Last time I checked, but I could be wrong, Broadcom's RAIDCore solutions
are FRAID. They are very, very high-end FRAID designs (PCI-X, 8 channel),
with lots of software IP for rebuild options, etc..., but still FRAID. I've
never personally tried the cards because they aren't any cheaper than
3Ware solutions. But they claim integration tools with Linux's LVM/MD
(I have no idea how these work) and should have at least ATA/SATA
channel drivers for just a bunch of disks (JBOD) as with any ATA/SATA
controller.
Luckily Broadcom's new IC for either PCIe x4 or PCI-X 1.0 is an intelligent,
MIPS-based hardware solution for either SATA or new Serial Attached SCSI
(SAS). The pricing should be similar with the controller being under $60/1K
quantity, but finally bring some serious performance to the table (along
with up to 768MB of battery-backed DRAM).
