I have been working on the open-e test version for about 2 weeks now and I am unable to get better write performance than 20 MBs using a vmmachine running iometer using a 64KB Sequential Write. Reading using the same values is ok running around 100MBs.

There is no other traffic on the switch and the ESX Servers are also empty all tuning options seem to have no affect on the write values. Even configuring the underlying drives for raid0 has very little improvement. The underlying Hardware is a tyan 2882 dual cpu board with both cpu’s 8G ram and 2 3Ware 9550sxu-9lp controllers and 16 drives all enterprise sata drives from WD and Segate.

Is this really all the performance I can expect from the system or is something just wrong with my setup?

Thanks for your input.
