Question about B3

Post by switchgott »

Hi,

i habe some question about the b3.

Does it hava a RTC (real time clock) ?

How much power consumpton does it have with a 2,5 HDD and WIFI on?

And, will we get debian 7 official on it?

Big thanks for your answer.

Bye

Of course it has a clock. To get accurate time it is common though to sync with internet time servers (ntp)

The specs state ~7 Watts average. Make and model of the drive can cause deviations from these specs though.

And, will we get debian 7 official on it?

At present that does not seem likely.

Big thanks for your answer.

And maybe to clarify, it has a battery powered hardware RTC; that runs also when the device is unplugged.

You can calculate around 1W power for CPU and other small stuff, and 1-2W for wifi, depending on usage. Then the disk usage will add, for a small SSD it's close to nothing, for a 1TB rotating drive it can be 4-5W.

so I'd say 2 - 6W depending on disk and usage.

Big thanks for your replay...
this sounds realy good..

I guess a 2,5 500gb drive will only get 3 Watt on heavy use.

Thats realy good.
Even the dockstar wont get this watt..
And the b3 has got 2 Gigabit interfaces !!So if you use it as a router with dual nic, the power consumption is the same?

Could you please tell me, how the php fastcgi performance is?
Ask because of owncloud on some other php cgi applications.

I guess the excito is the best internet router device with home services :lol:

Any idea, why we wont get debian 7 ?

Debian 6 will be discontinue, so we wont be able to get neweset software pakets.

Could we use arch linux with bubba server?

Thanks again
johannes

Yes, this is included in the calculation.

I can't say, but if you want to, I can give you access to a demo unit, which sits with a good internet connection, and you can do tests? PM me for details.

The product is soon going to be discontinued from Excito, and we have no resources to continue development, sorry. However, there are initiatives from the community to get more recent Debian onto the B3, read more here: http://forum.excito.net/viewtopic.php?f ... +installer.

Everything is possible, but this machine is not standard hardware (hence the low power consumption) so it is a lot of work to port it. As far as I know noone attempted to do so yet.

You wouldn't be using fastcgi for regular web pages, but apache mod_php. Fastcgi is only used on the B3 to service the admin pages, running php as a service with root credentials. Performance is quite good, but you should realize that this is no mainframe and performance will degrade rapidly if the number of visitors increases. As an alternative you could switch to Nginx for serving web pages (just search the forum), which eliminates a lot of overhead but does require using fastcgi

I'd agree to that. The best thing as far as I see it it that you can change just about everything. That would include installing a completely different Linux disto that supports this type of hardware. Obviously this means loosing the Bubba management interface.

As indicated in the topic that Johannes linked to, there is an issue with the boot manager that sits in (flash) hardware and the current kernels used in Debian 7. At present that makes it rather pointless to attempt any development of Wheezy on B3. And yes, Excito also does not have any software developers on board any more, so it will probably need to be a community effort if we do want to move on to Debian 7

Big thanks for this information..

There are a lot of ideas, what we can do with b3.

I dont know, why i didnt see excito b3 bevor..

Not nice to hear that there is a problem with boot manager.
But what about arch linux?
Couldnt you switch the bubba to arch?

Yes you could switch to arch, or gentoo, or any other disto that will support amrvtel. That doesn't change the fact though that you can't boot any kernel from 3.1 upto the current 3.14 version. And that the kernel requires some very specific patches to match the B3 hardware - although I have a feeling that a Sheevaplug kernel might work as well since it uses the same SOC base.
