3. Meeting the Availability Challenge

4. Availability Challenges Downtime has a cost both to the business and to you How much does downtime cost you? Needs Reduce downtime to a minimum Downtime

5. Availability Challenges Data lost in outages adds to cost of downtime Lost revenue and lost productivity to recreate data Needs Failover to the latest valid version of data Intelligently protect the data of critical business applications Data Loss

6. Availability Challenges Distance amplifies the challenges of Availability Non-IT personnel responsible for backups Less bandwidth available for network backups Remote data is no less important; same compliance requirements Needs Protect data at remote offices Protect data off-site for disaster recovery Maximize use of existing bandwidth Manage remote protection and DR centrally Geographic Distance

7. Availability Challenges Roughly 50% of workloads are virtualised now “Splitting” of the datacenter into two distinct environments creates challenges Management of two environments Less flexibility with each Needs Unify availability of both environments Leverage virtualisation to improve availability of even physical servers Ease the migration to a fully virtual environment Virtualization

8. Many Challenges – One Solution Virtualization Downtime Data Loss Geographic Distance Real-time Replication Minimize data loss and downtime Replicate over existing WAN bandwidth Virtualized Failover Protect vSphere or Hyper-V environments with host-level management and real-time replication Failover P2V, V2P, P2P, or V2V Application Protection Cluster Integration Replicate from clusters to standalone servers or clusters Create “Stretch Clusters” using the GeoCluster feature

9. Availability Challenges Replication One word Few meanings Many interpretations What replication do you need?

10. Availability Challenges Replication What replication do you need? folder local snapshot near-term system Near-continuous file real-time application byte Time synchronous off-site software asynchronous block storage transactional queue

11. Double-Take Availability Virtual recovery assistant VRA lets you protect a source physical or virtual machine to a virtual target machine running on either Microsoft Windows Server 2008 with Hyper-V or VMware ESX Server. Data is replicated directly into the virtual machine’s virtual disk, which means that the target virtual machine can remain powered off until failover. Automatic failover can be configured if the source/target connection is lost. VRA provisions the target virtual machine for you. It can monitor the protected source machine. During protection setup, VRA lets you increase the drive size, memory, and number of processors on the target virtual machine 11

15. Double-Take Availability Virtual recovery assistant Console can use a Virtual Center or work directly with an ESX server Console collects all information about connection from user prior to executing anything. Able to change amount of RAM, number of processors, and disk sizes of virtual source ESX server configuration (network, stores, etc.) is left to the user. Once started, a DTVRA job is just like any Double-Take job. Any Double-Take client can control the job. Once source is failed-over, Double-Take has no further interaction with the new virtual server.

16. Meeting the Migration Challenge

17. Double-Take Move is … Effortless no downtime X2X Windows server and data migrations. Enables IT Managers and Administrators to consolidate data centers across the WAN, virtualize their physical hardware (P2V), create consistent virtual environments (V2V), refresh physical servers (P2P), all while allowing users to remain productive and working during the migration. Effortless no downtime server and data migrations. Effortless no downtime server and data migrations.

19. You don’t want to buy special hardware.

20. You want to use the network that is already in place.
