Hi.
What Serial ATA RAID controllers are supported by Proxmox?
I own a Adaptec 1210SA, but I realized that it is a software RAID, not hardware, so it is not supported by Debian and Proxmox.

Could you help me please?

Thank you very much!
Bye.
 
3Ware cards work. I use a 9650SE-8LP and as long as you carve out a partition smaller than 2TB you can install PVE on it just fine.

Adaptec 5805 works perfect (and similar).
I would go for this.

Is the 3Ware Escalade 8006-2LP supported?
It has two Serial ATA ports...

this one has no BBU backup cache. this is very needed for performance so I do not recommend this for a virtualization server.
 
Using command lshw will show my RAID controller as a
3ware Inc 7xxx/8xxx-series PATA/SATA-RAID

I found an interesting article at the www.3ware.com website:

General performance tuning tips:

For Linux kernel 2.6, If you enter the following command:

blockdev --getra /dev/sda
it will list the current read ahead cache settings for block device sda.

If you enter the command: blockdev --setra X /dev/sda

i.e.

blockdev --setra 16384 /dev/sda

it will set the read ahead cache to 16384. (Note: 16384 is just an example value. You will have to do testing to determine the optimal value for your system). The OS will read-ahead X pages, and throughput will be higher.

After settings this parameter my disk became 49.84 % Faster !!!
Because my default read ahead cache was much less !!!

I did check the speed with: hdparm -tT /dev/hda
You need to have hdparm package to test.
 
hdparm is not a good tool for real-world performance, it only looks at burst read rates of the drives/array. You should try bonnie++ or iozone to get a true feel of how those changes will effect a system that's doing more then sequential read/writes..

Cheers

I think you are talking about this http://www.3ware.com/KB/article.aspx?id=11050 A very good tip ! Read the PDF file at the end of the article. This helps testing your controller. this performance tips are not only for 3ware equipment. It helps you in general improving your I/O.
 
yes, that's a great card. we use several 5805Z here in our test lab which are just 8 port cards.
they got a bit hot but their performance is great.
