Anybody running SETI on a switch?

[/url] "On the QFX5100-AA, Juniper upgraded the X86 processor to a four-core Xeon E3-1125C v2 (which is an “Ivy Bridge” generation embedded chip) running at 2.5 GHz, and found that Junos only needed a half core of processing to run atop its hypervisor. That left three cores of raw compute that it can expose through its hypervisor to run Linux applications right in the network stream. The QFX5100-AA has 32 GB of memory allocated to that Xeon E3 chip plus 128 GB of SSD storage, and importantly, has two 10 Gb/sec Ethernet ports with drivers that allow for kernel bypass, yielding very low latency from the network into the Xeon chip and back out again."

First, sorted your URL to make it work properly (You'd added a space that wasn't needed:
http://www.theplatform.net/2015/04/06/traders-bank-on-server-switch-hybrids-for-performance-boost/

I expect it would be about the same as any other Xenon running only three cores, and even then one might find it hobbled as so much of its performance potential is tied up with getting network traffic through as fast as possible.

Thanks for sorting out the link! :)

I think 3 cores are basically left free so some naughty IT-admin could rack up some points. Has it been done though and would anyone admit to it?!

Ni!

No, but I'm running it on a 15 TB disk server.

Only 15TB? Try 32TB!

Well, OK, it's only a Mac Pro connected to a NetApp SAN, but I have to beat you in something, right? :-)

Well, it's an old server (20 or so 1 TB drives) that I rescued when it was retired for being out of warranty -- it's our group data server/backup (still 13 TB free). I'm thinking of slotting 4x 8TB Helium drives in the spare bays of one of my 20-core servers if I can convince The Professor to find the dosh, our sysadmin wants to get some idea of their reliability before we switch to them in ~2 years' time (he tells me we'll have something like 1.5 PB in our data centre when the current tender is met and delivered).
