LSI Logic MegaRAID SATA 150-4

[Oliver Lehmann]

Hi,

since my fileservers bootdisk died this night, I'm toying with the idea to
move over to a SATA-RAID setup. Are there any known problems with LSI Logic
MegaRAID SATA 150-4 and FreeBSD 6.0 around? Is it easy to attach a 4th disk
later and enlarge the 3disk RAID-5 setup I plan to start with? Is there a
FreeBSD tool around for managing the controler like mlxcontrol for Mylex
controlers? If not, can I manage it through it's BIOS interface or am I
stuck to MS-DOS or worse MS-Windows? Anything else I should know about this
controller before I'm gioing to buy it?

Greetings Oliver

nope, it works just fine, it's even listed in the amr manpage.

That's a controller issue primarily, although you will have to expand the
freebsd slice, which might require some magicks, or a backup/restore.

there is an open source monitoring tool ( not management ).
The card is fully bios manageble.

I'd purchase the 300-8x, which should have a substantially
faster onboard cpu. The 150-x is a bit of a dog compared to
other current sata raid options.

most of these questions arent freebsd specific, and quite offtopic
for current@ list ....
