Agree. The cost of replacing building cables + jacks could be around 100$ per jack, depending on the building, number of jacks etc. There is probably much better value in other investments. My experience as a network technichan is that it's much better to have some monitoring software raise alerts when there are significant numbers of errors specific switchports. Such errors indicate physical cable or switchport problems, duplex problems or a faulty nic. With such alert, you will detect the problems before anyone else notice them. However, I would recommend a more frequent replacement of patch cabling. Broken patch cables cause a lot of trouble.

Comment Re:Swedish does not derive from Latin (Score 1) 88

Sweden has an strong tradition of government transparency and a lot of document is publicly availible. Anyone can request any government document which is not explicitly classfied as secret: http://en.wikipedia.org/wiki/Freedom_of_information_legislation#Sweden

In Sweden, the Freedom of the Press Act of 1766 granted public access to government documents. It thus became an integral part of the Swedish Constitution, and the first ever piece of freedom of information legislation in the modern sense. In Swedish this is known as Offentlighetsprincipen (The Principle of Public Access),[32] and has been valid since.

The Principle of Public Access means that the general public are to be guaranteed an unimpeded view of activities pursued by the government and local authorities; all documents handled by the authorities are public unless legislation explicitly and specifically states otherwise, and even then each request for potentially sensitive information must be handled individually, and a refusal is subject to appeal. Further, the constitution grants the Right to Inform, meaning that even some (most) types of secret information may be passed on to the press or other media without risk of criminal charges. Instead, investigation of the informer's identity is a criminal offense.

However, compared to the US, sweden has a weaker freedom of press.

Sweden prohibits hate speech, hets mot folkgrupp, and defines it as publicly making statements that threaten or express disrespect for an ethnic group or similar group regarding their race, skin colour, national or ethnic origin, faith or sexual orientation.

http://en.wikipedia.org/wiki/Hate_speech#Sweden I would not say that the swedish legal system is better than the american. Sure, we don't have the problem with excessive damages but on the other hand, individuals are powerless agains big corporations and the government.

Comment High Availability & Live Migration for free? (Score 1) 272

I am also considering to build a virtualization environment at home using commodity hardware and free (as in beer) software. I am considering 2 (or more) virtualization machines (1 x quadcore, 16 GB ram, gigabit lan) and 2 mirrored iscsi hosts (1 x quadcore, 8 GB ram, 5 x 1,5 TB SATA, Solaris+ZFS, gigabit lan). However, I cannot find any way to get the High Availability and Live Migration features without paying horrible license costs.

Is there any way to get these features for free?

Comment Re:bill, don't throttle (Score 2, Insightful) 640

Don't bill or throttle, instead prioritize latency-sensitive protocols over other less sensitive traffic.

Prio 1: Voice, http, https, gaming traffic
Prio 2: pop3, smtp, ftp
Prio 3: Other traffic


I've done this myself on a 100 Mbit/s LAN with 500 homes sharing a 20 Mbit/s internet uplink. The uplink was almost continously congested but the web browsing experience was nice and snappy. When the prioritization was implemented, customer complaints dropped sharply.

Comment Re:Define "Standby" (Score 2, Interesting) 222

I also want my workstation/server to be always-on but the power cost is just too high. What I want is a computer that consumes little or none power when in idle or low-performance mode. How much juice it's eating when I'm actively using it is less relevant. Any tips on how to build a such computer?

Comment Re:SMB (Score 1) 517

I agree, SMB has good compatibility and would be a good choice.

Consering the NAS, your requirements can be boiled down to:
High performance (Stability, high throughput, large volume)
Simple deployment (In terms of your own labor)
SOHO pricepoint ( under $5000 )

The problem is that you only get to choose 2.

High performance + simple deployment = Business-grade solution installed by consultant

High performance + SOHO pricepoint = Server with SATA Raid or ZFS

Easy deployment + SOHO pricepoint = SOHO NAS (ReadyNAS, Synology, etc)


Also, remember the backup. And backup is expensive, far more expensive than disk space.
