We have tested ATTO Diamond FC Disk Array with Networker 7.0 and Veritas 
VxVM/VxFS for disk backup.  When creating the VxFS partition as "file device", 
you need to set the file system >2GB setting.  Networker shows the volume is 
full after 10% of disk utilization if ">2GB setting" is not on.

However, we found the use of VxVM/VxFS not necessary for diskbackup as 
NetWorker uses another file device volume once the first previous one is full.  
The need to dynamically resize the volume is not necessary.  Also, software 
RAID performs much worse than hardware RAID.

Does anyone know if it would matter if the File Type device is vxfs?
Anyone doing this now?

   Joel,

   We tried to do it on RaidZone machines (www.consensys.com) but trough
very unstable OpenNAS (RedHat Linux installed on Raidzone) we got rid of
this idea. So my advice before buy any hardware check filesystem
performance
and tolerance  carefully  with big files (>100GB).
