Someone asked about a large scale "success story" recently. This
from lkml; unfortunately they didn't hint what their application
is.

10 disks 36GB each divided as following:
0 140956 5 Drives Write Thru
1 140956 5 Drives Write Thru
9 of these disks are handled into an external cabinet
1 disk was into the main processor box.
When file system created:
8 file system of 36GB each. This is an example of
File systems hadled by Pack 2:
Disk /dev/rd/c0d1: 255 heads, 63 sectors, 17968 cylinders
Units = cylinders of 16065 * 512 bytes
Device Boot Start End Blocks Id System

Swap area:
4 partitions of 100MB each
Special used drivers:
DAC960 2.0.0 Beta 4 from www.dandelion.com
Special thanks to Leonard N. Zubkoff ([EMAIL PROTECTED])
for the quality and reliability of this new driver.
Special used software:
fdisk v2.8 caontained with DAC960 driver
MTX 0.07 package from www.dandelion.com/Linux (again Leonard)
Tests completed without problem to report:
Save of 40GB on DLT tape and retrieval
Fill up a 36GB file system, copy it on another file system,
compare both file systems, delete target file system contents
(rm -r)
Unplug a disk meanwhile system copying. Replace this "damaged"
disk by a new disk.
Power off the system meanwhile heavly used.
Recover time: 30 minutes for a 36 GB file system full of data.
(there are 8 file systems)
Hardware pending troubles:
The external cabinet has room for 9 disks. The 10th disk was
installed into the main processor box.
All disks were linked together using eXtremeRaid 1100 channel 1.
Unable to prepare the System disks from the 2 5 disks packs.
We got all the time: disk nn goes offline
We linked the 9 external disks to the eXtemeRaid 1100 using
channel 2 meanwhile we keep the internal disk on channel 1
Channel 3 is free.
Software pending troubles:
FDISK 2.8 (dandelion version size 158979)
Accepted the above geometry, but is not able to reread it.
Declares all the time:
The number of cylinders for this disk is set to 4942.
No impact on mke2fs as long we know the declared disk geometry
(write that on paper, keep it in a safe place)
This system is working perflectly since 5 days.
Should you need additional or detailed information, please feel free
to e-mail/contact me.
