Finished, operational, everything done.

I leaning either a bad ram stick on the card or a faulty card altogether.

It sucks really bad, because I bought this in the States but Im now in argentina. So I need to take it to the importer to send it back, so it might take some time, but is so frustrating.

Thanks for all your help I greatly appreciated.

I will do that, I know it should be better with the hardware raid, but Im running out of ideas and there is little left to try.

Look what areco support sent me:

“and it is normal that software raid is much faster than hardware raid. because software raid use system resource and system have much faster processor and more memory space.”

I don’t know if it is funny or sad. A dedicated dual-core raid card with 4gb of ram being slower than a software raid seemed wrong hehehe.

[Tomas Bocking]

Is not giving a simple play of 1080 dpx, there is something seriously wrong with the setup, but I cant figure it out what it is.

I’m about to try software raid next, since the have to do some work and then ocntinue testing, but it driving me nuts!

Thanks for the help,

I’ve tried both xfs and the last version of ext4 tools that would allow over 16tb volumes with pretty much the same results.

Any ideas?

[Tomas Bocking]

Yes but the system was not showing these symtoms when working connected to a san.

I’m having problems now that I have put a raid card in and tryng to make it work locally.

Any insights about the raid creation process?

Thanks a lot

Margus, Joakim and Paul thank you so much for your help, but I keep having performance issues, very inconsistent playback framerates.

Lets see if you could identify anything I might be doing wrong:

Hardware:

Dual Xeon
Display card fx3800
GPU card: fx5800
12gb ram
Areca 1882x
11x 2TB Seagate Barracuda 7200

RAID info:
Raid level 5
Stripe 128k (this is the max it will allow)
Block size 512
Cache attribute = Write-back
Write Protection = Disabled
Tag Queuing= Enable

Steps to create the file system
Parted:
Partition table GPT
mkpart primary 0.0TB 20.0TB
create filesystem: mkfs.xfs -b size=4k -l lazy-count=1 -d su=128k -d sw=10 /dev/sdb1
Mounting: mount -o inode64 /dev/sdb1 /media/LocalMedia/

Is anyone able to identify something that might be giving me such a crappy performance?

Thanks in advance and thanks again for everyone who collaborated in this thread.

Thank Margus, yes I have been reading the forums, looking for information.

Wht I found on review sites is that the performace of ext4 seems better than xfs.

I KNEW that xfs was a must for video editing, has anything changed regarding ext4, is it better than xfs?

Thanks

Thanks Dan, got the dvd.
