HP Instant Support Enterprise Edition (ISEE) provides proactive remote monitoring, diagnostics,
and troubleshooting to help you enhance the availability of your servers, as well as
storage and network devices. The ISEE software is located on the storage server in the
HPProLiantML350G5StorageServer 13

c:\hpnas\components\ISEE folder. For more information, go to the HP web site:
http://h20219.www2.hp.com/services/cache/10707-0-0-225-121.aspx.
HP Services provides service tools that notify you when a significant system event has or will occur. These
tools, WEBES System Event Analyzer (SEA) and OSEM, are used both as part of the ISEE remote service
offering and as standalone tools to HP service customers. They are designed to send a notification
only when an event or series of events has occurred that require service action. They are not intended
to be real-time system state monitors that trigger with every event. Most system components have the
capability of sending hundreds of state events during normal operation. SEA and OSEM are designed
to filter these component events and only notify customers and/or HP Services when action needs to
be taken to resolve or prevent an outage. As designed they will not report all events. Other utilities
are available to monitor real time system state. The software is located on the storage server in the
c:\hpnas\components\ISEE\OSEM and c:\hpnas\components\ISEE\WEBES folders.

14 About this guide

1TheHPstorageserversolution
This chapter describes some basic storage technologies along with the underlying software components
that comprise an HP ProLiant Storage Server.
The HP ProLiant Storage Server products can be used in many types of computing environments, from
basic Microsoft®Windows®workgroups to complicated multiprotocol domains using Distributed File
System (DFS), Network File System (NFS), File Transfer Protocol (FTP), Hypertext Transfer Protocol (HTTP),
and Microsoft Server Message Block (SMB). The corresponding varieties of clients that can be serviced
include any Windows, UNIX®,Linux,Novell,orMacintoshvariant.
The HP ProLiant Storage Server family of products includes enterprise class, as well as remote office or
small to medium business class solutions that provide reliable performance, manageability, and fault
tolerance. Each HP ProLiant Storage Server has been specifically designed to function as a network
attached storage server. Refer to the HP ProLiant Storage Server QuickSpecs (available on the HP web
site http://www.hp.com/go/storage) for a list of server hardware and software features. Click NAS,
select a storage server, and then select a link for the QuickSpecs.
Server identification
The model identifiers of ProLiant Storage Servers have a prefix of DL or ML. DL is the optimized density
line, and is mounted into a rack. ML is the maximized configuration line, and considered to be a
desktop server. The number following the prefix increases with the amount of features and capability. For
example, the 100 series generally has fewer features than the 300 or 500 series storage servers. Each
major revision to the server is designated by a generation (G) designation. For example the DL100 G2 is
a rack-mounted, second-generation, 100-series server.
The storage environment
Servers play an important role in the storage environment. They can connect into a storage area network
(SAN) infrastructure with cabling, hardware, and software, to manage the data flows moving in and out.
This section describes some of the technology involved in the storage environment.
SAN
A SAN is a specialized, dedicated high-speed network. Servers and storage devices may attach to the
SAN. It is sometimes called “the network behind servers.” Like a local area network (LAN), a SAN
allows an “any to any” connection across the network using interconnect elements such as routers,
gateways, hubs, and switches. Fibre Channel is the standard SAN networking architecture, although
other network standards could be used. A decision to implement a SAN is usually a decision to develop
anewstorage network infrastructure.
NAS
Storage devices which optimize the concept of filesharingacrossthenetworkhavecometobeknown
as network attached storage (NAS). NAS solutions use the mature TCP/IP network technology of the
Ethernet LAN. Data is sent to and from NAS devices over the LAN using the TCP/IP protocol. By making
storage devices LAN addressable, the storage is freed from its direct attachment to a specificserver,and
any-to-any connectivity is facilitated using the LAN fabric.
In principle, any user running any operating system can access files on the remote storage device. This
is done by means of a common network access protocol. In addition, a task, such as backup to tape,
can be performed across the LAN using specialized software, enabling sharing of expensive hardware
resources, such as automated tape libraries, between multiple servers.

Fibre Channel technology
Fibre Channel technology provides low latency and high throughput capabilities. It uses either a serial
copper or fiber optic link to connect the server with storage devices. Fiber optic technology allows for
storagetobel
ocated a maximum distance of up to 10 kilometers away from the attaching server. The
significant advantage of Fibre Channel is its ability to connect redundant paths between storage and
servers. In addition, Fibre Channel offers improved scalability due to several connection topologies.
Basic point-to-point connections and loop and switch are topologies that add to the flexibility of server
and storage connections. For many enterprise environments, Fibre Channel is the technology serving
high-performance and mission-critical applications.
Serial ATA technology
Serial Advanced Technology Attachment (SATA) offers increased data rate performance over its parallel
equivalent, EIDE, or also known as ATA. SATA transmits its signals serially compared to the multiple
streams found in parallel technology. It moves data faster than parallel technology because it is not tied to
a particular clock speed. Besides improving performance, it was designed to overcome the master/slave
configuration and maximum cable length limitations of parallel ATA technologies, while maintaining cost
efficiency. SATA allows for hot-swappable drives, lowering system down time risks. SATA is an ideal
solution for secondary storage in networked storage environments. It is not an appropriate solution
for storage environments serving enterprise applications requiring high performance, mission-critical,
and production environments.
Serial ATA versus SCSI and Fibre Channel disks
SCSI disk technology is the right choice for entry-level networked storage, as it offers the same advantages
that Fibre Channel disks provide for large enterprise disk arrays. In addition, it offers a simple migration
path from servers to SAN called direct attached storage (DAS) to SAN. The introduction of Serial ATA
technology offers a new way of storing data. Derived from the storage used in desktop PCs, its cheaper
components provide a much lower cost per megabyte than SCSI or Fibre Channel disks. However, as
acon
sequence, its levels of performance and reliability are also lower. That said, Serial ATA is not
intended as a replacement technology. SCSI and Fibre Channel remain better choices for reliable,
high-performance application serving and storage. However, if you want cost-effective storage for
infrequently accessed data—such as data repositories or reference information—then Serial ATA is
a good choice.
Tiered storage environments
In a tiered storage environment, you can match your data to storage that has an appropriate level of
performance and availability—giving you a lower cost of ownership without any negative impact on your
business. Here’s how it could work in a typical disk-to-disk-to-tape environment:
•Data with the highest requirements is stored in the first tier, on the SCSI or Fibre Channel disks.
•The second tier stores near-online or infrequently accessed data (such as disk-to-disk backup
copies) on Serial ATA disks.
•The third tier comprises tape-based backup copies or data archived on optical media.

iSCSI technology
The iSCSI protocol defines the rules and processes for transporting SCSI (block-level) data over a TCP/IP
network. The iSCSI standard follows the SCSI architectural model, which is based on message exchange
between an initiator and a target. In the SCSI model, initiators and targets are identified by a unique
SCSI device name. Because iSCSI transport occurs over a network fabric instead of a direct cable
connection, the initiator and target have multiple IP addresses associated with their iSCSI names.
The following is an example of what occurs during a message exchange between an initiator and
a target. The process begins when an application sends a request to the operating system (OS) to
read or write data. The OS generates the appropriate SCSI commands and data request in the form
of a message. Before the message can be sent over an IP network, it is processed through iSCSI to
encapsulate the request into the TCP/IP protocol stack (attaching routing, error checking, and control
information) for transmission over the network. This can be accomplished using driver- or OS-level
software, or it can be offloaded to the host bus adapter (HBA). The HBA transmits the packets over the IP
network. When the packets reach the target device, they go through a reverse process to reassemble
(sequence) the data, which is then moved to the SCSI controller. The SCSI controller fulfills the request by
writing data to, or reading data from, the target device. If it is a read transaction, the target returns data
to the initiator using the iSCSI protocol.

Windows Storage Server 2003 R2 editions
Windows Storage Server 2003 R2 is a dedicated file and print server application based on Windows
Server 2003, with dependability and seamless integration in networked storage. Windows Storage
Server 2003 R2 integrates with existing infrastructures and supports heterogeneous file serving as
well as backup and replication of stored data. Windows Storage Server is also an ideal solution for
consolidating multiple file servers into a single solution that enables cost reduction and policy-based
management of storage resources. Windows Storage Server 2003 R2 includes advanced availability
features such as point-in-time data copies, replication, and server clustering. Because Windows Storage
Server 2003 R2 solutions are preconfigured, they can be deployed out of the box in a short time, and the
HP Storage Server Management Console makes management easy. Windows Storage Server 2003
R2 integrates with existing infrastructures, so enterprises can make full use of commonly-used network
HPProLiantML350G5StorageServer 17

environments and standard management software, as well as the Active Directory service. Preconfigured
Windows Storage Server 2003 R2 solutions are available from original equipment manufacturers (OEMs)
in sizes ranging from a few hundred gigabytes (GBs) to several terabytes (TBs).
Three editions of the Windows Storage Server 2003 R2 operating system are offered with ProLiant
Storage Servers:
•Workgroup
•Standard

Storage server roles
There are two primary roles that a ProLiant Storage Server can perform in your environment.
•File server
•Print server
File server
Afile server is a NAS solution that provides easy-to-use, rapidly deployable network storage with
multi-protocol file sharing and print serving services. The file server comes pre-installed with the Microsoft
Windows Storage Server 2003 R2 operating system and storage-specific management tools.
Thefollowingarescenarioswhereafile server can be deployed:
•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 file server 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 file 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 file 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 file 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.
•Remote office deployment
Frequently, branch offices and other remote locations lack dedicated IT staff members. An
administrator located in a central location can use remote administration methods of the storage
server or Microsoft Terminal Services to configure and administer all aspects of the storage server.
Printserver
A print serving solution provides network printing, print driver distribution, and print management. The
print server may be used in a secondary role for multiprotocol file sharing services with limited scalability
of storage. The print server comes preinstalled with the Microsoft Windows Storage Server 2003 R2
operating system and easy to use print specific management tools.
Thefollowingarepossibleusescenariosforaprintserver:
•Quick and easy way to add print capacity without affecting the general purpose server.
•With a host network printer management application (for example, Microsoft PMC or HP Web
JetAdmin)
•Network printing services for a variety of client operating systems:
•Cl
ient computers running Windows 2000 and Windows XP
• Client computers running Windows 95, Windows 98, and Windows NT
• Printing from UNIX-based, NetWare, and Macintosh clients
Managing a large number of printers or printing a large number of documents requires more memory,
disk space, and potentially a more powerful processor on the print server. While choosing the server
hardware, ensure that the server has additional disk space for print spooling.
The print service feature on Windows Storage Server 2003 supports network printers only and it is not
intended for use with directly attached printers. The print service on Windows Server 2003 Standard
