*Third-party marks and brands are the property of their respective owners. Copyright © Intel Corporation 2004 Volume Management & Dynamic Volume Expansion Dynamic Volume Expansion No Server Downtime Users stay online If done Manually, requires File system expansion (Diskpart for example)

*Third-party marks and brands are the property of their respective owners. Copyright © Intel Corporation 2004 Dynamic Volume Expansion Thin Provisioning and Autogrow Volumes can be “Thin Provisioned” (Partition/Device size greater than actual allocated space) Volumes can be set to Autogrow based on user defined thresholds and increments Eliminates the manual file system expansion and admin interaction Partition (Server perceived disk size) Allocated Storage space Auto Grow Incremental storage allocations

*Third-party marks and brands are the property of their respective owners. Copyright © Intel Corporation 2004 Volume 1 Base Snapshot: Manual only Snapshot always same size as primary volume Benefits: Near instantaneous retrieval of data compared to tape backup solutions. Facilitates recovery to pre-error state (compared to mirroring, which would mirror all errors) Good for manual backups and data mining Gives customers without snapshot experience a low risk taste of the technology 1:00 PM2:00 PM Active File System Snapshot 1 Snapshot 2 Rollback Volume: Volume reverts back to the point in time the snapshot was created Base Snapshot

*Third-party marks and brands are the property of their respective owners. Copyright © Intel Corporation 2004 Storage System Management Advanced Features ** Scalability Package Multi-node virtualization which allows a group of SAN systems to act as a single unit Load-balancing / pooling allows for resource sharing between the storage from all SAN systems in the cluster Replication enables data to be split among all systems in a group in redundant and non- redundant configurations Configurable Snapshot Package Ability to automate process of scheduling volume snapshot copies (base software only offers manual snapshot capability) Allows dynamic snapshot sizing to capture only incremental changes between snapshots to optimize disk utilization Remote Data Protection Package Asynchronous remote copy feature that allows for snapshots to be taken between multiple sites (over LAN or WAN) for disaster recovery Client Server Clustering Agent Support for Microsoft* Cluster Server and Veritas* Cluster Server Allows Microsoft* and Veritas* clustered client servers access to shared SAN storage **Based on the Intel® Storage System

Copyright © Intel Corporation 2004 Scalability Package with Load Balancing Volumes (LUN’s) striped across all units within a cluster Consolidates and simplifies management Automatic load-balancing w. “drag & drop” storage Volumes are evenly distributed Over all Spindles Over all Processors Over all Cache Over all Network Connections Provides redundancy and performance

*Third-party marks and brands are the property of their respective owners. Copyright © Intel Corporation 2004 How Replication Works The order in which SSMs are added to the cluster determines the order in which copies of data are written to the volume. Dynamic Pool Pool Member 1 Pool Member 2 Pool Member 3 Pool Member 4 Pool Member 1 Pool Member 2 Pool Member 3 Pool Member 4 Pool Member 1 Pool Member 2 Pool Member 3 Pool Member 4 B1 B2 B3 B4 B1 B2 B3 B1 B2 B3 B4 4 Blocks of Data Replication=1 4 Blocks of Data Replication=2 4 Blocks of Data Replication=3

*Third-party marks and brands are the property of their respective owners. Copyright © Intel Corporation 2004 Volume 1 Snapshot -- a set of incremental pointers of a volume at a point in time. It allows the users to “roll back” the volume to its state at a certain point in time in the past. Features: Can be automated on a per volume basis with retention policies, etc. No limit on the number of Snapshots Can be mounted as Read-Only volumes for backup or single file restore purposes. Benefits: Near instantaneous retrieval of data compared to tape backup solutions. Facilitates recovery to pre-error state (compared to mirroring, which would mirror all errors) Minimal storage space required by incremental pointers to only delta (change) blocks. Some competitors require large “set aside” storage to be pre-allocated for snapshots. LeftHand allows Snapshots to start small and “Autogrow” as needed. 1:00 PM 2:00 PM Active File System Snapshot 1(preserves original file system volume) Snapshot 2 Rollback Volume: Volume reverts back to the point in time the snapshot was created Volume 1 Stores changed blocks only Configurable Snapshot Package

*Third-party marks and brands are the property of their respective owners. Copyright © Intel Corporation 2004  Volume/snapshot relationship can be conceptually thought of as “layers”  Space is allocated from the storage pool to accommodate snapshots  User_Data_ss1 is the base line snapshot, the volume is read only  User_Data_ss2 contains the deltas since User_Data_ss1 was created  User_Data contains the deltas since User_Data_ss2 was created.  The User_Data volume is comprised of User_Data + User_Data_ss2 + User_Data_ss1 User_Data User_Data_ss1 User_Data_ss2 Snapshot – Layered Architecture

*Third-party marks and brands are the property of their respective owners. Copyright © Intel Corporation 2004 Remote Data Protection Package – “Killer App”  No distance limitations with IP protocol  Affordable due to Ethernet underpinnings  Can be managed from one location  Easy off-site backup management, either real-time or via snapshot  Remote Data Protection replicates at the block level – Efficient for whole volume replication  Remote Data Protection replicates incrementally – After the baseline level snapshot, future snapshot layers to be copied only contain incremental data.  Remote Data Protection is efficient in dealing with network glitches – Copy is done in10% increments. If the network failed in the middle of a large volume copy, the resumed copy will start at the closest 10% mark.  Remote Data Protection can be used to create “in Place” copies of volumes – Can be used to facilitate development, testing, or Data Mining efforts  Remote Data Protection supports multiple sites replicated to a central site – Can be used to facilitate centralized backup  Remote Data Protection can replicate bi-directionally between 2 sites. Allows for a company with multiple locations to provide Disaster Recovery for each site Site A Site B Remote Data Protection provides cost-efficient site diversity

*Third-party marks and brands are the property of their respective owners. Copyright © Intel Corporation 2004 Volume 1Snapshot 1 Secondary Snapshot 1 Secondary Volume 1 When a user manually chooses to create a Remote IP Copy or initiates a schedule to do so, the system goes through the following 4 step process… 1.System takes a snapshot of the Primary volume 2. System creates a secondary volume and an empty snapshot of the backup volume 3. System copies data from the primary snapshot to the Remote IP Copy snapshot Production Site cluster Remote or DR Site cluster Wan or Internet Link Snapshot 2 Secondary Snapshot 2 4. When a schedule is present, subsequent Snapshot layers are created and replicated to the remote site to “catch up” the Volume In the Case of a disaster, one of the Secondary Snapshots can be “rolled back into the Secondary Volume and then put into production Disaster!!!
