Scalable Open Source Storage Architecture

In Mai I gave a talk on a scalable Open Source storage architecture at the HLRS event in Stuttgart (10th HLRS Workshop on Scalable Global Parallel File Systems) as a speaker of GRAUDATA. At the moment I am working on that integration. GRAUDATA plans to present a scalable archiving system at CeBit 2012. The goal is to combine the CEPH cluster filesystem which provides a POSIX interface wich the POSIXS VFS layer of OPENARCHIVE. The result will be a product for cloud or HPC environments which allows to handle nearly any amount of data in a very efficient and scalabale way.

Another interesting setup is the combination of CEPH with LIO. LIO is the default SCSI target in Linux since 2.6.38. LIO is abale to export a standard Linux block device via iSCSI, FC, FCoE and Infiniband. CEPH provides a RBD (RADOS block device) which can bes used as a backend for LIO. The result will be a redundant highly scalable SAN storage which can be uses in all datacenter environments as a replacement of existing proprietary SAN technologies. The intagration with all existing hypervisors is possible through standard protocols like iSCSI, FC or IB.

I uploaded the latest edition of a presetation on INFINISTORE(tm) to SlideShare. Get it here.
