Home Built NAS passes Hi-Resolution 4 Room test

Posted by: Aleg on 23 February 2010

Hi

I thought it might be usefull to share some results from the Naim NAS test tool:

I have a home built NAS running Ubuntu Server.
quote:
Specifications:
OS: Ubuntu Server 9.10 64-bit
Kernel: 2.6.31-19-server
Motherboard: Gigabyte GA-MA78GM-DS2H (F1 Firmware)
Processor: AMD Athlon(tm) Dual Core Processor 4850e
Memory: 2 GByte
Disks: 4 SATA-300 from Samsung EcoGreen and Western Digital Green
Volumes: 1 combined volume using LVM2 with LUKS Encryption
File System: Ext-4


The NAS test tool was run from a Windows Vista Premium 32-bit Desktop.

All network components are 1 Gbit/s components.

The NAS is Cat-5e cable connected to the same switch as is the desktop and the network router (DLink DIR-855).

It was tested using 4 Rooms, High Resolution for 5 minutes (other settings in default).
The circumstances were less then favourable because I had a large system download running using 40 % of my network bandwidth. But I thought if it passes now then it will certainly do in better circumstances.
The test results were:

One thing worth pointing out from previous qualifications–it is well-worth running the test for a 24-hour period, as this will catch any energy-management or time-related QoS glitches that might arise during the lengthened qualification testing process.
