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.

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.

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.
