Equipment must be mounted into the cabinet so that the amount of airflow required for safe operation is
not compromised.
Mechanical Loading
Equipment must be mounted into the cabinet so that a hazardous condition does not arise due to uneven
mechanical loading.
Circuit Overloading
Consideration must be given to the connection of the equipment to the power supply circuitry and the
effect that any possible overloading of circuits might have on over-current protection and power supply
wiring. Appropriate considerations of equipment nameplate ratings need to be used when addressing this
concern.
Reliable Ground
A reliable ground for the system must be maintained at all times. To ensure this rule, the rack itself must
be grounded. Particular attention must be given to power supply connections other than the direct
connections to the branch circuit (for example, the use of power strips). All power and data cables must
be routed in such a way that they do not block the airflow generated by the compute fans.
Providing Power
Plug the power cord from the power supply array into a rack power distribution unit (PDU) or high-quality
power source that offers protection from electrical noise and power surges.
For higher availability, it is recommended that you use an optional uninterruptible power supply (UPS)
with the cluster server (not a standard product provided by HPE).
Unlike many rack enclosures, the back of the Apollo 480 Cluster cabinet does not have a master power
switch. The rack individual rear AC breakers must all be switched on prior to booting the system.
Note also that the rack does not have an opening rear door and access is limited.
