NetApp Deduplication for FAS and V-Series Deployment and Implementation Guide

5.3 DEDUPLICATION ARCHIVE OF VMWARE

Deduplication has proven very useful in VMware archive environments. Figure 9 shows an example.

Figure 9) Archive of VMware with deduplication.

Detailed specifications for the example shown in Figure 9:

In this environment, VMware is done using NFS.

This environment uses approximately 1,800 clone copies of their master VMware image. These images

are used to create virtual machines for primary applications and for test and development purposes.

All 1,800 clone copies (~32TB) are stored on a FAS3070 in the Houston data center.

The data is mirrored to the remote site in Austin for disaster recovery.

Once per hour, the FAS3070 images are transferred to an R200 by using SnapMirror.

Deduplication is run nightly on the R200, and the VMware images are reduced in size by 80 to 90%.

6 DEDUPLICATION AND SHAREPOINT

If SharePoint

and NetApp deduplication for FAS will be used together, the following should be taken into

consideration:

Make sure that there is space available in the volume before using the ―sis on‖ command. If the ―sis on‖

command is used on a flexible volume that already has data and is completely full, it will fail. Up to 6%

of the total data size is needed for deduplication of metadata files.

Deduplication is transparent to SharePoint. The block-level changes are not recognized by SharePoint,

so the SharePoint database will be unchanged in size, even though there are capacity savings at the

volume level.
