Ceph - Linux on the controller...

[kemic]

This looks pretty interesting:
504 OSD Ceph cluster on converged microserver ethernet drives

1 node per disk... Literally.

@Jim thank you for sharing. That is awesome.

ok... not what i imagined(I was picturing a standard ethernet port) but very cool hopefully this helps bring down storage costs overall

This is a very active area of development. WD and Seagate are pushing competing standards for the pinout and interface on the SATA connector, though there is some evidence they are pushing towards a single converged approach.

There are at least a dozen companies I am aware of working different versions of this same idea, including the usual drive manufacturers (WD, Seagate, HGST), the big equipment dealers (HP, Dell, etc) and a whole pile of ambitious startups.

Publicly:

SM already has a chassis based on Seagate's "kinetic drive" stardard: Supermicro | Products | SuperServers | 1U | K1048-RT with Part List. 12 drives and an Ethernet switch in a 1U chassis.

Also see here for a startup doing all SSD drives with a rather generic Linux on them (with Ceph OSD "application" all packaged up):

Interesting point on the Olive specsheet is that they're using eMMC. I wonder what impact that'll have on performance.

Probably not enough to hamper a gigabit link, this is a benchmark against a 32gb eMMC module from a intel compute stick, sequentially it could saturate gigabit Read Sequential no problem, assuming they have some level of added parallelism moving to a higher capacity Sequential write should catch up fairly quickly

Note that the interface standard proposals - both the WD and Seagate versions - anticipate support for 2.5gbit.

I still think with internal parallelism they could saturate it.

wow i need to keep up with technology this shit is cool.
