We are looking for Ceph subject matter expert. An individual that has performed install sizing, installs and configs as well as tunning at the ceph level.

The primary role will be to identify/ suggest lower-level configuration settings that may need modification to fit our SDS solution. In addition, this role will assist in the packaging of ceph as it relates to our deployment models. Low level C++ coding is not needed at this time. This would be more of a system developer working on integrating ceph with our solution; bash scripting and Python would be a perfect match.

The candidate must have a thorough understanding of:

Ceph components (Monitor, Ceph OSD / journal, OSD scrubbing, Ceph Manager etc.) and the various configuration settings.

Examples:

osd_max_write_size

osd_max_object_size

osd_client_message_size_cap

osd_max_scrubs

osd_scrub_load_threshold

osd_scrub_chunk_min

Bluestore and the various configuration settings

Examples:

osd_memory_target

osd_memory_base

bluestore_cache_size_ssd

Understand the differences between bluestore and filestor at a technical level.

Understand the resource (mem, cpu, throughput) impact when ceph is self-healing or expanding

Proven track record of Ceph deployments, including pre-deployment sizing, CPU and memory constrains.

Regards,

Parijat Banerjee
