Re: [LUG] mirrors and raid

[Bill Wilson <bill@xxxxxxxx>]

IBM support most Linux versions and provide hardware RAID. We have lots of
sites running this. BEWARE when setting up RAID that the controller is just
as likely to fail as the disks. To be safe 2 controllers mirrored. We use
Red Hat which IBM provide drivers for see IBM site for supported versions
of Linux. As a matter of course we presently recommend IBM for all our sites.
Bearing in mind that IBM servers  come with 3 years on site maintenance from
IBM and start at less than £1000 they are as price competitive as any. I
accept that personal users may not see the benefit of this but if you are
using it for your business then it works out well
