Hi guys,
i came here because i have been looking for backup enterprise solutions and also tried truenas in lab which comes much cheaper with use of high end DC stuff than enterprise solution offers.
What i have tried:
R710 - 2x 6c @3GHz
90G ddr3 ecc rdimm
LSI-9405w trimode
8x8TB raid z1
1x 2tb nvme p4500 for slog
2x960G s4510 for dedup .. (i had some spare so i needed to try to eliminate slow parts of spinners )
10G network.
With dataset i have copied about one third of datas from main repository (synology 10x10TB and 2x960G ssd 0 ) and i have reached dedup ratio about 2~3.
Due to 10G network and secondary lab storage i could not pass to more than 700MB/s of write. (DD zero to file on disk went about 1.2GB/s -> i believe limitation of slog drive)
What i need to build (REQUIREMENTS) :
Reqs 2-3GB/s stabil troughput of writes.
Daily is written about 2-4T of new datas.
500TB of deduplicated and compressed datas in final. (Now i have about 120TB storage and buying another ) Backup is with one month retention.
4x nvme 4TB drives with 3dwpd idk if samsung or intel.
special volume for instant recovery VM 10TB would satisfy. (veeam it will mount as datastore and you can run VM from there and do live vmotion to main cluster storage)
budget is about 20-30k usd.
I was thinking about :
supermicro 847BE1C4-R1K23LPB 36x sata/sas with optional nvme
1x AMD EPYC™ Rome 7542 - 32 Core - 64 Threads - 2.9GHz - Boost 3.4GHz - 225W - 128MB Cache
256GB of ram
26x10TB wd sas drives HC510 or smth like that in raid z3 (for sure 3 drives can die, i can manage new in about 1 week and change instantly as it arrives )
i think broadcom (lsi) hbas 9400 or 9500 series.
4x nvme 3-4TB drives like intel p1725b or intel p4610. (for sure 2x in mirror for slog)
The main question is ... what performance to expect? Will it handle my reqs? What would you look after ? What would you change to have more reliability / perf stability ? How to tweak zfs for large files ? (one veeam backup is like 50G and incremental 5-10G, and hundreds of VMs)
I dont trust yet truenas for production environment so backup is really my first try. I have built two labs (one mentioned) so i want to give it a shot.
Thanks for help and sorry for my broken english :)
