But when we tried to place our order, our vendor (Penguin Computing) advised us: "we find LSI does not work well with 4GB of RAM. Our engineering find that LSI card could cause system crashes. One of our customer ... has found that Adaptec cards works well on PostGres SQL -- they're using it as a preforce server with xfs and post-gress." Any comments? Suggestions for other RAID controllers?
