NFS VM datastore is used for testing as the host running the FreeNAS VM has the NFS datastore store mounted on itself.Using PCI passthrough, snapshots on FreeNAS VM are disabled (this is fine).VMXNET3 NIC is used on VMs to achieve 10Gb networking.It is also still working amazing since upgrading FreeNAS to TrueNAS core. There has been no issues with stability in the months I’ve had this solution deployed. The NVME are provided by VMware ESXi as PCI passthrough devices. Make sure you check it out after reading this post!Īs mentioned above, FreeNAS is virtualizatized on one of the HPE D元60 Proliant servers and has 8 CPUs and 32GB of RAM.
FREENAS INTERMAPPER UPDATE
Update (May 1st, 2021): Since this blog post was created, I have since used what was learned in my new NVMe Storage Server Project. 10Gb networking between D元60 Servers and network.1 x FreeNAS instance running as VM with PCI passthrough to NVMe.1 x IOCREST IO-PEX40152 PCIe to Quad NVMe.Deploying SSD and NVMe with FreeNAS or TrueNASįor reference, the environment I deployed FreeNAS with NVMe SSD consists of: You should measure your network throughput to establish the baseline of your network bottleneck. You may wish to skip these optimizations should your network be the limiting factor, which will allow you to utilize these features with no performance or minimal performance degradation to the final client.
Some feature you may be giving up may actually help extend the life or endurance of your SSD such as compression and deduplication, as they reduce the number of writes performed on each of your vdevs (drives). These optimizations may in fact be wasted if you reach the network speed bottleneck.
With this in mind, to optimize your ZFS SSD and/or NVMe pool, you may be trading off features and functionality to max out your drives. It’s important to note that while your SSD and/or NVMe ZFS pool technically could reach insane speeds, you will probably always be limited by the network access speeds.
