  • The team did not discontinue the NDAS software for Linux. Sorry for temporary misunderstanding( http://code.ximeta.com/trac-ndas/ticket/749 ). All reports about issues, suggestions and your patches are always welcomed.

2. Getting / Installing NDAS Software for your system

2.1 Installing using package

  • Some packages submitted by users are available. Search the tickets for your distribution, and check the home page.  http://linux.iocellnetworks.com. To build a package Please follow the instruction in 2.2

2.2 Building a rpm / deb package file for your system

  • NDAS Software contains Linux kernel modules and Linux kernel requires modules to be built with same kernel and compiler. And there can be incompatibilities between our build system and your system's library. So in many case you may not find a proper NDAS Software for your system. In this case, you should build the NDAS Software packages from your system.
  • Last official NDAS for Linux tarballs: When all bugs are out, we will post source based on Linux kernel version #.#.#. If possible, NDAS should become an installable module in the Linux mainstream, with NDAS Admin or Kandas provided as the distributable package.

2.3 Building / Installing drivers manually

  • If your system is not yet supported by NDAS Software's package build procedure such as gentoo, you should build and install the driver manually.
  • Please follow the instruction in following links

3. Using NDAS Software

4. Uninstalling NDAS Software

5. Developing the NDAS Software

5. Porting the NDAS Software

Do you have the embedded device that needs a storage?
Port the NDAS Software, you will have the better performance than CIFS/SMB and USB2.0(in gigabit network)

6. Bug report

If you find bugs, please report it by  issuing a ticket. Please include the result of the following commands when you report a bug; 

rpm -qa ndas-kernel
rpm -qa ndas-kernel-smp
rpm -qa ndas-admin
rpm -qa kernel
rpm -qa kernel-smp
ls -l /lib/modules/*/kernel/drivers/block/ndas/*
cat /proc/version
uname -a
cat /etc/redhat-release /etc/fedora-release /etc/SuSE-release
gcc --version

For debian, ubuntu, use the following instead of above; 

dpkg -l ndas-\*
dpkg -l linux-image\*
dpkg -l kernel-image\*
ls -l /lib/modules/*/kernel/drivers/block/ndas/*
cat /proc/version
uname -a
cat /etc/debian_version
gcc --version

7. Join the Team!!

Linux is expanding rapidly into the home and workplace. In 2011, our user survey showed significant increase. The number of miniature computers using Linux or derivatives also grows exponentially. As we move the development of NDAS to the open source versions, it is a good opportunity for developers to explore new avenues, get some freebies and boost resume. We really appreciate those who reported the bugs and submitted patches and we look forward to serving the backup and storage needs of Linux based computers and other devices.

If you would like to checkout the full source code for NDAS, try 

$ git clone gitosis@ndas4linux.iocellnetworks.com:dansdriver

If you can join in trimming the code, and work toward integration to the linux mainline, please send your public key and brief introduction of your experience to linux@…

8. Products similar to NDAS

Standard "NAS" systems are becoming popular, and manufacturers are creating various low cost units that are getting pretty easy to use. Some choose NAS specifically for the wide area network access. These systems often require more time to setup and usually transfer data slower. It is also perfectly possible to take a some kind of a small computer, add enough storage to it, and configure it as a storage server. But this is typically what folks try to avoid by purchasing an NDAS device. For those of you interested in this kind of joy,  FreeNAS or  OpenFiler could do the trick. Now, if you are only interested in the lower cost, block level approach, some products similar to NDAS do exist. Some alternative approaches include:

Both ATA over Ethernet and HyperSCSI are conceptually quite similar to NDAS and bypass all the network layers above Ethernet (IP, TCP, UDP). However, they are more industry level products, meaning the hardware that uses those protocols are still quite large and expensive.
