Re: 1x 3ware controllers vs. 2x 3ware controllers

quoted

I'm looking at building what I guess you could call a budget NAS
array.  I'm looking to start with four 250MB SATA drives on 3ware
8506-4LP controller.  I eventually want to move to eight drives in the
box.  Is there any reason to expect that the performance of eight
drives spread across two 8506-4LP controllers is going to be any worse
then the same eight drives all on one 8506-8?

With the performance issues I'm seeing with the 8506-4LP's I have, I
wouldn't recommend them to anyone currently...

The thread on LKML from a few days ago about mke2fs -j and 8506-4LP says it
all, but basically and reasonable amount of I/O brings a Dual Opteron
system to its knees.
And by reasonable I mean copying ISO images from a usb2 drive to a raid 5
(4 x 250GB maxtor) or even just formatting a 600MB partition.

Should be 600GB but I haven't had coffee yet...

Mark.
