3. SAN Functions
Server Linkage Functions
The controller firmware version of the ETERNUS DX must be V10L86 or later.
•
• The Veeam Storage Integration license must be obtained and registered in the ETERNUS DX.
• iSCSI and FC host interfaces are supported in Veeam Storage Integration for the connection
between backup proxies and the ETERNUS DX.
• To connect a Backup Proxy with the ETERNUS DX via an FC, the host affinity settings must be
configured for the Backup Proxy using ETERNUS CLI. For more details, refer to "ETERNUS CLI
User's Guide".
• For a restore process using a host that does not have any LUNs attached, host affinity settings
for the host must be configured in advance. For more details, refer to "ETERNUS CLI User's
Guide".
• To enable the ETERNUS DX storage snapshot integration with Veeam Backup & Replication,
FUJITSU Plug-In for Veeam Backup & Replication must be installed to the Veeam backup serv-
er.
• If a volume has several snapshot generations and these snapshots have been created with dif-
ferent resolutions, only the oldest snapshot generation can be deleted.
• The following volumes cannot be managed or operated by Veeam Backup & Replication:
- Volumes in the Secondary storage used for the Storage Cluster function
Virtual Volumes (VVOLs)
-
Volumes with Advanced Copy sessions except SnapOPC+ sessions
-
Volumes with SnapOPC+ sessions created by ETERNUS SF AdvancedCopy Manager
-
• Although the volumes in the Primary storage used for the Storage Cluster function can be
managed by Veeam Backup & Replication, note the following points.
- If the Storage Cluster function's failover is performed, the Veeam Backup & Replication job or
operation may fail. After a failback, re-perform the job or operation that failed.
- Failover cannot be performed while Instant VM Recovery or SureBackup is running.
Veeam Backup & Replication jobs or operations may fail during a RAID migration, a Thin Provi-
•
sioning Volume balancing, or a Flexible Tier Pool balancing.
SnapOPC+ is used for Veeam Storage Integration.
•
Thin Provisioning Volumes (TPVs) or Flexible Tier Volumes (FTVs) are used as SnapOPC+ copy
destination volumes.
Configure an appropriate maximum pool capacity for the Thin Provisioning function by taking
the total capacity of volumes used for Veeam Storage Integration and the number of snapshot
generations into consideration.
For more details about the maximum pool capacity setting, refer to "Thin Provisioning Pool
Management" in "ETERNUS Web GUI User's Guide".
Guidelines for the maximum pool capacity for the Thin Provisioning function:
Maximum pool capacity ³ total capacity of TPVs and FTVs + total capacity of volumes for
Veeam Storage Integration ´ (number of snapshot generations + 1)
It is not recommended to use multiple Veeam Backup & Replication for managing a single
•
ETERNUS DX. In such configuration, an error might occur at the jobs that are in conflict with
each other when being executed from multiple Veeam Backup & Replication.
