The linux sources appear to be in the "Alan Cox tree", and the
linux SX6000 driver is described as using an "i2o_block interface".
See:
http://groups.google.com/groups?hl=en&lr=lang_en&threadm=linux.kernel.E15vKkf-0006o5-00%40the-village.bc.nu&rnum=1&prev=/groups%3Fhl%3Den%26lr%3Dlang_en%26selm%3Dlinux.kernel.E15vKkf-0006o5-00%2540the-village.bc.nu
It's unclear if the monitoring tools will work with linux, though
(Promise's object-only drivers do not support monitoring).
The press announcement looks interesting: dedicated i960 processor,
parity HW, and up to 128MB cache RAM. However, for some reason, the
fact that they're hyping their ASIC bothers me. From the press
announcement:
SuperTrak SX6000 uses Promise Technology's best-selling Ultra
ATA/100 ASIC chip to automatically recognize and configure the
optimal speed for most Ultra ATA/100, Ultra ATA/66, Ultra
ATA/33, and EIDE drives. The ASIC has been used in more than one
million controllers and PCs worldwide through OEMs and
distribution channels.
Isn't this the same chip that's used in their low-end "raid"
controllers?
