I have the following layout A 490 with 8 1.8Ghz and 16G mem. 6 6140s with 2 FC controllers using A1 anfd B1 controller port 4Gbps speed. Each controller has 2G NVRAM
On 6140s I setup raid0 lun per SAS disks with 16K segment size. On 490 I created a zpool with 8 4+1 raidz1s I am getting zpool IO of only 125MB/s with zfs:zfs_nocacheflush = 1 in /etc/system Is there a way I can improve the performance. I like to get 1GB/sec IO. Currently each lun is setup as primary A1 and secondary B1 or vice versa I also have write cache eanble according to CAM -- Asif Iqbal PGP Key: 0xE62693C5 KeyServer: pgp.mit.edu _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
