AACRAID driver for FreeBSD and Mac OSX
This driver supports the following controllers:
- Dell PERC2/si
- HP NetRAID 4M
- Adaptec 5400S
- Adaptec 2120S
- Adaptec 2200S
- Adaptec 2410SA
The driver in FreeBSD is pretty much feature complete. All new features and
bugfixes are submitted directly to the FreeBSD CVS tree, so please check there
for the most recent driver. The
RELENG_4 driver is a bit stale
and I'm working to get it up to date. Please feel free to email me with any
questions or bug reports.
An experimental AACRAID driver for OSX is available here. It provides basic support for the cards
mentioned above. Known issues:
- Booting from an array is not possible. Making this work is a significant
task that involves writing a Forth driver for the card, along with extra
magic in the driver to support the OS at bootstrap time.
- Energy Saving features of the OS are not supported. If the OS puts the
system into low-power or sleep mode, it will quite likely confuse the card
and create havok once I/O is resumed. I'm working on this.
- No management interface. There is no way to create or monitor arrays.
You'll have to create the array using a PC and then transport the array
- Please remember that this driver barely qualifies as an 'Alpha' release
right now. If it interests you, please send me an email. I will also be
posting the source code to it soon.
