###Replace the LSI SAS 2008 controller with a Highpoint Rocket 2720SGL.
This Rocket 2720SGL adapter contains a Marvell 4.0.0.15 BIOS. This BIOS won't spinup the PUIS/POIS drives.
That is not a problem because the Marvell 4.0.0.1528N open source Linux driver make does create a mv94xx.ko kernel module that is able to spinup the PUIS/POIS drives, also behind a HP SAS expander V2.08. Now there are /dev/sdXX devices available in Debian.
As a result the Marvell BIOS can be disabled, which shortens boot time.
Note: the Highpoint Rocket 2720SGL is not a RocketRAID 2720SGL, the RocketRAID contains a Highpoint BIOS, the Rocket contains a Marvell BIOS.
