Re: [Openstack] Volume driver in Cinder by ISCSI way
Hi Harry, If you have questions about EMC volume driver, you can email me.

You can see their driver files here: https://github.com/openstack/cinder/tree/master/cinder/volume/drivers If i wanna discuss questions about their ISCSI driver ways, i should go to which mailing lists or ask anybody? it seems they are all not open source projects, which belong to companies. -- Thanks Harry Wei ___ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp ___ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp

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.

Re: [Openstack] Volume driver in Cinder by ISCSI way
Harry, EMC's volume driver (implemented in emc.py) is open source but EMC storage is not. EMC volume driver allows users to provision EMC storage in OpenStack. This is the same case with many other vendor provided drivers. The EMC volume driver that is available currently supports iSCSI protocol on VNX and VMAX/VMAXe arrays. I have a README for how to use this driver in Folsom. See the following link: https://github.com/xing-yang/emc-openstack-cinder We are still doing development for Grizzly, so I don't have a README yet. You can take a look of the Folsom doc to get started. Let me know if you have any questions. To add another driver, you can just add it under cinder/volume/drivers like emc.py.

Our project web is: http://code.google.com/p/cloudxy/ HLFS's doc is: http://code.google.com/p/cloudxy/wiki/HlfsDesign . And we will first realize Openstack support driver by QEMU/Libvirt way like Sheepdog. Then we will also realize Openstack support driver by iSCSI. At that time, if i happen to some questions, i will suerly ask you, would you? ;-) Do you understand sheepdog's driver by QEMU/Libvirt in details? If i add a QEMU/Libvirt driver to let Openstack support HLFS, I should change following stuffs, right? 1, add driver file to the dir (the same as sheepdog), https://github.com/openstack/cinder/blob/master/cinder/volume/drivers 2, change the file (Let libvirt attach HLFS volumes to QEMU, the same as sheepdog)， https://github.com/openstack/nova/blob/master/nova/virt/libvirt/driver.py Do you have any other suggestions? -- Thanks Harry Wei ___ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
