I'm looking at picking up an Intel RS25SB008 (a.k.a. OEM LSI 9286CV-8e). I am wanting to add CacheCade to it, which I see is done via the AXXRPFKSSD2 feature key. My question's are:
Thank you in advance for any answers!
My apologies for not being clear... let me restate my question. I looked for any RAID specific groups on the community and didn't find any. If I were to move this to another group, which one should I move it to?
Intel RAID controllers are part of the server products group.
For your questions:
• Will the resulting version be CacheCade Pro 2.0? I don't know that there ever was a CacheCade 1.0 version available on this board, but I want to make sure that's not what I'm getting.
Intel's version is Intel® RAID SSD Cache 2.0. Intel® RAID SSD Cache 2.0 uses LSI MegaRAID CacheCade Pro* 2.0 read and write caching technology.
• These has been quite a bit of chatter about a newer version of CacheCade coming (some suspecting 2.1 or 3.0) that, most significant to me, would raid the size of the CacheCade virtual drive to something larger the current limit of 512GB (1 or 2TB in the rumor mill). Given that I have nothing solid to work from here, I am not asking for "commitments" but would welcome well-educated guesses as to whether or not Intel will have a new key once this is available?
Unfortunately we can't make forward looking statements.
• The above wouldn't matter if you could use the LSI branded CacheCade key with this board, but given my recent experience with an IBM OEM of the LSI 9260-8i (IBM M5014), I am betting it's going to be something unique and not cross-compatible.
We don't advise using LSI components (keys, firmware or software) with Intel branded RAID controllers. While Intel RAID controllers use LSI's MegaRAID technology there are changes done cross platform.
• While I realize the implications of doing so (voiding warranty, etc...) does any one have an experience with the RS25SB008 and trying to cross flash it to LSI firmwares?
See above. Yes you would void your warranty.
• Last, and this confuses me the most... if you look at the specs on this card in various places, you will see it
listed at PCI-e 3.0 and PCI-e 2.0. This intel page refers to it both ways on the same page! (Intel® RAID Controller RS25SB008) Very confusing...
At release the Intel® RAID Controller RS25SB008 was PCI Express* 2.0. A future engineering change is planned to upgrade the RS25SB008 to PCI Express* 3.0.
Thank you, John. That gets me a lot closer to understanding this. I did some more research based on your responses and came up with some things others might find relevant. I'm sure you (John) already knew them since you seem to be an Intel staffer :
Thanks for any assistance,
The PCIe 2.0 to 3.0 engineering change for the RS25SB008, RS25AB008, RS25NB008 and RS25DB080 controllers was cut in a year ago, see http://qdms.intel.com/dm/d.aspx/1E6F0BB2-36B7-4B00-9F48-1B44A47C3377/PCN111557-03.pdf PCN 111557 - 03. We'll get the user guides updated.
Awesome! Now we're making some progress! If we could just get to the bottom of this CacheCade versioning, I'd be all set.
The last question I guess I would have... I have seen the pages that list the combinations of hardware and raid controller for the Intel -> Intel combination. If purchased the retail version of the RS24SB008 along with the AXXRPFKSSD2 feature key, is the use of the card in a non-intel branded board supported at all? Meaning, would the first question I got from support always be "please give us the model of the system you have this installed in," and if the answer to that question was anything but what was on the supported list, I would be told they wouldn't look at the issue?
Intel wants to sell RAID controllers. We would support an Intel RAID controller in any system to the best of our ability. However our expertise, for obvious reasons, is with Intel products.
We do have 3rd party server boards that we have validated the RS25SB008 with. You can see that in the RAID controller http://www.intel.com/support/motherboards/server/rs25ab080/sb/CS-033039.htm Tested Hardware & Operating Systems List.
I would highly recommend checking the board you might plan to install an Intel RAID controller to see if it is validated as compatible by the board manufacturer.
Ok, last questions, and then I think I'm going to have to buy one of these babies!
"Stepping change to D1 of the ROC Controller to allow Gen 3 PCIe functionality"
Thank you very very much for all your great information!
Correct, the controller stepping and firmware update are required for Gen 3 PCIe functionality.
If your vendor gives you the old version, hopefully they don't have any left as the PCN was dated over a year ago, I'm pretty sure you could plead your case to Intel warranty and get one warrantied to the new version.
It would be much, much easier if you provided the required key part number to your vendor and your requirements for that specific version though. Just sayin'...
Thank you, john_s. You've answered everything I can think to ask! There are two sellers on eBay selling the controllers new for a great price, and I was looking at picking one up. But, I asked both of them which MM rev they were, and both were selling the old one. So... apparently they got a couple of lots of the leftovers and are clearing them out. Something just seems a little "wrong" with buying one of those, knowing that, and then calling support to get it swapped out...
Hopefully all this information will live on in the archives and someone will Google upon it and benefit from it!
In the previous message you indicated the 915316 to 919499 MM numbers which are for the AXXRPFKSSD2 Premium Feature Key. That's what I was talking about possibly working with warranty to get an update. The last email you indicate MM rev for "controllers". That to me is the RS25SB008. That may be a little harder to "upgrade" via warranty.
