Greetings all;
Does anyone have experience with this controller card?

Specifically, whats my chances of moving an existing software raid10's 4
Samsung 1T's to it,
and then attaching 4 more 2T drives to it too, to create a separate 4T
raid-10 for amanda?
Without any data loss if possible?
I don't have any experience with this one. I don't know what
SATA chipset it is using, but there aren't many that the kernel
doesn't already support.
That said, it is a straight SATA3 board, not a RAID board, so
there will be no difficulty in moving mdadm, btrfs or zfs RAIDs
over to it.
I would point out that you can't actually fit 16 x 3Gb/s worth
of bandwidth over one PCIe lane; if this is v1 PCIe, you have a
total of 250MB/s available. That's probably fine for four
spinning disks doing backup duty.
Here's a 4-port model with named PCIe v2 support and a
recognizable SATA chipset, for slightly less money:

I looked at that one too, Dan, but I've filled up the back panel with usb
breakouts and it will
take a major re-arrangement to clear a pic-e slot. This mobo only has two,
and another drive
controller like this 4 port is already in the other slot. Not saying it
can't be done, but
will be a pita to do. There is also a 6 port onboard controller that I might
be able to use
for the 2nd raid. With a boot drive, and a buffer drive for amanda, and 4
2T's on it that would
fill it up. I've got a usb3 optical drive that burns a dvd now and then so I
can do away with the
sata drive if push comes to shove. Or the accessory card for the /home
raid-10 is a 6 port with
2 empty sockets.
Can I make a 2nd raid 10 from two separate controllers? 2 drives on the mobo
controller and 2 on the
plugin controller? I'd think that could lead to mix-n-match problems given
udevs penchant for
shuffling drives.
Too many options......
