The upgrade disables sharing
Enterprise Vault 8.0 uses
a new optimized single instance storage model.
See "Optimized single
instance storage" in the ReadMeFirst.
On upgrade, Enterprise Vault makes the following
changes in each Enterprise Vault site:
-
It creates a vault store group named the Default
Upgrade Group, and places all of the site's vault stores into that
group.
-
It sets the sharing level of each vault store in
the Default Upgrade Group to "No sharing".
Note:
|
If a
partition was configured to share archived items before the
upgrade, it no longer does so after the upgrade until you change
the vault store's sharing level from "No sharing".
|
Note:
|
Enterprise Vault does not employ optimized single
instance storage when items are stored to partitions that are
hosted on EMC Centera devices. Enterprise Vault 8.0 continues to
provide a separate device-level sharing option to take advantage of
the sharing capabilities of Centera.
|
Before you configure sharing with optimized single
instance storage, it is important to consider what sort of sharing
regime is suitable for your organization. For example:
-
You may need to keep parts of your organization
separated with information barriers, or firewalls.
-
Network connectivity between the required computers
must be sufficient to provide acceptable storage and retrieval
times.
There are limits to what you can change after you
have configured sharing. Changes to vault store sharing levels do
not act retrospectively. Also, you can only move a vault store into
a different vault store group if both of the following apply:
-
The vault store is one that Enterprise Vault
upgraded, or one that you created in the Default Upgrade Group.
-
The vault store's sharing level is "No sharing" and
has never been changed.
For information on how to
set up a suitable sharing regime, see the "Setting up storage"
chapter in Installing and Configuring.
