Our Lustre file system currently comprises 6 HP DL380s with dual, dual core 2.66 GHz Intel Xeon processors and 8GB of RAM. Two servers are used for Lustre metadata and the remaining 4 are used for object storage, each equipped with dual, dual port Qlogic card and a Infiniband SDR card. Both metadata servers are directly attached to a HP SFS20 storage array (RAID 5). Two EMC CX-380 storage couplets front 144 TB usable SATA II disk and are attached to the OSSs via 4 Gb Fibre Channel (FC). Each of the OSS's Qlogic ports function as a primary path for three OSTs - 3TB LUNs. The problem that I am having is that regardless how we stripe our Lustre file systems, our aggregate performance is always somewhat the performance of a single OST - which is around 700MB/s.
Any help is greatly appreciated! Thanks, Anhvu Q.
