Connecting To The Storeonce Backup System From The Backup Application; Performance - HP StoreOnce 2700 Installation And Configuration Manual

LACP. Similarly, if you were using LACP and have changed to another mode, you must disable
LACP on both the network switch and the StoreOnce appliance.
7. If you still cannot access the HP StoreOnce Backup system, contact HP Support.

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 StoreOnce Catalyst devices, make sure you have the required plug-in installed on the host
media server.
For StoreOnce VTL devices, make sure you have the required drivers installed on the host
media server.
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; models with 4Gb FC card have a theoretical limit of 127 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.
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 10 Gbit ethernet ports for backup. Make sure that the media servers
and PCs are configured correctly to select the 10 Gbit ethernet network for data transfer.
The LEDs on the 10 Gbit ethernet card (at the rear of the HP StoreOnce Backup system) also
help identify network activity. Or use iLO to monitor the network ports.
NOTE: The HP StoreOnce 2700 Backup system does not have a 10 Gbit ethernet card.
Network
For iSCSI devices the HP StoreOnce Backup system is designed to be run on a 1Gb or 10Gb (if
model has 10 Gbit ethernet 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.
