Thanks! > =E2=80=8BWe've had great experience with LSI (now Avago) 9211-8i and 9211-8= e controllers. These use the older LSI2008 chipset, fully supported by the mps(4) driver under FreeBSD 9+. We use these in 24-bay, 4U SuperMicro chassis with a local motherboard (all-in-one server). And in multi-chassis setups with 90+ hard drives (2U SuperMicro chassis with the motherboard and HBAs connected to 4U SuperMicro JBOD chassis). --=20 Freddie Cash fjwcash@gmail.com
