Re: ASM and RAW Devices on RHEL 4

Thanks Pete.

This is a very usefull document even though it doesn't provide any performance benchmark figures. As far as I understood, reference ASMLib implementation for Linux gives two things:

1. Managebility advantage - simplified/automated/stable discovery process.
2. Reduces overhead of managing file descripts. Another potential benefits (IO intelligence, hints, write validation) are only available with storage vendor's specific ASMLib implementations which are not available yet (are they?).

Thanks again,
Alex

I checked with the ASM product management team and they're looking into getting that out somewhere so people can see it. For now, I'll send it to you offline - I don't think we're allowed attachments on this list. Anyone else who wants it let me know and I can send it to you as well.
