Morning Everyone.
Been running my Freenas for the past 18 months solidly in a production environment. I want to switch out the system board and CPU for something that has a much lower idle power draw, and therefore way less heat. The problem is, I have all of my machine room in a 8'x4' space in a rack, cooled by a 15,000BTU AC unit, and it has trouble keeping up when we are pushing the systems.
What we have now:
Supermicro X8
Dual L5640
96GBRAM
Chenbro 48 Drive Case
Chelsio T520
Two LSI HBAs
Pool 1 7x6 RaidZ2 Vdevs 8TB (Vault and Backups. set to spin down after 60 minutes)
Supermicro SC847 45 Drive Enclosure
Pool2: 14x2 Mirror 4TB Drives (Main Production Pool, all large video files)
Pool3: 2x1TB SSD (Holds FCPx Libraries, tons of small files, holds system dataset)
Pool4: 3x4 RaidZ1 6TB (Additonal Production Pool, for less resource driven projects, all large video files)
Additionally in that room is all our networking gear, a Synology DS1815+, two Mac Pros(2009 and 2019), and 2 UPSs, plus some random hardware raids.
I know I won't be able to get rid of all the heat generated by the drives, but I am thinking since my Freenas box is mostly at idle, I could loose a lot of heat upgrading the system board and CPU. I originally had planned on getting a Xeon E5 v2 system but was able to score a good deal on a CPU/Board combo for a v3 System, so what I am thinking about replacing the system with is:
Xeon e5-1650 v3
SuperMicro X10SRL-F
From my understanding, this should reduce my idle power draw by a significant amount, between the chipset and CPUs. And I will be gaining in single core and multicore performances without losing any PCIe lanes. Performance wise I am already mostly maxing out 10GBe, so I am not really looking for more performance. My question is about RAM.
I currently have 96GB of RAM. Moving to a V3 CPU I obviously need to move to DDR4, but can I get by with 64GB of RAM? or should I spend the money and get 128GB. my ARC size hovers around 20GB, but I do see it spike up to 76GB at times. With mainly large video files, I don't feel like I see to much benefit from the ARC, but I do see a ARC Hit Ration above 90% most of the time. But for a cost difference of $100, I guess I should just go with the 128GB.
Thoughts?
