In the event of a CommServe disaster, you can perform a Disaster Recovery Backup from the
CommCell and then use the CommServe Disaster Recovery Tool to restore the database metadata and
windows registry.
Data partitioning
The storage administrator can create a policy to store user data for a given user or group of users on a
designated set of tape cartridges in the LTS library. Conversely, the administrator can physically
partition the LTS library tier to store data for different group of users. To accomplish this task,
configure the ML6000 into several logical libraries and present them as multiple storage resource
libraries.
Data sharing
The storage administrator can provide a way for users to share their data with other system users or
groups by using the User Administration and Security feature of Simpana 9.
System users can share data with other users who have access to the primary storage tier.
Shared data is still subject to migration policies as defined by the storage administrator.
Performance and capacity scalability
Expansion of the LTS tier should not cause any major interruption to the existing system. The
expansion includes expanding for capacity, performance, or both. This can be achieved with the
capacity on demand feature of the ML6000 library along with slot increment software license key
allowing for non-disruptive scalability.
Data encryption
The Advanced Encryption Standard (AES) in 128, 192, 256 bit encryption is desired to be available for
data that resides on LTS tier. Simpana 9 supports many data encryption algorithms including Blowfish,
AES, Serpent, Twofish and 3-DES. Data is encrypted according to the method you select when
you(client-level encryption) or(auxiliary copy-level encryption). You can select from several algorithms and
key lengths.
Data compression
The storage administrator can compress data on LTS tier. You can achieve this by means of software
compression on the subclient level, which includes options to compress the data in the
Client/MediaAgent or hardware compression for libraries with tape media. This is supported by ML6000
library / LTO5 drives in a 2:1 ratio.
Reporting
The storage administrator needs a reporting capability to study overall status of the storage system and
health. The administrator needs the ability to generate reports on primary tier utilization. You can
achieve this through generating the Library and Drive Report and Storage Information Report.
Primary to LTS tier data movement and policies
Migration occurs transparently to the LTS tier based on policies defined by the storage administrator. A
stub is left behind for users to see and use through persistent recovery.
A Recall is initiated if the user opens the file for view or edit. The file is recalled from the LTS tier
back to the primary tier.
