Achieve 2.0 GB/s + I/O Speed With ZFS On Proxmox For Your Dedibox Limited 1215 Server

Can't say I've tested this extensively or know much about it in regards to reliability or accuracy of the results.. but I was so amazed at the dd test from just choosing ZFS in RAID 0 from the Proxmox install that I thought I would post it here..

Just a word of caution.. this is only for testing and probably has no real value in a live server environment and that playing around with RAID or Choosing the wrong RAID type may lead to drastic data loss.. So please!! only try this on a test server.

Specs:



Dedibox Limited 1215

• 
  

  Intel Xeon E3 1220 V2 @ 3.10 Ghz

  
  


• 
  

  16 GB RAM

  
  


• 
  

  2 x 450GB SAS 15K

  
  


• 
  

  HP Smart Array P410 Controller 256MB Cache with BBU

  
  

Procedure:



Well not much to do.. my settings are as follows:

• 
  

  In my online.net console my Hardware RAID is set to RAID 0

  
  


• 
  

  Proceed to do a bare-metal Install of Proxmox from iLO choosing ZFS RAID 0 as file type as oppose to the default ext3. You can choose this setting under the options button in the Proxmox installer.

  
  

Note:



In RAID 0 with ext3 I would usually achieve a dd of 230/MB/s to 290/MB/s

Sample Results:



ZFS RAID 0
