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

Typical Storage Array Architecture

Monolithic Array• Not scalable

• Controller head Becomes bottleneck

• Scales capacity only• Single point of failure• Forklift upgrades

Scale-up Storage

The LeftHand DifferenceEnterprise class features that are all-inclusive, and effortless to administer

SAN/iQ Storage ClusteringTrue clustering brings reliability, performance, and ease of management

Storage Cluster• Aggregates all components for performance• Data is load balanced across all nodes• Predictable scalability

Grow on Your Terms• Non-disruptive scalability• No forklift upgrades• Scale everything• Throttle Bandwidth

Create Tiers of Storage• Create a tiered environment for different

performance requirements• Online Volume Migration

Simple Centralized Management• Provisioning• Monitoring• Security

SAN/iQ Network RAIDIntegrates Synchronous Replication with Automated Failover and Failback

Beyond Component Redundancy• Protects data from array failure• Synchronous Replication• Configure on a per-volume basis• Change RAID level on-the-fly

High Availability• Multiple disks, controllers, or

arrays• Zero disruption of data access• Ensures “high availability” for

data

Recovery Server

SAN/iQ cluster within ESX• Highly Available storage across

multiple ESX systems• Shared storage for VMs

In the event of an ESX failure:• SAN/iQ keeps volume online• VMware HA will failover VMs

Full Featured Virtual SAN• SAN/iQ within an ESX virtual machine• Virtualizes an ESX server’s internal

disk resources• Significant storage footprint (up to 2TB)• Only SAN appliance on VMware

Matching Virtualization Features

Storage VirtualizationUses enterprise class x86 servers to Virtualize storage clusters

Server VirtualizationUses enterprise class x86 Servers to Virtualize multiple servers

Storage ClusteringData volumes are automatically load balanced and protected across storage clustersCapacity, IOPS, cache, and bandwidth scale linearly and dynamically as needed

VMware DRSContinuously monitors utilization across resource pools and intelligently aligns resourcesCPU, memory, and networks added dynamically as needed

Online Volume Migration Migrate volumes between storage clusters

VMotion Live migration of VMs between ESX Servers
