Benefits of Server and Storage Consolidation
Simplifies management – Centralize storage management– Improve service levels
Increases flexibility– Optimize capacity planning– Eliminate scheduled downtime
Reduces total cost of ownership– Improve capacity utilization – Require fewer high-powered systems
Enables high-speed, nondisruptive server workload movement
– Migration (VMware VMotion)– Failover (high availability)– Load balancing (VMware DRS—
Distributed Resource Scheduler)

Celerra: No-Compromise Availabilityfor Virtualized IT Environments
Server virtualization provides resource resiliency and resource flexibility
Benefits of server virtualization realized with highest availability storage
– Advanced N+1 clustering N+1 means no performance
degradation after failover
– Controller-based RAID Consistent, predictable performance
during RAID events
– Independent management Independent management station notifies
and manages any failure events
Five 9s Availability

Celerra Replication and VMware
Guest operating system images and the application data can be replicated
Application-consistent replication– Fibre Channel or iSCSI– Local or remote replicas– Integration with EMC Replication Manager
Celerra SnapSure and Celerra Replicator for NFS– Replication granularity is entire NFS volume

Celerra Virtual Provisioning
Capacity oversubscription– File systems– iSCSI LUNs– Logical size greater than physical
size
Physical allocation in real time to logical size

Celerra Virtual Provisioning and VMware—Maximize Storage Utilization
With Virtual Provisioning enabled– Additional storage allocated only when needed– File system automatically extends when its utilization raises– Virtual machines are presented with upper-size storage limit
In this model– No need to over-provision– Unallocated space can be utilized across the virtual data center
