Apple Video Environment -SLOW

[robertdalco]

Max I get on large video files is 30MB/s. As a NAS or iSCSItransfer. Was thinking I should get between 60 and 90 MB/s -preferably on the high side

open test.log with a text editor and find this line

hdparm -t

you should find a line like this one ( but with your number )

Timing buffered disk reads: 208 MB in 3.02 seconds = 68.95 MB/sec

post here the xx.xxMB/s you have

What MAC OS are you running ?

I have two different postings under HDPARM

hdparm -t /dev/sda *----------*/dev/sda: Timing buffered disk reads: 60 MB in 3.09 seconds = 19.43 MB/sec

hdparm -t /dev/sdb *---------*/dev/sdb: Timing buffered disk reads: 1014 MB in 3.20 seconds = 316.85 MB/sec

This is telling me what? Are there any key setting I can change?

This is telling you how much MB/s Open-E is able to obtain directly from your system , every time Open-E boot it does a series of test and put it into file test.log so with this information technician could help you.

Could you send me PM(Private Message)your complete .gz file , I will look at it because I don't know why you have sda with so much slow transfer , sdb is ok , do you have some external USB Drive or any other hard drive than the one connect to your ARECA Raid Card?

One RAID set carved into two volumes. sda is XFS formatted and sdb is NFS formatted. Does open-e have any volume format issues?

Without logs file I can't do nothing

Open-e will format the disks to xsf when you create the volume group

sda is probably the USB dongle and ranges from 20-30MB/s in our systems. sdb is probably the first SAS logical volume.
