SAS2008 - LSI 9211-I8

From reading
LSI RAID Controller and HBA Complete Listing Plus OEM Models
Sas2008 LSI 9211-i8 is the only option for LSI MegaRAID and SAS (HBA)?

My mission is to have raid and hba option aio card on a decent price used on eBay.

Is the sas2008 only option?

Both the 2008 and 3008 are able to do basic RAID with the IR (integrated raid) firmware. This will handle RAID 0, 1 and 10.

What about hba? I need both hba/raid aio card like the LSI 9211-i8. But read that IR Mode is garbage and for one, sas2008 has no cache.

 

[vanfawx]

9211 can still pass through drives in IR mode. And cache is more of an issue for parity raid. IR mode works fine if you're using it for RAID1, at least it has for me.

What are you using this for?

 

[HITTI2]

Planning 4 3TB HGST's in raid 1+0 and 4 misc. hdd's on the last four SATA III ports.

Also would u know if 1TB would be detected on this LSI 9211-i8?

 

[vanfawx]

1) RAID 1+0 should be fine on IR firmware.
2) Yes, 9211-8i supports drives greater than 2TB

Hardware raid will most likely out perform LSI's IR firmware, but it might be good enough for your purposes, otherwise you'll need to look at more expensive options for hardware RAID which most likely won't support HBA functionality. If you want both in a single card, you're going to have to compromise.

Others might have some suggestions on HBA/RAID cards.

 

[HITTI2]

So when u say greater than 2TB, my 1TB will be non existent?

 

[HITTI2]

So much money for crap hardware...

 

[vanfawx]

When I say "greater than 2TB" I mean that all drives will work, including ones under 2TB.

 

[HITTI2]

Ah cool. Ty.

I'm new at this as u can see.

For my situation, four 3TB in raid 1+0 with 4 misc hdd's on this card, should I use IR or IT mode?

 

[vanfawx]

You will have to use IR mode if you want to use 4x4TB in RAID 1+0.

[HITTI2]

Yea boi. I put a 2" x 2" fan on the hs too.

For modern hard drives, the supported capacity boundary is around 2.15TB.

You only need to consider compatibility problem if it exceeds 2.2TB.
