    Hi

    Long story, but try and keep it short.

    On our Supermicro servers, SAS drive light up solid blue, but SATA drives do not (they only light on drive access) - this is the behaviour hard coded by Supermicro.

    As we are using more and more Samsung 850 SSD (SATA) devices, this is becoming an issue, with one exception - a couple of test Kingston V300 SSD's light up as if they were recognised as SAS drives.

    Does anyone know if there is a change we can make to Samsung SSD's to duplicate this?

    Hope the above makes sense

    Thanks

    NNN

    It must be by design as Intel & Chembro backplanes do the same thing.

    Supermicro are looking into making changes, but not sure if I will be able to update existing backplanes.

    Strange how the Kingston v300's we use for testing light up like a SAS drive, yet other SSD's\SATA drives do not - hence wondering if something can be turned on in the firmware?
