E-LTU NAS and VTL backup targets 3.x.x StoreOnce software continues to support NAS (CIFS and NFS) and VTL (Virtual Tape Library) functionality that was previously available in products running 2.x.x software. There are small differences in the VTL emulation types available in 3.x.x software, so your backup application will need to be re-configured after the conversion. In addition previously configured WWNN and WWPN values will be different after the conversion, so Fibre Channel switch re-configuration will be required. NAS and VTL Replication Replication functionality for NAS and VTL devices is present in 3.x.x software and is compatible with both older single node appliance software and B6200 multi-node appliances. Replication offers a way that you can migrate previously backed up data onto your appliance after conversion to 3.x.x software completes. License Compatibility Licenses for Capacity upgrade and Replication that were purchased for use on your existing appliance are also valid after the conversion to 3.4.x (or later) software. Your appliance will retain its existing serial number so your node-locked licenses can continue to be used. In addition, after the conversion, you can purchase licenses to use the Catalyst functionality. Installation on disk Existing single node products running 2.x.x software boot and run from a flash memory device located inside the appliance chassis. 3.4.x (or later) software, however, is installed on the appliance hard disks. The installation process is outlined below. Note also that the capacity available for backup is smaller after the installation of 3.4.x (or later) software due to installing the software on disk. RAID Configuration Because the system software is now installed on the hard disks in the appliance there is some capacity reduction for non-expanded StoreOnce appliances. (See Comparison of usable capacity (page 9).) However, because the 3.x.x software does not configure a spare disk in the RAID configuration, the available capacity of expanded appliances is the same or higher than appliances running 2.x.x software. StoreOnce CLI The Single Node appliances running 3.4.x (or later) software deliver a customer-accessible, enterprise class CLI interface as well as the GUI. This StoreOnce CLI is used for several configuration tasks and also for day to day administration of some features of the StoreOnce appliance.
