Hi,
You have these guys as well, http://www.seagate.com/gb/en/products/enterprise-servers-storage/nearline-storage/kinetic-hdd/
I talked to them during WHD, and they said that it's not fit for ceph if you pack 70 of them in one chassi because of the noise level. I would assume that 1U wirh alot of sound and vibration canceling could cut it though.
They use a the sas interface as an ethernet port,pretty nifty.
Funny story, the first idea to this was 15 years ago, and they said they needed at least 16MB ram on the chip to make it work. Right :-)

Causing ceph to crash- if you put steady i/o and/or Cpu load for 15 - 20 min . the hardware will just pause.Downside were:Hi ,Question is what do you want to use it for . As an OSD it wont cut it.Maybe as an iscsi target and YMMVI played around with an OEM product from Taiwan ... I dont remember the name.They had an Armada XP arm soc and a SATA port + 2 ethernet. Pretty niffty.
- 1GB RAM .
- OS was using a custom ubuntu
- Ceph had to be compiled and deployed.hthOn Fri, Apr 10, 2015 at 10:04 AM, Philip Williams <phil@xxxxxxxxx> wrote:James Hughes talked about these at MSST last year, and some of his colleagues demonstrated the hardware: <http://storageconference.us/2014/Presentations/Hughes.pdf>
For tinkering purposes there is java based simulator: <https://developers.seagate.com/display/KV/Kinetic+Open+Storage+Documentation+Wiki>
The drives do use a key/value interface.
