This needs to be posted somewhere, since it doesn't seem to be documented anywhere.
The NFS performance on the Black Armor NAS is just plain pathetic, laughable, and disgraceful. They should have just left it out, if it was going to be this pathetic.
Need a portable NAS that supports NFS to connect to VMWare ESX environments to copy templates between non-connected networks.
Hooked the NAS up to the network via gigabit and mounted the drive via NFS to the ESXi host.
Cloned a template and monitored its progress. Took 30 minutes to copy 1 gigabyte worth of data.
Accessed the NAS via CIFS/SMB on a Windows machine and copied a 1.41 gigabyte file and it copied in less than 2 minutes.
Updated the firmware, same thing.
Configured the NAS and the ESXi host to work while connected directly to each other, so there were no switches in between. Same pathetic performance.
So as far as I can see, the software inside these Black Armor NAS boxes cannot properly handle NFS.
Seagate Tech Support offered to replace the drive, but I've only had it a week and am going to send it back to NewEgg for the WD MyBook World Edition.
I will be leaving a review of this product on NewEgg's site, also.
All in all. What gives Seagate? Why would you release a product with a feature that's completely flawed and useless at those speeds?
Anyone else feel like commenting?

We are also using the NAS-110 with ESX 4.0 and its speed is very poor. It is also taking half an hour to copy 1 GB. It seems that it is some configuration issue of NFS in NAS-110. I have also tried NFS setup on Win2K3 but its speed is quite OK.
Anyone has any suggestions regarding how to improve speed of NFS access from ESX server.
