A Extra information for G1 products
Overview
The information in this section is for users who have one of the older G1 products:
•
HP D2D2502/2503/2504 G1 Backup Systems
•
HP D2D4004/4009 G1 Backup Systems
•
HP D2D4112 G1 Backup Systems
How do I know whether I have a G1 or G2 Backup System?
The generation can be identified from the Summary page and the Software page of the Web
Management Interface. Look at the Type field, which will state G1 or G2 or look at the Software
Revision field. If it shows 1.x.xx software, it is a G1 product; if it shows 2.x.xx software, it is a G2
product.
Major differences
This section highlights areas where the information provided in the main body of this user guide
is different for G1 products. It does not provide a definitive list of technical differences. Please refer
to the product specs for detailed information.
VTL devices
G1 products do not support ESL-e or EML-e library emulation and never support more than four
drives per library. There may be other restrictions on emulation types that are available depending
upon product type. Unsupported emulation types are not available for selection on the Devices
page. The maximum number of libraries and drives that are supported per G1 appliance is given
in the following table.

NOTE:
It is only possible to exceed the maximum physical limitation of 64 devices when
configuring the HP D2D4112 Backup System.
Creating cartridges
The procedure is as described in the main guide, apart from the following note that applies if you
are using Tape Attach.
NOTE:
When you import a cartridge, you need an empty mail slot and an empty cartridge to
which the backup application can move the imported data. Therefore, you may wish to leave a
slot whose cartridge has been exported empty, rather than creating a new cartridge. Or to create
a slot, edit the Total No Of Cartridge Slots on the Devices page.
NAS devices
G1 products do not support NFS NAS shares; they only support CIFS NAS shares.
