 Sequential I/O Performance of GPFS on HS20 blades and IBM System Storage DS4800
| | |
| This paper documents a study to demonstrate the sequential I/O capability of General Parallel File System (GPFS) for Linux on HS20 blades inside the IBM BladeCenter® blade server with the System Storage™ DS4800 storage subsystem using a 4 Gbps Fibre Channel interconnect. It details the GPFS file system configuration used to achieve maximum sequential I/O for both file read and file create performance, as well as the SAN configuration. It also discusses different GPFS parameters and their effects on sequential I/O performance. |
