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...
