The benchmarks were performed on a Unison appliance featuring two 8-core Intel Xeon E5-2687W CPUs, 48 direct-attached 3TB 7.2K drives, and 12 direct-attached 120GB SATA SSDs. Inktank's Ceph Enterprise file system was presented as a single mount point and the databases were in a single directory, rather than splitting the database across many mount points, as is common practice for this benchmark. These attributes are unique to a distributed file system model and create opportunities to explore work flows with more than one client.
"Working with Inktank allowed us to produce a very high performance flexible storage system that is extremely reliable", stated Dr. Joseph Landman, CEO of Scalable Informatics. "When testing a read-dominated workload using Kx kdb+, Ceph outperformed running on native block devices, demonstrating its low overhead, I/O optimization, and scalability."
Unison is one of Scalable Informatics' Fast Path Big Data appliances. It supports Object, Block, and File storage and eliminates data silos and storage complexity with a solution built specifically for multi-tenancy and Cloud. The appliance provides feature-rich, dense, scale out storage for private Clouds and large-scale virtual machine infrastructures.
"On the heels of STAC benchmarking results that place Ceph as the fastest parallel file system, Inktank is pleased to be fostering a partnership with Scalable", stated Ross Turk, Inktank's VP of Community. "When Ceph is coupled with Scalable's hardware, it delivers the type of storage system today's enterprises need."
