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?”
• “What Are the Benefits of X-RAID and X-RAID2?”
• “Introducing the Status Displays, Ports, and Drive Bay”
• “Initial Setup”
• “The RAIDar Setup Utility”
• “The FrontView Management Console”
• “NETGEAR ReadyNAS Community”
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 or printers. Based on current drive capacities, the
ReadyNAS provides up to 6TB of network attached storage that can easily be expanded as larger
capacity drives become available.
The ReadyNAS enables users across the LAN, WAN, or over the Internet to back up and share
data from Windows, Macintosh, and Linux syst ems. 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
TM
for automatic
volume expansion. You can also allocate iSCSI target volumes on ReadyNAS 2100, ReadyNAS
NVX, and the ReadyNAS Pro series.
In addition to a Web based graphical user interface (GUI) and setup wizard for ease-of-use and
setup, ReadyNAS features status indicators that provide quick system status readings and
incorporates an active system monitoring capability which continually monitors the entire system

for abnormal situations or part failures and e-mails system alerts to the network administrator. In
addition, the Frontview Add-on SDK provides developers the tools for uniquely extending
ReadyNAS capabilities. For a full list of what is new compared with existing ReadyNAS systems,
see ReadyNAS Specifications on ReadyNAS.com.
What Are the Benefits of X-RAID and X-RAID2?
Shipping in volume since 2004, X-RAID is a proven patent-pending technology that is available
only on ReadyNAS. ReadyNAS 2100 ships with X-RAID2, the 2
nd
generation version of
X-RAID.
X-RAID Is Expandable RAID
RAID stands for Redundant Array of Independent Disks, which is a way of protecting your data in
case of a disk failure. The X in X-RAID stands for “expandable”; X-RAID is expandable RAID.
X-RAID technology simplifies volume management. What most people want t o do with their data
volumes over time is either add redundancy or expand them without the headaches usually
associated with doing so. By using simple rules, X-RAID hides the complexities yet still provides
volume management features previously available only in enterprise-level storage solutions.
X-RAID Simplifies Redundancy
To maintain redundancy from disk failure, X-RAID requires a one-disk overhead. In a two-disk XRAID volume, the usable capacity is one disk, in a three-disk volume the usable capacity is two
disks, in a four-disk volume, the usable capacity is three disks, etc.
No Redundancy with a Single Disk but Easy to Add Disks with X-RAID
Even with RAID, there is no data redundancy with one disk; if that disk fails, your data is lost. If
you have a one-disk ReadyNAS and want protection from disk failure, you have to add a 2nd disk
that is at least as large as the first. It can be ‘hot-added’ while the ReadyNAS is running.
Whenever you add or replace a disk, the ReadyNAS will initialize it, scanning to make sure the
disk is good. Once added, your 2nd disk will synch with the 1st disk. Depending on the disk size,
the synch may take anywhere from 30 minutes to several hours. The sync occurs in the
background so you can still keep on working with the ReadyNAS during this time.
After the sync completes, your data volume is now redundant, meaning if one of the disks fails, the
other disk still contains the data, and thus your data is now fully protected from a disk failure.
ReadyNAS 2100 User Manual
Getting Acquainted 1-3
v1.0, May 2009
The X-RAID Data Volume
X-RAID has one data volume. This volume uses the capacity of the smallest disk from each disk.
For instance, if you had one 80 GB disk and two 250 GB disks, only 80 GB from each disk is used
in the volume. The leftover space on the 250 GB disks is reclaimed only when the 80 GB disk is
replaced with a 250 GB or greater capacity disk. However, as you will see below,
X-RAID2 is more flexible in how it handles volume expansion.
Horizontal Expansion (More Disks) vs. Vertical Expansion (Larger Disks)
The process of expanding the number of disks we call horizontal expansion. X-RAID also
supports vertical expansion by adding larger disks. With first generation X-RAID, horizontal
expansion, the capacity is limited to a multiple of your original disk. As larger or more affordable
disks become available, you take advantage of vertical expansion to grow the size of your volume.
You can add additional disks of at least the size of the 1st disk. You can add a larger disk, but with
the original X-RAID extra space will not be used until all disks are at least that size.
X-RAID supports replacing disks with larger capacity ones while keeping the volume data intact.
Simply replace each of your disks one by one with a larger disk. After the init process, the disk will
be synchronized to restore data redundancy. Again, this process can take 30 minutes to several
hours. Both processes occur in the background, so you can continue using the ReadyNAS as usual.
Once you have done this for all disks in the system, just reboot the ReadyNAS to start the volume
expansion which occurs in the background. When the process completes, your data will remain
intact, but your data volume capacity will have expanded to a multiple of the your smallest
capacity disk. That multiple is the total number of disks minus 1 for redundancy. For example, if
your system now has 3 disks, and the smallest is 500 GB, then the volume capacity is 1TB.
The beauty with vertical expansion is that you can keep expanding your volume repeatedly with
larger capacity disks, a definite future-proof advantage that you can count on with the ReadyNAS.
X-RAID2 Is Even More Flexible
Now, X-RAID2 will automatically expand when as little as two of your disks have extra capacity,
as you can see in this animation. Your data volume can keep growing every time you add a larger
disk after that. 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.
Others claim they have “online” RAID expansion just like X-RAID2, but take a closer look and
you’ll see it’s just not that simple. Not only will there be complex RAID migration steps, but they
cannot recover from a power loss during the process. With X-RAID2, you can turn off the power
as many times as you want during the expansion, and it’ll continue where it left off.

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/duplex 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.
• 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 al low 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.
– 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.
Figure 2-2
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.

• 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.
• MTU. In some network environments, changing the default MTU value can fix throughput
problems. NETGEAR advises that you leave the default setting otherwise.
Teaming/Failover
In this section, you can select the desired bonding mode.
If you plan to use the Teaming/Failover option, connect both interfaces, configure the Teaming/
Failover options on the Ethernet 1 tab page, then configure the other options for Ethernet 1 and
Ethernet 2 accordingly.
Figure 2-3
Figure 2-4
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.

Network teaming provides a way to aggregate the two network interfaces into a single logical
teamed, or bonded, interface. The teamed interface allows for fail-over support and can provide for
enhanced aggregate performance over a single interface.
The following bonding options are available. Note that the option you select may affect the
ReadyNAS network performance.
• 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 bond’s MAC address is externally visible on only
one port to avoid confusing the switch.
• XOR: Transmit based on the default simple transmit hash policy. This mode provides load
balancing and fault tolerance.
• Broadcast: Transmit everything on all slave interfaces. This mode provides fault tolerance.
• IEEE 802.3ad: Creates aggregation groups that share the same speed and duplex settings.
Utilizes all interfaces in the active aggregator according to the 802.3ad specification. You will
need a switch that supports IEEE 802.3ad Dynamic link aggregation.
• 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.
• 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.

Note: To get the full performance benefit of the teaming option, configure the LAN
switch options accordingly, and provision servers with dual Ethernet interfaces.

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.
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.
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 2-6
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.
Figure 2-7
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.

Hostname
The Hostname you specify is used to advertise the ReadyNAS 2100 on your network. Y ou 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 D SL se rvic 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 you selected the Static option,
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
Figure 2-8
ReadyNAS 2100 User Manual
Setting Up and Managing Your ReadyNAS 2100 2-7

Static option, you can manually specify the IP addresses of the DNS servers and the domain name
here.
WINS
The WINS option allows you to specify the IP address of the WINS (Windows Internet Naming
Service) server. A WINS server is typically a Windows server on the network that allows the
ReadyNAS 2100 or other devices on the network to be browsed from other subnets.
If you do not have an existing WINS server, you can designate the ReadyNAS 2100 to be one.
Simply select the Become a WINS server check box, and configure your Windows PC to specify
the ReadyNAS 2100 IP address as the WINS server. This can be useful if you wish to browse by
hostname across multiple subnets (for example, over VPN).
DHCP
The DHCP tab allows you to specify this device as a DHCP (Dynamic Host Configuration
Protocol) server. DHCP service simplifies management of a network by dynamically assigning IP
addresses to new clients on the network.

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.
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.
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
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. If you wish to use this device as a DHCP server, make sure to
specify static addresses in the Ethernet and DNS tabs.

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.

this password is kept in a safe place. Anyone who obtains this password can change or erase the
data on the ReadyNAS.
As a safeguard, you are requ ested to ente r a password 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. Three types of services are
available: Standard File Protocols, Streaming Services, and Discovery Services. These different
services are explained in the following sections.
Standard File Protocols
The standard file protocols are common file-sharin g services that allow your workst ation clients to
transfer files to and from the ReadyNAS 2100 using built-in file manager-over -network file
protocols supported by the client operating syste m.
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.
