I have been a long time Gluster fan however I gave up on it about a year ago when it just was not working out for xen, so I moved to NetApp. I now am looking at offering storage as a service and NetApp just can't scale or offer the price point needed. I would love to hear feedback from users who are running large amounts of data on GlusterFS. I want to scale to hundreds of notes, but starting small at first. Looking at 5 cites with the following: 8 servers: Dual Xeon X5680 3.3 GHz 3Ware 9750-8i 6 Gb/s 32 2TB drives RAID 6 + hot spare Mellanox MHGS18 10 Gb/s Infiniband Each server will have raw 60 TB of space and two servers will be unified together for redundancy. Pairs of servers will be distributed into one 240 TB volume in each city. The plan needs to scale to 4 PB in each within 1 year. ><> Nathan Stratton CTO, BlinkMind, Inc. nathan at robotics.net nathan at blinkmind.com http://www.robotics.net http://www.blinkmind.com
