Hi All, This is my first post, I have been using Ceph OSD in OpenStack Icehouse as part of the Mirantis distribution with Fuel - this is my only experience with Ceph, so as you can imagine - it works, but I don't really understand all of the technical details, I am working for a college in Ireland and we are planning on deploying a larger private cloud this year using the Kilo release of OpenStack when it matures. I am architecting the physical components and storage has become quite complex - Currently we use a Dell Equallogic Array and we have configured the cinder service to use the driver provided by Dell, the nodes in the data centre don't have a lot of local storage. So here is my Ceph ignorance laid bare
1- I have enough compute nodes to run a ceph cluster, radosgw etc. as per http://ceph.com/docs/master/radosgw/ 2- I have no available local disks * - this is the problem 3- I have a Dell Equallogic SAN and fabric (7.5k NL SAS) 4- I have access to storage as a service from our ISP - this is an IBM storwise V7000- I can provision block storage and mount iscsi volumes, it's across town but we have a p2p layer 2 connection The use cases will be students on a Masters in data analytics using OpenStack Sahara and S3 for data sets. So if I mounted remote storage or network attached storage would it work? Can I put Ceph directly in front of my Equallogic array and use ceph for cinder, glance, nova and S3? Has anyone any thoughts or experience on this - thanks for taking the time to read this and any input would be greatly appreciated. All the best, Rob. ________________________________ The information contained and transmitted in this e-mail is confidential information, and is intended only for the named recipient to which it is addressed.
