hi all...

a hosting facility build a new dedicated server for me and looking at the dmesg i see:

mfi0: <LSI MegaSAS 1078> port 0xec00-0xecff mem 0xfc480000-0xfc4bffff,0xfc440000-0xfc47ffff irq 16 at device 0.0 on pci1
mfi0: Megaraid SAS driver Ver 2.00

for df i get:
Filesystem       Size    Used   Avail Capacity  Mounted on
/dev/mfid0s1a    496M    197M    259M    43%    /
devfs            1.0K    1.0K      0B   100%    /dev
/dev/mfid0s1e    496M     12K    456M     0%    /tmp
/dev/mfid0s1f    661G    636M    608G     0%    /usr
/dev/mfid0s1d    8.7G    1.4M    8.0G     0%    /var


i asked for raid1. i cant find too much information about the mfi driver. just that it works with freebsd 7.

i'll keep looking but - has anybody successfully deployed production servers using the LSI MegaSAS 1078 in RAID1 on a very busy web server?
is there any loss in performance using that hardware in RAID1?
any performance loss in RAID1 at all?


thanks...
