Hello List,

I'm evaluating current stable release of XCP1 on Fiber Channel Storage of Hitachi with 4Gb cache AMS2100.
I'm using boniee++ to evaluate the 2TB lun from a Centos VM 2 vCPU / 4GB RAM ( file size 8GB ). The VM runs on a Dell R410.

I'm getting a good speed of 120Mbps at times over 4Gbps FC.
My questions are
1) Is it really good speed over a 4Gbps FC ?
2) I start getting rport failure error if I repeat the tests for 3-4 times so is it normal ?
3) To solve above question xenserver forums are asking to upgrade the qlogic drivers, so are there any ?
4) There is no scli command in XCP1 version but as I remember there was "scli" command in XCP0.5, so is there a way to get back it ?
5) If I want to limit the storage access speed of VM what can I do ?

Thanks for help.

Regards,
Rushi
