Re: Online Labs – ARM servers in the cloud
#32I think the big use case for ARM in datacenters, over the next few years, is for servers whose CPU usage is very low today--they're consistently network-bound or they just act as a relatively dumb interface to RAM or disk (memcached, some distributed DBs, some dumb proxies). Baidu uses ARM for cloud storage, Facebook used AMD servers for memcached despite their lagging Intel on speed. Basically, you look elsewhere wh…
This Marvell SOC has 16 Serdes integrated inside the SOC can be partition to Gige ethernet, SATA, or PCIe in any numbers of ways.

Along with low power, make it very interesting.
I can see someone put 64, 128 of them in 1U chassis. This might be interesting low cost system for someone who need simulcast live video streams to millions of users at really low cost.
"64 4 cores CPU each with integrated 16 GIGE ports for fan out live video stream that potentially fit inside 1U chassis"

Nope, the cloud is about automation and self-service.
If the provider tells you what you're getting you can always ignore that information if you don't care. But some customers care about hardware specifics.

#34You can access the service preview, ask an invitation on twitter @online_en or on irc.online.net #onlinelabs
Re: Online Labs – ARM servers in the cloud
#35This is really cool. The price is obviously going to be a question. The other thing I wonder is if this is more or less reliable than a VPS, in case of hardware failure.
Re: Online Labs – ARM servers in the cloud
#36Not impressive at all. Performance is not different from RK3188. Disk speed is also not impressing. Not good example of ARM server.
I wonder what advantages this product have if any?

128 Armada cores in 1U is nearly impossible due to cooling issues.

May be not for Armada, but most of cell phone ARM cpu, the power is 1-2 watts at max frequency.
If that hold true, 128 SOC in 1U can be 2-300 Watts. That can true ly go against x86 for "some" applications.

Actually 3-5 for current gen. And you don't count all other things that are necessary for practical system: PCI-E connectors, RAM, Ethernet PHYs, etc.
P.S. I believe in 64 in 2U, though.

Yes if you're utilizing a service built in "the cloud". No if you're implementing said service.
