Re: [Openstack] [Swift] Cache pressure tuning

). That's roughly the performance you can get when your storage system gets into a 'steady' state (i.e. objects # has out grown memory size). This will give you idea of pretty much the worst case. Jonathan Lu On 2013/6/18 11:05, Huang Zhiteng wrote: On Tue, Jun 18, 2013 at 10:42 AM, Jonathan

Re: [Openstack] [Openstack-dev][Sheepdog]Add a new driver for Openstack Cinder like Sheepdog volumes

It seems you also have tgt patch for HLFS, personally I'd prefer iSCSI support over qEMU support since iSCSI is well supported by almost every hypervisor. On Jan 19, 2013 9:23 PM, harryxiyou harryxi...@gmail.com wrote: On Sat, Jan 19, 2013 at 7:00 PM, Huang Zhiteng winsto...@gmail.com wrote

Re: [Openstack] Volume driver in Cinder by ISCSI way

For development efforts, it is better to use openstack-dev list instead of this general openstack list. You can also join #openstack-cinder IRC channel in freenode for online discussion with cinder developers. On Jan 18, 2013 9:27 PM, harryxiyou harryxi...@gmail.com wrote: On Fri, Jan 18, 2013
