Correction: the SiI3132 are on x1 (not x2) links, so my guess as to the aggregate throughput when reading from all the disks is: 3*150+100 = 550MB/s. (150MB/s is 60% of the max theoretical 250MB/s bandwidth of an x1 link) And if they tuned MAX_PAYLOAD_SIZE to allow the 3 PCI-E SATA cards to exploit closer to the max theoretical bandwidth of an x1 PCI-E link, it would be: 3*250+100 = 850MB/s. -mrb _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
