If you really want performance, the LVM should be stripped across RAID Arrays. And make sure you use multiple controllers. (i.e. in the DS6800 there are two controllers, each has half the cache. If you do LVM across both controllers, you have the potential of using all the cache, not just

I see that you've gotten some excellent replies already. In our shop, we originally avoided striping on the Linux side (that is, within LVM) because we wanted to avoid a plaid or cross-hatch when the data hit the physical media. Some of us now believe that #1 that's not really a problem and #2

One other thing... I said you can't exert any control over the network using this technique. In so much as there are files in /proc that can be written to (to change certain kernel parameters) you will be able to write to them just as easily over the network (unless you mount read-only or change

Hello Kevin, I recommend that you stop using EVMS and start using LVM2. The direction with SLE11 and going forward is to use LVM2 as the logical volume manager and cLVM2 as the clustered filesystem aware volume manager. You will not need to reinstall SLES10, LVM will be able to see the LVM
