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 Pro introduces X-RAID2, the 2nd 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 to 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 X- RAID 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.

1-2	Getting Acquainted

v1.3, November 2008

ReadyNAS Pro Business Edition User Guide

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 advantave 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. 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 Pro Business Edition is not interrupted.

Others may claim that they have “online” RAID expansion just like X-RAID2, but take a closer look and you’ll see it’s just not that simple. Unlike X-RAID2, 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.

Setting Up and Managing Your ReadyNAS Pro

Setting up and managing the ReadyNAS Pro Network Attached Storage System Business Edition 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”

•“Setting Up Printers”

•“Adjusting System Settings”

•“Configuration Backup”

Customizing Network Settings

Access network settings by clicking 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

Ethernet Interfaces

Select Network > Interfaces > Ethernet 1 /Ethernet 2 tab pages to specify network interfacespecific settings for Standard Settings, Teaming/Failover, VLAN Settings 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.

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 Pro Business Edition 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 Pro Business Edition 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.

•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. First, set the Teaming/Failover on the Ethernet 1 tab page, then configure the other options for Ethernet 1 and Ethernet 2 accordingly.

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.

Figure 2-5

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.

Setting Up and Managing Your ReadyNAS Pro

v1.3, November 2008

ReadyNAS Pro Business Edition User Guide

•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.

•Transmit 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.

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 Pro Business Edition in a VLAN environment, select the Enable VLAN support check box, and enter a numeric VLAN ID. You need to reboot the ReadyNAS Pro Business Edition 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 Pro Business Edition for large data transfers such as multiple streams of video playback.

Figure 2-7

Note: Use this option only if your NIC and your gigabit switch support jumbo frames. The ReadyNAS Pro Business Edition 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 Pro Business Edition on your network. You can use the hostname to address the ReadyNAS Pro Business Edition in place of the IP address when accessing the ReadyNAS Pro Business Edition 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 service.

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 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 Pro Business Edition or other devices on the network to be browsed from other subnets.

Figure 2-9

If you do not have an existing WINS server, you can designate the ReadyNAS Pro Business Edition to be one. Simply select the Become a WINS server check box, and configure your Windows PC to specify the ReadyNAS Pro Business Edition 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.

Figure 2-10

Select the Enable DHCP service check box if you want the ReadyNAS Pro Business Edition 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. 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.

Figure 2-12

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 requested to enter 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.
