Connecting to the StoreOnce Backup system from the backup application

Make sure you have the latest version or software patches for the backup application. Please see
http://www.hp.com/go/ebs
Stop and restart the backup application services after the backup device has been discovered. If
you still cannot access the device, check Device Manager to make sure it is accessible from the
host.
For iSCSI devices: Make sure that the iSCSI initiator is connected to the devices and log on
to them, if they are not, configure them on the Targets tab of the iSCSI Initiator.
For FC devices: Models with an 8Gb FC card have a theoretical limit of 255 devices per FC
port on a host or switch.
NOTE: There are practical limitations on the number of devices that each host and FC switch or
HBA can access. It is possible to configure more drive and library devices than a host can access.
The limit for Windows or Linux hosts using the iSCSI interface is 64. Although the Fibre Channel
connection supports a greater theoretical number of devices per FC port on a host or switch, it is
recommended that no more than 64 devices are configured for use by a single host.

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 HP StoreOnce Backup system Concepts and Configuration Guidelines document on the HP
Support page for your product for detailed guidance.
There are many reasons why you may not see the performance you expected from your HP
StoreOnce Backup system.
Your own network speed or disk access is not fast enough to allow streaming of data.
Your backup application is not optimized.
Your HP Backup system is not optimized for your network and application.
You are not using the 10GbE ports for backup. Make sure that the media servers and PCs
are configured correctly to select the 10GbE network for data transfer.
The LEDs on the 10GbE card (at the rear of the HP StoreOnce Backup system) also help identify
network activity. Or use iLO to monitor the network ports.
Network
For iSCSI devices the HP StoreOnce Backup system is designed to be run on a 1Gb or 10Gb (if
model has 10GbE card installed) network. Performance will be reduced if a 100BaseT network is
used. Warnings on the StoreOnce GUI will indicate the network speeds at which the device is
operating.

Power up and power off

There are no commands within the GUI to control the power off or reboot the appliance. All the
commands should be run from the StoreOnce CLI.

Powering up servers

Power up the server using the power on button on the server to trigger a cold boot and automatically
power up.
The normal boot sequence can take up to 10 minutes. On power up the HP StoreOnce Backup
system runs its fans at high speed for approximately 10 seconds before returning to normal speed.
When powering off the HP StoreOnce Backup system make sure no backup or restore jobs are
running or scheduled to run while the HP StoreOnce Backup system is out of action.
