Man spends $5,000 on a 48TB Raspberry Pi storage server • The Register

YouTuber tech whizz Jeff Geerling has discovered it's potential to spend $5,000 on a Raspberry Pi construct.

He did this silliness as a result of he is a self-described "artistic one that builds nice software program" with a sponsorship from Lambda Labs that retains him from redirecting his personal paycheck to quirky tasks.

He is additionally undoubtedly producing some revenue from Amazon referral hyperlinks all through his post and hawking wares from his merch store, however you recognize, capitalism. Cannot blame the man for seizing a chance.

Anyway, about that machine – Geerling began with this Taco gizmo from Radxa, which is an entire NAS/router answer constructed on the Raspberry Pi Compute Module 4.

He then turned every little thing as much as 11, including as a lot SSD storage as he might afford to his Taco to "see what it might do." Because it turned out, "what it might do" was 5 Samsung 870 QVO 8TB SSDs and one Sabrent Rocket Q NVMe SSD. The end result was a NAS packing 48TB uncooked storage, albeit at sluggish speeds in comparison with a contemporary desktop.

However total, the machine's efficiency was ... largely disappointing.

Regardless of having the ability to load it up with as many SATA III drives as one might need and select a good SATA controller, the factor was restricted in bandwidth.

"All RAID ranges (together with RAIDZ1) mainly maxed out the Pi's bus on sequential reads," mentioned Geerling, who added that the Sabrent NVMe drive was bottlenecked, solely seeing "just a few hundred megabytes per second of throughput in the very best case."

However the place the machine actually fell aside was when a rise in community visitors collided with the CPU bottlenecking.

"I feel the best setup for a Pi-based storage machine can be low-end SSDs (and even 3.5" HDDs – they work with the Taco too, although you have to SATA/energy extension cables), and RAID 1 or RAID 10 (or ZFS stripe+mirror). That means the Pi's CPU can be free in terms of placing by means of extra community visitors," mused Geerling.

He reckons the Frankenserver is completely sufficient over gigabit networks, much less so for quicker ones.

A board-only Taco must be accessible on the market for beneath $100 by the tip of 2021. A full equipment with the board, a pleasant steel case, and a Raspberry Pi Compute Module 4 can be accessible early subsequent yr for $200.

Does he advocate doing this at house? Properly, no, he doesn't. And The Register does not both except you even have a sponsorship. There is a motive issues come off the shelf as of late.
