I've been pounding many Gigabytes worth of concurrently accessed SSA disk subsystems for quite a while without any failures or hiccups. While I haven't seen any of Sun's ( or whatever third party ) LVM stuff, HP's version is a little crude. The only draw-backs I see, if any, is that HACMP can be difficult to set up, is definitely proprietary, and the supplied DLM is limited ( at least in 4.1 and I believe 4.2 ) to 255MB memory. I've configured over 100k PCM locks over two distinct "sets" of instances across nodes and haven't reached 50% of this limit yet. -Kevin -- remove the x for email response Scott Cote wrote in article <35A2D814.8C7C0E4B@contractor.net>... > Please save me from marketing thugs. > > I am setting up a brand spanking new data center and am trying to make > an informed decision as to what platform I am going to run OPS on. > Platforms under consideration: > > Sun ES450 > HP K box > IBM rs6000 F50 > > I don't want to even consider an NT class machine (I am a UNIX bigot). > > If you have any advice regarding hardware (server/storage/network) - I > am all ears (eyes actually). > > Thanks, > > SCott > > Scott Cote > scottcote@contractor.net > (972) 672 - 6484 > >
