How to plan single instance storage
Enterprise Vault can use single instance storage to optimize archive storage space. Enterprise Vault's single instance storage mechanism archives a single instance of parts of an item that are suitable for sharing, such as large message attachments. Enterprise Vault can share the single instance storage parts (SIS parts) within a vault store, or across two or more vault stores within a vault store group. A vault store group forms an outer boundary for sharing.
If you use Enterprise Vault's single instance storage mechanism, you need to create a sharing regime that meets your organization's data sharing requirements and which is appropriate for your network connection speeds. Consider what sort of sharing regime you require before you start archiving. Enterprise Vault cannot share items retrospectively. Also there are limits to what you can change after Enterprise Vault has started sharing items.
Note the following:
. Enterprise Vault single instance storage is not performed when items are stored to partitions that are hosted on Dell EMC Centera devices. You can configure a partition for a Dell EMC Centera device to use the Centera's device-level sharing mechanism, if required. Enterprise Vault then stores the shareable parts of a saveset as separate data blobs, so that the Centera device is able to share them.
. Enterprise Vault shares the SIS parts between items in the same smart partition, but it does not share the SIS parts between a smart partition and other partitions.
For example, suppose that two employees receive the same email, which has an attachment. For compliance reasons, Enterprise Vault archives one employee's emails to a smart partition; it archives the other employee's emails to the standard vault store partition. If Enterprise Vault first archives the email and its attachment to the standard partition then, when it subsequently archives the email to the smart partition, it should not normally archive the attachment again. This would mean that the data on the smart partition is not fully compliant, however, so in this case Enterprise Vault archives both the email and the attachment again.
For more information about setting up single instance storage, see "Setting up Storage" in Installing and Configuring.
