Hello

First of all, thanks for your answer.

Past day, we had a meeting with Clarion engineers, customer and us.

Clarion engineers admitted to have set up a bad configuration of LUNS.

It seems there is problem of missalignment, in case of Windows. Is necessary to do a format manually to Labels of Windows, using Diskpart

By default whenMicrosoft Disk Manager formats Clarion LUNs it creates a partition starting at 63rd sector,which misaligns the partition with the underlying storage subsystem.This can cause a greater I/O load than is necessary.

If anybody wants more information, ask me.

Thanks and regards

Javier
