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) (page 43)). • 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 (page 9). • The System Event Log in the Web Management Interface can also highlight warnings or errors. See Log (Status) (page 57). TIP: If you have selected a language other than English and find that some of the messages are in English, you have upgraded the software without upgrading the language pack. This is easily remedied by following the instructions in (page 90). Best practice, however, is to always upgrade the language pack at the same time as the software. Disk RAID errors and warnings See Hard disk replacement (page 136) for details of hard disk drive failure and rebuild. Network warnings See Connecting to the network (page 125). NTP server fails If the NTP server (for automatic date and time update) fails to connect to the server for any reason, it will fail and stop the NTP server. If this happens an email alert will be sent and the user must manually restart NTP from the Web Management Interface. System state This describes the overall state of the HP D2D. RAM Failure Warning Your HP D2D is designed to operate with a certain amount of RAM. If it is outside this limit, a warning will appear. The device will still operate, but with very limited performance. • Check that the memory modules are correctly mounted in the slots • Check that you have the correct memory capacity inserted • Check that they are in the correct slots CPU Faulty Warning Web Management Interface errors and warnings 127

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) (page 43)
).
•
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
(page 9)
.
•
The System Event Log in the Web Management Interface can also highlight warnings or errors.
See
Log (Status) (page 57)

TIP:
If you have selected a language other than English and find that some of the messages are
in English, you have upgraded the software without upgrading the language pack. This is easily
remedied by following the instructions in
(page 90)
. Best practice, however, is to always upgrade

Disk RAID errors and warnings
See
Hard disk replacement (page 136)
for details of hard disk drive failure and rebuild.
Network warnings
See
Connecting to the network (page 125)
.
NTP server fails
If the NTP server (for automatic date and time update) fails to connect to the server for any reason,
it will fail and stop the NTP server. If this happens an email alert will be sent and the user must
manually restart NTP from the Web Management Interface.
System state
This describes the overall state of the HP D2D.
RAM Failure Warning
Your HP D2D is designed to operate with a certain amount of RAM. If it is outside this limit, a
warning will appear. The device will still operate, but with very limited performance.
•
Check that the memory modules are correctly mounted in the slots
•
Check that you have the correct memory capacity inserted
•
Check that they are in the correct slots
