What is the ReadyNAS Pro?
NETGEAR ReadyNAS Pro 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 desktop form factor, the ReadyNAS Pro products
support up to six SATA I or SATA II hard drives via six 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 Pro provides up to 9TB of network attached storage that can easily be expanded as
larger capacity drives become available.
The ReadyNAS Pro enables users across the LAN, WAN, or over the Internet to back up and share
data from Windows, Macintosh, and Linux systems. ReadyNAS Pro offers extensible robust high-
availability data protection. Its fail-safe features include dual redundant Gigabit Ethernet ports and
support for RAID 0, 1, 5, RAID 5 plus hot spare, RAID 6, and NETGEAR’s proprietary
X-RAID2TM for automatic volume expansion.
In addition to a Web based graphical user interface (GUI) and setup wizard for ease-of-use and
setup, ReadyNAS Pro features an LCD display that provides quick and intuitive 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 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.

v1.3, November 2008
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.

Choosing a Location for a ReadyNAS Pro
The ReadyNAS Pro is suitable for use in an office environment where it can be free-standing,
located in a wiring closet or equipment room.
When deciding where to locate the unite, ensure that:
• It is accessible and cables can be connected easily.
• If it will be protected by an uninterruptable power supply (UPS), its power cable can be
securely and safely connected to the UPS.
• Water or moisture cannot enter the case of the unit.
• Airflow around the unit and through the vents in the side of the case is not restricted.
• The air is as free of dust as possible.
• Temperature operating limits are not likely to be exceeded. For information on the
recommended operating temperatures, refer to the data sheet on the NETGEAR website.
Initial Setup
Follow the instructions in the NETGEAR Installation Guide that came with your unit to install
your NETGEAR® ReadyNAS™ Pro. An electronic copy of the installation guide is on the
