Turbo-charge Your Storage SANsymphony Product Introduction Turbo-charge Your Storage Host SANmelody SANmelody I/O 20 Storage Array Cache controller I/O 250 - 300 As regards quality of service, having DataCore software in front of intelligent shared arrays as well as mid-range and low-end disks actually accelerates their performance. This is a result of a powerful cache multiplier effect, unique to SANsymphony. The additional performance and enhanced channel fan out can be used to share the vital storage resource with more servers. Diverse paths through the networks and N+1 redundant nodes ensure no single point of failure. Disk I/O 4000 – 6000 Copyright 2000 DataCore Software Corporation

SANsymphony Product Introduction Auto-Provisioning 12TB allocated No Agents on Hosts 2TB volume (NVM) assigned to each server Small fraction of real capacity allocated to each virtual disk SANmelody automatically allocates capacity when needed SANmelody Category D adds even more capacity, performance capabilities, high availability and data protection features. The ability to automatically provision storage capacity is a unique feature of SANmelody that will save time, simplify administration and reduce wasted capacity. Finally, we get rid of the guessing. Instead, SANmelody elegantly auto-provisions just enough space, just-in-time to needy servers. It does so in real time by assigning very large “virtual disk images” to each server. By large, we mean the largest addressable disk an operating system can handle (often 2 terabytes). In much the same way that virtual memory operates, all of the servers think they have plenty of room. Physically, however, only a fraction of real space is assigned to the pool. The amount on day one is dictated by current actual requirements plus a reserve for near term growth. Those applications that consume additional capacity as time goes on, deplete the free space, many never reaching anywhere close to their 2 terabyte virtual allotment. SANmelody doles out additional real space in granular increments, say 128 MB and monitors for use before granting more. Over time, as the free space for the entire pool is chewed up, the low reserve mark is reached, triggering a notification. 20% reserve is common. Upon this alert, additional disks are acquired and added non-intrusive to the pool, upping the free space to a comfortable level once again. The servers, and more importantly their users and applications are never interrupted. 1TB Pool Unallocated capacity is available for use by any server No committed storage penalty!

Auto-Provisioning Saves Time and Effort SANsymphony Product Introduction Auto-Provisioning Saves Time and Effort Traditional Disk Provisioning Determine which Application is running out of space Determine how to add storage (extend Volume/LUN, add LUN, etc.) Determine how much storage to add. Determine where to get storage. Allocate storage from Pool. Set protection (LUN masks) for Applications to see correct storage. Set switch zoning and HBA settings if applicable. Add storage to App. LUN or create new App. LUN Note: Typically requires reboots and downtime Perform Volume formatting, Volume Management, Configure OS and Apps. to be able to use the larger LUN or new LUN Replenish Pool (add disks) DataCore Automates the Process Create a virtual volume Drag and Drop the volume on the server channel Apply SANmelody does the rest!

SANsymphony Product Introduction Snap Shot Snapshots Instantaneous Point-in-time snapshots Complete Images Snap from FC to SATA disks Production Volume Snapshot Copy Disk Snapshots Take Place of Daily Backups Disk Servers can be configured to periodically generate daily 'snapshots,' or point-in- time copies, of critical volumes on separate disks -- eliminating the need for daily tape backups. The snapshots may be mounted just like a removable drive to rapidly restore an application to a known good image from the previous day. Where conventional tape backups can disrupt application processing for several hours, an online snapshot only requires a brief application pause to record the current state of the data. Immediately after a snapshot is taken, the 'live' source volume is released and applications may resume updates. SANmelody then captures subsequent changes to the data in real-time on a separate volume. This process dramatically reduces the time to create a "backup copy." Use Auto-Provisioning with Snapshots to conserve capacity Copyright 2000 DataCore Software Corporation

SANsymphony Product Introduction Snapshot View Point-in-time Snapshot (Backups, testing, etc.) Live Volume The magic behind snapshots is in making the backup server believe it is sourcing all the information from a frozen-in-time image. The backup image is really a snapshot “view” concocted by combining unchanged blocks on the live volume with copy-on-write blocks on a separate virtual disk. SANsymphony’s copy-on-write operation preserves the original contents of the live volume prior to updates to maintain the illusion. unchanged updated Online Application copy-on-write (by SANsymphony) Copyright 2000 DataCore Software Corporation

Why go Virtual? What is the driving force to go Virtual? Flexibility to Adapt to Change + Economics and Productivity: Saving Money, Time and Effort Better utilization and consolidation of assets Rapid response to address growth and change Hardware Independence and Cost Savings Productivity gains by consolidating tasks, process and resources Server Virtualization Processor utilization, for example, Intel/AMD typically CPUs averages utilization of less than 10 percent - 90% waste Storage Virtualization On average 25% of allocated physical disk space in Microsoft environments is effectively utilized by users – 75% waste

SANmelody: Target Customers Customers who: Are seeking entry-level SAN capability ($10k-$50k storage budget) Have a limited infrastructure seeking low cost disk solutions are implementing virtual server infrastructures Have a low-cost DR or business continuance requirement Have 3-10+ application servers, 500GB – 5TB+ iSCSi or Fibre Channel storage connectivity

SANsymphony Product Introduction Example Building 1 Building 2 Remote Site This financial company purchased 2 TagmaStor boxes for production. Instead of purchasing a third Tagma to replicate to they moved one of the production boxes to the DR site, added some EVA storage for production and used SANsymphony to replicate. The result was huge saveings and cost avoidance. Copyright 2000 DataCore Software Corporation
