I challenge Linus to make that server (to scale or calculate) to consume no more than 1.45 Watts per TB of usable space, assuming RAID-6.
Rules:
Max. Total TDP 1450W per PB of usable space, RAID-6.
1 CPU core = 3 HDD
1 GiB RAM/TB of raw space
3 GB of SSD (SLC, eMLC or MLC) cache per TB of raw space
Has a speed of 1 GB/s write and 2 GB/s read.
Can Linus do it?
I doubt it.
But in my calculations,
it IS possible. (The efficient ones are below 1.4W/TB usable, but I can make below 1.1W/TB usable.)
Enjoy ur headache Linus.
