A.05.70 HP Insight Remote Support Advanced and Remote Device Access Security Overview (October 2011, 5900-1735)

allow for TCP communications for a more reliable transmission of data. Alternate ports may also be
used.
• TCP
Transmission Control Protocol (TCP), or IP protocol 6, is a transport-layer protocol that provides reliable
in-order delivery of data. TCP is described in RFC 793.
• Telnet
Telnet is an application-layer protocol that was developed for providing remote terminal sessions. Some
older storage devices, routers, switches, and other devices will support only telnet for network access.
Although it is insecure, Insight Remote Support Advanced uses this protocol to provide support for these
legacy devices. Telnet does not provide encrypted transport of data and is considered to be an insecure
communication service. Most current operating systems use SSH in place of telnet as the standard
terminal communication protocol. Telnet is described in RFC 854. Telnet has been assigned to TCP port
23, however it may be configured to run on other ports.
• UDP
User Datagram Protocol (UDP), or IP protocol 17, is a transport-layer protocol that does not guarantee
data reliability or ordering the way that TCP does. Avoiding the overhead of checking whether every
packet actually arrived makes UDP faster and more efficient, at least for applications that do not need
guaranteed delivery. It is useful for simple applications that can withstand occasional drops of data. If
data reliability is required over UDP, application-layer protocols are responsible for providing retry
and ordering mechanisms. Examples of application-layer protocols that use UDP are SNMP, NFS V2,
DNS, NTP, and OpenVPN. UDP is described in RFC 768.
2.6 Central Management Server Deployment
HP Systems Insight Manager (HP SIM) is the foundation for HP's unified server-storage management strategy.
It is a multi-platform hardware-level management product that supports HP ProLiant, Integrity and HP 9000
servers, HP StorageWorks MSA, EVA, XP arrays, third-party arrays, HP E-series switches and other HP and
non-HP platforms. HP SIM provides the basic management features of system discovery and identification,
single event view, inventory data collection, and reporting. HP SIM leverages a distributed architecture that
is broken into three types of systems:
• Central Management Server (CMS)
• Managed systems
• WEB Browser clients
The CMS and the managed systems together are called the HP SIM managed domain. The CMS executes
HP SIM software and initiates central operations within the domain. It also maintains a database for the
storage of persistent objects.
The Central Management Server (CMS) is a customer-provided HP ProLiant server running Windows Server
or VMware ESX or ESXi with Windows Server running as a VMware guest. Besides general system
administration, the customer is also responsible for all software installation and security updates. Insight
Remote Support Advanced is supported on Windows Server 2003 (SP1) or higher, Windows Server 2008,
Windows Storage Server 2008 and Windows Server 2008 R2. Microsoft SQL Server 2005 or 2008 and
a supported version of HP SIM are also required. The HP SIM installation will automatically install Microsoft
SQL Server 2008 R2 Express Edition if no other version of SQL Server is already installed. The WEBES
installation automatically installs the PostgreSQL database.
NOTE: WEBES uses PostgreSQL 8.4.1. HP SIM uses Microsoft SQL Server 2008 R2 Express Edition.
PostgreSQL uses port 7950 instead of the default 5432. PostgreSQL settings can be viewed in the file
C:\Program Files\HP\svctools\specific\desta\database\data\postgresql.conf.
Insight Remote Support Advanced serves as a plug-in to HP SIM on the CMS and extends the HP SIM database
with Insight Remote Support Advanced elements. In order to use Insight Remote Support Advanced with HP
SIM, the CMS must be a supported HP ProLiant server running a supported version of Microsoft Windows
Server.
