Business Continuity and Availability

  5. The Value of iSCSI SAN Architecture • Installation and Management • Build dedicated GigE Subnet • Load iSCSI Initiator on Server • Install/Configure Network Storage Modules • Install Centralized Management Console • Mount and format volumes

  6. 5 features with every LeftHand SAN

  7. Typical Storage Array Architecture Scale-up Storage • Monolithic Array • Not scalable • Controller head Becomes bottleneck • Scales capacity only • Single point of failure • Forklift upgrades

  8. SAN/iQ Storage ClusteringTrue clustering brings reliability, performance, and ease of management Storage clustering Aggregates critical components Data is load balanced Predictable scalability Grow on your terms Scale-out storage Non-disruptive Throttle bandwidth Storage tiering Optimized for type of data Online volume migration Simple centralized management One step server-volume mapping Integrated performance management Storage Node SAS CPU NICs Disk Cache Hardware RAID SAN/iQ Storage Software Redundant Cooling Redundant power SATA Centralized Management Console

  9. High Availability: Need is Greater With Server Virtualization • Application server consolidation onto fewer physical servers exposes users to more application downtime in event of a hardware failure. • Storage consolidation also creates a single point of failure! Traditional Servers Virtualized Servers One server failure, ALL applications goes down One server failure, one application goes down

  10. Network Storage Modules

  11. Full Featured Virtual SAN SAN/iQ within an ESX virtual machine Virtualizes an ESX server’s internal disk resources Significant storage footprint (up to 10TB) Only SAN appliance on VMware SAN/Storage HCL Highly Available storage across multiple ESX systems Shared storage for VMs VSA VSA VSA Virtual SAN Appliance for VMwareESXHigh Availability for Server & Storage For Remote/Branch Offices

  13. Live Demonstration

  14. SAN/iQNetwork RAID RAID 50 and RAID 100 - A combination of RAID 5 or 10 and RAID 0, where data is protected at the drive level with Raid 5 or 10 to provide for recoverability due to a disk drive failure, and the Data Volume (LUN) is then striped or spanned across the RAID set with no additional protection (RAID 0). RAID 5+ RAID 0 = RAID50 RAID 10+ RAID 0 = RAID100 Loss of an NSM within the cluster However With RAID 50 or 100 the loss of an entire unit would result in the loss of the volume since a portion of the data would be lost that comprises the volume. This could result in the server or application going down. This is actually the highest level of protection that some of our competitors offer (either within a single enclosure across multiple RAID 5/10 sets, or spanned across multiple units configured with RAID5/10. Our Network Raid Technology over comes this limitation With RAID 50 a drive in 1 or more units could fail and the volume would still be available. With RAID 100 2 drives in 1 or more units could fail and the volume would still be available. A B Volume 1 C RAID 50/100 Application Server

  15. SAN/iQNetwork RAID Network RAID (across Cluster Protection) SAN/iQ Network RAID stripes and mirrors multiple copies of data across the storage modules in a cluster, completely eliminating any single point of failure. Network RAID is specified on a per volume basis and can be used in conjunction with RAID 0 for performance, and RAID 5 or 10 for added protection and reduced rebuild times Replication level None (0), 2, or 3 Example In this example Volume 1 is striped across 5 individual NSM’s configured with Raid 5 disk protection Replication level = 2 BENEFITS Load Balancing Single drive loss protection in each NSM (from RAID5) Multiple (alternate) NSM loss protection in the cluster (From Network RAID) 10 GigE connection points to Volume 1 Highly redundant, fault tolerant system Enable spread of data over a dynamic # of spindles Loss of an entire NSM within the cluster Data access speeds remain constant No parity calculation required No interruption of application access to data Can Sustain Loss of multiple NSM’s D A A A B Volume 1 B B C C C D SAN/iQ Network RAID level 2 Application Servers
