Our hardware vendor is HP and we are looking to purchase HP DL380 G9 servers. Previously we tested HP DL380 G9 servers with Smart array P420i. We were not able to configure the RAID controllers in by-pass mode. Thus, we configured each disk in RAID 0 config and we have multiple RAID 0 arrays for each disk. However, I understand that ZFS needs to "see" and manage the disks directly and not through RAID controllers. I have checked the FreeBSD hardware support matrix but HP H240 HBA controller is not listed. Can someone recommend me a "dumb" controller similar to H240 HBA which allows bypass mode so the ZFS can manage the disks directly. HP has the following "dumb" controllers which supports pass through mode. 1. H240 2. H240ar 3. H241 Any ideas and recommendations are greatly appreciated. We are under time constraint so we are unable to buy 1 server to test. Thanks! -- Regards, Ang Wei Shan
