[Gluster-users] GlusterFS Hardware Recommendations

2010-06-17 Thread Andy Pace
Hello all, new to the list here. Figured I'd hop in to get some insight/opinion on the hardware requirements of Gluster in our environment. We've been testing Gluster as our shared storage technology for our new Cloud product we're going to be launching. The primary role of the Gluster infrastr

Heh sure although we took a circuitous route to get to where we are. To start with I recommend using DRBL (diskless remote boot linux). It's a well maintained project and will save you a lot of initial headaches of creating initrds compiling etc. http://drbl.sourceforge.net/ It's nfs based bu

We have a similar setup booting from gluster where it loads the os into a ramdrive, but there are concerns as you write logs etc since it can start to eat up your ram. there is an article from slashdot that had an interesting approach (look under "setting up storage" halfway down): http://blo
