And then I get IT mode? And then it works fine with Solaris 11 Express and OpenIndiana?

A question, does this m1015 support staggered spinup?
I dont understand how it works. How do I activate it?Yes.

I have 8 hard disks powered by one single molex. Yes, one single molex. When I boot the system, the disks stutter for a while, I dont know why - but suspect it can be because of power overload. I have heard that staggered spinup startsup one disk at a time? But... I have one single molex which is not connected to the m1015 - this means the m1015 does not startup the disks one by one? Or?
Exactly what is staggered startup and how do use it? Connect all disks molex to m1015 so it can start them one at a time?
I just ordered one IBM M1015 because of this thread. Very cheap indeed. However, it seems there are two different models?? I ordered the cheap one. What is the difference, and should I order the expensive one instead?
I ordered the cheap one
IBM ServeRAID M1015 SAS/SATA Controller (46M0831) (90Y4556)
The expensive one (30USD more)
IBM ServeRAID M1015 SAS SATACtrl (46M0831)
They seem almost identical. Have I done a mistake? Is this thread about the expensive one?
The cheap one says it can drive 16 disks, and the expensive one can drive 32 disks - is this true? I mean, there are only two SFF8087 ports which means they can only drive 8 disks. And, if I connect it to a SAS expander, then I can drive 255 disks, right? Far more than 16 or 32 disks. I dont get it. Should I cancel my order?
UPDATE: there seem to be several different M1015 models. Which one to choose? What are the differences? Am I smoked if I choose the wrong one?
Okay just to make this clear:
Option 1: No Flash
- Works fine with OpenIndiana, Solaris
- Works fine with JBOD drives
- Requires installation of 9240 driver from LSI website
- May have had a problem with some ESXi installations but now this is fixed? (Confirmation?)
Option 2: Flash to IT mode
- Works fine with OpenIndiana, Solaris, ESXi
- No extra driver installation required. Drivers are built in to OI, Solaris.
- Possibly better likelihood of working with more OS kernels out-of-the-box
- Flash procedure is here: http://lime-technology.com/forum/ind...4393#msg124393
So either way requires some extra steps. Really it's your choice of whether you think it's more trouble to install the driver or do the flash procedure.

Great summary. Your link is broken. I've seen a number of people point to that particular post, however, the OP of that thread updated the fourth post in the thread with a complete download which contains all the files needed. He even wrote some batch files to simplify the whole thing for those of us who are less experienced/lazy.

I used those files to flash my M1015 (BTW, thanks odditory.)
The expensive one has the RAID key? Gahh... How many models are there, and which models can I buy? Which is the newest etc etc? Are there big differences? Anyone knows more?
Molex switch is home made. The molex power cable is cut in two, and then a power switch is put in the middle. And on the molex cable, I have connected other molex cables split in three. And on them, I have connected other molex cables, etc - until I have 8 molex cables powering 8 disks emanatin from this single Molex cable.

2 links on that page. I'm guessing the file that you used was: LSI MegaRAID to SAS2008(P10).zip and not the first one?
But flashing the M1015 to IT-Mode using the 9211 (vs. the standard 9240) firmware disables HDD-spindown and other things, doesn't it?
So keeping with the iR instead of iT is generally recommended/preferred on the M1015...?

In fact, ZFS demands direct drive-access without any abstraction/raid-alteration in between, that's it.IT mode tends to be better supported
I never got spin down to work with the IBM firmware either. Has anyone else gotten spindown to work with any of the firmwares?

Since the M1015 and other state-of-the-art Controllers won't interfere at all in passthrough mode and additionally there is no measurable difference in benchmarks, it is totally fine to keep the M1015 in IR mode.
My Gigabyte motherboard and IBM M1015 does not work, they are not compatible. There is no solution than to change motherboard.
Windows displays error message, something about "not enough memory" or something similar. If you get this error code, then you should swap mobo. I can get into the cards' bios fine, but I can not start Windows.
