I'm new to this CacheVault add-on. Been reviewing some youtube marketing fluff but still confused. Can they be connected to most LSI cards or only a select few? Will it attach to their 24 port card? Does it just plug in where the BBU normally goes?

Looking at LSI's website, the 9271-8iCC looks like a card I might consider. I'd want to start with plugging in 16-24 SATA devices. Loosely, how would you get there? Multiple cards?

Expander to add extra ports ?
Case with expander built in.
Multiple controllers, ie 3x to get 24 SAS/SATA ports.

9271-8iCC (CC= CacheCade)
But it does have the optional CacheVault module, which you'll need to purchase also.

Multiple cards will cost an extreme amount of money if you add the CacheVault option to each. And you cannot create arrays with drives on different controllers. Combining SATA drives with SAS expanders may not be the optimal solution, but it works in most cases. If you don't mind that a newer model exists you can also buy the 9260CV-8i which includes CacheVault.

Isn't the 9271-8iCC newer tech than the 9260CV-8i? I thought it was when I compared the overall specs of both.

I guess I'm also confused by how some of the storage builds out there are getting big volumes when most of LSI's offerings are 8 ports.

LSI9260CV = SAS2108 = single Core ROC, PCIe 2.0
LSI9271CC (with Cachevault option extra) = SAS2208 = Dual Core ROC PCIe 3.0

You could get the IBM M5016 = Cachevault as standard = SAS2208 but PCIe 2.0
Then get an expander
BUT the M5016 doesnt' support Cachecade/Fastpath etc

LSI9260CV are quite expensive

Yip as they are on the controller and any drives attached to the controller will get the benefit even via the expander.
I've not tested this, so don't hold me to it, but it's supposed to work.

I'm not seeing an expander on LSI's website, just chips. I do see a Areca ARC-8026-NN on tekram.com though. Would these be good expanders to use with the LSI cards and SATA disks?

LSI supply OEMs with the expander chipset

IBM, HP make the cards, Supermicro include them with some cases.
Do your homework with expanders as not all are born equal

Can CacheVault and CacheCade be used at the same time ? It worked on 9260, but I have some issues with 9361... anything changed on that field ?

I found interesting article on Lenovo about CC SSD compatibility list.

CacheVault = BBU for onbord controller cache
CacheCade = Cache tiering using ssds, requires software or hadrware license

I would be surprised if you can't use both at the same time.
