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.
