Administrator Guide

• If one or more of the system setup tasks fails, click Troubleshoot Initialization Error to learn how to resolve the issue.
• If the Configuring Disks task fails, click View Disks to see the status of the drives detected by the Storage Center.
• If any of the Storage Center front-end ports are down, the Storage Center Front-End Ports Down dialog box opens. Select the
ports that are not connected to the storage network, then click OK.
2. When all of the Storage Center setup tasks are complete, click Next.
Enter Key Management Server Settings
Specify key management server settings, such as hostname and port.
Steps
1. In the Hostname field, type the host name or IP address of the key management server.
2. In the Port field, type the number of a port with open communication with the key management server.
3. In the Timeout field, type the amount of time in seconds after which the Storage Center should stop attempting to reconnect to the
key management server after a failure.
4. To add alternate key management servers, type the host name or IP address of another key management server in the Alternate
Hostnames area, and then click Add.
5. If the key management server requires a user name to validate the Storage Center certificate, enter the name in the Username field.
6. If the key management server requires a password to validate the Storage Center certificate, enter the password in the Password
field.
7. Click Browse next to the Root CA Certificate. Navigate to the location of the root CA certificate on your computer and select it.
8. Click Browse next to the certificate fields for the controllers. Navigate to the location of the controller certificates on your computer
and select them.
9. Click Next.
Create a Storage Type
Select the datapage size and redundancy level for the Storage Center.
Steps
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 I/O. Selecting this size increases overhead and reduces the maximum available
space in the Storage Type. All-flash storage systems 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. Select a redundancy type.
• Redundant: Protects against the loss of any one drive (if single redundant) or any two drives (if dual redundant).
• Non-Redundant: Uses RAID 0 in all classes, in all tiers. Data is striped but provides no redundancy. If one drive fails, all data is lost.
NOTE:
Non-Redundant is not recommended because data is not protected against a drive failure. Do not use non-
redundant storage for a volume unless the data has been backed up elsewhere.
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.)
