I have EMC's Powerpath software installed to give me multiple paths to the disk subsytem in case of controller or cable failure.=20 This configuration has served me well but is now about to be End Of Life'd by Dell and I need to grow the storage. There is obviously quite a price premium to pay for this sort of kit so I was hoping to find a cheaper solution for the future. I have seen the Nexsan ATABEAST which is a 16TB ATA array with dual fibre channel controllers. It seems to be well liked and is reasonably priced but my concern is how to achieve multiple paths to the disk. How would you recommend achieving a highly available configuration with this sort of disk subsystem? Also, am I correct in thinking that the maximum filesystem size with RHEL 3.0 is 2TB? Is it possible to get over this limitation with LVM or some other method? Any advice gladly received.
