LSI 9211 IT mode SAS card or SATA ahci card, preference? Opinions?


Recommended Posts

I am wanting to build a large backup only device, to sync all my other devices too and possibly make it a proxmox or vm box too (not sure, have no decided yet)

 

I was going to buy a LSI 9211 sas pci card off from ebay where they run about $50 or so dollars USD.  I did a few searches here to make sure it would work, try to establish difference between the H200 H310 H700 cards... and I found a couple thread where people say do not buy the sas card, and go with an ahci sata card and on motherboard sata ports instead? Seemed like 918 builds do not like sas controllers, but the 36xx models are ok since they have sas drivers? unless I misunderstood.

 

Hoping people with either cards can input their experience before I decide which way to go... they cost about the same, as a 5 sata port card is about $45 usd on amazon, and the sas card about $50 usd on ebay.  The only advantage I can see is the sas card supports 8 drives (plus your motherboard sata ports) and the ahci sata cards support 5 (plus your motherboard sata ports)

 

Is there a difference between the h200/h300/h700 series cards? or are all LSI 9211 cards the same for our purposes.

The ahci sata pci cards have to be non-multiplex (so no 10 sata port card if only 1 controller chip) ???

 

Advice is appreciated.

I have 9211-4i, 9211-8i (H200, H310) among HBA cards
All of them are changed to it-mode and used.

As I said, the HBA is stable in ds36xx, but in ds9xx, there seems to be a problem that the HBA still does not match the serial of the HDD.

Yesterday, there was an inquiry about the compatibility of the ASMEDIA chipset SATA card made by AliExpress at the server forum in Korea where I work.

So, as a result of checking the lspci-tvnnq log with the 6-port Marvel 4 port + ASM 2 port SATA card that I have separately, only the ASM chipset was not recognized.

I heard that there is a case where the chipset of the ASMEDIA SATA card has been confirmed, but I don't know exactly.

Satacard with more than 6 ports with only a complete Marvel chipset does not seem to be identified on Aliexpress.
And Chinese merchants falsely sell chipsets without telling them exactly how they are made.

I would start form this:

If you got only HDD drives you can use Dell Perc H310 and flash to IT, but if you have 8 SSD I would go with something which can handle:  HP H220 LSI 2308  (9205-8i) (PCIExpress 3.0) but depends if your motherboard supports it.

 

There are several factors that determine the right choice. 

-your current motherboard, does it support PCIE 2.0 or 3.0

  SAS2308 cards support PCIE 3.0 (HP220), SAS2008 cards support PCIE 2.0, these are the basic differences. 

-what case do you have, ventilation of case is very important because SAS controllers produce some heat

-what kind of disk do you want to connect HDDs or SSD. 

  

I use in my both systems Dell Perc H310 flashed to IT mode. Test NAS: DS3622xsp (Redpill) and working NAS: DS3617xs

I use SSDs and HDDs in the test DS3622xsp and in my working NAS 3617xs I only have SSDs and have never had any issues.

 

In my opinion is better to use SAS card and flash it to IT mode rather than external ahci sata controller. (if you are going to use them in DS3622xsp) I do not know what is support of above cards in DS918, DS920. I don't want to comment because I haven't tested them.

 

Please watch above and after that you can decide. 

 

Beware of counterfeits on Ebay.  - good to watch this as well: https://www.youtube.com/watch?v=mYHA77U7NyU

 

Good luck, do not be afraid of SAS ;)

In a forum related to server equipment in Korea, where I work, I showed a YouTube video to identify counterfeit products telling me to beware of the 3rd eBay, and I got the answer below.

I don't think there's any need to be suspicious of counterfeit products like that.

Rather, it is argued that the story of such a YouTuber is not 100% reliable.

Both are genuine in my opinion.

Since LSI is mainly OEM, even if it looks the same, it can be very different internally depending on where the OEM is.

To distinguish LSI cards, first classify them by chipset model rather than the card itself, and whether only the OEM model name has been changed from the LSI original card or the board is a unique design.
I think it's easier to differentiate them.

My opinion is a little different.

In that way, it is said that 99% of Intel NICs are fake, and there is a possibility that all cards received as OEMs from vendors are also fake.

I don't know if it's worth making a fake like that and selling it, but...

I wonder if it's worth making an entry-level card with no cash so sophisticated.

What I can expect is...

1. The revision has been changed.

2. The difference between OEMs.

3. There was a problem with the yield at the time of production of this product, so I received it through a supplier.

4. It was made differently according to the certification standard of the final supplier.

and so on.

The color of the board may be different when the revision is changed or there are multiple producers.

Most of the users of RAID cards are server vendors. It is extremely rare that these are manufactured for retail and sold to end customers.

If it was a problem to copy and sell IBM OEM products that are not retail products, IBM would not have known about this and would have filed a formal complaint with LSI.

It is strange that there was no such issue, and... if there are no major problems with the operation in common sense, it would be strange by itself.

The difference between the stickers on the back is that one is KC radio certification and the other is certification, but it is doubtful that there is a font difference. The location of the sticker has been changed, etc..

Some of the evidence that suggests that it is a fake product is that I think that it may well be the case with the genuine product.
