upgrade for HP server

Yeah, for $100, maybe. Sucks when 512MB of RAM is worth, like what, $10 tops? If that. $2 maybe?
Exactly. I wonder why most of these seem to be limited to 1 or 2 GB of cache - 8 GB stick today costs what? $50? less?

Partially because it is NVRAM, so a lot more expensive to make than VolRAM. It's a different type of RAM because you can't have it losing state if the power fails.

Then what purpose does the battery serve?

There is no battery on modern RAID cards. I think our last battery on HP was around G5. Our G7 definitely is batteryless.

Well, this is a DL380p Gen8 and it has a battery - I can take a picture after my phone issue is solved if you like.

Maybe they still offer an entry level card. that would imply that you can't upgrade it because it isn't the same card as the 1GB one.

OH I am pretty sure I can't upgrade the current card - I'd have to simply replace it. It's a plug in card that goes into a slot that looks very similar to a RAM slot.

This one looks like it might work, but it still has a battery connector even though it's flash based.

"flash backed" means it'll store the contents of it's ram to flash when it goes to battery power, or am I missing something again?

Well that would make sense, but then Scott's early comment about NVRAM vs VolRAM wouldn't be correct, I wouldn't think - would they have three different options?
