I bought a new HP Microserver N54L to use as a home media server, to back up our family computers' files (my Linux and wife's Windoze), and to back up 3 separate company files. It will be replacing a Netgear NAS which can't decode DVDs.
1. RAID: I am familiar with hardware RAID from my company servers. They require identical size HDs. I guess with mdadm software RAID, the HDs can be different sizes. This microserver comes with a 250GB drive. I was planning on adding two 2TB drives for data. I was planning on using RAID 1 for the data, but not for the OS. When I installed the OS on the server, I used LVM. I was not planning on using RAID for the OS, but in reading this forum, it seems I should have configured it with RAID first, then LVM. Comments? Suggestions?
2. Security: how should I handle security? Should I have separate VMs with separate IPs for the backups of the companies (we have a VPN so that would be simple) so that the data is segregated, or would it be better to just make separate "users"?
I don't (or do I?) want security for reading/serving the DVDs and music, but I don't want my grandchildren accessing the backups and other data.
3. Any other recommendations? I've been reading this:
Thanks for any and all help!
