What sort of HA features does GFS have? GFS and Lustre are both free software, so base cost is essentially free, but configuring and maintaining are on your bill. GPFS, etc, have list cost plus support contract costs plus time. How does the installation cost (time) of Lustre compare to installation/tuning cost (time) of NFS and the cost (time+money) of the other cluster file systems. What about ongoing support costs? What does the supported version of Lustre from HP offer in terms of installation expertise and long-term support? -- Geoffrey D.
