+ | ===== Description ===== | ||
+ | |||
+ | The BINFL (short for Bioinformatics large) storage system was procured in late 2016 consisting of 192 x Seagate ST8000NM0075 8 TB disks. It shares it's metadata SSDs with the [[binfs|BINFS]]-Filesystem. Running 8 metadata servers (buddy-mirrored) and 16 OSTs. The nodes are used as storage and compute nodes, therefore they are connected via Intel Omnipath. Each Node also has a Mellanox Infiniband Adapter to connect the Nodes to the rest of the VSC-3. | ||

+ | |||
+ | The peak performance was achieved with [[tools: | ||

+ | ==== Sustained metadata performance ==== | ||
+ | |||
+ | The metadata performance was measured with mdtest, running 128 processes distributed over 8 nodes. | ||
