Supported Application and Database Servers

The Replication and High Availability solutions are custom-tailored for the following application and database servers, for both 32-bit and 64-bit Windows:

• File Server
• Microsoft Exchange
• Microsoft SQL
• Microsoft IIS
• Oracle
• Microsoft SharePoint
• Microsoft Hyper-V
• VMware vCenter Server
• CA ARCserve RHA Control Service
• Microsoft Dynamics CRM

CA ARCserve RHA can also transfer full systems to virtual machines. For an up-to-date list of supported platforms and applications, see the CA ARCserve RHA Supported Configurations document at the CA Support website.

Important! For all supported servers, you must statically assign all IP addresses (DHCP-assigned IP addresses on the Master or Replica server are not supported).

File Server Replication and High Availability

This section describes the requirements for running CA ARCserve RHA for File Server.

File Server Requirements

To implement High Availability procedures for File Server, you need to have the following configurations:

• Two servers running supported Windows Server with the same level of service packs and hot fixes installed.

  Note: For a complete list of supported operating systems and applications, see the CA ARCserve RHA Release Notes.

• (In the same Active Directory environment) Both Master and Replica servers should reside in the same Active Directory forest, and be members of the same domain or trusted domains.
• Statically assign all IP addresses (DHCP-assigned IP addresses on the Master or Replica server are not supported).
• The protected server is not a domain controller or DNS server.

File Server Log On Account

The CA ARCserve HA service log on account must satisfy all of the following account conditions:

• It is a member of the Domain Admins group. If the Domain Admins group is not a member of the built-in domain local group Administrators you must use an account that is.
• It is a member of the local machine Administrators Group. If the Domain Admins group is not a member, add the account manually.

File Servers Operating in a Workgroup

For servers in a workgroup, set the CA ARCserve RHA Engine service account to Local System (unless you have added any custom scripts that require higher level permissions). Servers in a workgroup can use Redirect DNS only with DNS servers that allow non-secure updates. You can use Move IP, Switch Computer Name, and custom redirection scripts normally.

Microsoft Exchange Server Replication and High Availability

This section describes the CA ARCserve RHA configuration requirements for Microsoft Exchange Server.

Exchange Server Replication

This section describes the requirements for running CA ARCserve RHA for Exchange Server.

Exchange Replication Configuration

To implement Replication for Exchange Server, you need to have the following configurations:

• Two servers running supported Windows Server with the same level of service packs and hot fixes installed.

  Note: For a complete list of supported operating systems and applications, see the CA ARCserve RHA Release Notes.

• Exchange Server installed on both Master and Replica servers, with the same edition, version, service packs and hot fixes installed on each.
• Exchange Server installed with the same login credentials on Master and Replica servers.
• Both servers should have the Mailbox and CAS roles installed. If the Master server is the only server in the Exchange organization that holds the CAS And HUB transfer roles, than the Replica server should have the identical Exchange Server roles installed.
• Both servers should have the identical version of PowerShell installed.
• Both servers should have the same Exchange Administrative Group.

Note: Exchange Server 2010 does not permit you to create two databases with the same name on Master and Replica servers, even if the database is dismounted. Use a name for the Replica database that is less than 64 characters long and follows this convention:

<ReplicaName>=<MasterName>_xxxx

Where xxx = random number.

Exchange Replication Log On Account

The CA ARCserve RHA Engine service log on account must meet all of the following conditions:

• Must be an Exchange View Only Administrator.
• Must be a member of the Administrators Group on the local machine.

Note: If your company's security policy requires even more granular permissions than described, contact CA technical support to receive detailed instructions on permissions required.

Exchange Replication Clusters

With CA ARCserve RHA, working with clusters is nearly identical to working with stand-alone servers. Simply enter the "Exchange Virtual Server Name" as the Master or Replica server name where appropriate.

On Exchange 2007, CA ARCserve RHA supports LCR deployments. No additional configurations are required.

Note: On Exchange 2007, CCR deployments are not supported.

High Availability for Exchange Server

This section describes the requirements for running CA ARCserve HA for Exchange Server.

Exchange HA Configuration

To implement Replication for Exchange Server, you need to have the following configurations:

• Two servers running supported Windows Server with the same level of service packs and hot fixes installed.

  Note: For a complete list of supported operating systems and applications, see the CA ARCserve RHA Release Notes.

• Exchange Server installed on both Master and Replica servers, with the same edition, version, service packs and hot fixes installed on each.
• Exchange Server installed with the same login credentials on Master and Replica servers.
• Both servers should have the Mailbox and CAS roles installed. If the Master server is the only server in the Exchange organization that holds the CAS And HUB transfer roles, than the Replica server should have the identical Exchange Server roles installed.
• Both servers should have the identical version of PowerShell installed.
• Both servers should have the same Exchange Administrative Group.

Note: Exchange Server 2010 does not permit you to create two databases with the same name on Master and Replica servers, even if the database is dismounted. Use a name for the Replica database that is less than 64 characters long and follows this convention:

<ReplicaName>=<MasterName>_xxxx

Where xxx = random number.

Exchange HA Log On Account

The CA ARCserve HA Engine service log on account must meet all of the following conditions:

• Must be a member of the Domain Admins group.
• Must be an Exchange Administrator.
• Must be a member of the Administrators Group on the Local machine.

Note: If your company's security policy requires more granular permissions than described, contact CA ARCserve RHA technical support to receive detailed instructions on the permissions required.

Exchange HA Clusters

With CA ARCserve HA, working with clusters is nearly identical to working with stand-alone servers. Simply enter the "Exchange Virtual Server Name" as the Master or Replica server name where appropriate.

On Exchange 2007, CA ARCserve HA supports LCR deployments. No additional configurations are required.

Note: On Exchange 2007, CCR deployments are not supported.

Microsoft SQL Server Replication and High Availability

This section describes the CA ARCserve RHA requirements for Microsoft SQL Server.

SQL Server Replication

This section describes the requirements for running CA ARCserve RHA for SQL Server.

SQL Replication Configuration

To implement Replication for SQL Server, you need to have the following configurations:

• Two servers running supported Windows Server with the same level of service packs and hot fixes installed.

  Note: For a complete list of supported operating systems and applications, see the CA ARCserve RHA Release Notes.

• An instance of SQL Server installed on the Master.

To use the Replication solution with the Assured Recovery option for SQL Server, you need to have the following configurations:

• The same version of Microsoft SQL Server installed on both Master and Replica servers.
• SQL Server installed with the same login credentials on Master and Replica servers.

Also, you must stop the SQL Server service on a Replica host when replication is active.

Note: If the SQL Master Database is not replicated, you can detach the replicated databases on the Replica server without stopping the Engine service.

SQL Replication Log On Account

The CA ARCserve RHA Engine service log on account must meet all of the following conditions:

• For stand-alone servers (i.e., non-clustered), use the default of Local System.
• For cluster nodes, use a service account that is a Local Administrator on all cluster nodes.

High Availability for SQL Server

This section describes the requirements for running CA ARCserve HA for SQL Server.

SQL HA Configuration

To implement High Availability procedures for SQL Server, you need to have the following configurations:

• Two servers running supported Windows Server with the same level of service packs and hot fixes installed.

  Note: For a complete list of supported operating systems and applications, see the CA ARCserve RHA Release Notes.

• One or more instances of Microsoft SQL Server installed on each server:
  • Both servers should have the same SQL version, service packs, and hot fixes installed.
  • Both servers should hold identical SQL Server instances, i.e., default or named.
  • Drive letters containing database files should be identical on both servers.
  • The full path to the default system database of each instance should be identical on both servers.
  • (In the Active Directory environment) Both Master and Replica servers should reside in the same Active Directory forest and be members of the same domain or trusted domains.
• Verify that the port defined in the Network Configuration TCP/IP properties of the SQL instance(s) is assigned statically and is identical on both Master and Replica.
• The protected server is not a domain controller or DNS server.

SQL HA Log On Account

The CA ARCserve HA Engine service log on account must satisfy all of the following conditions:

• It is a member of the Domain Admins group. If the Domain Admins group is not a member of the built-in domain local group Administrators, you must use an account that is.
• It is a member of the local machine Administrators Group. If the Domain Admins group is not a member, add the account manually.
• If the account does not have built-in Administrator permissions on all SQL Server instances, add appropriate permissions.

Note: If your company's security policy requires more granular permissions than described, contact technical support to receive detailed instructions. For servers in a workgroup, leave the log on user as Local System.
