Hello,
I want to repurpose some hardware which exists out of 4 HP P2000 enclosures with 12 x 3TB disks each and 1 HP Proliant DL380 G7 as FreeNAS host.
The purpose of this setup is to temporary store data before it moves to the backup system. IOPS are not important, redundancy and capacity are.
There will be no deduplication or any drives for caching, just the disks in the enclosure.
The specifications:
- HP P2000 with dual sas controller (non raid)
- 12 x 3TB in each enclosure
- Dual Intel Xeon E5620
- 48GB ECC DDR3
- 2 x dualport SAS HBA (LSI 9200-8e)
As IOPS are not important i want to use VDEVS of 12 disks each and raidz2.
Also the enclosures are connected such that multipath can be used over 2 HBA's.
Questions i have:
- As the dataset spans all 4 enclosures, all the data will be gone when 1 enclosure fails.
- I currently have 1 vdev per enclosure. Would it be better to span 1 vdev over all 4 enclosures for additional redundancy/performance ? I think not...
Please share your opinion.
