10.3 VTL Configuration
1. Select the check box to enable, or clear the check box to disable, the following settings:
Enable Opportunistic Locking - (Enabled by default) Opportunistic locking lets clients
lock files and locally cache information without the risk of another user changing the file.
This increases performance for many file operations, but it may decrease performance in
other operations because the server that grants the opportunistic lock must manage the
breaking of that lock when another user requests access to the file.
System performance may decrease if Opportunistic Locking is disabled.
Enable SMB Server signing - (Disabled by default) SMB server signing improves
security on Windows networks by requiring clients to provide a security signature to
connect to a server. If the ETERNUS CS800 is joined to a Windows domain that is
configured to require signing, you should enable SMB server signing.
2. Click Apply .
10.3 VTL Configuration
The VTL page allows you to configure the ETERNUS CS800 to present its storage capacity
as VTL (virtual tape library) partitions that are compatible with standard backup applications.
You can add virtual tape drives and storage slots to VTL partitions, as well as create and
work with virtual tape cartridges. You can also map partitions to hosts.
Additional Information
Virtual Tape Library (VTL) is available only on the ETERNUS CS800 VTL and Multi-Protocol
configurations.
The VTL wizard provides guided assistance for configuring VTL partitions (see
"Configuration Wizards" on page 145 ).

10.3.1 Partitions
The Partitions page allows you to manage VTL partitions on the ETERNUS CS800. Use
partitions to allocate the virtual tape drives and storage elements to separate partitions that
can be accessed by different host systems.
