Chapter 1
Getting Acquainted
This chapter provides an overview of the features and capabilities of the ReadyNAS 2100. It also
covers the unit’s physical features, main software, and initial setup steps.
Topics discussed in this chapter include:
• “What is the ReadyNAS 2100?”
• “The Benefits of X-RAID2”
• “Introducing the Status Displays, Ports, and Drive Bay”
• “Initial Setup”
• “The RAIDar Setup Utility”
• “The FrontView Management Console”
What is the ReadyNAS 2100?
NETGEAR ReadyNAS gigabit network storage products provide small and medium sized
businesses with easy-to-use, high-performance network attached storage solutions to share and
protect critical data. Housed in a compact rack mount form factor, the ReadyNAS 2100 supports
up to four SATA I or SATA II hard drives via lockable, hot-swappable disk trays. Three USB 2.0
ports enable the connection of USB drives. Based on current drive capacities, the ReadyNAS
provides up to 8TB of network attached storage that can easily be expanded as larger capacity
drives become available.
ReadyNAS enables users across the LAN, WAN, or over the Internet to back up and share data
from Windows, Macintosh, and Linux systems. ReadyNAS offers extensible robust highavailability data protection. Its fail-safe features include dual redundant Gigabit Ethernet ports,
support for RAID 0, 1, 5, plus hot spare, and NETGEAR’s proprietary X-RAID2
volume expansion. You can also allocate iSCSI target volumes on a ReadyNAS 2100.
ReadyNAS includes a built-in FrontV i ew Web based graphical user interface and setup wizard for
ease-of-use and setup. ReadyNAS continually monitors the entire system for abnormal situations
or part failures. Status indicators in the hardware and software provide quick system status
readings. It e-mails the network administrator alerts about critical changes in the system. Also,
developers can use the Frontview Add-on SDK to uniquely extend ReadyNAS capabilities.

The NETGEAR ReadyNAS Community web site is http://readynas.com, where you will find
reviews of new features, tutorials, software updates, documentation, an active user forum and
much more. For a full list of what is new compared with existing ReadyNAS systems, see
ReadyNAS Specifications on ReadyNAS.com.
The Benefits of X-RAID2
X-RAID2 is a proven patent-pending technology that is available only on ReadyNAS. The
ReadyNAS 2100 supports both X-RAID2, the second generation version of X-RAID, and
RAID 0/1/5.
A major advantage of X-RAID2 is its ability to automatically expand to include the full space of
new disks. When as little as two of your disks have extra capacity, the data volume will
automatically expand its capacity . The capacity of the data volume increases every time you add a
larger disk, regardless of the capacity of the other disks in the system. X-RAID2 lets you do this
without reformatting your disks and shuffling your data back and forth. The process occurs in the
background, so access to the ReadyNAS 2100 is not interrupted. Furthermore, X-RAID2 supports
multiple parity which provides protection against two simultaneous disk failures. For more on XRAID2 and RAID, see Appendix C, “X-RAID2 and RAID”.

Managing Your ReadyNAS 2100
Setting up and managing the ReadyNAS 2100 Network Attached Storage System in your network
is described in this chapter. This chapter contains the following sections:
• “Customizing Network Settings”
• “Updating the Admin Password”
• “Selecting Services for Share Access”
• “Understanding Volume Management”
• “Adjusting System Settings”
• “Configuration Backup”
Customizing Network Settings
Access network settings by via the Advanced Control button, and selecting >Network from the
main menu. From the Network menu, you can then navigate to your basic network settings screens
such as Interfaces, Gateway, DNS, WINS, DHCP, and Route options.
Figure 2-1
Managing Your ReadyNAS 2100 2-1
v1.1, June 2009
ReadyNAS 2100 User Manual
Ethernet Interfaces
Select Network > Interfaces > Ethernet 1 /Ethernet 2 tab pages to specify network interfacespecific settings for Standard Settings, Teaming/Failover, VLAN, and Performance Settings.
Standard Setting
In this section, you can specify the IP address, network mask, speed/d uplex mode, and MTU
settings. In most networks where a DHCP server is enabled, you can simply specify the Use values
from a DHCP server option to automatically set the IP address and network mask.
Figure 2-2
• IP Assignment. Select either Use values from a DHCP server or Use values below.
– If you elect to assign the IP address using Use values from a DHCP server, NETGEAR
advises that you set the lease time on the DHCP server/router to a value of at least a day.
Otherwise, you might notice that the IP address of the unit changes even when it has been
powered down for only a few minutes. Most DHCP servers allow you to assign a static IP
address for specified MAC addresses. If you have this option, this would be a good way to
ensure your ReadyNAS 2100 maintains the same IP address even in DHCP mode.
Tip: Consider reserving an IP address for the MAC address of this Ethernet
interface in your DHCP server (or router). This will give you the stability of
a fixed IP address without the effort of maintaining static addresses.
– If you assign a static IP address by selecting Use values below, be aware that the browser
will lose connection to the ReadyNAS 2100 device after the IP address has been changed.
To reconnect after assigning a static IP address, open RAIDar and click Rescan to locate
the device, and then reconnect.

ReadyNAS 2100 User Manual
• Speed/Duplex Mode (Only applies to 10/100 connections). If you have a managed switch
that works best if the devices are forced to a particular speed or duplex mode, you can select
the setting you want. NETGEAR advises that you keep the setting in an Auto-negotiation
mode otherwise.
Figure 2-3
• MTU. In some network environments, changing the default MTU value can fix throughput
problems. NETGEAR advises that you leave the default setting otherwise.
Figure 2-4
Teaming/Failover
In this section, you can select the desired bonding mode. Network teaming provides a way to
aggregate the two network interfaces into a single logical teamed, or bonded, interface. The
teamed interface can provide for enhanced aggregate performance over a logical single interface
while allowing for fail-over support that reduces the number of single points of failure in the
network.
If you plan to use the Teaming/Failover option, connect both interfaces, configure the
T eaming/Failover options on th e Ethernet 1 tab page, then co nfigure the other options for Ethernet
1 and Ethernet 2 accordingly.
Note: If you plan to reserve an IP address in your DHCP server for the ReadyNAS and
will use the Teaming/Failover option, complete the ReadyNAS bonding of the
Ethernet interfaces before updating the DHCP server address reservation table.
Managing Your ReadyNAS 2100 2-3
v1.1, June 2009
ReadyNAS 2100 User Manual
The following teaming/fail over options are available.
Figure 2-5
Note: To get the full performance benefit of an option, provision servers with dual
Ethernet interfaces, and verify that the LAN switch supports the feature that a
ReadyNAS teaming option may require. A mismatch between the LAN switch and
a ReadyNAS teaming option could degrade the throughput of the ReadyNAS.
• Round-Robin: Transmit packets in sequential order from the first available interface to the
next. This mode provides load balancing and fault tolerance.
• Active Backup: Only one interface in the bond is active. A different interface becomes active
if, and only if, the active interface fails. The MAC address of the bonded interface is externally
visible on only one port to avoid confusing the switch.
• XOR: Transmit based on the default simple transmit hash policy (one, or the other but not
both). This mode provides load balancing and fault tolerance.
• Broadcast: Transmit everything on all slave interfaces. This mode provides fault tolerance.
• IEEE 802.3ad LACP: Creates aggregation groups that share the same speed and duplex
settings. Utilizes all interfaces in the active aggregator according to the 802.3ad specification.
Note: To use this option, the switch to which the ReadyNAS connects must support
IEEE 802.3ad LACP dynamic link aggregation. If the switch supports this
feature, this is the recommended option.
• T ransmit Load Balancing: Channel bonding that does not require any special switch support.
The outgoing traffic is distributed according to the current load (computed relative to the
speed) on each interface. Incoming traffic is received by the current interface. If the receiving
interface fails, another interface takes over the MAC address of the failed receiving interface.
2-4 Managing Your ReadyNAS 2100
v1.1, June 2009
ReadyNAS 2100 User Manual
• Adaptive Load Balancing: Includes Transmit Load Balancing plus Receive Load Balancing
for IPV4 traffic, and does not require any special switch support. The receive load balancing is
achieved by ARP negotiation.
VLAN Settings (Virtual Local Area Network)
In this section, you can specify whether to allow devices residing on different segments of a LAN
to appear in the same segment or, conversely, to allow devices on the same switch to behave as
through they belong to a different LAN.
Figure 2-6
If you wish to use the ReadyNAS 2100 in a VLAN environment, select the Enable VLAN
support check box, and enter a numeric VLAN ID. You need to reboot the ReadyNAS 2100 for
the VLAN function to take effect.
Warning: Do not enable VLAN support unless you are sure that your clients also
support VLAN. Otherwise, you can lose network access to the unit, and you
might need to reinstall the firmware to disable the VLAN setting.
Performance Settings
In this section, you can the Enable jumbo frames option allows you to optimize the ReadyNAS
2100 for large data transfers such as multiple streams of video playback.
Figure 2-7
Managing Your ReadyNAS 2100 2-5
v1.1, June 2009
ReadyNAS 2100 User Manual
Note: Use this option only if your NIC and your gigabit switch support jumbo frames.
The ReadyNAS 2100 supports a 9000 byte frame size. For optimal performance, a
switch capable of this frame size or larger should be used.
Global Network Settings
Figure 2-8
Hostname
The Hostname you specify is used to advertise the ReadyNAS 2100 on your network. You can use
the hostname to address the ReadyNAS 2100 in place of the IP address when accessing the
ReadyNAS 2100 from Windows, or over OS X using SMB. This is also the name that appears in
the RAIDar scan list.
The default hostname is nas- followed by the last three bytes of your primary MAC address.
Default Gateway
The Default Gateway specifies the IP address of the system where your network traffic is routed if
the destination is outside your subnet. In most homes and smaller offices, this is the IP address of
the router connected to the cable modem or your DSL servic e.
If you selected the DHCP option in the Ethernet or Wireless tab, the Default Gateway field is
automatically populated with the setting from your DHCP server . If yo u select ed the S tatic opt ion,
you can manually specify the IP addresses of the default gateway server here.

DNS Settings
The DNS area allows you to specify up to three Domain Name Service servers for hostname
resolution. The DNS service translates host names into IP addresses.
If you selected the DHCP option in the Ethernet or Wireless tab, the Domain Name Server fields
are automatically populated with the DNS settings from your DHCP server. If you selected the
Static option, you can manually specify the IP addresses of the DNS servers and the domain name
here.
WINS
A WINS (Windows Internet Naming Service) server allows the ReadyNAS 2100 or other devices
on the network to be browsed from other subnets. This can be useful if you wish to br owse by
hostname across multiple subnets (for example, over VPN).
Figure 2-9
You can specify the WINS server IP address, or you make the ReadyNAS your WINS server.
DHCP
DHCP (Dynamic Host Configuration Protocol) service simplifies management of a network by
dynamically assigning IP addresses to new clients on the network. The DHCP tab allows you to
specify this device as a DHCP server.

Select the Enable DHCP service check box if you want the ReadyNAS 2100 device to act as a
DHCP server. This is convenient in networks where DHCP service is not already available.
Note: These options are available only if this device is not already using a DHCP address.
Enabling DHCP service on a network already utilizing another DHCP server will
result in conflicts that can disable network access. If you wish to use this device as
a DHCP server, make sure to specify static addresses in the Ethernet and DNS tabs.
Route: A Manual Routing Table
The Route tab allows you to specify a manual routing table for each Ethernet interface. You can
use this option to optimize performance. For example, you could configure a manual routing table
to assure that these Ethernet interfaces were directly routed over a fiber backbone to assure that the
unit would not experience the traffic congestion that can build up on a gigabit segment.

Updating the Admin Password
The Security tab allows you to set the administrator password, administer security, and set up the
password recovery feature on the ReadyNAS.
Note: The RAIDar utility includes a discovery mechanism that enables it to find any
ReadyNAS on the network without needing to know its IP address. Also, RAIDar
does not require a user name and password to monitor a ReadyNAS.
The Admin Password tab allows you to change the administrator user password. The administrator
user is the only user that can access FrontView, and this user has administrative privileges when
accessing shares. Be sure to set a password different from the default password, and make sure that

this password is kept in a safe place. Anyone who obtains this password can change or erase the
data on the ReadyNAS.

Note: In User or Domain security mode, you can use the admin account to log in to a
Windows share, and perform maintenance on any file or folder in that share. The
admin user also has permission to access all shares to perform backups.
As a safeguard, you are requeste d to enter a pas sword recovery question, the expected answer, and
an e-mail address. If, in the future, you forget the password, you can go to
https://<ReadyNAS ip_address>/password_recovery. Successfully answering the questions there
resets the Admin Password, which is sent to the e-mail address you enter on this screen.

Selecting Services for Share Access
The Services screen allows you to manage various services for share access. This in effect controls
the type of clients you wish to allow access to the ReadyNAS 2100.
Figure 2-13
Three types of services are available: Standard File Protocols, Discovery Services, and Installed
Add-ins such as streaming services. These different services are explained in the following
sections.
Standard File Protocols
The standard file protocols are common file-sharing services that allow your workstation clients to
transfer files to and from the ReadyNAS 2100 using built-in file manager-over-network file
protocols supported by the client operating system.
The available services are:
• CIFS (Common Internet File Service). Sometimes referred to as SMB. This protocol is used
mainly by Microsoft Windows clients, and sometimes by Mac OS X clients. Under Windows,
when you click on My Network Places Network Neighborhood, you are going across CIFS.
This service is enabled by default and cannot be disabled.
• NFS (Network File Service). NFS is used by Linux and Unix clients. Mac OS 9/X users can
access NFS shares as well through console shell access. The ReadyNAS 2100 supports NFS
v3 over UDP and TCP.

• AFP (Apple File Protocol). Mac OS 9 and OS X works best using this protocol as it handles
an extensive character set. However, in mixed PC and Mac environments, it is advisable to use
CIFS/SMB, unless enhanced character set support is necessary on the Mac.The ReadyNAS
2100 supports AFP 3.1.
• FTP (File Transfer Protocol). Widely used in public file upload and download sites.
ReadyNAS 2100 supports anonymous or user access for FTP clients, regardless of the security
mode selected. If you wish, you can elect to set up port forwarding to nonstandard ports for
better security when accessing files over the Internet.
• HTTP (Hypertext Transfer Protocol). Used by Web browsers. ReadyNAS 2100 supports
HTTP file manager, allowing Web browsers to read and write to shares using the W eb browser.
This service can be disabled in lieu of HTTPS to allow for a more secure transmission of
passwords and data. With the option to redirect default Web access to a specified share , you
can transparently force access to http://readynas_ip to http://readynas_ip/share. This is
useful if you do not want to expose your default share listing page to outsiders. All you need in
the target share is an index file such as index.htm or index.html. You have the option of
enabling or disabling login authentication to this share.
• HTTPS (HTTP with SSL encryption). This service is enabled by default and cannot be
disabled. Access to FrontView is strictly through HTTPS for this reason. If you want remote
Web access to FrontView or your HTTPS shares, you can specify a nonstandard port (default
is 443) that you can forward on your router for better security . You can also regenerate the SSL
key based on the hostname or IP address that users will use to address the ReadyNAS 2100.
This allows you to bypass the default dummy certificate warnings whenever users access the
ReadyNAS 2100 over HTTPS.
• Rsync. An extremely popular and efficient form of incremental backup made popular in the
Linux platform but now available for various other Unix systems as well as Windows and
Mac. Enabling rsync service on the ReadyNAS 2100 allows clients to use rsync to initiate
backups to and from the ReadyNAS 2100.

services. OS X has built-in Bonjour support, and you can download Bonjour for Windows
from Apple’s website.
• UPnP provides a means for UPnP-enabled clients to discover the ReadyNAS 2100 on your
LAN.
