Hello all,
I bought a Dell PERC 6/i T774H raid card, but it did not come with a battery pack. Is it necessary in order to use the card in general, or more just a good idea to have one?

Thanks!

It doesn't have to have it, but because of risks, you'll have to override settings to make it use the card's cache. I also don't recommend any parity based raid like 5 or 6 without a battery as with a power failure or sudden shutdown the risk of parity data not getting written will be high. Parity raids without caching enabled will suffer huge write performance losses.

Is it possible to get things setup and installed while I try and source a battery pack, and then plug it in once it arrives and retain everything I already had setup?

Yes, and most cards the battery is even hot swappable. On some versions, write caching automatically enables itself in the presence of a battery, in other models, you go into the software and check some boxes to enable it after installing the battery.

In this document it appears the 6/i enables and disables caching in the presence of a battery. There is a force write back option without a battery, as the page explains.
