a lot storage space (not a Promise Storage Appliance)



So today it continues. After the dissappointing things that happened around the Promise VTrak m500i we started to put the other machines together to do some testing. Therefore we have:


Machine 1:




  • Pentium 4 (Prescott) 3 Ghz


  • 2 Gigabyte of RAM


  • onboard Promise(!) FastTrack 597 SATA


  • 4 Port Onboard SATA


  • 2×80 Gigabyte (Western Digital)


  • 3×250 Gigabyte (Western Digital)


  • 1xGigabit Ethernet (Broadcom)


  • Windows Server 2003 Enterprise Edition


Test-Setup (Machine 2 is not in this picture…)



the drives and behind the fans…LOUD!

Machine 2:




  • Pentium 4 (Prescott) 3 Ghz


  • 2 Gigabyte of RAM


  • 2xPromise(!) FastTrack S150 TX4 SATA


  • 7×250 Gigabyte (Western Digital)


  • 1xGigabit Ethernet (Intel)


  • Linux 2.6.something


Machine 2 on top of Machine 1…



Machine 1 is destined to be the Documentation-Server running a Sharepoint Portal Server 2003. But we’ll do some testing with String Bean WinTarget 2.0 iSCSI Target Software. On Machine 2 the iSCSI Enterprise Target will provide access via iSCSI.



Our testing would be this: We setup a RAID5 on each machine and export this 500 Gigabyte Volume as an iSCSI Target Volume. We then benchmark this volume. After that we do this again with a RAID0 across the 3 drives. (so 750 Gigabyte Volume).


At the moment we only test with Windows on the client-side. We’re using h2benchw for this purpose.


Stay tuned for the results. Oh I almost forgot: The Promise VTrak m500i successfully synched a 1 Terabyte iSCSI Volume and I was able to mount and format this volume. The first test showed that about 66 Megabyte/s are possible on this RAID5 volume. The benchmark is running since about 2 hours – would take 6 more hours to complete. Of course we’ll also will test a stripe on the VTrak m500i.
