Titan SiliconServer
•
A File System or directory within the same Titan SiliconServer. BlueArc’s
Multi-Tiered
Storage
(MTS) technology ensures that replications that take place within a Titan
SiliconServer are performed efficiently, without tying up network resources.
•
A File System, Virtual Volume, or directory on another Titan.
•
A File System, Virtual Volume, or directory on another SiliconServer model, e.g. the
Si8900.
Although the SMU schedules and starts all replications, data being replicated flows directly from
source to target without passing through the SMU.
Incremental Block-Level Replication
By default, Incremental Data Replication will copy files that have changed since the last
replication in their entirety. With the Block-Level Replication feature enabled, only data blocks
in large files that have been written since the last replication will be copied. Depending on the
use of files within the source volume, this could substantially reduce the amount of data copied.
The Block-Level Replication feature is automatically enabled by installing an IBR license.
Note:
Block-Level Replication copies the entire file if the file has multiple
hard links.
Note:
The Block-Level Replication feature is automatically enabled if the
Incremental Block Replication license is present.
Configuring Policy-Based Replication
Configuring a policy-based replication process requires the administrator to setup the following
processes.
❑
Replication Policy
- a replication policy identifies the data source, the
replication target, and optionally a replication rule. Pre-replication and post-
replication scripts can also be set up in the policy page.
❑
Replication Rules
- optional configuration parameters that allow replications to
be tuned to enable (or disable) specific functions or to achieve optimal
performance.
❑
Replication Schedule
- defines the schedule, timing and policy based on the
scheduled date and time.
