Preface
Using this Guide
This guide is comprised of nine chapters covering both general information and reference tables.
Readers new to the HP Medical Archive system should read the first
four chapters to gain an understanding of how the NMS works to help
you monitor the grid. The first two chapters introduce the basic functionality and interface layout of the NMS. The next two chapters
explain NMS functionality for understanding alarm monitoring and
notifications, and for obtaining reports.
The remaining chapters provide references to look up specific information. Chapters 5 and 6 provide reference information on services
and components. Chapter 7 is the final chapter on the NMS; a reference of alarms with troubleshooting tips.
The last two chapters deal with the Server Manager application used
on the HP Medical Archive cabinet console(s).

enhance readability and usefulness of the text.
Terminology
There is some room for confusion between common computer
network terminology for “server” and “node” as they are used in this
document.
A server is usually thought of as a piece of computing hardware that
provides data services to requesting network clients; a resource pro-

viding network, computational, and storage services. Within the
context of the HP Medical Archive, a server is a piece of hardw are that
hosts one or more grid services.
Nodes in a network are usually defined as an independent entity with
a unique network identity, running on a resource. In this text, the use
of the term “node” refers to the logical entity of a building block
within the HP Medical Archive; it is a server combined with a predefined set of grid services that perform one or more tasks within the
grid.
The term “node” also appears within the NMS interface. In that
context, it generally refers to a single grid service, regardless of how
many services may be hosted on the server. See “Network and

Architecture Overview
The HP Medical Archive architecture provides a secure, reliable, and
high performance solution for the storage and distribution of very
high volumes of fixed content health care data within a data center
and optionally a disaster recovery (DR) site.
The term “grid computing” is inspired by the success of the interconnection of the electric power and communication network
infrastructure in the late 1800s and early 1900s.
The power grid manages the available power resources and balances
loads to ensure continuous operation. How and where the power originates is transparent to the consumer. During peak hours, available
resources are automatically balanced and power is rerouted to where
it is needed most. As demand increases, additional generating
resources come online, and they are transparently utilized. Similarly,
when stations go offline or get decommissioned, there are no
consumer service disruptions. The grid automatically balances the
available resources to changing demand; loss of a subset of resources
does not result in degraded service.
Grid computing is based on the principle that access to computational
resources (storage, processing power, and data) can be enhanced with
high levels of reliability and scalability, analogous to obtaining electric
power from the power grid. Grid storage is the application of grid
computing principles to storage architecture: directories, query,
resource management, and fault management.
The HP Medical Archive system is composed of multiple nodes, which
form a unified archive. Each node consists of software services operating on a server that manages a limited capacity storage resource.
Within a given facility, all nodes are interconnected using standard
TCP/IP networking, and communicate with local imaging modalities,
PACS, and workstations. Wi de Area Network (WAN) links extend the
grid, enabling off-site replication of content for disaster recovery.
The HP Medical Archive deployment relies on open standards for
interoperability with external hospital systems. Exchange of clinical
data with external clinical systems, including PACS, viewing workstations, and modalities, takes place over standardized network file
system protocols (NFS/CIFS) or (optionally) via established imaging
protocols, including DICOM.

Role of the Network Management System (NMS)
The Network Management Syste m (NMS) performs two primary functions for HP Medical Archive deployments:
• It is a monitoring system that notifies administrators of problems
when the status of key hardware or software changes (including
via e-mail or mobile phone text message, if configured).
• It is a browser-based interface making the system easily available
to multiple users for:
• Reporting status information about the grid’s hardware and
software so you can monitor and resolve grid issues.
• Creating, viewing, and printing reports on current and historic
data about each grid component based on your selection of
report criteria.
• Configuring grid components and customizing the notification
settings according to your criteria.
Getting Started
Network and Element Terminology
The Network Management System views the HP Medical Archive
system as having tiers, or layers of detail. From the highest (big
picture) to the lowest (most granular detail) the elements are:
• Locations
• Nodes
• Services
• Components
• Attributes
Locations
The location tier views the grid as being made up of geographically
separate facilities or groups of nodes. The HP Medical Archive can be
deployed as a Single Site (Site A) or Single Site + DR (Site A and Site B).
Nodes
Within the context of the HP Medical Archive system, a node is a
server hosting a collection of one or more grid services. Physically, a
server is a computer with associated storage and network resources.
Logically, a node hosts services that the NMS can monitor and
manage. (The NMS itself is a service that runs on one or more servers.)
HP Medical Archive 3
T4434-96001
HPMA User Guide
Services
A service is a software module providing a set of capabilities to the HP
Medical Archive system. They are discussed in detail in Chapter 5.
Each service consists of components that deliver a particular capability. Each node of the grid has a predefined set of services that it hosts.
Services are typically identified by a three letter acronym.
Components
A component within a service delivers a particular capability. Each
component has a set of configurable attributes that can be monitored
automatically.
Services contain one or more components. Each component contains a
set of attributes.
Capabilities
Components have names defined by the software.
Attributes
The most granular level of the system is an attribute. This is a single
value or property of a component in a service. Attributes are the
elements that are monitored for alarm states and may be included in
reports.
Every component contains a set of attributes associated with the capability it enables.
For each service and component the NMS interface presents four tabs,
one for each capability:
• Overview—property information about the service or component.
You can use this capability to trace alarms, generate immediate
reports (page 43), and get an overall sense of a service or component’s performance.
• Alarms—showing the status of monitored attributes and reporting
alarm histories, enabling you to trace and troubleshoot current
alarms and analyze alarm histories to prevent future problems.
• Reports—for generating reports on current and historical condi-
tions of attributes to monitor and improve system performance.
4 HP Medical Archive
T4434-96001
• Configuration—to set or change service settings or alarm monitor-
ing conditions.
Consult the specific service descriptions in Chapter 5 for details of the
exact information and Chapter 6 for settings available.
Software Requirements
Accessing the NMS requires access to a web browser with grid access
to a well-known address (defined by your system administrator).
At this time, the only supported browser is:
• Microsoft Internet Explorer v6.0 SP2 (and above)
• JavaScript and cookies must be enabled
To view the customized and dynamic graphics used by the NMS, you
must also download and install:
• Adobe SVG Viewer plug-in
The plug-in is available from the Adobe web site:
www.adobe.com/svg/viewer/install/
Getting Started
This viewer supports Scalable Vector Graphic technology (SVG); a
powerful tool used for high quality graphics that are dynamically
created from real-time data.
Accessing the NMS
The Network Management System (NMS) can be accessed using a
supported web browser (page 5).
Both the user name
and password are
case sensitive.
You require a user name and password to access the system. Each
system user is assigned their user name and password when first
introduced to the NMS. If you did not receive a user name and password, contact your system administrator. (See “Managing User
Accounts” on page 8 for more information.) To connect to the NMS
interface:
1. Launch the Internet Explorer browser.
2. Open the address: https://<IP_Address>:8443/NMS where
<IP_Address> is the address of the Admin Node.
