Please note that "support" in this case refers to what Sun offers or will support. The Marvell controllers are like any other SATA controller... you could put 16GB SSD SATA drives or 1.5TB drives, technically speaking. > Do you have to run some form of SW RAID (mirroring or such) on ZFS ?

As far as how to actually leverage Thumpers rely on Google. You'll find articles on BigAdmin, Sun BluePrints (sun.com/blueprints) and a wide variety of blogs. > Would anyone know what is the total useable capacity for a 48 bay 1TB drive > Thumper server? > I run my Thumpers with 512GB drives (24TB raw) and typically arrive at a usable RAIDZ2 pool about 20TB usable. What you arrive at usable will depend on how you choose to layout your pool. You could do 11 pairs of mirrors, series of 4 11 disk RAIDZ (Single Parity, think RAID5) or RAIDZ2 (Double Parity, think RAID6), etc. Its up to you. > Any pointers will be greatly appreciated. > We are missing studies on the performance consiquences of different pool configurations, so your not going to find a white paper with benchmarks for different configs. Therefore, take a day or two to play around with diffenent pool configs and benchmark your workload if you can. Otherwise, you can find several examples or scripts of how to use a single mega-pool configuration. Happy ZFS'ing. benr. _______________________________________________ storage-discuss mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/storage-discuss
