Introduction to SAN Storage Presentation
Topics What is a SAN? Why a SAN? SAN Fabric Disk Utilization and Centralization Virtualization and Manageability Backup and Restore High Availability Features: Snapshots, Replication
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.
What problems can be solved with a SAN? n Customer requirements n n n n Need more performance Need to control exploding storage Caught in the “MORE” trap - more servers instead of more storage Want better disk utilization Want to centrally manage storage Want server/storage consolidation Have shrinking backup windows Want to reduce the risk of downtime 99% Full 50% Full 1% Full

Improve Storage Utilization Through Storage Consolidation Post-SAN Pre-SAN 50% n Server attached n >50% of storage may be 80% 50% unused to allow for storage expansion (white space) SAN-attached storage n Need only 20% white space for storage expansion n Enable just-in-time storage provisioning n Combine UNIX and Windows storage growth needs n “Get more out of your storage”

Virtualization Increase disk performance by spreading data across all disks in virtual pool l Eliminate load balancing procedures for application and Data Base l SCSI Bus 1 Today’s RAID Sets SCSI Bus 2 SCSI Bus 3 SCSI Bus 5 SCSI Bus 6 RAID 5 Volume RAID 0 Volume Virtual Volume SCSI Bus 4 RAID 1 Volume Moderate Redundant Volume (RAID 5) No Redundant Volume (RAID 0) High Redundant Volume (RAID 1) Workload is evenly distributed across all spindles in group
Virtual Storage Pools l Dynamic pool capacity changes l Pool capacity can be expanded by spindle(s) l Virtual Disk blocks are automatically relocated to level spindle use • Disk Spindles Becoming a Throughput Bottleneck • No Additional Storage Space Available + = Moderate Redundant Volume (RAID V 5) No Redundant Volume (RAID V 0) High Redundant Volume (RAID V 1) Add More Disks • Disks Running at Optimum Throughput (dynamic load balancing) • Additional Storage Space Available Storage Space Moderate Redundant Volume (RAID V 5) No Redundant Volume (RAID V 0) High Redundant Volume (RAID V 1)
Improve Availability of Enterprise Information (via SAN-based Backup/Restore) Pre-SAN Post-SAN LAN NT Backup Server LAN NT SANs enable backups quicker than network-based or Direct-Attached n Enterprise applications back in service quicker n Reduced unscheduled downtime to restore lost or corrupted data n Improves Enterprise Productivity n n Backup traffic clogs corporate Backup Server LAN n Backup/Restore time is lengthy n Application and information not available during backup/restore Availability of information keeps your business running
High Availability and Disaster Recovery: Snaps, Clones, and Replication n Instantly creates point-in-time copies of data for business continuance n Provides instant, automated restore of a source volume n Enables application and database integration for backup, recovery and other uses n Array based replication Production Volume Snapclone or Vsnap (1) 7 2 6 3 5 Open Systems Fibre Channel 4 Open Systems Fibre Channel
Review of SAN Benefits Performance • • Fibre Channel disks and connectivity Data shared across all disks Availability • • Dual path/no single point of failure for mission critical servers Traditional RAID configurations, dual ported hard drives, hard drive sparing Scalability • • Dynamically grow server storage increasing control and flexibility for future growth Increase disk utilization and consolidate servers through virtualization Manageability • Reduce administration costs and manageability by virtualizing disk Backup, Restore, and Disaster Recovery • • Solve backup/restore problems through SAN based backup Limit backup window issues Limit risk of lost data through snaps and clones Array based Replication Heterogeneous connectivity • Consolidate storage regardless of operating system
