odd that it wouldnt install as it did for me just now. Is your ports
tree up to date? I'm guessing not since the latest version reference in
ports is 1.01.40 and you found and got the 1.01.09 rpm/zip
try updating your ports to the latest tree (portsnap is my method of
choice but csup works fine too :) then try
cd /usr/ports/sysutils/linux-megacli && make install clean
Be sure to pay attention to the post-install message as it tells you
about whats needed in the way of kernel modules and sysctl variables as
well as what periodic config is available.
We do have a server at work using the LSI Logic / Symbios Logic MegaRAID
SAS 1078 which hosts 40 VPS's running quite happily in a RAID 1+0
config, each VPS running web/mail/ftp for a number between 1 and 100
websites, so they seem to perform well enough, this is a linux server
though.
If you've been sold a RAID1 array i'd imagine thats what you have
unless you have reason to believe otherwise. It will appear as a singe
block device (/dev/mfid0) to the operating system though as you have see.
