2.2 Service Processor Connectivity
3PAR Service Processor User’s Guide
The InServ Storage Server Service Processor (SP) is a hardware device mounted in the storage
server rack. It is designed to provide remote error detection and reporting, and to support
diagnostic and maintenance activities involving InServs. In general, only one SP is required per
operating site. However, additional SPs might be required depending on the number of
storage servers and the customer network topology.
The first storage server installed at the operating site includes an SP installed in the same
cabinet as the storage server controller nodes.
2.1 Service Processor Connectivity
The data collected by the Service Processor (SP) is used to maintain, troubleshoot, and upgrade
the SP and storages servers at the operating site. Depending on the SP’s connection mode, the
SP either communicates with a 3PAR Connection Portal or with the 3PAR Collector server.
During storage server setup, the SP can be setup in either SP mode or Secure Network mode. In
SP mode, the SP communicates with the 3PAR Connex server via a connection portal. In Secure
Network mode, the SP communicates with the 3PAR Collector server using 3PAR Secure Service
Agent software.
The connection between the SP and the connection portal can be made using either 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.
The 3PAR Secure Service Agent (SSA) is a server-based software feature that 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 since communications are
performed with HTTPS.
SP mode and Secure Network mode are discussed further in the following sections.
2.2 About SP Mode
SP mode enables communication between an SP and the 3PAR Connex server located at 3PAR
Central using a connection portal. The Connex server provides software updates, Service
Processor Onsite Customer Care (SPOCC) service tools applications, and access to resources such
as the Document Control System (DCS). In SP mode, the Service Processor (SP) and any
connected InServ Storage Servers are supported and maintainted using the SPMAINT utility.
