We have recently setup a NAS with 80 TB of space, with maximum capacity of 200 TB on easily available Off-the-shelf hardware.
Hardware we used:
1. Xeon Quadcore processor
2. Intel motherboard
3. 8GB DDR3 RAM
4. 4U 36bay hot swap chasis with redundant power supply and Expander Backplane & Rail Kit.
5. LSI SAS 4port Raid controller
6. 120 GB SSD drive for OS.
7. WD NAS disks(4 TB).
Detail off Our Setup:-
A. We used 120 GB SSD hard disk for OS.
B. In intial phase we have setup 24 disk of 4TB each with total capacity 24 x 4 (TB) = 96TB.
We have setup two hardware Raid 5 volumes with 11 Disk each and two global hotspare disks.
Each raid volume has around ~40 TB of space, hence 80TB in total currently.
C. We left the 12 chasis bays unused for future expansion.
D. Now the best part:- 1. The LSI raid card can support 6TB drives.
So in future we plan to replace 4TB disks with 6TB disks or we still have the bandwidth to expand 12 x 6 TB= 72 TB due to 12 unused bays.
Reason for using 4TB disks is that 4TB disks are comparatively cost effecting compared to 6TB disks.
E. If we used all 36 Disks of 6TB than we could achive total capacity of 36 x 6TB = 216 TB.
F. LSI Raid card we have has support of maximum of 128 disk of 6TB. Just imagine 128 x 6 TB = 768 TB at one place.
G. No vendor lock-in for any hardware and software, no license fees and free software, no limited hardware support for only three years. Every component like motherboard, raid card, chasis back panel etc. is replacable and easily available in the market.
I. The whole setup was so seamless and smooth, and server was ready for deployment within two days. Previously we had setup OMV for 10 TB NAS, two years ago.
Our heartful thanks to the
a. OMV developers(specially Mr. Volker) for creating such a product.
b. Our Hardware vendor Mr. Amit Kalra (email ID:- amit@buycomps.com, website:- http://www.exlsystems.com/).
