HP ProLiant MicroServer

If there is a prize for a thread that gets more than 200 0000 page views, then the OP should get it:-)
 
Gah, remind me to never do a apt-get dist-upgrade if everything's peachy. Wrecked teh_whole thing.
 
Need some advise here guys, I got my server yesterday - popped in a bootable flash Ubuntu 11.10 - but it doesnt detect the HDD ?
I have taken it out and formatted in Win to NFS - but to no avail.. halp :'(

Make sure that the drive caddy is inserted all the way in and that it is clipped in place, also try out another drive bay. If that doesn't help then check that all your cables are securely in place and maybe just re-insert them to make sure. If the drive is being detected (which can be checked in the bios) then there is either something very wrong with that copy of Ubuntu or there is user error :)

I cannot see the drive in BIOS ..fk checking diff bays now
**Solved it
SATA cable wasnt seated properly.. dammit

Also got mine. I need to get 2x2tb drives to mirror in raid, but need to wait a few months. Do u think the following is likely to work?
- get up and running so long on the supplied 250gb
- pop in a 2gb later and duplicate the 250gb onto the 2tb
- remove 250gb, pop another 2tb in and mirror the initial one onto the new one
 
So thanks to all the guys that bought. You've pissed off my wife as she says there isn't enough room in the house..
 
ah man, completely forgot to message you over the weekend!!

hopefully they will have another one soon
 
Aw cr*p I went away for the weekend and also completely forgot about this...

Yep, unfortunately to run xbmc on iOS, the device must be jailbroken which isn't an option for the new iPad yet. There is the xbmc constellation app which is cool but really just a glorified remote control.

Plex on the other hand is a full on app which blows all the other video apps out the water. Video is silky smooth and I am able to stream 1080p video to the iPad on my local network and can also watch from anywhere (which is nice having, but being limited to 512kbit upstream on my adsl line, not ideal in this country).

New greenpois0n can JB iPad 3rd gen on 5.1.1 ;)

You have to do RAID off the bat, else it won't work. Keep the 250GB, add in the 2TB mirror array for your media. There's little chance the 250GB will fail anyway thanks to the single platter and 7200rpm rotational speed.

That's the bitch about RAID. I also want to invest in more drives, but need to build a 4 drive array and can only get it setup up once I have all four drives.

If you want to do mirroring on two drives however, there are other options. I have done a setup that mirrors data just by using rsync to schedule daily backups to a separate drive. This kind of has it's pros and cons, but one pro is that if you screw something up or delete something unintentionally you know that the data is untouched on the backup drive until rsync runs again.

What about unraid? There are a few users of it in this thread. You just add drives as you get more and it grows.

Why not use RAID 5? You can build the array off 3 drives and add as time passes. The space available would be 1-1/n where n is the number of drives available. So three 2TB drives results in: 6-1 = 5TB of useable space. The rest is for parity. All you'd need is identical space drives with the same rotational speed and a good UPS system that switches onto battery backup almost immediately. And all you'd have to do is add in one drive every two to three weeks to make up for the parity distribution and to allow the array to scale accordingly. Once you reach something monstrous like 24TB then it'd probably take two months to scale up the array.

The only caveat is that you're still only allowed one drive failure, so I'd only build a RAID 5 array to six drives for less complexity. RAID 6 can tolerate two failures, so that'd allow me to go up to ten 2TB drives for a total of 18TB. RAID six leaves you with more flexibility, but requires four drives from the start. I'd also only use these arrays with dedicated PCI-E 4x cards, as the rebuild is a taxing and time-consuming process. Having dedicated hardware do it in idle time is better in the long run. Having said that, a motherboard without RAID add-in cards that is just used as a server would do the job just as well, with a little performance deficit. You'd be limited to RAID 5, but that's enough for most home media servers anyway.

I like that idea, but again you'd need proper hardware to do it and the caveat is that it stores information across one, two or a group of drives as opposed to an entire RAID array. The benefits are scalability and rebuild time, but the write performance differs according to which drive the data is stored on and how fast that one is. unRAID is a great idea in a dedicated server that's going to be in use for years, not so much for desktop use or for HTPC.

I'd say for desktop use, mirrored RAID is a good starting point with two 500GB drives as the mirror and other drives in a higher level of RAID connected to a dedicated card. I'll be going for a mirrored setup for my next machine if I find that SSDs wont cut it for me. Perhaps Trim support gets implemented in RAID in the future, but for now its not as viable.
