I appear to be getting between 2-9MB/s reads from individual disks in my zpool as shown in iostat -v I expect upwards of 100MBps per disk, or at least aggregate performance on par with the number of disks that I have.
My configuration is as follows: Two Quad-core 5520 processors 48GB ECC/REG ram 2x LSI 9200-8e SAS HBAs (2008 chipset) Supermicro 846e2 enclosure with LSI sasx36 expander backplane 20 seagate constellation 2TB SAS harddrives 2x 8GB Qlogic dual-port FC adapters in target mode 4x Intel X25-E 32GB SSDs available (attached via LSI sata-sas interposer) mpt_sas driver multipath enabled, all four LSI ports connected for 4 paths available: f_sym, load-balance logical-block region size 11 on seagate drives f_asym_sun, load-balance none, on intel ssd drives currently not using the SSDs in the pools since it seems I have a deeper issue here. Pool configuration is four 2-drive mirror vdevs in one pool, and the same in another pool. 2 drives are for OS and 2 drives aren't being used at the moment. Where should I go from here to figure out what's wrong? Thank you in advance - I've spent days reading and testing but I'm not getting anywhere. -- This message posted from opensolaris.org _______________________________________________ opensolaris-discuss mailing list opensolaris-discuss@opensolaris.org
