5. 5 SANmelody Application Support Services Simplified Centralized Windows Volume Administration – Eliminate Steps Make your administration more Productive! Central vs. distributed Windows volume administration Create, manage and map Windows file systems Windows Disk Manager used to create FAT or NTFS file systems Managed directly by SANmelody Map file system volumes to application servers Consolidation of disk resources – Greater Flexibility Migrate disparate Direct Attached Storage (DAS) disk hardware off of independent Windows Application servers and workstations to a centralized location managed by SANmelody Network services. Disks can continue to be used as is (mapped back to the owning application server) or re-purposed and re- configured into Virtual Capacity pools of available storage that will provide more effective use of the disk resources and provide wider use and access to these resources.

7. 7 SANmelody Application Support Services Supports Immediate use and access of pre-existing Volume data – Save time Mount existing Windows data volumes Consolidate external direct attached storage (DAS) that is currently connected to individual servers and workstations Accelerate I/O performance of pre-existing data volumes and deliver to owning Windows Application Servers and Workstations over existing Ethernet NICs (iSCSI) or Fibre Channel Introduces the benefits of SAN technology and storage virtualization Improve data redundancy Create high availability Migrate data to newer, faster or lower cost storage Increase storage performance All with one (1) reboot of servers and workstations SANmelody provides the ability to manage and immediately utilize ("As is" ) formatted (NTFS/FAT) Windows volumes. Being able to utilize formatted volumes (NTFS or FAT) allows the user the immediate use of pre- existing data that resides on the file system of that volume.

18. 18 SANmelody Application Support Services Non-disruptive use of SANmelody features – Power up all your disks! Easy to apply SANmelody features (performance and function) to volumes. Volume performance is improved by SANmelodys built-in cache acceleration. The volume can be delivered (mapped) to Application servers over the FC or IP infrastructure. Synchronous mirrors can be configured so that the data is mirrored to a SANmelody partner in a high availability configuration. This provides continuous access to the data in case a failure occurs to the data volume. The Snapshot features can be used to generate a point-in-time snapshot of the data volume. Then other applications can utilize the point-in-time version for offline work. Asynchronous IP Mirrors can be used to transmit the volume to a remote site for disaster recovery or other remote site uses. All features can be utilized non-disruptively in real time as the volume is being utilized by the owning application servers. The administrator has the choice of "in the SAN or out" when required - no lock in, freedom to gain enhancements when needed.

19. 19 Real Utility and Network Storage Services Now, Disk Servers have enabled storage to become a utility function in much the same way as a print or file server. "This approach to growing disk capacity makes real sense, but has never been possible before. Now, Disk Servers have enabled storage to become a utility function in much the same way as a print or file server. – IT Director, Warwick University SANmelody makes it possible to serve up high-performance and highly available storage. - CIO, Wasatch Advisors
