Hi,
I have built my new media server over the last couple of weeks, and while I have thrown every piece of hardware at it that I was able to afford, I am not very satisfied with its performance - when I copy DVDs to this server, write performance still seems very slow. I would appreciate your thoughts on my build and what you would suggest that I should do to improve my write speeds.
HW:
- MB: Supermicro MBD-X9SCM-F-O
- CPU: Intel Xeon E3-1220
- RAM: 32 GB
- Host adapters: 2x LSI Logic LSI00194 Host Bus Adapter
- 1x system drive: Western Digital RE4 WD1003FBYX (connected to MB)
- 8x data drives: SEAGATE Constellation ES 7200 2TB SAS (connected to 1st host adapter)
- 2x logfile SSDs: Intel SSDSA2CW080G310 320 Series SATA (connected to 2nd host adapter)
- 1x cache SSD: Samsung MZ-5PA064/EU 64GB (connected to 2nd host adapter)
SW:
- VMware ESXi 5.1
- Nexentastor 3.1 as VM (with 20GB RAM)
- WHS2011 as VM (wit 8 GB RAM), connected to the Nexentastor storage pool through iSCSI
In Nexentastor, I have configured a raidz2 pool consisting of two volumes (4x 2TB drives each) and using the Intel SSDs for the logfile (mirrored) and the Samsung SSD as a cache device.
I had started this setup without the logfile SSDs, lower RAM (16GB) and without the cache SSD. However, upgrading with this (costly) hardware hasn't really improved my performance.
To be honest, I haven't accurately measured my write performance (I'm not really sure how to do that). So it's really just my "impression" how long it takes to copy a DVD rip from a client PC to the media server over the (1.000MB) network connection.
So I would really welcome any suggestions how to improve my performance.
Cheers,
teq
