Equallogic and vmware benchmarking

Speed Benchmarking with read/write in MB/s

Equallogic Model Speed tests:

  • A vmware VM using SCSI LSI logic SAS was used
  • The Sequential read and write are based on a 4 GB file.
  • The resulting MB/s speeds are based on the average of 5 passes
  • CrystalDiskMark was used for disk benchmarking
  • All disks were formatted and blank at time of benchmarking
  • The PS6510 was connected via 10GE while the PS6000 and PS4000 were connected via 1GE

Equallogic SAN connection types in vmware tests:

  • The Sequential read and write are based on a 4 GB file.
  • The resulting MB/s speeds are based on the average of 5 passes
  • CrystalDiskMark was used for disk benchmarking
  • All disks were formatted and blank at time of benchmarking
  • All tests were run with 10GE connections on the same PS6510

Conclusion:

The upgrade from 1 to 10 gig ethernet made a big difference in the speed results for the Dell Equallogic model tests and helped remove a hard cap on disk speeds based on network limitations. Vmware connection types were all similar but setting the disk with a higher priority in the vmware settings improved write speeds by approx. 20MB/s. SCSI was the best connection solution not only for speed improvements but also for snapshot support in vmware and veeam.
