The ReadyNAS systems support both RAID
levels. RAID 5 is an industry-standard RAID level whereas X-RAID is
an Infrant patented RAID technology that simplifies and automates
the RAID management process. X-RAID utilizes a one-volume technology
with built-in volume expansion support, either by adding more disks
or by replacing existing disk with larger capacity disks. For
instance, you can start out with one disk, and add up to 3 more
disks when you need more capacity or when you can afford them.
Volume management is automatic. Add a 2nd disk, it becomes a mirror
to the first, providing protection from a disk failure; add a 3rd,
the capacity doubles; add a 4th, and your capacity triples – the
expansion occurring while maintaining redundancy.
X-RAID also provides further expansion capability. At a future point
in time, each disk can be replaced one by one, have it finish
rebuilding, and after the last disk is replaced, your volume
automatically expands utilizing the new capacity. This future-proof
technology allows you to continuously expand as higher-capacity
disks become available.
Performance-wise, X-RAID is optimized for larger sequential access
request pattern, such as video streaming and editing. Performance
over RAID 5 in large data transfer can be as much as 15-20% better.

Where X-RAID excels at large
sequential transfers, RAID 5 performs better in smaller random
access request pattern, fitting better in most office environments.
Full volume management is available when you select RAID 5 (or
Flex-RAID) mode. You can delete the existing volume and recreate one
or more volumes, with each volume with different snapshot space and
quota specification. You also have the flexibility of assigning an
unused disk as a hot spare, allowing for the standby drive to kick
in to replace a failed disk, minimizing the time where you may be
vulnerable to a second disk failure.
In the future when you need more capacity, you can replace each disk
one by one, and when the last disk is replaced, you can create
another volume utilizing the new available space. This is in
contrast to X-RAID where the single volume expands over the new
space.

|
Volume capacity will be limited by the
smallest disk. For example, if you are installing one 250GB drive
and three 750GB drives, your data volume capacity will be limited to
250GB on each of the four disks. In Flex-RAID mode, you can utilize
the leftover space on the 3 750GB disks by creating another data
volume (3 x 500GB). With X-RAID, if you replace the single 250GB
disk with a 750GB disk, your capacity will automatically expand,
utilizing all 750 GB from each of the 4 disks.

NETGEAR will provide data recovery
analysis and service for a fee. Each case will be vary in price
based on time spent. NETGEAR Support can provide an estimate after
doing an analysis.
|
|
|
|
ReadyNAS does not support JBOD,
however, you can create a RAID 0 striped volume across all four
disks or create a separate RAID 0 volume on each disk.
|
|
|
|
The ReadyNAS supports the optional
disk sleep mode. In this mode, disks will go on standby after a
specified time of inactivity.

ReadyNAS NV+, 1100, Rev. B NV and Rev.
B X6/600 support scheduled power on and off. Rev. A NV needs add-on
to turn on this feature, see add-on notes for details.
|
|
|
|
There is a limit of 32,000 users and
32,000 groups, however, depending on application, the ReadyNAS will
support from 1 to 20 concurrent users. For large video files, the
ReadyNAS can stream 4 HD-quality video without frame drops. For
Microsoft Office-type applications, the ReadyNAS will handle many
more concurrent users.
|
|
|
|
Filename length is limited to 255
bytes. If filename contains only alphabet and numbers, this
limitation is the same as most of client. However if filename
contains Germanic umlaut, Chinese character, Kanji, etc., filename
will be limited to less charactors. The maximum filename length will
be 85 characters if filename cosists of only Chinese charactors.
|
|
|
|
The ReadyNAS will support up to 1TB
(terabyte) file size. Some protocols, such as HTTP will have a
limitation where maximum file transfer size can be much less.
|
|
|
|
The ReadyNAS uses Linux Ext2/Ext3 file
system. A typical Linux distro can mount and access the data from
the disks.
|
|
|
|
0-40C. ReadyNAS will gracefully shut
down if hard disk temperature exceeds safe level.
|
|
|
|
No, however you can attach a tape
drive to a PC and backup files from the ReadyNAS.
|
|
|
|
You can use the built-in FrontView
Backup Manager to backup shares to a USB disk, another PC, or
another ReadyNAS. Alternatively, you can use a PC, Mac, or Linux
backup software to backup shares from the ReadyNAS.

First of all, the NV+ is an
evolutionary running production change over the original NV. In
retrospect, the NV itself was already improving through running
production changes, and a lot of features we are introducing
formally in the NV+ hardware had already started appearing in the
latest batches of the NV, starting in August/September timeframe. So
pretty much other than the LCD panel, the hardware on the NV+ is
very much the same as the "rev B" NVs that we have been shipping.
That said, I will post the improvement in the NV+ since the original
NV which was introduced back in February this year. Keep in mind
that the RAIDiator firmware runs across commonly across the ReadyNAS
family, so the software features remain the same.
- LCD panel. Feedback on
status and event information are now available immediately just
by glancing at the NV+. By default, the IP address and disk
usage of the NV+ is displayed, so there's no guessing what IP
the ReadyNAS is set for and how much disk space is still
available. Also status and events such as disk failure, disk
removal and insertion events, USB device events, overtemp
condition, etc are displayed as soon as it's triggered. This is
in addition to the alerts and logging you've grown to be
accustomed to with the ReadyNAS. In addition, boot statuses are
now in readable form, so you no longer need to rely on a LED
chart to see what's going on. The LCD panel will shut itself off
after 5 minutes if there are no failure condition. This prolongs
the life of the LCD and eliminates the unnecessary glow if the
NV+ powered on at night. Also, it keeps the nice clean look
you're accustomed to with the NV.
- Quiet power supply. The
original NV had a small high-revving fan in the power supply
that helped out in cooling the PSU components, but, let's just
say, also caused the NV to be louder than it could be. The NV+
now uses a fanless power supply with updated components that can
withstand the higher temps. This results in the NV+ being
noticeably quieter than the original NV. The "rev B" NV also
utilizes the same NV+ power supply. We value our original NV
users, and will be providing a retrokit power supply kit that
will allow for the same quiet operation.
- Improved fan circuitry.
The mainboard now has a more robust threshold for handling the
wider a ranges or fan RPM. The original NV fan safe range was
~1900-2100 RPM. The NV+ now utilizes a fan that can span speeds
from 1600-3000 RPM, allowing for a slightly quieter setting at
idle mode, and allowing the fan to spin up high enough for the
hottest drives in warmer climates and air condition-less rooms.
The "rev B" NV also utilizes the same mainboard with a different
fan that ranges from 1600-2400 RPM.
- More robust scheduled
power-on. The NV+ mainboard now handles scheduled power-on
events more gracefully when there is no power to the unit.
Previously with the original NV, a power-on event when no AC was
applied would result in needing to release the battery before
the NV would boot again. The "rev B" NV utilizes the same board
so it will also handle this condition identically to the NV+.
- Retrospect for Windows and
Macs. The NV+ comes bundled with a 5-user license for
Retrospect for Windows and Mac users. We have a growing Mac user
base (which we love), and partnering with EMC to bring a quality
backup program for both Windows and Macs was definitely a high
priority. Now more users have a choice on how to safeguard their
data -- centralizing backups with our integrated FrontView
Backup Manager or using Retrospect where FrontView Backup is not
feasible.

Yes in almost all cases; however, it
does degrade performance. The only case which does not support SMB
signing at all is using the ReadyNAS built-in backup manager, with
the Windows (Timestamp) protocol.
