Poor FC performance in comparing with competitor

[Al-S]

The Lite version has some limitation, as it does not support 10 Gb Ethernet, or Multiple CPU Support, etc.. for more details about different between Free Lite version of DSS and the full DSSv6, please visit this link: http://www.open-e.com/products/open-e-dss/comparison/

Also you said you have 8x600GB HDD, that means you have 4800GB (4.8TB) ? as the Lite is only designed to deal with 2TB of storage. while the Full DSS can deal with unlimited size.
So please try with the full DSS version, also try to tune your system, to match the same as other products, and please try to test both, as all can claim, right!

We installed trial version of DSS 6.0 and get additional information concerning IOMeter options from AVRORAID. They got test using file pattern with block size 1 Mb (100%). We used the same pattern and repeat test. The result is better, but still is worse than AVRORAID 280 MB/s. Specialists from AVRORAID believe, that Open-E can't work properly (with high performance) with large block size (1MB).

It is not surprising for a vendor to try to dismiss another vendor's products.

One thing to consider... does the AvroRAID product support the same feature set as Open-e? Volume Snapshots?

Don't get me wrong, I think that AvroRAID has some potential (I had a look for myself, too bad they don't have a North American base/var network). I just want to make sure that you realize what the trade-offs (every solution has them) are between the 2 solutions.
