CA ARCserve RHA r16 Service Pack 2 › New Features and Enhancements
New Features and Enhancements
CA ARCserve RHA r16 Service Pack 2 supports the following features:
Restore Support to a Bare Metal Machine
Effective with this release, CA ARCserve RHA supports restoring data to a bare metal machine. You can restore to a bare metal machine (physical or virtual) either from a live system that has performed a failover/switchover or from a bookmark rewind point. This feature not only restores data but also builds the bare metal machine by installing the operating system, applications, and other necessary components.
A bare metal recovery provides the following benefits:
- Builds a machine exactly similar to the Master before restoring data
- Recovers data even to a dissimilar hardware
- Recovers data on a volume level
NAT Support
Effective with this release, you can deploy CA ARCserve RHA in a NAT (Network Address Translation) environment. This feature lets you have an RHA setup where host servers are behind a NAT device or a firewall. For example, you can have a setup where the Master is behind a NAT device whereas the Control Service and Replica are on a public domain.
To use this feature, CA ARCserve RHA provides the RHA NAT utility. You configure the RHA NAT utility on the host that is behind the NAT device.
The RHA NAT feature supports replication, restore, failover, and scenario management.
Enhancements
Effective with this release, CA ARCserve RHA provides the following enhancements:
- Volume Snapshot Management Support: The volume snapshot has been simplified and you can set volume snapshots at one place. In addition, you can specify whether you want to have a snapshot while creating a bookmark. A check box is available for this option while creating a bookmark.
- Advanced Bandwidth and I/O Throttling: The bandwidth scheduler is enhanced to configure hourly bandwidth settings for the entire week. For example, you can set 256 KB for Monday, 9:00 AM or 192 KB for Wednesday, 4:00 PM.
- Recover Active Server: Now Full System scenarios support the Recover Active Server function. You can use this function to simulate switchover or switchback.
- Start/Stop Virtual Machine: A new option on the Tools menu has been added to stop or start a virtual machine. This option is applicable for a Data Recovery or High Availability full system scenarios.
- Delete All VM Resources: A new option on the Tools menu has been added to delete temporary VM resources. This operation lets you delete temporary resources such as disk files, snapshots, and other temporary files.
- VMware Distributed Virtual Switch: Support for the VMware Distributed Virtual switch has been added for full system scenarios. You can select the vSphere Distributed Virtual Switch during network mapping.
- Proxy Support for Control Service: HTTP proxy support for RHA Control Service has been added. This service lets the Control Service connect to the RHA engine hosts using HTTP proxy servers.
- Data Rewind Performance: The rewind point query function is restructured and the user interface has been redesigned. You can quickly search event points during rewind. The response time is fast even when there are up to million events.
- Scheduled Bookmark: A new property, Enable Scheduled Bookmark, has been added to let you create a bookmark schedule for DB scenarios such as MSSQL and Exchange scenarios.
- CAVSSSoftProv Service: The CAVSSSoftProv service is no longer required.
- Log Collection Utility: A log collection utility has been added. This utility can automatically retrieve Master, Replica, and Control Service logs along with event logs from the Master and Replica.
- Create Application Consistent Snapshot: This feature lets RHA engine call application VSS writers, such as the Exchange VSS writer and MSSQL VSS writer, to create application consistent snapshots. The snapshots are created on the master during the bookmark creation process.
- Keep the Archive Attribute on the Replica: A new property added to the Replication properties. If set to on, it retains the archive attribute on the replica during synchronization if master and replica files are identical.
- Retain Local Account Name: A new property added to the Replication properties to retain the local name in the replica machine. Before you run a scenario, manually create the same local users or groups in both Master and Replica. Use this property for workgroup environments. This property is only applicable to Windows machines.
- DNS Redirection using the Update DNS Tool: Use this tool to change the DNS A record of the master server to resolve to the IP address of the replica. You use this tool after you start or stop the VM using the Start/Stop VM feature. You can use this tool by running the update_dns.exe file in the RHA engine installation folder.
- Offline Synchronization Support for Full System Scenarios: The offline synchronization is now extended to full system scenarios including forward, backward, and bare metal restore scenarios.
