I'm looking for input on my first FreeNAS build. I've got experience with traditional RAID, but this is my first time on ZFS.
Usage
Rationale
Questions
Usage
- Location: Home
- Primary Use: Media storage (i.e. Data at rest. More reads than writes)
- 1-5 users
- Secondary use: 2-5 VMs
- 1 user
- Goals: Maximize storage, reasonable rebuild time in event of drive failure.
- 2x Xeon 2680v3
- 128 gigs RAM
- 10 gb copper LAN
- Clients are limited to 1 gb
- Internet bandwidth is limited to 300 mb
- Case that can handle 36 hotswap drives
- Separate UPS
- OS Install
- SATA DOM
- ZFS Pool 1 (For bulk storage)
- VDev 1 - RAIDZ2
- 5x 14 TB Drives
- VDev 2 - RAIDZ2
- 5x 14 TB Drives
- VDev 1 - RAIDZ2
- ZFS Pool 2 (For VMs)
- VDev 1 - MIRROR
- 2x SATA SSDs (Probably 1 TB each)
- VDev 1 - MIRROR
- In case of drive failure and rebuild, each VDev in Pool1 is isolated, reducing the time needed to re-silver.
- Two drive redundancy in data is sufficient for my home media usage. Each VDev is 42TB (14 x 3) unformatted storage.
- Adding another VDev to Pool 1 for future growth will be easy.
- No dedicated SLOG. I anticipate it to be unnecessary given my light workload, but can add it on later.
- 128 GB RAM seems sufficient given light workload, but the mobo has plenty of room to expand if necessary.
Questions
- Is more drives per VDev appropriate? What's the general tolerance towards number of drives in RAIDZ2, and balancing resilver time against desire to minimize space "wasted" (invested?) on redundancy?
- Do folks agree that an SLOG is likely unnecessary in this build?
