See http://en.wikipedia.org/wiki/Xfs#Allocation_groups XFS was designed for big iron, where "big iron" from that time is commodity servers of today (4+ cores, 8GB+ RAM, RAID with lots of fast disks). During mkfs, you can decide how many allocation groups you want, and by the size of your partition, you decide how big a single AG is. And if your database spans lots of AGs, high parallelism can take place if it's well done. mfg zmi -- // Michael Monnerie, Ing.BSc ----- http://it-management.at // Tel: 0660 / 415 65 31 .network.your.ideas. // PGP Key: "curl -s http://zmi.at/zmi.asc | gpg --import" // Fingerprint: AC19 F9D5 36ED CD8A EF38 500E CE14 91F7 1C12 09B4 // Keyserver: wwwkeys.eu.pgp.net Key-ID: 1C1209B4
