Hello, I want to know if geom_raid1e support raid10e level too. The difference between them is that 1e duplicates the 32-64-128-whatever block data size in all n disks in the raid1e but raid10e only between n/2 and n (a try to show it below), making raid10e bigger and more flexible than plains raid1/raid1e or raid10 respectively.
In raid1e: Disk D1 D2 D3 D4 D5 Block a1 a1 a1 a1 a1 Block a2 a2 a2 a2 a2 Block a3 a3 a3 a3 a3 In raid10e: Disk D1 D2 D3 D4 D5 Block a1 a1 a1 a2 a2 Block a2 a3 a3 a3 a4 Block a4 a4 a5 a5 a5 In these examples, with block size of 128KB, raid1e will survive to fail of 4 disks and stores 128*3 = 384 KB; raid10e will survive to fail of 2 disks and stores 128*5 = 640 KB. In some literature, raid10e duplicates between 2 and n disks. --- --- Eduardo Morras <emorr...@yahoo.es> _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
