Lustre Capacity

Sizing Lustre For Throughput and/or Capacity

Applications will dictate the throughput and capacity of a HPC storage solution using Lustre.  Lustre is a flexible file system that allows for scaling capacity horizontally or vertically to meet the application I/O requirements.  Scaling capacity horizontally, or scaling-out, will increase storage throughput and capacity by incorporating additional Object Storage Servers (OSS – processor, memory, and I/O) attached to dedicated storage enclosures.  Scaling capacity vertically, or scaling-up, will increase storage capacity behind fewer Object Storage Servers.  Below is a diagram that illustr
