2.3 HP ProCurve Gigabit Ethernet Network Switches for SVA
The following branch switch tables are included in this section:
Switch  Network Destination Type Relevant Cabling Table and Notes Back
2824 Admin Root Admin Root Ethernet Switch for Standalone an SVA Cluster Solution TOC
2824 Admin Uplink to Cluster Platform Root Switch In-Band Network Switch for Visualization Building Block Branch Switch in a Modular Solution
It is important to precisely follow the cabling tables. The HP XC operating environment and SVA system software expect nodes and uplinks to be in specific locations. Verify the following connections:
• For a standalone SVA Solution:
Port 22 is reserved for the control node.
InfiniBand interconnects are connected to port 23.
• For uplinks from SVA branch switches to Cluster Platform root switches, use port 22.
• Do not set the uplinks from SVA VBBs to trunking. (See Section 1.3 for more information).
Never use any ports that are indicated in the tables as "reserved".
Interpreting the Port ID Syntax for SVA network
To identify all the potential links, the physical link origins and destinations are assigned a unique name string, called a port identifier, or port ID. Network port ID strings have the following syntaxes:
UVB# -y# -M# [Nzz NIC# -P#]
VBB# -y# -M# [Nzz NIC# -P#]
Ethernet Port ID – Syntax Definitions 
The elements that make up the port ID syntax are defined in Table 2-1.
Typical network port identifiers might include the following:
• VBBA01-AES1-P01
This string indicates port 1 (P01) of an administrative network switch (AES1) that is located in visualization building block (A) 01 (VBBA01). 
• VBB02-N02-NIC1
This string indicates network interface port 1 (NIC1), in compute node 2 (N02), located in visualization building block 2 (VBB02).
