RAID5 Tests on Elonex PC using multiple write streams and files Nov 06

RAID5 Tests on Elonex PC for single stream sequential file access Nov 06:

  • RAID disk system Write: memory to Disk transfer rates as a function of file size for ext2, ext3 and xfs Linux file systems.
  • RAID disk system Read: Disk to memory transfer rates as a function of file size for ext2, ext3 and xfs Linux file systems.

 

Raid tests for SC2004 on Boston SuperMicro systems

  • 3Ware 8508 RAID tests
  • 3Ware 9000 RAID tests

Steve Dallison's plots of disk-memory (read) throughput vs data transfer size and memory-disk (write) throughput vs data transfer size for the ICP SATA controller with 4 disks and 3Ware SATA and Parallel controllers for RAID0 and RAID5 with operation on PCI busses running at 33 MHz and 66 MHz.

Throughput Tests on the BaBar DiskServer Jul 03

  • 3Ware RAID5 disk-memory for 3, 5, 7 & 8 Disks as a function of the max_readahead Linux virtual memory parameter.
  • UDP Network throughput Gigabit Ethernet mem-mem
  • PCI activity for read & write operations
  • bbcp disk-disk transfers.

 

Enjoy, but the usual disclaimers apply!

Feedback and bug-reports are welcome and I will do my best to fix things
