Have anyone used an powervault 120 DLT with linuxmce? With which software do you use to manage the autoloader?

So pics on the system. I slowly getting ready to start installing the system...

Just curious how people have solved there backups on there systems.

Do people just use an rsync script?

micklen I don't know if this is to late but I'm using an athlon 5000 at 2.6ghz and i'm not overly happy with performance.  Currently I'm only doing media on 4 mds and it's not as great as I'd like.  You'll have one whole core and .3 ghz more than me but i was thinking of something in the quad core department for my next core build.  Well... as long as I'm not forced to build out a new core before my wife and I start shopping for our next house (1-2 years) i will be shooting for a dual quad core setup in the 3.0ghz department.  I plan on doing the x10 through out, cameras, alarm, and a md in every room so I want something beefy.  My core now is okay for a general end user, someone with a small amount of mds not looking to get to fancy.   I don't know if this is normal but adding a md is like a major system change that usually requires me to restart the core and A quick reload isn't always quick.  Boot time for the mds and core is also pretty long, about 5 mins for the core.  You sound like a geek like me, you may want something beefier like me. 

Also if I were you i wouldn't put my core and nas on the same server, lmce, windows, or whatever that is never a good idea.  The core is a server and you usually don't want your server doing a hundred different things when it doesn't have to.  When I first setup my core I had a weak moment and the thought crossed my mind.  That was before i did my first file transfer while watching a movie.  The video was playing from the hd in the core then i started copying a different movie to the core to watch next.  The one i was watching started skipping the second i started the transfer and this was at lan speeds on a full gig network.  I've used freenas and it's not my number one choice but it's better than dumping files directly on the core.  You have a full rack, get a 4 or 5 U case and start your nas with that.  Eventually you'll run out of space but with a dedicated 4U nas you can add more drives and raid controllers as needed.  This would apply to your backups also, I would look for a solution that would backup lmce remotely.  I like to think bigger.  Why backup just lmce when you can backup everything on your network, do you really want your core backing up every computer on your network? I don't think so .

Don’t virtualize anything!! I’m all for virtualization, I have a dedicated vmware server on my network but I wouldn’t use it here.  Your Nas is going to use a decent amount of cpu time, it will create a lot of IO and network traffic.  I have not gotten around to checking yet but I’d be shocked if the core didn’t use a decent amount of ram and I’m sure it’s generating a fair share of IO and network traffic.  Your 3 cores won’t be enough to power the core, nas and what ever else you have on there… well not to my standards anyway, if you’re cool with it run with it.  I hate waiting on computers; I feel that we’re too far along for that.  Now I don’t know you, if you have the resources to drop $5k-$10K on a server that can handle virtualizing a nas device do it, we all need to do our part in protecting the environment. I personally don’t care much about the electric bill (my network is more important) and I help the environment in other ways so I have dedicated servers.  On that note I have 6 physical servers running 24/7 plus at any given time there is usually a light on some where in my house (my wife and I suck at conserving power) and the electric bill is only around $150-175 per month.  I don’t think that’s a bad price at all especially since all power saving and efficiency settings on the servers are turned off. 

That’s my 2 cents; I wish some one told me what I just told you before I bought my core.  It was between the one I have and a quad core but I read the wiki which said a p4 or something and I figured the AMD 5000 would be enough.  I really think the requirements in the wiki needs to be adjusted.  I don't understand how you can run this thing on a p3!!

Thanx klovell for the replay!
Think it's the longest replay I ever got in a forum!!!
Got your point, to have a smooth running system when you running media applications you need at storage solution that meet your expectations regarding  performance/latencies. Flicking movies and long start times is not anything that I wish.

What you also underlined is that got NAS performance needs a lot of CPU!
Hopefully will I unlock the forth core on my 3x core cpu. But come on.. 4x 2.MHz...  wouldn't that be enough ? For the core server! I would lie to be able to stream to at least 4 MD at the same time.
But to clarify ... I plan to use my HP Proliant 150 ML as host for the virtual machines. I know it's not a speed demon. But I hope it will be enough for 2 or 3 windows servers + FreeNas.  I have a 4 core 2.2 MHz AMD Opteron and 4 GBit of ram.

Please advice and share your experience !


Btw I have trouble to get in the gadgets in the rack cabinet. I got 80cm (31.5") and the dell keyboard drawer I got is for a 90/100 deep server rack.
Anyone that know where to get rack bits 'n' pieces?

Got some new gadget to my new LinuxMCE system!
Manage to get a cheapo UPS and autoloader[Powervault 120 DLT] today.

Just wonder if there is any good backup software for linux that I could use! Like retrospect? Would like to have the autoloader with the core server!
Is there anyone out there that already tried it together with a core server?

My server building project have been halted because I can't find any PSU fint my chassi. Need one where the air can pass through the PSU.
_{[From the side with the modulare cables are to the backside. Have a look at pic to undersand how the air passes through the chassi.]}

Need to have a meshed PSU or a dual 80mm fans  PSU. Seams that the have disappeared from the market.

Any Ideas?

a quick question!

I got a LG 50PS3000 with a simplink [ http://www.hometheatermag.com/hookmeup/208hook/ ]
Do anyone know if its possible get simplink to work with LMCE so you could use the tv remote to play/FW ??

Installation issues / LinuxMCE+DSC 5589?

« on: April 13, 2010, 11:37:52 am »

Just currious have anyone installed DSC5580 voice/X10 module with linux mce?
would be nice to use the alarm for voice confirmation!

like "Dimming up 100% in bahroom"
just need to put amped speakers round the house 

BTW Does anyone know if you can show room temp in the alarm panels?
(from 1wire sensors or similar)

the ESX server is basically an windows server sandbox.

the reason that I choosed a standalone server for 1wire was simply tha tit was not supported by linuxMCE and that I don't want to put all eggs in on basket 
Plan to build a massive 1wire system that feed an database. So if I need to take down the core server will I loose data from the 1wire micro lan.

Think I put all disks in the esx server and make a share on that server.

any opinions?

I would like to keep servers to a minimal because of high electric bills and the environment impact. They will be running 24-7  
So the best option to have a separate server for storage?

Then will i  have one server for 1wire, one for ESXi and one the LinuxMCE core server plus one for storage!

Is't there a way to use the core server as NAS with ISCSI?
Or should I run FreeNAS virtual on the ESX server?

Please advice!

Hi
I have followed the progress of LinuxMCE for a couple of years now.I am a totally noob when i comes to Linux so i have't really got in to LMCE. But now I can hold back my eager to learn how to build any more. I would like to try  put up my first complete system. I'm building a new house so I can do all adjustments that's needed to totally automate!! (as much as possible) Will use about 30 X10 devices. [DIN sockets] to start with. I got me a full hight Rittal Rack, were I can  put all the gears.

So I finally will start to build my 1st Coreserver. 
Now would I need you gurus to give me some advices and input how to build an Ultimate core server!

To start with have bought a Koolance 4u rack chassi. [watercooled]
and pre orded the following mobo Gigabyte GA-M720-US3 via an AMD Athlon2 X3 435 2,9Ghz, AM3,

Do anyone any experence of this CPU and mobo togeher with LMCE?

I'm not sure what kind of storage I gone use. I planned to have an parallel windows environment running on an separate ESXi server.
So It would be great to have an ISCSI solution.

Is it possible to integrate FreeNAS in LMCE?
And then from the ESXI server run the virtual disks at the core server?
Or maybe it's better to have a separate storage server/solution?

Please advice an linux noob as me!
