StorageLink Platinum Edition (starting with version 2.0) provides Site Recovery, which provides a framework for
replicating and switching over a StorageLink-managed deployment of application storage resources, physical
hosts, and virtual machines to another location. Site Recovery enables organizations to implement fully
automated disaster recovery plans for fast, reliable site recovery of critical virtual infrastructure. Site Recovery
also supports failback to the primary site after a failover to the secondary site. The Backup and Recovery plug-in
is integrated with NetApp SnapMirror replication technology, which preserves the deduplicated storage savings
from the source to the destination storage array. Deduplication is then not required to be rerun on the destination
storage array. Additionally, when a Citrix XenDesktop environment is replicated with SnapMirror, the replicated
data can be quickly brought online to provide production access in the event of a site or data center outage. Citrix
StorageLink site recovery integrates NetApp FlexClone technology to instantly create zero-cost writable copies of
the replicated virtual desktops at the remote site that can be used for DR testing or for test and development
work. For more information on SnapMirror, refer to NetApp TR-3446: SnapMirror Best Practices Guide and Citrix
StorageLink user guide.

3.4.13 Storage Sizing Best Practices
Storage estimation for deploying Citrix XenDesktop solutions on NetApp includes the following:
●
Gather essential solution requirements
●
Perform performance-based and capacity-based storage estimation
●
Get recommendations on storage system physical and logical configuration
3.4.13.1 Gather Essential Solution Requirements
The first step of the storage sizing process is to gather the solution requirements. This is essential to size the
storage system correctly in terms of the model and the number of required NetApp storage controllers, type and
quantity of disk spindles, software features, and general configuration recommendations.
The main storage sizing elements are:
