So, I'm working on building my NAS. Currently I have a quad core atom (I think? Bought it a year ago) with 4GBs of DDR3, and 5 750GB SATA hard drives (don't remember if SATA II or SATA III). Looking at buying a 1TB for parity. I'm probably going to go with Ubuntu 14.04 LTS running snapRAID The case has room 9 drives total internall, and I can always add more via esata or something. Looking for other suggestions, critique, discussions, etc, keeping in mind that I'm not made of money (so, yes I COULD go with 9 4TB drives... but then I couldn't pay my bills) I'm thinking I'll probably start with 1 TB parity drive, then add a second parity drive later for redundancy.
after a little research, since RAID is NOT backup (as any good sysadmin will tell you!), it looks like I can get unlimited backup for my NAS for ~$5 a month through Crashplan, and that it's possible to, unofficially, install the service on the server headless and connect using the client from another computer. That will give me, to start, 3.75 GBs of data, not counting parity, that is both redundant locally, and backed up externally. https://www.code42.com/store/#/ I'm not a fan of using Java (though I was assured they are working on a native client), but there really is no other good options that offer both unlimited backup AND work on linux AND aren't ridiculous prices ($100 a month for bitcasa)
Oooo already filled disks, AND disks of different sizes? What is this witchcraft! I'm going to have to check this out. sent through the air using science
Yes, it looks real neat! Only caveat I've read about so far is that the parity disks MUST be as large or larger than your biggest data disk.
does anyone have any experience with SSD Caching in linux? looks like I might be able to improve some performance by adding an SSD (looks like I can get a 32 or 64GB SSD for less than $50) for caching read/write requests to increase I/O?
so, got my NAS sucessfully built this weekend: CPU: AMD A6-3650 APU with Radeon(tm) HD Graphics RAM: 4GBs of DDR3 HDDS: 1 80GB SATAII, 1 1TB SATAIII, 4 750GB SATAIII Services: SnapRAID, mhddfs, samba, nfs, smartmontools Total Storage: 3TBs (I only had 4 750GB drivers, not 5 like I thought but adding more is easy )
