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

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 (lnz@dandelion.com)
	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
