Subject: Best option for SSD caching on a md raid array?
Date: Sun, 07 Feb 2016 22:14:08 -0700	[thread overview]
Message-ID: <1670804.QnHtKWfib8@nell> (raw)

Hi,

I'm planning on setting up a dual raid5 array for hosting vm's off LVM, I would 
like to add an ssd cache to help with typical server system loads, and some 
mixed read/write loads for game servers.

I'm wondering what the "best" route for me to go is. There's a few options 
that I know of, like flashcache, dm-cache, and bcache. The question is which of 
those is better suited to my use case?

Also wondering which ones people here use, and what they use it for.

Thanks!
