)—A RAID 60 array is similar to a RAID 50 array
except that it includes four independent sets of parity data instead of two.
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.
Adding a Battery Backup Module
This table shows the battery model supported by your Adaptec RAID controller.
To purchase a battery backup module, refer to
the Adaptec Web site at www.adaptec.com.
Upgrading the Controller Firmware
To upgrade the firmware on your Adaptec RAID controller, follow the instructions in Using the
Adaptec Flash Utility on page 104. You can also use the Adaptec Storage Manager to upgrade
your controller firmware, refer to the Adaptec Storage Manager User’s Guide for Internal RAID
Storage.
