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

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

• Limited flexibility in moving virtual machines as volumes are mounted to the parent

• Best performance (least Hyper-V overhead)

LUN 3

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
