Using the 10Gb ports (HP D2D4300 Series only) Although a warning will be displayed, it is possible to disable network ports. You can recover this only from the console screen by directly attaching a monitor and keyboard to the HP StoreOnce Backup System. • If you cannot use the Web Management Interface, check that the 1Gb ports are enabled on the Network (Configuration) page. • If data transfer seems slow, check that the 10Gb ports are enabled on the Network (Configuration) page. Also, make sure that the hosts are configured correctly to select the 10Gb network for data transfer. The LEDs on the 10Gb card (at the rear of the HP StoreOnce Backup System) also help identify network activity. Or use iLO2 to monitor the network ports. Performance Your HP StoreOnce Backup System is designed for high performance backup and restore operations according to the specification documented. However, it requires careful configuration. Please refer to the D2D Best Practices for VTL, NAS and Replication implementations document on the HP Manuals page for detailed guidance. There are many reasons why you may not see the performance you expected from your HP D2D. • Your own network speed or disk access is not fast enough to allow streaming of data. • Your backup application is not optimized. • Your HP D2D is not optimized for your network and application.

Using the 10Gb ports (HP D2D4300 Series only)
Although a warning will be displayed, it is possible to disable network ports. You can recover this
only from the console screen by directly attaching a monitor and keyboard to the HP StoreOnce
Backup System.
•
If you cannot use the Web Management Interface, check that the 1Gb ports are enabled on the
Network (Configuration) page.
•
If data transfer seems slow, check that the 10Gb ports are enabled on the Network (Configuration)
page. Also, make sure that the hosts are configured correctly to select the 10Gb network for data
transfer. The LEDs on the 10Gb card (at the rear of the HP StoreOnce Backup System) also help
identify network activity. Or use iLO2 to monitor the network ports.
Performance
Your HP StoreOnce Backup System is designed for high performance backup and restore operations
according to the specification documented. However, it requires careful configuration. Please refer
to the
D2D Best Practices for VTL, NAS and Replication implementations
document on the HP Manuals
page for detailed guidance.
There are many reasons why you may not see the performance you expected from your HP D2D.
•
Your own network speed or disk access is not fast enough to allow streaming of data.
•
Your backup application is not optimized.
•
Your HP D2D is not optimized for your network and application.
Network
For iSCSI devices the HP D2D is designed to be run on a 1Gb or 10Gb (HP D2D4300 Series) network.
Performance will be reduced if a 10/100BaseT network is used. The LEDs on the front panel (1
–
Gb
ports only) and on the network ports and also warnings on the Web Management Interface will
indicate the network speeds at which the device is operating.
Web Management Interface errors and warnings
The Web Management Interface will highlight errors and warnings associated with the operation of
the HP D2D.
•
You can configure email alerts, which will automatically send a message to your mail system when
a problem occurs (see
“
Email Alerts (Configuration)
”
on page 56).
•
The
Summary
page of the Web Management Interface can indicate an error or warning message,
highlighted by an information, a warning or an error icon against major sub systems. See
Status
icons
on page 13.
•
The System Event Log in the Web Management Interface can also highlight warnings or errors.
See
“
Log (Status)
”
on page 72.
