Appendix A: FAQs
1. Q: What is the different of SW16 and SWF16?
A: SW16 is the pure PCIe 2.0 switch of ExaSAN switch series. SWF16 is a three-in-one
PCIe 2.0 switch. It includes MDC, SANit (SAN management software) and PCIe 2.0
switch. SW16 provide more options for users to choose SAN management software
but not SANit.
2. Q: Why is my disk LED status RED?
A: This is likely caused by a faulty hard drive. Replace the faulty drive as soon as
possible to protect your data.
3. Q: After an array has been created in RAIDGuard X, but the host does not find the
array volume.
A: Please check the LUN Mapping to ensure the array volume has been corrected
mapped to a LUN. If this is not the case, try restarting the system and it will be
automatically recognized. Once LUN is assigned, you can perform formatting and
mounting.
4. Q: What does the eight LEDs on the Host Bus Adapter mean?
A: The eight LED indicate the connection status of the HBA (The LED closest to the
bracket does not light up.) If you have properly connected the HBA to the B08S2-PS
RAID controller, one set of 4 consecutive LEDs will be constantly lit. The second set of
4 consecutive LEDs indicates the type of PCIe connection - flashing LEDs indicate a
PCIe Gen1 connection, while solid LEDs indicate a PCIe Gen2 connection.
5. Q: Why doesn’t the performance reach the expected levels while testing the B08S2-
PS? Why isn't the performance steady enough?
