Yes the PERC5/i will allow you to create a 2nd RAID 10, you could also create a RAID 5 or a different RAID level if you wanted. [URL]~file=/storage/raid/perc5/en/ug/html/chapterb.htm#wp1056871
I have PE2900 that is running as our email server.  It is currently configured with 4 160gb SATA drives as a single RAID 10 virtual disk.  I'm running out of free disk space so I was wondering if the PERC 5i would allow me to create another virtual disk simliar to the existing one if I added 4 more similar disks?  Is this possible?
PERC 5i question: can I create two RAID 10 volumes?
