"The kernel of the issue seems to be whether you want to use the features provided by the Linux kernel or the Solaris kernel. A few things quickly come to mind when thinking about each:

"Solaris gives us DTrace and ZFS. Linux provides GFS, DRBD and many options for high availability. Not strictly kernel-related, but requiring the set of tools that Linux has; Red Hat is also developing oVirt, which is basically a VMware ESX replacement. Both Red Hat and SUSE have their cluster services offerings, but so does Sun, in a much more limited capacity.

"Alright, we aren't going to get anywhere by comparing features. Linux definitely has more choice, but Solaris still has benefits. If you want an extremely high performance and high capacity NAS device, the Sun x4500 series (AKA Thumper and Thor) is where it's at right now. Because of ZFS, the throughput on these is stunning. Linux can’t touch its performance without something like ZFS, and your only other option is a NetApp. I bring this up because at my day job, we’re running three Thumpers. We frequently yearn for DRBD and other Linux technologies to build services that are more resilient without resorting to Sun Cluster, but running Linux on these is out of the question."
