Hi everyone. First of all thanks for taking your time to read this post.
I am working on a build for a hybrid system using ZFS. The chassis has 24 3.5” bays for hdds and the will be 2 cards connected to two x8 slots containing up to 8 NVMe devices. We haven’t the cards yet.
The planed hdds are devided into 3 diferent pools.
Pool1 one is raid-z2 with 8 drives of 1TB each. It stores less frequently changed data.
Pool 2 is for home folders of both Linux and Windows Machines. It will also host an instance of TimeMachine. The plan is using RaidZ2 to improve reliability at the expense of performance.
Pool3 is for databases and we haven’t bought the hdds yet. There is a chance that they might end on the nvme and the extra 8 drives be used as a backup volume. This would mean transferring the TimeMachine to this pool.
NVMe pools are planed to use block storage or (;inclusive) database storage.
Hardware: Dual xeon e5-2643 v2 with 128GB of ecc ram evenly spreaded between CPUs. The CPUs are 3.5Ghz Xeons with 6 cores and 12 threads which seem to work well with pools with compression set to gzip-9.
Dual 10Gbit cards for San.
The motherboard is a SuperMicro X9DRD family with 6x PCIe x8 slots And an embedded hba in IT Mode with 8 links. The is also a card with a second hba from SuperMicro with 8 links.
To fill the entire chassis we might have to use an expander or buy another HBA. We aren’t sure yet . We have an intel expander but so far we haven’t tested if it works with the onboard hba connected with 8 links. We have had problems in the past with 8 link setups on expanders.
My question is simple but wide. Do you think this system is viable? Would you propose changes?
Thank you in advance for your help.
Best Regards,
MAN
