System Overview

The HP StorageWorks NAS server can be used in many types of computing environments,
from basic Microsoft Windows workgroups to complicated multiprotocol domains using DFS,
NFS, FTP, HTTP, and Microsoft SMB. The corresponding varieties of clients that can be
serviced include any Windows, UNIX, Linux, Novell, or Macintosh variant.

This chapter provides an overview of these environments and deployments and includes brief
descriptions of system user interfaces, applications, and options.

Product Definition and Information

The business class NAS 4000s and the enterprise class NAS 9000s are solutions that provide
reliable performance, manageability, and continuous data availability through the fusion of
Network Attached Storage (NAS) and Storage Area Network (SAN) technologies.

Server Hardware and Software Features

Refer to the HP StorageWorks NAS 4000s/9000s Installation Guide for a listing of server
hardware and software features.

For specific software product recommendations, go to the HP website:

http://www .hp.com/go/nas

Product Manageability

The NAS server ships with the following utilities and features that ease the administration
tasks associated with managing the system:

■ The Rapid Startup Wizard is a user friendly configuration utility that ensures easy

configuration.

■ The WebUI is a simple, graphical user interface (GUI) that helps with administration

tasks.

■ Insight Manager is a comprehensive tool designed to be a key component in the systems

■ The Integrated Lights-Out feature provides remote access, sends alerts, and performs other

Product Redundancy

The NAS server is specifically designed to perform file serving tasks for networks. Using
industry standard components, redundancy of power supplies, NICs, and fans ensures
reliability.

The clustering ability of the NAS device further ensures continuous data availability, because
data being processed by one server transitions over to the other server in a failover situation.

Other industry standard features, such as redundant array of independent drives (RAID) and
remote manageability, further enhance the overall dependability of the NAS server.

The server contains dual 36.4 GB hard drives preconfigured with the NAS operating system so
that the active system volume is mirrored (RAID 1+0) to the second drive. If one of the
internal drives fails, the integrity of the system is preserved, because the system will use the
copy of the operating system on the remaining healthy drive. The drives in the server are
hot-pluggable, so the failed drive can be replaced while the system is running. When the failed
drive is replaced, the system automatically uses the version of the operating system on the
healthy drive to rebuild the replacement.

management environment. It monitors the operations of HP servers, workstations, and
clients. Insight Manager provides system administrators more control through
comprehensive fault and configuration management, and industry leading remote
management.

management functions, even if the operating system of the host server is not responding.

The NAS server includes dual power supplies. A power supply can be replaced while the
server is running. To ensure redundancy, it is important to connect each power supply to a
separate power source. If one power source fails, the server remains operational through the
second power source.

Through a seamless, hardware-based, graphical remote console, the Integrated Lights-Out port
provides the administrator with full control of the server from a remote location. Using a client
browser, the administrator can remotely power up, power down, and operate the console. A
built in processor makes the port independent of the server and the operating system.

20 NAS 4000s and 9000s Administration Guide

Deployment Scenarios

Various deployment scenarios are possible. Typical application of NAS devices include:

■ File server consolidation

As businesses continue to expand their information technology (IT) infrastructures, they
must find ways to manage larger environments without a corresponding increase in IT
staff. Consolidating many servers into a single NAS device decreases the number of points
of administration and increases the availability and flexibility of storage space.

■ Multiprotocol environments

Some businesses require several types of computing systems to accomplish various tasks.
The multiprotocol support of the NAS server allows it to support many types of client
computers concurrently.

■ Protocol and platform transitions

When a transition between platforms is being planned, the ability of the NAS server to
support most file sharing protocols allows companies to continue to invest in file storage
space without concerns about obsolescence. For example, an administrator planning a
future transition from Windows to Linux can deploy the NAS server with confidence that
it can support both CIFS and NFS simultaneously, assuring not only a smooth transition,
but also a firm protection of their investment.

System Overview

■ Remote office deployment

Frequently, branch offices and other remote locations lack dedicated IT staff members. An
administrator located in a central location can use the WebUI of the NAS server, Microsoft
Terminal Services, and other remote administration methods to configure and administer
all aspects of the NAS server.

Configuration Options for the NAS Server

The NAS server can be deployed in two different configurations attached to a storage area
network (SAN): as a single NAS device or as a clustered pair. By default, the NAS server does
not ship with a standard HBA to allow for maximum flexibility in the SAN environment. For a
list of supported HBAs for the NAS servers, see the quick specs for the product.

21NAS 4000s and 9000s Administration Guide

System Overview

NAS Server as a Single Device

In the single NAS device configuration, a NAS server is attached to a SAN via a single or pair
of fiber channel host bus adapters (HBAs) and one or more SAN switches. In Figure 1, the
dual HBA approach is illustrated. Each HBA should be connected to a separate switch that has
access to the same controller pairs. This connection method allows redundant paths to the
same storage subsystem. Dual HBAs per NAS device is recommended but not required for
stand alone deployments, since dual HBAs allow for path failure while still providing access to
the data.

SAN storage is not managed by the NAS server and requires coordination between the NAS
administrator and the SAN administrator. LUN requests need to be made and assigned to the
NAS server using selective storage presentation from the SAN controller pairs. Naming of the
LUNs and the connections to the NAS server is important for tracking and identification
purposes. At least one LUN is required by the NAS server for the device to be functional.

NAS Server as a Clustered Pair

In the clustered configuration, two NAS devices are linked via a private network and have
access to shared storage as illustrated in Figure 2. In clustered deployments, it is recommended
that each NAS device be attached to the SAN via a pair of fiber channel HBAs. Dual HBAs per
NAS device is recommended but not required for cluster deployments, since dual HBAs allow
for path failure without causing node failover in the cluster.

For the NAS server, cluster setup requires at least three LUNs. One LUN is required for the
quorum disk and two LUNs are required for data disks. Individual data disks specific to each
node are required for the proper setup of file sharing where both nodes participate in
file-sharing activities. Clustered NAS systems have the ability to provide redundant
active/active access to file shares on disk. However, as with all Microsoft-based clusters, the
unit of ownership among nodes is at the disk level. Therefore, individual fileshares can be
accessed by only one node at a time based on which node owns the disk.

Multi Node Support Beyond Two Nodes

The NAS 4000s and 9000s devices may be deployed in multi node clustering beyond two
nodes. Refer to the associated Storage Array documentation to determine the number of nodes
supported by the array under Windows Storage Server 2003. While the discussion presented in
this guide addresses only two nodes, additional nodes may be added into the cluster.
Considerations for additional fiber path connections and the private network should be made.
In the case of the private network, a hub or switch is required since the cross over cable is no
longer applicable.

Connecting NAS Servers to the Network

The NAS server can be connected to the network as a single device or as a clustered pair.

23NAS 4000s and 9000s Administration Guide

System Overview

NAS Server Single Device Deployment

In a single device deployment, network connections are divided into two categories: client data
segments and management segments. The default shipping configuration contains a two-port
network interface controller (NIC) 10/100/100 that provides one port for management and one
port for client data. The management port is intended for use with the 3202 port of the device
to enable use of the WebUI that accompanies the product. It is from this WebUI that most
management and administrative procedures can be accomplished. An additional management
port for remote console and diagnostics is provided off the Integrated Lights-Out (iLO) port.
HP recommends that this connection be placed on a management LAN separate from the
corporate infrastructure.

The NAS server supports the use of NIC teaming. NIC teaming provides failover and load
balancing of network ports of the NAS server. NIC teaming requires the network cables to be
installed on the same subnet to enable it to work. For example in Figure 3, Eth1 and Eth2
would need to be on the same subnet to enable this functionality on those ports. However, it is
not recommended to assign IP addresses to the ports that will be teamed or load balanced prior
to the installation and setup of NIC teaming. For this reason, HP recommends that you set all
network ports to DHCP. For information concerning the configuration of NIC teaming after
setup is complete, see Chapter 2.

NAS Server Cluster Deployment

In a clustered deployment, network connections are divided into three categories: cluster
maintenance segments, client data segments, and management segments. The default shipping
configuration contains a two-port 10/100/1000 NIC that together provide one port for the
cluster maintenance and one port for management and client data. An additional management
port for remote console and diagnostics is provided off of the iLO port. HP recommends that
this connection be placed on a management LAN separate from the corporate infrastructure.

The cluster maintenance segment is also known as the heartbeat connection between the
nodes. In standard configurations, this connectivity is obtained by the use of a crossover
network cable. The same effect can be achieved by placing the heartbeat ports on its own
switch or VLAN, as illustrated in Figure 4 as Eth1. The purpose is to isolate and guarantee the
connectivity between the nodes without interruption. If interruption occurs, the remaining
cluster node will assume the other node has gone down and initiate a failover. A second cluster
heartbeat path is often recommended as a redundant path. The redundant path is often done
over one of the remaining network segments and is not dedicated.

The client data segments of a cluster must reside on identical network segments for each node.
As illustrated in Figure 4, Eth2 from both nodes is shown on the same segment. This
co-location on the same segment allows cluster resources such as file shares to failover to the
second node and continues to provide availability to the resources. The failed resource will
have the same IP address after the failover and therefore must have a port corresponding to the
identified subnet of the IP address present on both nodes.

The NAS server supports the use of NIC teaming in clustered configurations. All previous
caveats from the “NAS server single node deployment” on networks section still apply.

System Overview

Environment Scenarios

The NAS server is deployed in one of two security modes:

■ Workg rou p

■ Domain (Windows NT Domain or Active Directory Domain)

The NAS server uses standard Windows user and group administration methods in each of
these environments. For procedural instructions on managing users and groups, see Chapter 6
of this guide.

Regardless of the deployment, the NAS server integrates easily into multiprotocol
environments, supporting a wide variety of clients. The following protocols are supported:

■ Distributed File System (DFS)

■ Network File System (NFS)

■ Hypertext Transfer Protocol (HTTP)

■ File Transfer Protocol (FTP)

■ Microsoft Server Message Block (SMB)

Workgroup

Domain

In a workgroup environment, users and groups are stored and managed separately, on each
member server of the workgroup. Workgroups are typical for very small deployments where
little or no computing environment planning is required.

Note: In a clustered deployment, the clusters must be members of a domain. Therefore, workgroup

environments are supported only in non-clustered deployments.

When operating in a Windows NT or Active Directory domain environment, the NAS server is
a member of the domain and the domain controller is the repository of all account information.
Client machines are also members of the domain and users log on to the domain through their
Windows based client machines. The domain controller also administers user accounts and
appropriate access levels to resources that are a part of the domain. Additional information
about planning for domain environments can be found at:

http://www.microsoft.com/windowsse rver2003/technologies/directory/activedirectory/default .mspx

The NAS server obtains user account information from the domain controller when deployed
in a domain environment. The NAS server itself cannot act as a domain controller, backup
domain controller, or the root of an Active Directory tree as these functions are disabled in the
operating system.

User Interfaces

There are several user interfaces that administrators can use to access and manage the NAS
server. Two of these interfaces are:

■ NAS server WebUI

■ NAS server Desktop

Each interface contains the same or similar capabilities, but presents them in a different
manner. Each of these interfaces are illustrated in the following sections.

NAS Server Web-Based User Interface

The WebUI provides for system administration, including user and group management, share
management, and local storage management.

Refer to the HP StorageWorks NAS 4000s/9000s Installation Guide for detailed information
on using the Rapid Startup Wizard for initial setup.

To access the WebUI, launch a Web browser and enter the following in the address field:

https://<your NAS machine name or IP Address>:3202/

The default user name is Administrator. The default password is hpinvent. Online
help for the WebUI is available by clicking the Help tab on the primary WebUI screen.

The primary screen of the WebUI is shown in Figure 5.
