3 For Redundant Storage Types, you must select a redundancy level for each tier unless the drive type or size requires a specic
redundancy level
• Single Redundant: Single-redundant tiers can contain any of the following types of RAID storage:
– RAID 10 (each drive is mirrored)
– RAID 5-5 (striped across 5 drives)
– RAID 5-9 (striped across 9 drives)
• Dual redundant: Dual redundant is the recommended redundancy level for all tiers. It is enforced for 3 TB HDDs and higher and for
18 TB SSDs and higher. Dual-redundant tiers can contain any of the following types of RAID storage:
– RAID 10 Dual-Mirror (data is written simultaneously to three separate drives)
– RAID 6-6 (4 data segments, 2 parity segments for each stripe)
– RAID 6-10 (8 data segments, 2 parity segments for each stripe.)
4 Drive Addition is selected by default. Leave this option selected.

Fault Tolerance
Set up Fibre Channel, iSCSI and SAS ports with redundant paths for fault tolerance.
1 Select the checkbox of each type of port you want to congure. You must select at least one type to continue.
NOTE: If a port type is grayed out, no ports of that type have been detected.
2 Click Next.
Congure Fibre Channel Ports
Create a Fibre Channel fault domain to group FC ports for failover purposes.
1 On the rst Congure Fibre Channel Fault Tolerance page, select a transport mode: Virtual Port or Legacy.
2 Select the method for creating fault domains:
• Generate Fault Domain Conguration – One of the following fault domains is created, depending on system conguration and
mode selected:
Transport Mode
One Controller Two Controllers
Virtual Port Two controller ports Two controller ports, one on each controller
Legacy One controller port Four controller ports, two on each controller
• Specify Number of Fault Domains – Set the number of fault domains to create.
3 Click Next.
NOTE
: If you selected Generate Fault Domain Conguration, proceed to step
5.
4 If you selected Specify Number of Fault Domains, congure each fault domain.
a In the Name eld, type a name for the fault domain.
b (Optional) In the Notes eld, type notes for the fault domain.
c In the Ports table, select the Fibre Channel ports to add to the fault domain. All FC ports in the fault domain should be
connected to the same FC fabric.
d Click Next. If you are conguring more than one fault domain, repeat these steps for each domain.
5 On the nal Congure Fibre Channel Fault Tolerance page, review the fault domain setup.
6 (Optional) To change the fault domain setup, select from the following options:
• Click Create Fault Domain to create a new fault domain.
• Click Edit Fault Domain to edit the current fault domain.
