The State of ARM RISC in the DataCenter

The LeMaker Cello is a similar A1100 based board, available for 299 USD. Would be a perfect test / dev rig.

How close is that to being able to buy a micro-atx board chip and ram though...

Yeah, but that's an Intel system. The whole point about the ARM architecture in servers is Flops per Watt. They aren't as fast as Intel systems, but they are much more efficient.

Lets hope the pricing trend heads lower once significant production ramps up

Well, just from looking at the price of the dev board, which is considerable low, I would say we will see some interesting ARM based server boards in the future.
Also Linux and BSD both don't care much about the underlying architecture, which means that a proven OS is already available.

Sure, I get that. But when Dell/HP puts their spin on it, it will probably be nearly the same cost as typical servers. I'm guessing we'll only see a few hundred dollars cost difference on average.
Like others things, in this case the CPU probably isn't where most of the costs come from.

Think of larger scales. While a single A11xx probably can't beat a modern Xeon in anything but CPU power/watt, a whole bunch of them can. They could be pretty perfect webservers, in-memory database nodes, maybe even virtualization hosts for ARM based VMs at some point in time.

Sure, I see when we don't have typical 2-4 socket computers, instead a server might have 20+ sockets.
-
@thwr @Dashrender It will be interesting to see how it works out between consolidation (ARM server racks) and IoT/shards/stand-alone/single-board-computers

Actually the move will be to single sockets, at least at first. ARMs rarely support multiple sockets.

SBCs are the expectation for racks of ARM servers, like MoonShot.

So how do you see these appearing in the DC? Single socket, I'm guessing you're not virtualizing.

This makes great sense when looking at DevOps, but I don't understand how they would work in a typical virtualized setup - but maybe that's not who they are going up against?

Why? It can go both ways, but Xen and containers are the standards that are expected. Why would single socket not have you virtualizing?

DevOps and typical virtualization overlap. These are smaller individual units that you are used to, but why do you feel that this would significantly impact virtualization or deployment decisions outside of needing more nodes that are cheaper rather than fewer that are more expensive?

Don't forget that ARM SoCs can easily pack dozens of cores in a single package. For example: https://www.nextplatform.com/2016/09/01/details-emerge-chinas-64-core-arm-chip/
I would expect to see servers like the aforementioned MoonShot from HP: Lots of cores per SoC, but just one SoC per board. And dozens of boards per chassis.

Exactly. Blade approach, but very dense. So maybe 16 servers in a chassis. Each server might be 64 cores. So a 3U user might be really dense in cores.

Mostly because of the added overhead of a hypervisor for every processor. If you look at modern server today, has two sockets and 8+ cores. So that's like having 16+ processors.
I know ARM chips can have multiple cores, so I'm not sure where the problem is running multisocket is compared to multicore. But I did infer (probably wrongly) that a single ARM would be single core, and now you're talking about 16x the overhead for 16 versions of XS running to support all of those processors.Also, How do you give a single process more power over, for lack of a better term, separate machines?
I'm talking completely out of my ass because I don't understand the architecture of ARM systems compared to Intel.
