  1. AssuredRemoteRemote Replication

  2. AssuredRemote Key Messaging human error 32% Snapshot / Volume Copy computer virus software program malfunction 7% 14% Replication site disaster 3% 44% RAID 0,1,3,5,6,10,50 hardware or system malfunction Dot Hill Confidential 2 • Completes the Picture for Dot Hill Data Protection • Introduces new technologies • Remote Data Replication • Disaster Recovery • Centralized Backup • Enhances Existing Features • Higher snapshot count • Enables regulatory Compliance • HIPPA, Sarbanes-Oxley • Provides Investment Security • Customers can purchase technology when needed • Offers cost saving options • Heterogeneous Storage Environments – lower cost SATA at remote facility • Drive-Spin-Down implementation reduces operating cost at both primary and remote sites • Array-Level replication for entry-level customers off-loads operation from critical application servers

  3. AssuredRemote Value Propositions Why, current or potential re-seller partner, you want to sell this product… i.e., the 30-second elevator pitch • Increase revenue and margin opportunity with an expanded product portfolio of software and hardware products, to solve disaster recovery and centralized backup problems. • Ensure on-going business viability by protecting data against local area and wide area disasters. • Simplify operations and reduce operating expenses by creating a common and centralized backup infrastructure and strategy for remote operations and branch offices.

  4. AssuredRemote Feature/Function Release 1 Content; Target GA 2Q09

  5. Simple Replication Creation 1. Choose volume 2. Select target 3. Specify name 4. Select link type 0. You defined target system 5. Specify if also do first replication immediately. Of later you will do so 6. Name it and apply 5 Dot Hill CONFIDENTIAL

  6. Peer sites with failover Supported by T100 Hybrid Controller Hybrid Controller • Pros: Remote DR for Local disaster of servers and storage; Local infrastructure for online access • Cons: Slow replication over WAN; Have to build excess capacity into each site • Data Restore Modes: Replicate back over WAN, Sneaker Net • Failover Modes: VMWare, Hyper V fail over to Remote Servers via manual moves

  7. Remote Site Data Protection Supported by T100 Hybrid Controller Hybrid Controller • Pros: Remote DR for Local disaster; • Cons: No protection for Local Servers; More expensive than Tape (maybe use single controller iSCSI in branch) • Data Restore Modes: Replicate back over WAN, Sneaker Net, replace Array

  9. Replication Technologies Protection Against Local and Wide-area Disasters • Snapshot Replication • System copies snapshot data from the primary to remote site • Synchronous Replication • I/O for I/O replication to the remote system • Prior to application server getting write acknowledgement back it must be committed to remote system (Server – Storage – Remote Storage – Server) • Semi-Synchronous Replication • Nearly I/O for I/O replication • Once I/O committed to local storage and server is acknowledged, then I/O sent to remote system (Server – Storage – Server – Remote Storage) • Asynchronous Replication • Store-and-Forward replication • Write I/Os propagated to remote volume • Time interval • Amount changed • % changed

  10. Array Based Primary Site Secondary Site • Storage array to Storage array • Storage communicates directly with servers • Difficult to automate failover/failback operations

  11. Host Processing Primary Site Secondary Site Replication Software • Host systems manage replication tasks • Storage communicates directly with servers • Easier to automate/manage failover/failback operations

  12. Appliance - In Band Secondary Site Primary Site Storage Server Storage Server • In-band storage system manages replication tasks • Storage communicates with In-Band storage server which communicates with application servers • Easier to automate/manage failover/failback operations

  13. Appliance - Out of Band Primary Site Secondary Site Agent • Out-of-Band storage system manages replication tasks • Storage communicates with application servers • Easier to automate/manage failover/failback operations
