Re: Veritas Volume Manager

[John DeFranco <defranco@cup.hp.com>]

I actually think its also really (relatively) expensive for Linux as 
well. Veritas is not in the habit doing things for the good of the 
community. Whether it worth it or not really depends on what your 
requirements are. Certainly the Veritas product provides a much 
cleaner solution in terms of including the mirroring portion within 
the vm itself (although depending on what features you want it will 
be an extra cost as well). This is better than using lvm on top of md 
(which I do at my site). 

These other products (lvm and md) are free but that also means if you 
have a problem who knows when it will be addressed. Same is true to a 
certain point with Veritas as well.

I have done quite a bit of work with VxVM on both Solaris and HP-UX as 
well as work with md/lvm. Both have their pros and cons. If you don't 
mind the cost and feel the current tools are primitive then VxVM 
might be worth it. However it you just want a reasonable 
mirroring/raid solution md/lvm might just be ok.
