NAS Build using an HP DL380 G5
« on: May 16, 2014, 06:43:30 pm »
I hoping to put together a NAS to use as a backup pool, and tRAID Flexraid seems a good option.  It will be for backup only, and will only be 4tb to start, but grow to 8tb over 3 years.  I have a HP DL380 G5 in great condition with 8x 2.5 drives bays I don't want to throw out, it has a P400 SA controller, but I also have an unused p410 from another box, both with BBW cache.

Here are my proposed HD arraignments for your criticism and input.  the P400 is 1.5gbs on SATA but 3.0gbs on SAS.

OS /Landing Drive: 
1x 300gb 2.5 SAS

Parity Drives: 
2X 1tb @7200 either HGST Travelstar  or Seagate Constellation 2 (which are still pricey). 1.2tb SAS are out of my budget.

Data:
4x 1tb WD Red @5400  or ?

w/ placeholders for 6 more drives.

The question I can't find is how many drives can one parity drive support, being of equal size?

I've only heard bad things about WD Red.

And as an answer to the last question: Unlimited. The thing to keep in mind is that more drives equals higher risk of single failure and if you only have one PPU and a DRU fails you have to be reasonably certain no other drive will fail while you do the restore because that would break the raid.
