Benchmarking Software NAS solutions (Windows Server, OMV, FreeNAS, Synology)

Image
I have an older Synology NAS at home, and I am planning to replace it with a custom built NAS. To decide which system to put on it, I have setup 5 different NAS solution in a virtual environment and measured how fast they are. There were two prerequisites to the candidates: they should support WSD and SMB Multichannel.

Windows 7 immediatly waking up after sleep

At home I have set up a new Windows 7 computer and the intention is to put it to sleep mode when we don't use it, to achieve ~5 sec start time. When I set it up, I realized, that as soon as I put it to sleep mode, it waked up. After checking the event viewer, it turned out that it received the wake up signal from the network. Finaly I figured out that on the configuration menu of the Ethernet adapter on the Power Management tab, I had to check that only allow magic packet to wake up computer. This solved the problem immediately.

Accessing WAP sites from a desktop computer

Sometimes you may need to access WAP sites from your desktop computer, for example if you want to save a downloaded java game or you want to access some information on WAP which is normally only accessible from a phone. There are two problems to be solved: user agent setting for the browser - you may need to change this, in order to make the web site think that you are browsing it from a mobile phone using the operator's wap network, because some content is only available if you are accessing it from the operators network. Changing user agent For the first, theeasiest solution is to use Firefox and then change the 'general.useragent.override' setting of the browser for example to: Nokia6230/2.0+(04.43)+Profile/MIDP-2.0+Configuration/CLDC-1.1+UP.Link/6.3.0.0.0 to simulate a Nokia 6230. You can check your browsers user agent on this web page . For a list of user agent string for different phones go here . Using the WAP network The easiest way of connecting your...

NFS Client for Windows XP computer crashing with large files

I have recently installed a gigabit card to my home fileserver and was very dissapointed, that the speed of network writes and reads did not increased as I expected. I found some Samba improvement tips, but they increased the speed only by ~10 percent, while I would expect to have network speed on the range of 50 Mbytes/sec. To make an experiment I wanted to use NFS instead of Samba, from one unix test it looked much faster than Samba. There is an official Microsoft client for this, it is named Unix Services for Windows, the actual version is 3.5 and it is quite outdated. Still after installing it and configuring both the server and the Windows XP it worked adn when attempting to read files it was quite stable. But as soon as I tried to copy a 4,3 Gbyte ISO image, my XP crashed completly :-( After a lot of search finally I could identify that you should apply the hotfix: KB904838 and this will solve your problem. Back to the original problem, I have measured the following sp...
