Sun Storage 7110 Performance
As promised, I did a little testing. The following results are for Windows Server 2003 x64 running under XenServer 5.0 Update 3. The VM was given 2GB RAM and 2 virtual CPUs.
The 7110 is connected to the XenServer hosts as shown in the image - bonded gigabit copper links via a HP Procurve 2610G-24 switch. The XenServer hosts are told to talk to the storage on a special subnet which is VLANed off from the network too. Other VMs were running during the testing.
I used IOMeter with settings taken from recommendations at Operating Systems and Benchmarks - Part 5 (I have attached the config file too).
The full results are enclosed within the attached archive. A summary follows:
* 72.92 average IOps
* 0.81 average MBps
* 16ms average response time
* 162.42 average IOps
* 1.72 average MBps
* 7.71ms average response time
I also incluse a comparison with my workstation (a HP xw6200 with a SATA hard disk) to show some context:
* 107.34 IOps
* 1.18 MBps
* 9.31ms response time
These are very basic, simulated tests but do suggest NFS to be the quicker connection type under these circumstances.
I intend to run a longer test when time permits to give a better idea of speed. I will also add a comparison between file transfer rates straight to the Sun Storage 7110 via CIFs and to the storage via a VM running Server 2003.
