?AOC-SAS2LP-MV8 vs AOC-SASLP-MV8?
« on: October 23, 2011, 10:42:19 am »
Hi,
Do you have a favorite in between these 2 controllers: AOC-SAS2LP-MV8 vs AOC-SASLP-MV8??
Do they both support w7 64?
Any feed back from actual users of these cards? I am planning to add one of these to a regular MOBO and use it as a ''server'' for the house.

After, I would need something like that to connect from the controller to the HHDs:
Supermicro CBL-0097L-02 50cm IPASS to 4x SATA Cable

Getting ready to buy to start the build so I want to make sure I have everything right :-)

Thanks.

Just from the name you see the differnece between them! SAS2LP is obviously newer and faster than SASLP!
If you read the specs it verifies what I say (didn't you?).
I HARDLY doubt there is a SAS controller of any kind that DOESN'T support Windows 7 x64 (i.e. same kernel as Windows 2008 R2). Even if there was a doubt, then the NEW one (SAS2LP) is more probable to support it.

So if you find both at same price the answer on which to buy is like "eeeerm duh!".

Why get SAS controller if you attach SATA drives?

I'm using the SAS2LP version on my Win7 64bit and there is no problem that apparent to me yet(can't tell if it has any problem w/ SATA3 drives as all of my drives are SATA2).  Well, you do have to install drivers first though.  Win7 doesn't have native drivers for MV8.  Considering there have been report of the older SASLP incompatible w/ the 3TB drives.  I would use SAS2LP since there is hardly a price difference, unless you have some sort of technical limitation on your system, eg: PCI-e x4 slot and not x8.  The SAS2LP do use x8, while older one use x4.  Although technically(I think, as I hacked one in the past) PCI-e device are both backward and forward compatible in the slot.  Meaning x8 card will work in x4 slot as long as it fit and vice-versa.  Many mainboard now use PCI-e x16 physical slot even if the bus is limited.

I'm using an AOC-SASLP-MV8 Rev 1.0 with a 3 TB Hitachi 5K3000 drive. The latest drivers are needed for 3 TB support. I can provide a link if anyone needs it. I think I downloaded it originally from the AVS Forum though.

I use the SAS2 in my WHS2011 build with all SATA3 drives on it.  It's been running flawlessly since I installed it and it works great. 

I use these cables from monoprice.  Cheap and no problems at all.

Thank you all for the info, i ordered the sas2lp :-)

One additional question, can i use regular sata cable from the controller to the hhd or do i need mini sas cable like suggested by some of you?

There is no sata connector on the sas2lp-mv8 board, the only connectors are 2 Mini SAS 36pin (SFF-8087)connectors.  So, how are you gonna fit the normal sata on the board?

Ok, so i need to get this cable...  ;)
I will use the pci e x8 for the card and i guess the mini sas for the hhd connection, after that i am all set.
I will post my result when i am done.
Thanks!

Make sure you get the forward cable. The reverse is to go from a SAS backplane to a regular SATA connector controller.

As far as i know the first one has a 90degre angle, so depend on your config, internal organisation, it can be helpfull in the cable management... Also it s a 28awg which, based on my research, are better quality (thicker) but over 1meter long, i dont think you will see a difference. I ve got my cables from superbiiz for a few dollars more, after coupon code and no shipping so it s about the same price, but they are supermicro brand, maybe not a big diff, but it makes me feel better :-)

Thanks xylem.  I was wondering what the power connector on the very slightly more expensive cable offers; I'm not exactly sure what I would be plugging it into?

Why get SAS controller if you attach SATA drives?

Since no one ever answered this for you, let me chime in.

At it's simplest... one of these SAS cards can connect 8 SATA drives with the break-out cable. Most SATA add-on controllers support 2-3 drives, a few support 4 drives. Thus, running a SAS controller doubles your drives-per-slot (PCI-E/PCI). Plus, the break-out cables are much neater than random SATA cables. And, the SAS controller will do a lot of the processing work for you, leaving your CPU cycles free for something else.

In fact I got my own answer when I saw the card's price.
I thought it was expensive, but for this price you DEFINITELY get this and also have the option to switch to SAS disks if needed.
Plus all SAS controllers are more "professionally built" than mid-priced SATA ones.
So, great choice, I might even switch to one of those babies some time.

What does the power connector on this cable (http://www.monoprice.com/products/product.asp?c_id=102&cp_id=10254&cs_id=1025406&p_id=8192&seq=1&format=2) from Monoprice do?  Would it be wise to order it over this cable (http://www.monoprice.com/products/product.asp?c_id=102&cp_id=10254&cs_id=1025406&p_id=8188&seq=1&format=2) that doesn't have the power connector?  I realise that the first cable is also slightly thicker, but I would think that wouldn't make a difference over such a short distance of 1M.
