  1. New releases in Q2 2009: SANsymphony™ 7.0 SANmelody™ 3.0 Storage Virtualization SoftwareTechnical Highlights

  2. SANmelody SANsymphony

  3. Major New Features • SANsymphony 7.0 & SANmelody 3.0 now run on Windows Server 2008 (32 & 64-bit) • Up to 1 TB “Mega Caches” per node • Advanced Site Recovery[Separately priced SANsymphony option] • Automatic Space Reclamation for Thin-Provisioned Volumes • Hypervisor migration (P-V-V) [Separately priced “Transporter” option] • Integration with VMware Virtual Center

  4. High-Speed Caching New! Speeds up performance Up to 1 TB Mega Caches per node • Accelerates disk I/O response from existing storage • Uses CPUs and memory from general purpose servers as powerful, inexpensive cache • Anticipates next blocksto be read & groups writes to avoid waiting on disks SANmelody SANsymphony

  5. Turbo-charged Virtual Disk I/O Avg. Response (µS) DataCore L1 Cache <20 Array L2 Cache 250 – 300 Disk Drive 4000 – 6000 Output from Cache Poll for Input CPU CPU High-SpeedLevel 1 Caching Un-cachedArray Pre-fetch WriteCoalesce CPU CachedArray CachedArray CPU Disk Subsystems

  6. Advanced Site Recovery New! Spread DR responsibility across multiple smaller sites • Choose locations best suited to handle specific DR load • Viable with lower speedWAN circuits • Built-in central site restoration • Universal coverage for heterogeneous scenarios • Same automated process for Virtual & Physical systems SANsymphony Optional

  7. Low Cost Alternative: 1-to-Many DR New! DR Site x DR Site y DR Site z RemoteReplication HA • Thin pipes VM VM VM VM VM VM VM VM VM VM Central IT site StorageVirtualization

  9. Appears to computers as very large drives (e.g. 2 TB disks) Takes up only space actually being written to Dynamically allocates more real space when required Reduces need to resize LUNs Thin Provisioning New! Just enough space, just-in-time Space Reclamation SANmelody SANsymphony

  10. Guessing on Allocation Leads to Waste Disk 1 Disk 2 Disk 3 Free Few Blocks Actually Written To Capacity consumed whether used or not!

  11. Waste-Free Thin Provisioning + 2.0TB + 2.0TB + 2.0TB 2TB Virtual Allocation: Free V Disk 3 2TB 6.0TB 0 Free V Disk 2 Actual = 0.4TB 2TB 0 Free V Disk 1 0 Time to add more Physical Disk Pool Expand asNeeded No Device Dependency 0 0.4TB 1TB

  12. New! Thin Provisioning Space Reclamation Recover space from deleted files in virtual volumes 2TB Space previously allocated to deleted file Free V Disk 1 2TB 0 Fill with zeroes Free V Disk 1 0 Release zero-filled space back to free pool 0 Physical Disk Pool

  13. Physical/Virtual to Virtual Disk Migration Quickest way to migrate from one Windows environment to a dissimilar physical or virtual server platforms • Source image rapidly available to destination • No waiting on lengthy disk-to-disk copies; they occur transparently in background • No error-prone conversions • DataCore handles differences with the same ease as any other virtual disks New! SANmelody SANsymphony “Transporter” Option

  14. VD1 Boot Disk Boot Disk VD2 VD4 VD1 VD3 VD Storage Transporter Agent VD1 VD1 New! Rapidly Migrate from Physical to Virtual VirtualizedServer (Destination) • Agent exports disk image • Unique ‘pass-thru’ technology sees, snaps & copies active source disk • Boot copy modified to boot VM • Converted disk mounted by destination as boot or data device VM Snap Copy Transporter VM Physical Server (Source) LAN

  15. Virtual Disk Pooling Consolidate like or unlike disk resources • Split pool into tiers • Create and assign virtual disks of desired sizes • Define access rights • Share them among clients • Expand capacity without downtime • Eliminate stranded space SANmelody™ SANsymphony™ ≤32 TB >> Petabytes

  16. Load Balancing Improve response and throughput • Overcome typical storage-related bottlenecks • Spread load on physical devices using different channels for different virtual disks • Automatically bypassesfailed or offline channels SANmelody SANsymphony

  17. Circumvents drive failures Spreads I/O across multiple spindles Offloads RAID 0 & 1 Supports popular RAID devices in pool RAID Striping Better protection & performance SANmelody SANsymphony

  18. Synchronous Mirroring Real-time I/O replication for High-Availability • Eliminates SAN or storage as a single point of failure when combined with multipath I/O drivers • Enhances survivability using physically separate nodes • Updates two distributed copies simultaneously SANmelody SANsymphony N+1Redundancy Pair

  19. Virtual Disk Migration Transparently move contents from one disk to another • Allows non-disruptive hardware disk upgrades for mirrored volumes • Clears & reclaims space occupied by original SANmelody SANsymphony

  20. Online Snapshots Capture point-in-time images without tying up much disk space or make complete clones • Recover quickly atdisk speeds to known good state • Eliminate back-up window • Provide “live” environment for analysis, development& testing • Keep snapshots in lower tier, thin provisioned storage SANmelody SANsymphony

  21. Continuous Data Protection & Recovery Return to any point-in-time withouttaking explicit backups • Dial back to restore an arbitrary point-in-time • Logs and timestampsall I/Os • No need to quiesce or interrupt applications SANsymphony Optional

  22. Remote Replication Keep distant copies without impacting local performance • Perfect for disaster recovery or business continuity • Only needs a basic IP connection to secondary site • Bi-directional • Asynchronous SANmelody SANsymphony 1-to-Many Many-to-1

  23. SAN-wide Centralized Management Control and monitor all SAN resources from one console • Automates laborious, repetitive tasks • Intuitive to operate • Universal tools work across like or unlike devices • Plug-ins for integration into Hypervisor consoles SANmelody SANsymphony 2 Nodes SAN-wide

  24. Analysis & Reporting Tracks & charts long-term SAN behavior • Reveals SAN resource consumption & performance trends • Assists with capacity planning, utilization & quality of service decisions • Export results to 3rd party tools for further analysis,charge-back & billing SANmelody SANsymphony Optional Optional

  25. Storage Virtualization NON-STOP WASTE-FREE LIGHTNING-FAST
