Linux Kernel: SuperTrak Driver
Promise SuperTrak SX6000 Native Kernel Driver
We bought a Promise SuperTrak SX6000 card with the intention of using it to run
the main file server for VectorStar
Networks. We found Promise's supplied "linux kernel driver" to be much less
than we expected. We needed a native kernel driver that would let us boot
directly from a RAID array. So, we took their
188.8.131.52 source code
and turned it into an actual kernel patch. PLEASE be aware of the following:
Keep in mind that you're using this completely at your own risk!
- Promise's SuperTrak driver uses its own funky I2O code.
- We have made some minor efforts to clean this code up to remove conditional
sections for 2.2.x and 2.0.x kernels. Other than that, we haven't really changed
or optimized this driver in any way. It could use a lot of work!
- This driver doesn't have spectacular performance. Our own testing shows a
4-drive RAID-5 array (with 32mb cache) to be 15% faster than just a single drive
running on an Ultra DMA-33 channel.
- Promise does NOT support this patch. Hell, they don't even support their own
kernel code release!
Okay, you've been warned. :)
