i use 3ware if you are using a lot of drives, i use 8-12 in a raid 5 config, and its pci-x or pci-e you are better off using the 3ware over linux RAID, because with linux you'd have to get a expansion sata pci-x/e expansion card anyways, and thus you may as well get the 3ware with hardware raid 5 or even 50 built in. 3ware also have linux command line monitoring and admin tools, also you can get battery backup modules and the top 3ware in the line i use has a 512MB cache (with battery you can use it for wrtie cache), and this definitely can speed things up depending on what your server is doing. I have about 6 3wares installed now, all have been 100% perfect. I used 3-4 promise's in the past, they are slow, and don't have decent linux command line monitoring and admin. -tl On Sun, 2007-03-04 at 22:28 +0100, Anders Norrbring wrote:
I'm looking at building a SATA II RAID-5 system, and I'd like to get some thoughts on controllers since there are a multitude out there.. I'm going for either 4 or 8 ports. The rig should be run by a 10.1 x86_64 system with dual opterons.
The manufacturers I'm looking at are:
Adaptec Highpoint 3Ware Promise
Can someone with knowledge about these tell me the pros and cons with each of them?
