54. Select the Destination Celerra Network Server

NOTE: By default, the local (SOURCE) Celerra is selected in the dialog. You must change this to the
remoet (TARGET) Celerra to select your target iSCSI LUN.

55. Enter the Replication Details

56. Be sure to enter a name that informs you of the direction of replication.

Note: The size of the source and destination LUNs are the same. If the LUNS are of different size, or
if the target LUN is not set to 'Read-Only, the replication will fail to establish.

57. Click Help for a description of any of the fields.
58. Click OK.
59. Verify the Replication Created Without Errors

60. Verify the Replication on the Remote Celerra VSA

SECTION 5.3 - Advanced Use-Cases (SRM in a Box)
One of the advantages of using the Celerra VSA is that you can deploy two UBER VSAs and setup a
VMware SRM (Site Recovery Manager) environment to emulate a Disaster Recovery scenario by
replicating virtual machines from one VSA to the other. SRM is an automated Disaster Recovery
failover runbook and testing tool. The Celerra VSA enables a user to emulate a failover without needing
two separate physical hosts. If you are unfamiliar with SRM, please read about it at the following site:
http://www.vmware.com/products/site-recovery-manager/.

You will need to install the two VSA’s as well as two instances of VCenter, one ESXi node per
VCenter instance and some additional networking. You will also want to install a few VM’s within
each ESXi node. All this can be done within Workstation. Nick Weaver has produced an
informative video on the full setup and testing here: http://nickapedia.com/2010/10/07/lights-
camera-replication-uber-srm-video-guide/

The video contains an overall diagram of the “SRM in a Box” configuration. This configuration is
comprised of a ‘Production Site’ and a ‘Recovery Site’. Within each site is a VCenter instance, an
SRM instance, a Celerra VSA and an ESXi server. You will also see that there are some VMs setup
within the ESXi servers. The diagram also shows the four separate networks required in order to
separate Management, Storage, VM, and Replication traffic.
