CPU Specs of the ReadyNAS

By dbott | December 3, 2010

Don’t take this as gospel, but I believe the CPU specs are as follows:

Sparc Line

Duo – sparc-based IT3107
NV+ – sparc-based IT3107

Ultra Line

Ultra2 – 1.8 GHz Atom D425 (single core) [Update: Starting May 2011 Ultra2 will ship with 1.5 GHz CPU; performance difference is minimal, if any; price decreased by $100.]
Ultra2 Plus – 1.8 GHz Atom D525 (dual core)
Ultra4 – 1.66 GHz Atom D410 (single core)
Ultra4 Plus – 1.66 GHz Atom D510 (dual core)
Ultra6 – 1.66 GHz Atom D510 (dual core)
Ultra6 Plus – E2160 1.8Ghz CPU (dual core)

Pro Line

First Generation (which will likely be discontinued once current supply has been sold off):
NVX Pioneer Edition – Intel Tolapai SiC @ 1.06 GHz
NVX Business Edition – Intel Tolapai SiC @ 1.06 GHz
Pro Pioneer Edition – E2160 1.8Ghz CPU (dual core)
Pro Business Edition – E2160 1.8Ghz CPU (dual core)

Second Generation:
Pro2 – 1.8 GHz Atom D525 (dual core)
Pro4 – 1.66 GHz Atom D510 (dual core)
Pro6 – E5300 2.6Ghz CPU (dual core)

When the Pro was first announced a few years back, a number of users requested a diskless version of the Pro. Netgear released the “Pioneer Edition” of the Pro (and subsequently, the NVX) with a reduced feature-set (no Active Directory support, no SNMP, no snapshots, etc.) in a diskless chassis to satisfy these users. The problem was that it created some confusion, as some folks bought it thinking that it had the same features as the pre-populated units (aka “Business Edition”).

I’m guessing that Netgear has decided to re-brand the products to avoid confusion. Business users requiring things like AD support, snapshots, rsync-over-ssh, enterprise-class disks, 5-yr warranty, etc. should buy the Pro. Home users not requiring those features should buy the Ultra.

Using the ReadyNAS to create a Network UPS for PCs

By dbott | October 8, 2010

The ReadyNAS can issue “UPS commands” to other devices, effectively allowing your UPS to be networked and shutdown client PCs. I’ve got my UPS connected to the NAS and setup using the procedure below.

Basically, you need to install WinNUT on your PC.  Instructions for OSX and Linux can be found below.

You also need to configure your ReadyNAS to communicate with the PC:

  1. Connect the UPS to the NAS via USB.
  2. Login to Frontview on your NAS.
  3. Click SYSTEM –> POWER.
  4. Scroll down to the UPS section.
  5. Check the box that says “Enable network sharing of attached UPS
  6. Enter the IP address of the PC or the subnet (i.e.

7. Edit the WinNUT configuration file (typically C:\Program Files\WinNUT\upsmon.conf). In my case, my ReadyNAS uses a static IP ( and my computers use DHCP on the subnet). I’ve edited out most author comments, just leaving the values I used:

#  --------------------------------------------------------------------------
#  MONITOR <system> <powervalue> <username>  <password> ("master"|"slave")

MONITOR UPS@ 1  monuser pass slave

#  --------------------------------------------------------------------------


#  --------------------------------------------------------------------------
#  NOTIFYCMD <command>

NOTIFYCMD "c:\\Program  Files\\WinNUT\\alertPopup.exe"

#  --------------------------------------------------------------------------
#  POLLFREQ <n> 


#  --------------------------------------------------------------------------


#  --------------------------------------------------------------------------
#  HOSTSYNC - How long upsmon will wait before giving up on another upsmon


#  --------------------------------------------------------------------------
#  DEADTIME - Interval to wait before declaring a stale ups "dead"


#  --------------------------------------------------------------------------
#  NOTIFYMSG - change messages sent by upsmon when certain events occur

NOTIFYMSG  ONLINE "UPS %s is getting line power"
NOTIFYMSG ONBATT "Someone  pulled the plug on %s"
NOTIFYMSG LOWBATT "UPS has a low battery"
NOTIFYMSG  SHUTDOWN "The system is being shutdown"

#  --------------------------------------------------------------------------
#  NOTIFYFLAG - change behavior of upsmon when NOTIFY events occur


#  --------------------------------------------------------------------------
#  RBWARNTIME - replace battery warning time in seconds


#  --------------------------------------------------------------------------
#  NOCOMMWARNTIME - no communications warning time in seconds


#  --------------------------------------------------------------------------
#  FINALDELAY - last sleep interval before shutting down the system


Here’s a couple of screenshots from my PC when the UPS gets disconnected:

Mac Users

Update 2: See Infinite’s post here for OSX users:

Update 1: See Egg’s post here for OSX users:

It looks like there’s an OSX port of NUT:

I took a quick read of the HOWTO above.  The HOWTO explains how to setup a MASTER on OSX (which is the device that the UPS is directly connected to), as well as CLIENT machines to monitor the UPS.

For OSX users, the NAS is the MASTER and you’ll just need to configure NUT as a client that points to your NAS.

Then configure the conf file to suit your network.

Linux Users

Most distros should have NUT available through the package management software repositories.  The link below provides links to some related packages:

The original how-to is documented in the ReadyNAS forums here:

Configuring Your ReadyNAS for Flex-RAID

By dbott | October 6, 2010

By default, the ReadyNAS configures itself using X-RAID. X-RAID is Netgear’s eXpandable RAID technology that allows you to expand the size of your hard drive both horizontally (by adding more drives) and vertically (by replacing smaller drives with larger drives). In the event that you wish to configure your ReadyNAS for another RAID level, such as RAID 0, 1, 5* or 6**, you’ll need to perform a factory default and during the 10-minute setup window select Flex-RAID as the RAID type using RAIDar.
* Requires a ReadyNAS with at least 4-bays and at least 3 drives installed.
** Requires a ReadyNAS with at least 6-bays and at least 4 drives installed.


  1. Install RAIDar on your computer
  2. After testing and installing your drives into the ReadyNAS, connect the NAS to the network and power it on.
  3. On your computer, run the RAIDar discovery tool and scan for your ReadyNAS before 10-minutes expires, otherwise the NAS will default to X-RAID mode
  4. Once the NAS has been discovered you can select your desired RAID level:
  5. After selecting Flex-RAID, the system will create a RAID 1 volume automatically. You need to delete the existing volume first:
  6. Once that’s done, you should be able to select which type of RAID array you wish to create, as well as which drives it should be created on:
  7. After creating the volume, you will be prompted to restart the device before the volume is added:

    If you’ve already put data on it & the RAID level is X-RAID, you’ll need to backup your data & start again.
