What is a SAN? Why a SAN? SAN Fabric Disk Utilization and Centralization Virtualization and Manageability Backup and Restore High Availability Features: Snapshots, Replication Topics

What is a SAN? A storage area network (SAN) is a high-speed special-purpose network (or sub-network) that interconnects different kinds of data storage devices with associated data servers on behalf of a larger network of users. A storage area network (SAN) is a high-speed special-purpose network (or sub-network) that interconnects different kinds of data storage devices with associated data servers on behalf of a larger network of users.

VirtualizationVirtualization Increase disk performance by spreading data across all disks in virtual pool Eliminate load balancing procedures for application and Data Base Virtual Volume Workload is evenly distributed across all spindles in group Moderate Redundant Volume (RAID 5) No Redundant Volume (RAID 0) High Redundant Volume (RAID 1) Today’s RAID Sets SCSI Bus 1 SCSI Bus 2 SCSI Bus 3 SCSI Bus 4 SCSI Bus 5 SCSI Bus 6 RAID 0 Volume RAID 5 Volume RAID 1 Volume

Dynamic pool capacity changes Pool capacity can be expanded by spindle(s) Virtual Disk blocks are automatically relocated to level spindle use Disk Spindles Becoming a Throughput Bottleneck No Additional Storage Space Available Disks Running at Optimum Throughput (dynamic load balancing) Additional Storage Space Available = Available Storage Space Moderate Redundant Volume (RAID V5) No Redundant Volume (RAID V0) High Redundant Volume (RAID V1) + Add More Disks Moderate Redundant Volume (RAID V5) No Redundant Volume (RAID V0) High Redundant Volume (RAID V1) Virtual Storage Pools
