Studied Physics with main focus image processing in Heidelberg from 1990 until 1997, followed by a PhD in Edinburgh 's Heriot-Watt University in 2000. Worked as sysadmin during the studies, mainly in the Mathematical Institute in Heidelberg. Now working at SUSE Labs as Kernel Storage Architect and Teamlead for storage and networking. Principal contact point for storage related issues on SLES. Linux addict since the earliest days (0.95); various patches to get Linux up and running. Main points of interest are storage, (i)SCSI, FC/FCoE, and multipathing. Recently got involved with the NVMe-over-Fabrics effort, participating actively on specification and implementation. I'm active on the Linux NVMe and SCSI mailing list, reviewing patches and dusting out murky corners in the SCSI stack. And implementing odd features for NVMe-over-Fabrics.
