10th International dCache Workshop

11 Apr 2016, 09:00 → 12 Apr 2016, 18:00 Europe/Berlin

11.13 (UAB - CASA CONVALESCÈNCIA)

The 10th International dCache workshop is an event in a series of workshops, meant to build and maintain an active dCache community and to strengthen the relationship between dCache system administrators and dCache developers.

During the dCache workshop you will learn about the most recent developments, future plans, which are very exciting as dCache is becoming a QoS enabled storage solution.There will be a session concerned with Zookeeper and much more well worth a trip to Barcelona. You will hear all about that during the workshop, very exciting times. As always, we are working very hard on the logistics and the agenda.

This year's workshop is organised by dCache.org.

8 Exploring the Efficiencies of Operating dCache in a Virtual Environment On a Mass Storage System

Large dCache installations generally employ a server running both dCache and a file system attached to an external storage device which is connected through a bus allowing SCSI transfers. For redundant storage the external device is often a RAID controller with a block level interface and a common connection is Infiniband. In that case the server uses a Host Channel Adaptor on a PCIe bus and the transfers are SRP (SCSI Remote DMA Protocol). This solution is highly scalable but each data transfer is burdened with the protocol latency associated with an external bus. An architecture will be discussed which runs both dCache and the related file system in a virtual environment on the RAID controller rather than on an external server. The result is that the normal external bus protocol latencies are eliminated and the memory space of the file system and the RAID are co-located. A SCSI transfer is reduced to a simple data pointer operation. Iterative data transfers are accomplished with far greater efficiency and fewer memory copies. Data transfer rates from a production system will be presented along with the reduced space and power requirements for this implementation.
