The only PCIe Gen4 link in the system is x4 between the CPU and the X570 chipset.īut since this Server should be limited performance-wise by the Intel XL710 with 2 x 40 GbE anyway I think I’m now pretty happy with the mentioned configuration and stop tinkering with that as of yet experimental system.īut that ZFS Server has nothing to do with the Windows system I wanted to directly use ZFS RAIDZ2 on mentioned in the first posting here.

Distros may provide out-of-tree drivers (usually some kind of dkms version) from their repositories but they’re far from being production-ready. The configuration seems to work fine but stability testing is a pain in the ass due to shitty SFF-864 cables, but I’ve given up on PCIe Gen4 here since the Delock 90504 is PCIe Gen3-only (but I initially wanted to have a configuration that could handle PCIe Gen4 without having to replace the two used quite pricy Icy Dock MB699VP-B V 1 for MB699VP-B V2 ) Answer (1 of 5): Linux actually has zero native support for ZFS due to licensing reasons. OpenZFS is a CDDL licensed open-source storage platform that encompasses the functionality of traditional filesystems and volume manager.It includes protection against data corruption, support for high storage capacities, efficient data compression, snapshots and copy-on-write clones, continuous integrity checking and automatic repair, encryption, remote replication with ZFS send and receive.

2 x Intel Optane 905P 480 GB, 1 x via CPU M.2, 1 x via X570 U.2.

its derivatives, macOS, ZFS on Linux via kernel module, Microsoft Windows.

Intel XL710 QDA2 gets its 8 PCIe Gen3 lanes from the X570 chipset OpenZFS is a CDDL licensed open-source storage platform that encompasses the functionality.

Broadcom HBA 9400 8i8e gets the other 8 CPU PCIe lanes (8 internal SATA SSDs, 2 external SAS 3 expanders for up to 2 x 24 SAS/SATA.

When that tunable is 0, ZFS will consider only free space, so the the expense of the best-fit allocator can be avoided by keeping free space above 5.

8 x U.2 NVMe hot-swappable in two backplanes (PCIe Gen3) (drives connected via Delock 90504 PCIe Gen3 x16 AIC with Broadcom PEX8749 PCIe switch, the PCIe switch gets 8 PCIe lanes from the CPU The recommendation is 10 rather than 5 because metaslabs selection considers both location and free space unless the global metaslablbaweightingenabled tunable is set to 0.

Back to practical considerations… how’s windows iSCSI performance? Can you use a pair of 40G nics and mount a zvol?Ĭurrently I’m still building my dedicated 2 x 40 GbE ZFS Server:
