VMWare Site Recovery Manager Demonstration - Part 1

This video walks through the configuration and testing of VMware's Site Recovery Manager. SRM allows you to quickly and easily create, test, and execute your virtualization DR strategy. The process is completely automated and allows for testing of the DR plan with no impact to production.

This video is split into two segments. This is part 1.

PART I : Site Recovery Manager with vRPAs

This is an incredibly sophisticated local and remote continuous data protection product, now available for people to try as a Virtual Machine.

This video covers configuring VMware Site Recovery Manager with vRPAs. In a nutshell? It's the same as the real thing :-)

PART 3


A database availability group (DAG) is a set of up to 16 Microsoft Exchange Server 2010 Mailbox servers that provide automatic database-level recovery from a database, server, or network failure. Mailbox servers in a DAG monitor each other for failures. When a Mailbox server is added to a DAG, it works with the other servers in the DAG to provide automatic, database-level recovery from database, server, and network failures.

When creating a DAG, you provide a unique name for the DAG of up to 15 characters. In addition to providing a name for the DAG, you must also assign one or more IP addresses (either IPv4 or both IPv4 and IPv6) to the DAG. The IP addresses you assign must be on the subnet intended for the MAPI network and must be available for use. You can assign static IP addresses to the DAG by using the DatabaseAvailabilityGroupIpAddresses parameter. If you use the Exchange Management Console (EMC) to create the DAG, or if you use the New-DatabaseAvailabilityGroup cmdlet without the DatabaseAvailabilityGroupIpAddresses parameter, the task will configure the DAG to use Dynamic Host Configuration Protocol (DHCP) to obtain the necessary IPv4 addresses. If you don't want the DAG to use DHCP, you can use the Set-DatabaseAvailabilityGroup cmdlet to configure one or more IP addresses for the DAG after it has been created. If your system is configured to use IPv6, the task will also attempt to automatically assign the DAG one or more IPv6 addresses.

Optionally, you can also specify a witness server and witness directory. If you do specify a witness server, we recommend that you use a Hub Transport server. This allows an Exchange administrator to be aware of the availability of the witness.

The following combinations of options and behaviors are available:

You can specify only a name for the DAG and leave the Witness Server and Witness Directory check boxes cleared. In this scenario, the wizard will search for a Hub Transport server that doesn't have the Mailbox server role installed. It will automatically create the default directory and share on that Hub Transport server and use that server as the witness server.

You can specify a name for the DAG, the witness server that you want to use, and the directory you want created and shared on the witness server.

You can specify a name for the DAG and the witness server that you want to use, and leave the Witness Directory check box cleared. In this scenario, the wizard will create the default directory on the specified witness server.

You can specify a name for the DAG, leave the Witness Server check box cleared, and specify the directory you want created and shared on the witness server. In this scenario, the wizard will search for a Hub Transport server that doesn't have the Mailbox server role installed, and it will automatically create the specified directory on that server, share the directory, and use that Hub Transport server as the witness server.  UPDATED: 2-14-12 PUTTING ALL TOGETHER.
