Server Virtualisatie
Welke knelpunten rondom servers herkent u?
Hoe ervaren we server en storage infrastructuren?
Virtualisatie op alle fronten
Virtual PresentationPresentation layer separate from process
Virtual StorageStorage and backup over the network
Virtual NetworkLocalizing dispersed resources
Virtual MachineOS can be assigned to any desktop or server
Virtual ApplicationsAny application on any computer on-demand
Interface bound to process
Storage assigned to specific locations
Network assigned to specificlocations
Operating System assignedto specific hardware
Applications installed toSpecific hardware and OS
Virtualization is the isolation of one computing resource from the others
Vroeger Nu
Virtualization results in more efficient resource utilizationVirtualization enables greater flexibility and simplified change management

Adopt to server-ization of storage:
Storage Clustering
Scalable performance and capacity
Network RAID
Availability beyond the box
iSCSI NetworkingFlexibility with common infrastructure at affordable cost
Thin ProvisioningReduce costs, increase capacity utilization
Local & Remote CopyEfficient backup and disaster tolerance
2 to 50+ nodes

Centralized Management Console
So, how does this architecture complement server virtualization?
• Grow on your terms− Add new nodes at any time− Automated re-allocation of volumes− Non-disruptive
• Centralized management− One console for all LeftHand storage across
multiple sites− Supports multiple clusters− “Drag and drop” volume management

• The goal for SAN availability is "no nines," or 100% availability. (Gartner,2007)
• Human error and firmware bugs are the weakest links, even in properly deployed SANs. (Gartner, 2007)
iSCSI volumes are automatically restriped as each node is added:• No downtime• No re-planning your SAN• No LUN reconfiguration

Pass Through
• Limited flexibility in moving virtual machines as volumes are mounted to the parent
• Best performance (least Hyper-V overhead)
LUN 3
Hyper-V Server
Parent Child 1 Child 2
E:
• Fully enables SAN-based high availability and load balancing
• VMs can easily be moved from parent to parent
• Recommended for all application specific volumes
• Use thin provisioning for higher utilization per application guidelines
