As title mentions "ZFS: LSI on HP NL40: is there a way to get into this BIOS?", I'm not sure if the known bug means you cannot get into BIOS at all or not always.
Reason: I like ZFS but I'm not that much impressed about performance untill now.
I might consider configuring SSD RAID for 1 ESXi. Single point of failure now would be my NAS, with ESX that would be the ESX-server (have only 3 esx-es of which mostly only 1 runs so redundancy would be the same).
