Fully Worked Example
In this section we will work through a complete multi-site, multi-region D2D design, configuration and deployment
tuning. The following steps will be undertaken:
Hardware and site configuration definition
Backup requirements specification
Using HP StorageWorks Backup sizing tool
–
size the hardware requirements, link speeds and likely costs
Work out each D2D Device configuration NAS, VTL, number of shares, and so on, using best practices that
have been articulated earlier in this document.
Configure D2D source devices and replication target configuration
Map out for sources and target the interaction of backup, housekeeping and replication.
Fine tune the solution using replication blackout windows and housekeeping blackout windows
The worked example below may seem rather complicated at times but it is specifically designed to tease out
many different facets of the design considerations required to produce a comprehensive and high performance
solution.
Hardware and site configuration
Please study the example below, it consists of four remote sites (A, B, C, D) with varying backup requirements
and these four remote sites replicate to a Data Center E over low bandwidth links. At the data Center E a larger
D2D Device is used as both the replication target (for sites A, B, C, D) and to back up local servers at site E.
