3. For Redundant Storage Types, you must select a redundancy level for each tier unless the drive type or size requires a specific

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.

Steps

1. Select the checkbox of each type of port you want to configure. 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.

Configure Fibre Channel Ports

For a Storage Center with Fibre Channel front-end ports, the Review Fault Domains page displays information about the fault domains

that were created by the Storage Center.

Prerequisites

One port from each controller within the same fault domain must be cabled.

NOTE:

If the Storage Center is not cabled correctly to create fault domains, the Cable Ports page opens and explains

the issue. Click Refresh after cabling more ports.

Steps

1. Review the fault domains that have been created.

2. (Optional) Click Copy to clipboard to copy the fault domain information.

3. (Optional) Review the information on the Zoning, Hardware, and Cabling Diagram tabs.

NOTE: The ports must already be zoned.

4. Click Next.

Configure iSCSI Ports

For a Storage Center with iSCSI front-end ports, verify iSCSI cabling and then enter network information for the fault domains and ports.

Prerequisites

One port from each controller within the same fault domain must be cabled.

Steps

1. Review the information on the iSCSI - Cable Ports page. If the Storage Center is not cabled correctly to create fault domains, fix the

cabling and click Refresh

2. Click Next.

TheSet IPv4 Addresses for iSCSI Fault Domain 1 page opens.
