- Even for highend RAID's there are lots of reasons to use LVM/EVMS: * load balancing across multiple scsi-channels (not implemented yet) * Dynamic partitioning * Volumes spanning multiple physical dev

- But how about performance? Aren't these things supposed to be handled by the hardware? It's the same thing as for soft vs hard RAID. Hard should be faster (but, yeah, soft is easier to play with). --

- There is a performance penalty, but if you're using LVM just for partitioning it's very small. (I believe ca 4% if you're using large extents). I'd assume the penalty for doing striping is approxemat

- That is referred to as hardware RAID because most RAID card devices use an ASIC programmed to do ONLY that. Think of it, if you like, as a RAID appliance. :) -- Austin Gonyou Systems Architect, CCNA
