Hi all, That's what i have, so i'm probably on the good track :)
Basically i have a Sun X4240 with 2 Sun HBA's attached to 2 Sun J4400 , each of them with 12 SATA 1TB disks. The configuration is - ZFS mirrored pool with 22x2 +2 spares , with 1 disk on Jbod A attached to HBA A and the other disk attached to Jbod B and HBA B - rpool mirrored with internal 146GB 10k 2.5'' SAS disks - 2 ZIL devices 32GB mirrored - 2 log cache devices with 64 GB each - multipath on all So far...? Just blazing performance for a workload that includes home directories hosting and Citrix XenServer VM's hosting all over NFS with link-aggregation (1Gbx2).
