Yes, if you stick (say) a 1.5TB, 1TB, and .5TB drive together in a

Isn't the PERC 6/e just a re-branded LSI? LSI added SSD support recently.
Yes, but the LSI support of SSDs is on later controllers.
Please cite your source for that statement.

What's a cylinder? That's a meaningless term these days. You dd byte ranges.
Pick whatever byte range you want. If you want mythical cylinders, fetch the

There's also been talk of two tools, MegaCli and lsiutil, which are
both binary only and exist for both Linux and Solaris, and I think are

lsiutil works with LSI chips that use the Fusion-MPT interface (SCSI,

There's a comprehensive test suite, and it apparently passes.
It's not exactly FUD. If you search the list archives, you'll find
