Virtualized networking enables the ReadyDATA 5200 to service many separate networks and allows you to control how much
bandwidth is used for each storage-related task.
Write Throughput Performance
The most important performance metric to consider when designing a B2D solution is sequential write throughput. Throughput
dictates the amount of data that can be written to a storage system during backup operations. You can use throughput metrics to
calculate the amount of data that can be written within a backup window.
The following chart shows expected performance of write throughput based on number of drives.
Figure 6. ReadyDATA 5200 SATA drive sustained throughput
Note: This benchmark was created using SATA drives on a ReadyDATA 5200. Use of SAS drives or SSDs enhances performance but
is not ideal for backup-to-disk workloads due to the capacity constraints of SAS drives and SSDs.
Replication Considerations
To provide flexibility to meet your bandwidth constraints and recovery requirements, the ReadyDATA 5200 offers replication features
that support a variety of configurationsand network topologies.
Replication on the ReadyDATA 5200 allows periodic and constant replication between two or more ReadyDATA 5200 storage
systems. You can locate the systems on a private LAN or separate them using the Internet. When data is replicated over the Internet,
the ReadyDATA 5200 automatically encrypts it for secure transmission.
