About GPFS-WAN:
GPFS-WAN (Global Parallel File System-Wide Area Network) is a 613-TB storage system. The system is physically located at SDSC and is mounted on Trestles. GPFS-WAN is recommended for long- or short-term data storage of high-volume multi-site runs, as well as for large XSEDE-based data collections. GPFS-WAN has three partitions, each with its own policy regarding access, allocation, and data preservation: 1) a Long term collections area; 2) a Projects Area; and 3) Scratch Area (for short term data analysis).
System Configuration
GPFS-WAN consists of p575 nodes with 16 GB of memory per node. Each node is divided into two Logical Paritions (LPARs) for a total of 32 NSD servers. There is a total of 2GB/s of bandwidth from each NSD server. The total capacity of GPFS-WAN is ~613 TB (RAID 6). All the nodes are directly and redundantly connected to the storage.
