Need hints for building a 6TB RAID5 Linux-Server!?
Hi!
I’m planning to build my own server with about 6TB storage in a RAID5 array. Lately i’ve read a lot about those things to inform myself but there are some things most people don’t need but I am interested in.
Some facts first though:
– I plan to use Ubuntu-server with webmin
– Software-Raid for my 6TB storage
– Raid5 is OS-free –> Storage only
– OS is on seperate disk in "onboard" RAID 1
– Server should run some simple programs or scripts like IRC-Bot
– FreeNAS looks nice but can’t run normal programs like IRC-Bot etc (right?)
So now to my questions:
– Should i use hdds with 5400 rpm or normal ones? it’ll be 1 gbit network card only so i think 5400 is enough. And they need less power make less noise and last longer right?
– What hardware should i use? Starting with a big enough casing to processing power and power source i got no clue what a pc like that needs. Since i’d like to use software RAID I don’t want to spend money on RAID-Cards.
– Eventually i’ll run Xen on that thing. Nothing too fancy, just playing around a bit. What OS should i use? I know Ubuntu but i heard CentOS is good for servers like that.
That’s it for now!
Thanks a lot for reading and probably replying!
Also if you got another good idea i’d be glad to hear it!
Thank you so much!

i don’t exactly plan to use it as a webserver so the bottleneck is not exactly the internet upload but the internal 1 gbit network i have.

Your bottleneck will be your network upload speed to the internet. I doubt you will have enough bandwidth to make use of high performance drives or CPUs, so just about anything will probably work ok at first.
Most disk drives now are 7200 rpm – older drives were 5400, but lower capacity, that would make it hard to get 6TB storage with just older 5400 rpm drives. Most home computers will be limited to 6 SATA drives, maybe 8. You would be limited to a 4,5 or 6 drive Raid5 array (since you have Raid 1 for OS). So, to get 6TB Raid5 storage on a single home computer, you have to use 1.5TB drives (or thereabouts).
Using a second machine with FreeNAS may enable you to expand to a couple more drives…
