2 Overview The HP 3PAR Service Processor (SP) is available in both physical and virtual versions for the SP 4.1.0 release. The SP is designed to provide remote error detection and reporting and to support diagnostic and maintenance activities involving the storage systems. The SP is composed of a Linux operating system and the SP software, and it exists as a single undivided entity. The physical SP is a hardware device mounted in the system's rack. If the customer chooses a physical SP, each storage system installed at the operating site includes a physical SP installed in the same cabinet as the system's controller nodes. A physical SP uses two physical network connections; one (eth0) requires a connection from the customer network in order to communicate with the StoreServ Storage system. The other (eth1) is for maintenance purposes only and is not connected to the customer network. The virtual SP is provided in an Open Virtual Format (OVF) format. Virtual SP is tested and supported on the VMware vSphere Hypervisor (based on ESXi 4.0 server and supported on ESXi 4.1 and 5.x clients). The virtual SP has no physical connections. It runs on a customer-owned and customer-defined server and communicates with an HP 3PAR StoreServ Storage System over its own Ethernet connections. For information about how to deploy the virtual SP, see "Deploying the Virtual SP" (page 38). The virtual SP is supported only for the HP 3PAR StoreServ 7000 Storage System. Service Processor Connectivity Overview The data collected by the SP is used to maintain, troubleshoot, and upgrade the SP and the HP 3PAR StoreServ Storage system. (Only one storage system can be attached to a Service Processor.) Depending on the SP's connection mode, the SP communicates either with an HP 3PAR Connection Portal or with the HP 3PAR Collector Server. During the system setup, the SP can be set up in either Secure Network mode (recommended) or SP mode. In Secure Network mode, the SP communicates with the HP 3PAR Collector server using HP 3PAR Secure Service Agent software. In SP mode, the SP communicates with the HP 3PAR connection portal server via SSH and SFTP. The connection between the SP and the connection portal can be made using your network and the Internet or a point-to-point connection with a modem. Connections that use your network pass through your firewall while connections that use a modem bypass the firewall. NOTE: Modem support is discontinued in the HP 3PAR Service Processor 4.1.0 release. Customers planning to upgrade to HP 3PAR OS 3.1.2 (which requires SP 4.1.0) will need to move to a supported connectivity model. The HP 3PAR Secure Service Agent (SSA) enables the SP to communicate with the Collector server. Unlike direct SSH connections to your SP, with the SSA it is not necessary to open additional ports on your firewall, because communications are performed with HTTPS. Secure Network mode and SP mode are discussed further in the following sections. Secure Network Mode Overview In Secure Network mode, the SP communicates with the HP 3PAR Collector Server using the HP 3PAR Secure Service Agent (SSA). Like the Connex server, the Collector server provides software updates, access to service tools applications such as Service Processor Onsite Customer Care (SPOCC), and access to resources such as Business Services Center (BSC). 6 Overview

2 Overview
The HP 3PAR Service Processor (SP) is available in both physical and virtual versions for the SP
4.1.0 release. The SP is designed to provide remote error detection and reporting and to support
diagnostic and maintenance activities involving the storage systems. The SP is composed of a Linux
operating system and the SP software, and it exists as a single undivided entity.
The physical SP is a hardware device mounted in the system’s rack. If the customer chooses a
physical SP, each storage system installed at the operating site includes a physical SP installed in
the same cabinet as the system’s controller nodes. A physical SP uses two physical network
connections; one (eth0) requires a connection from the customer network in order to communicate
with the StoreServ Storage system. The other (eth1) is for maintenance purposes only and is not
connected to the customer network.
The virtual SP is provided in an Open Virtual Format (OVF) format. Virtual SP is tested and supported
on the VMware vSphere Hypervisor (based on ESXi 4.0 server and supported on ESXi 4.1 and
5.x clients). The virtual SP has no physical connections. It runs on a customer-owned and
customer-defined server and communicates with an HP 3PAR StoreServ Storage System over its
own Ethernet connections.
For information about how to deploy the virtual SP, see
“Deploying the Virtual SP” (page 38)
. The
virtual SP is supported only for the HP 3PAR StoreServ 7000 Storage System.
Service Processor Connectivity Overview
The data collected by the SP is used to maintain, troubleshoot, and upgrade the SP and the HP
3PAR StoreServ Storage system. (Only one storage system can be attached to a Service Processor.)
Depending on the SP’s connection mode, the SP communicates either with an HP 3PAR Connection
Portal or with the HP 3PAR Collector Server.
During the system setup, the SP can be set up in either Secure Network mode (recommended) or
SP mode. In Secure Network mode, the SP communicates with the HP 3PAR Collector server using
HP 3PAR Secure Service Agent software. In SP mode, the SP communicates with the HP 3PAR
connection portal server via SSH and SFTP.
The connection between the SP and the connection portal can be made using your network and
the Internet or a point-to-point connection with a modem. Connections that use your network pass
through your firewall while connections that use a modem bypass the firewall.
NOTE:
Modem support is discontinued in the HP 3PAR Service Processor 4.1.0 release. Customers
planning to upgrade to HP 3PAR OS 3.1.2 (which requires SP 4.1.0) will need to move to a
supported connectivity model.
The HP 3PAR Secure Service Agent (SSA) enables the SP to communicate with the Collector server.
Unlike direct SSH connections to your SP, with the SSA it is not necessary to open additional ports
on your firewall, because communications are performed with HTTPS.
Secure Network mode and SP mode are discussed further in the following sections.
Secure Network Mode Overview
In Secure Network mode, the SP communicates with the HP 3PAR Collector Server using the HP
3PAR Secure Service Agent (SSA). Like the Connex server, the Collector server provides software
updates, access to service tools applications such as Service Processor Onsite Customer Care
(SPOCC), and access to resources such as Business Services Center (BSC).
