Adding Enhanced Features
As your storage needs change, you can enhance data protection and improve performance by
upgrading your Adaptec controller with extra features.
Currently, Adaptec offers the snapshot function as an upgrade feature which can be activated
with a feature key (sold separately). A snapshot is a frozen image of a logical drive at a particular
point in time. You can use this feature to back up your data to tape, clone a disk drive, or copy
the data to multiple servers.
Note:
Snapshots are supported by Windows and Linux operating systems only.
To purchase a feature key, contact your Adaptec Reseller or refer to the Adaptec Web site at
www.adaptec.com. To unlock the enhanced features with a feature key (see the following
section).
Using a Feature Key to Unlock Enhanced Features
When you receive a feature key, use Adaptec Storage Manager to unlock the new features. For
step-by-step instructions, follow the instructions in the online Help or the Adaptec Storage
Manager User’s Guide
for Internal RAID Storage
on the Adaptec Storage Manager Installation CD.
