Create a Storage Type

Select the datapage size and redundancy level for the Storage Center.

1. Select a datapage size.

• Standard (2 MB Datapage Size): Default datapage size, this selection is appropriate for most applications.

• High Performance (512 KB Datapage Size): Appropriate for applications with high performance needs, or in environments

in which snapshots are taken frequently under heavy IO. Selecting this size increases overhead and reduces the maximum

available space in the Storage Type. Flash Optimized storage types use 512 KB by default.

• High Density (4 MB Datapage Size): Appropriate for systems that use a large amount of disk space and take snapshots

infrequently.

2. Modify the redundancy for each tier as needed.

• For single-redundant RAID levels, select Redundant.

• For dual-redundant RAID levels, select Dual Redundant.

3. To have the system attempt to keep existing drives on the same redundancy level when adding new drives, select the Attempt

to maintain redundancy when adding or removing disks check box.

4. Click Next.

Congure Ports

Use the Congure Fault Tolerance pages to congure the system ports.

1. Select Congure Fault Domains next to Fibre Channel, SAS or iSCSI to set up fault domains for those ports. If the system has

both Fibre Channel and iSCSI ports, select Congure Fault Domains next to both port types.

2. Click Next.

Congure Fibre Channel Ports (Congure Storage Center Wizard)

Create a Fibre Channel fault domain to group FC ports for failover purposes.

1. On the rst Congure Fibre Channel Fault Tolerance page, select a transport mode: Virtual Port or Legacy.

2. Select the method for creating fault domains:

• Generate Fault Domain Conguration – One of the following fault domains is created, depending on system conguration

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 Conguration, proceed to step 5.

4. If you selected Specify Number of Fault Domains, congure 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 conguring more than one fault domain, repeat these steps for each domain.

5. On the nal Congure 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.

• Click Remove to delete a fault domain.

7. Click Next.
