@uint8_t @th not "can saturate 10g"-fast bit pretty fast: my current nas works quite well and uses not a lot of power (i3-10105, connectx-3, sas2008 based hba, one nvme and one sata ssd in zfs mirror as bootdisk, a used sas ssd as zfs slog and two 12tb seagate exos disks. Uses 14W when running proxmox with a openwrt vm and hdds spun down and around 35W with the disks running and a samba file transfer).
Biggest power hog in HDD based systems are the HDDs... (And I'm too cheap for all-flash ^^')

@uint8_t for that sort of scale SSD + RAID6 is feasible, so you don't need to go fancy with the drive controllers. One caveat for 10Gbase-T is that the phy alone can consume multiple watts per port, so if you multi-home it you might be close to your power budget just from the network stack.

@uint8_t reading the other replies, I see you already figured that out and are planning on SFP+...

@th @uint8_t yeah I'd recommend fiber even for "at home" where possible just because 10g base-t is so power hungry ^^'

@jakob @uint8_t the hyperscalers really want silicon photonics since they forecast that almost all of the power consumption in future switches is just heating up the copper traces (current switches are already over 1/3)

@th yep I'm aware of how hot the 10GbE interfaces can get... planning to use the 1GbE until that is saturated and then power on the 10 GbE
the few seconds additional latency is not an issue
