A brief about of FreeNAS 11.1-U4
[Enterprise-Grade Features, Open Source,
BSD Licensed]
Basic Requirements
- 64-bit hardware is required for current FreeNAS
releases. Intel processors are strongly recommended.
- 8 GB of RAM is required, with more recommended.
- FreeNAS 9.2.1.9 was the last release that supported
32-bit hardware and UFS filesystems.
- SSDs, SATADOMs, or USB sticks can be used for boot
devices. SSDs are recommended.
- 8 GB of RAM is the absolute minimum requirement. 1
GB per terabyte of storage is a standard starting point for calculating
additional RAM needs, although actual needs vary. ECC RAM is strongly
recommended.
- Directly-connected storage disks are necessary for
FreeNAS to provide fault tolerance. Hardware RAID cards are not
recommended because they prevent this direct access and reduce
reliability. For best results, see FreeBSD Hardware Compatibility List for
supported HBA disk controllers. LSI/Avago/Broadcom HBAs are the best
choice with FreeNAS.
- NAS-specific hard drives like WD Red are
recommended.
- Intel or Chelsio 1 GbE or 10 GbE Ethernet cards are recommended.
