Microsoft Service For UNIX (SFU)
This method can be combined with the Microsoft Active Directory method to allow
using the same user names on both NFS and CIFS. To translate CIFS user IDs into
NFS UIDs, Storwize V7000 Unified queries the Active Directory Server to retrieve
the NFS UID that is stored inside the Service for UNIX (SFU) extensions on the
server. The administrator maintains the NFS UIDs
Planning for power
Each enclosure is provided power through two power supplies. Either power
supply unit can power the enclosure independently if there is a loss of input
power to the other power supply in the enclosure.
Therefore, plan to connect the power cords of the power supplies on the left side
of the enclosures (when viewed from the rear) to one power source, and the power
cords of the power supplies on the right side of the enclosures to another power
source.
Attention: The power cord is the main power disconnect. Ensure that the socket
outlets are located near the equipment and are easily accessible.
The locations of power supply units in Storwize V7000 Gen2 enclosures are shown
in Figure 2 and Figure 3 on page 22. The locations of power supply units in
Storwize V7000 Gen1 enclosures are shown in Figure 4 on page 22 and Figure 5 on
page 23.
The power supply units in a control enclosure are not interchangeable with the
power supply units in an expansion enclosure.
Figure 2 shows the rear view of a Storwize V7000 Gen2 control enclosure with the
power supplies 2 at either end of the enclosure.
