LSI CacheCade Pro 2.0 512GB limit

[newjohnny]

You are right, only the data currently in the cache will be lost. Read-only caches are exempt from these two downsides.

I'm currently running cachecade on two controllers in raid0+1, so four 240GB drives per controller (almost 512GB). Moving to 2TB would require 16 drives per controller, but in raid5 this would only require 10 drives. There would be just one parity drive per volume, but I'm ok with that because of the global hot spares in place.

The new limit is now 2 tb for controllers with 2gb cache.

Hi. New to this. I have a LSI 9271-8i which is limited to 512GB with 1gb ram. How do i increase it to 2gb ram to capitalise on the 2TB caching ssd drive?

Thanks for any help in advance.

You cannot. You're stuck with 1GB.

You cannot. You're stuck with 1GB.

Then what controller would I use to get 2gb ddr cache?

The following raid controllers have 2GB or more ram:
9361-8i 2G
9460
9560
9580
