HP Cluster Platform Server and Workstation Overview

Table 1-13 HP Integrity rx4640 Ports Used in Clusters
Cluster Cabling Name and DescriptionPort LabelCallout
When used as a control node only, both power supplies are used to provide
redundancy. Otherwise, utility nodes use only PWR 0.
PWR 0 and PWR 11
VGA Video Port. When used as a control node, this port is optionally connected
to the cluster's KVM console.
Screen Icon2
When this server is used as a control node, use only the top USB port for the
optional connection to the KVM mouse and keyboard. Do not use the ports labeled
keyboard and mouse.
USB ports3
MP (Console, CES). The MP Ethernet LAN connection. This 10/100 Base-T port is
connected to the root console switch (CES1) in the UBB.
MP LAN4
NIC1 (Administrative, AES) – The Gigabit Ethernet Port in PCI slot 2. This
10/100/1000 Base-T Ethernet port is connected to the root administrative switch
(AES1) in the UBB.
LAN Gb5
PCI (slot 8).N/A6
The spare Ethernet port in PCI slot 2 is designated NIC 2 and might also be used for an optional
connection to the site WAN, depending on the server's role.
Refer to the server documentation for definitions of the remaining ports, but be aware that you
should never make additional connections to a server that is configured for a specific role in the
cluster.
1.6.1 Supported Memory Configurations
The HP Cluster Platform does not enforce any memory configuration rules on the control node
and utility nodes other than those associated with the server used. You can use DIMMs of 256
MB, 512 MB, 1 GB, and 2 GB providing you follow the upgrade rules for mixed DIMMs. For the
HP Integrity rx4640 these rules are:
• The HP Integrity rx4640 has a 16-DIMM memory extender board that is minimally configured
with 1 GB of memory, four 256 MB DIMMs loaded in quad 0 (slots 0A, 0B, 0C, and 0D).
• An optional 32 DIMM memory extender board is available to replace the 16-DIMM memory
extender board. Configure the extender board with a minimum of 1 GB in quad 0.
• Install additional DIMMs into both 16 and 32 DIMM boards. When adding DIMMs, use a
minimum of four DIMMs of identical size, and install them in the next available quad.
• You can use DIMMs of varying size across the entire extender board, but all four DIMMs
in each quad must be of an identical size.
• Remove slot fillers only to add DIMMs. Do not leave any empty slots without a filler because
this can affect system cooling.
