Hopefully someone who knows more about this can confirm it's accurate. My understanding is that:
On its own, the 9361-8i has a 1GB DDRIII DRAM cache. If you get a power failure, you're going to lose the data in the cache. *If* you could attach a battery backup unit directly to the card, it...
The CVFM04 is the CacheVault flash module, a daughter card which attaches to the 9361-8i via a connector next to the heatsink. That's where the flash memory is. On the CVFM04, there's a socket to plug in the CVFM02, which is the CacheVault power module; correctly a supercapacitor pack, but...
The culprit was the used MegaRAID 9361-8i. I bought a new one and have been running it without CacheVault and BBU for a fortnight without any incident. A new CacheVault and BBU will go in this week, and hopefully that'll be it.
Unfortunately I'm not able to offer any recommendations as the storage connectivity drops didn't go away and I haven't managed to fix them. To update the thread:
MegaRAID firmware was updated to the (then) latest May build before I started.
Playing with the various cache and...
I replaced the MX100s with a pair of 1TB Samsung QVO SSDs and added another two 3TB WD Reds to the RAID 10 array. That was in addition to swapping to a MegaRAID 9361-8i and a new install of ESXi 7.0 booting from a USB stick.
Initially, things seemed fine, but there were clearly...
ASRock H97M Pro4 motherboard
IBM ServeRAID M5014 RAID card with LSI MegaRAID 9260-8i 12.15.0-0189 firmware and BBU
4 x 3TB WD Red hard drives in RAID 1+0
2 x 512GB Crucial MX100 SSDs in RAID 1

In anticipation of a clean install of ESXi 7, I've picked up another...
ASRock H97M Pro4 here, which retails for £60-65 in the UK. mATX, four DDR3 slots for up to 32GB, x16 PCI Express slot. I've had two M5014s running on this board (one in the x16, one in the x4), and the only problem's been accessing the WebBIOSs. This is only a problem if the attached drives are...
Kind of. It's only a problem with the latest Oct 21 release. All (and I checked about half of them, so it's a fair assumption) of the LSI firmwares up to this one allow renaming. I've settled for the last of these, 2.130.403-3066, which was released on May 9, 2014.

It negatively impacts boot up time, that's for sure. Adds at least an extra minute. From what I can see, earlier firmwares allow you to change the SBR, thus get a fast boot and an LSI branded card. Later ones seem to rename the card back to a ServeRAID, undoing any gains.
I've just picked up a pair of IBM ServeRAID M5014s and BBU08 batteries. The intent is to use one in the Asus P6TSE board on my workstation, and the other in the ASRock H97M Pro4 which I'm building an ESXi server around.
So, using the instructions on ServeTheHome, the files from LaptopVideo2Go...
