Abstract
Ceph based storage solutions are becoming increasingly popular within the HEP/NP community over the last few years. With the current status of Ceph project, both object storage and block storage (RBD) layers are production ready on a large scale, and the Ceph file system storage layer (CephFS) is rapidly getting to that state as well.This contribution contains a thorough review of various functionality, performance and stability tests performed with all three (object storage, block storage and file system) levels of Ceph by using the RACF computing resources in 2012-2014 on various hardware platforms and with different networking solutions (10/40 GbE and IPoIB/4X FDR Infiniband based). We also report the status of commissioning a large scale (1 PB of usable capacity, 4k HDDs behind the RAID arrays by design) Ceph based object storage system provided with Amazon S3 complaint RadosGW interfaces deployed in RACF, as well as performance results obtained while testing the RBD and CephFS storage layers of our Ceph clusters.
