LSI RAID Controller - HBA Equivalency Mapping

    It is a well known practice that many vendors re-brand LSI RAID cards and host bus adapters (HBAs) using different firmware and re-sell them as their own. Oftentimes, re-branded cards are less expensive to acquire than their LSI counterparts making re-brands highly desirable.

    It is also well known that using the initiator-target (IT) firmware mode is a great way to give up the RAID features of the cards, treating the cards instead as simple HBAs in IT mode. In turn, this allows operating systems that handle parity calculations to directly access the drives, thereby reducing the rate of TLER dropouts from RAID arrays among other things.

    The purpose of this post is to help users identify those cards which are simple LSI re-brands. This guide will only look at 8 port models for the time being. Normally the 4 port variants have a "4" instead of an "8" in the model number such as the 9211-8i (8 port) versus the 9211-4i (4 port).

    Isn't the IBM ServerRAID M1015 equivalent to the LSI 9240-8i? The M1015 certainly LOOKS like the 9240, not the 9211:

    M1015:
    http://www.redbooks.ibm.com/abstracts/tips0740.html

    9240:
    http://www.lsi.com/storage_home/pro...as/entry_line/megaraid_sas_9240-8i/index.html

    9211:
    http://www.lsi.com/channel/products/hba/sas_sata_hbas/internal/lsisas92118i/index.html

    Of course, that brings up the question of the difference between the 9240 and the 9211. They both have a PowerPC 440 CPU @ 533 MHz. The 9240 has the "MegaRAID stack", while the 9211 has the "Fusion-MPT architecture". The 9240 has "RAID levels 0, 1, 5, 10, 50 and JBOD mode" while the 9211 has "RAID 0, 1, 1E, and 10". The 9240 supports 64 physical devices, the 9211 goes to 256.

    I think I read somewhere that the M1015 has somehow disabled RAID 5, but I cannot find the reference.

    Maybe you read that from me since I posted that bit of info in another forum, but regardless I have a few dozen of these cards already and have spent some time with them.

    Yes the IBM M1015 is most equivalent to LSI 9240 in terms of firmware, it runs the iMR stack actually (lite version of the MR stack found on 926x and 928x cards) and its based on SAS2008 platform. And I said mostly equivalent to LSI 9240 because its had a few features toggled off in firmware, like RAID5 ability which is present on the retail LSI 9240-8i part. IBM's idea was to upsell the RAID5 feature with a software unlock key, so naturally LSI made it difficult to circumvent that by mere firmware cross-flashing.

    Thus unfortunately it cannot be cross-flashed to become an LSI retail part and inherit that feature set, the way one can do with certain other OEM LSI parts. It also cannot be flashed with "IT" mode firmware like the 9211-8i, even though they're both based on the same SAS2008 platform.

    It can however be firmware upgraded with the files from LSI's website for the 9240-8i. Reason being the firmware ROM file is universal for all variations of the card - retail and rebadged/OEM versions - this based on analysis with a hex editor. The firmware rom file also can't (easily) be modified because there's a hash check to protect against changed bytes, otherwise it would be (easier) to hack an OEM card into having the featureset of the LSI retail version of the card.

    On the bright side, these cards have been selling for $75 and less on ebay, and their default behavior is to present unconfigured disks as JBOD to the host O/S, meaning even though its running a lite raid stack, it behaves like a JBOD HBA until configured otherwise. While its usually regarded as technically cleaner to run a JBOD card with IT (target mode) firmware to do away with the overhead of the raid stack, in benches I really don't see the raid stack presenting a slowdown on this card. Example 16 drives in soft-RAID0 in Windows benches pretty much the same as my retail LSI 9211-8i w/ IT firmware. Same goes for Bonnie++ results in Solaris Express 11.

    Could be. Thanks for posting about them, by the way. I just ordered some, they are just so tempting at $75/ea. Can get 3 of them for the price of a new 9211-8i!

    They were $99 when I checked ebay yesterday! You guys are buying up the supply.

    Just the US supply! ;)

    I saw one guy in Malaysia selling one for $49 plus $60 shipping! :eek:

    I just got one for $80 shipped from eBay. I can confirm that it can't be flashed with IT firmware by the usual method. The SAS2FLASH utility refuses to recognize it as an LSI adapter, even when using the -o switch and specifically targeting it using its PCI device address (-cpci switch, IIRC). Mine had "9240-8i" printed on it in one place, and, I think "9220-8i" on another label near the serial #.

    I haven't tried it yet with actual drives connected because FreeBSD doesn't support it yet AFAIK, but it's good to know it can be used as-is without IT firmware.

    A couple of things still concern me though. I've heard that some RAID firmware will a) possibly write metadata to what it thinks are unused parts of the drive, potentially corrupting GPT disks, and b) may still expect a JBOD drive to have TLER, and thus will still drop it from the system if there's a read error. Anyone know how the LSI firmware behaves in this situation?

    Oh, also, how do you flash the LSI MegaRAID firmware if SAS2FLASH doesn't work? I couldn't find any instructions in the firmware download.

    Great thread, thanks. Just bourght 2 of these cards for cheap. What I havn't been able to figure out if it is bootable, forgive the silly question.

    I replied on the article about the ServeRaid 10 BRi instead of using the forum so apologies for that.
    If I understand correctly, the IBM Serveraid BR10i firmware doesn’t allow you to use this card as a JBOD device?

    I did find firmware for the sas3081e-r but unsure if it also applies to the SAS3082E-R (1 digit can mean a lot in IT land :) )
    found here: http://www.lsi.com/storage_home/pro...pters/sas_hbas/internal/sas3081e-r/index.html
    To make things easier there are 2 firmware available for the sas3081e-r with almost the exact same name:
    3081ER_P19_Supports_SAS_1-5G_3G_6G_&_SATA_1-5G_3G_HDD
    and
    3081ER_P19_Supports_SAS_1-5G_3G_6G_&_SATA_3G_6G_HDD

    Any ideas on which firmware I should use to flash this card to be able to use it as a regular JBOD controller?

    I saw one error, your link for LSI SAS3082E-R points to a 9211-8i on amazon.

    I used the first file you listed (one with SATA 1.5/3.0G support) and it worked fine on my BR10i.

    This is just a guess, but the only thing I figure out about why they have two different firmwares is that maybe there's some kind of compatibility problem in this chipset with SATA 6.0Gbps devices. So if you want to connect a 6Gbps SATA drive, the second firmware must contain some kind of workaround. Furthermore, this hypothetical workaround must also disable compatibility with 1.5G devices, so you can either mix 1.5G and 3G SATA devices, or 3G and 6G devices on one controller, but not all three at once. Of course, any 6G device would still run at 3G or lower since I'm pretty sure the LSI 1068e doesn't do 6Gbps.

    I have an IBM x3550 M3 1U I'm trying to get to do pass through SAS so I can use Linux software RAID easily with it. It came with the M1015 card, but it doesn't seem to present the disks as JBOD for me - it won't boot from it, the install CD doesn't see it etc... The best I can do is configure individual RAID 0 disks. This is a pain as you probably imagine. I was going to try to RE-FLASH to IT firmware, but it sounds like that doesn't work... Any info how you got this to work JBOD? Or any IBM part number that will be an LSI or whoever HBA rather than RAID? Cause I can't seem to get IBM to quote me a non RAID card for the SAS disks...

    First thing I'd do is try flashing to the latest firmware, either from IBM's site or from LSI's site in the 9240-8i section - either one, they're identical. Older versions of the firmware didn't present unconfigured disks as JBOD, but newer firmware does.

    Just a data point: The Dell PERC H200 appears to be a SAS2008-based card similar to the IBM M1015.

    In this thread people are reporting they have it working with the mps driver from FreeBSD 9.0, which supports the SAS2008, I believe.

    I have three M1015 cards working well with linux (Archlinux, kernel 2.6.37) in pass-thru mode. As odditory says, you probably need to get the latest firmware. I flashed mine with the LSI 9240-8i firmware from Dec 2010.

    Did you have to install drivers or configure via the WebGUI - or just flash the card with the LSI firmware (and not some IT mode firmware, but just general firmware) and then they are JBOD? We have flashed with the december IBM firmware, but will try LSI firmware if that will work...

    Good point. I wonder if I should also include the PERC H700 and H800 controllers based on the LSI 2108 and with NV cache options. From what I have read they are similar to the LSI 9260-8i (PERC H700 since that has internal ports).

    Anyone have experience?
