JBOD, ha, this is difficult to found in those storage vendors. because they changed the meaning of JBOD. check from http://en.wikipedia.org/wiki/JBOD#JBOD the main points is JBOD do not need any raid configuration which is descripted in the guide.
While for HP servers you need to do is order H221 HBA card and directly connect the D2000 enclosure. in my case, it is DL380G8, H221 HBA, and D2700 enclosure.
These controllers do not support a non-RAID, JBOD mode. They cannot present disks to the host directly. Each disk must first be included in a Logical disk. You can create a single logical volume for each disk you have and give this to ZFS. Performance should be equivalent. However, it means putting header information onto the physical disk. If your controller fails, you must use another MegaRAID, configured exactly the same. And there is not guarantee that another SAS or SATA controller will see the data correctly and present the volumes in a way that the zpool can be correctly constructed.
MPIO solution: no native DSM from HP.So just using Windows server 2008 r2 native MPIO dsm,
