❷ Storage Capacity Wastage• Over-provisioning to ensure performance• Thick VMDK vs. Linked Clones

❸ Inefficient Storage Management• LUN-based, Not VM-optimized• Compromised snapshots & clones• Slow, complex provisioning

WHAT IT IS❶ New Virtual Storage Approach

Virtual Machine-centric 100% softwareVirtual Storage Appliance (VSA)

❷ New Virtual Storage ObjectAlways high performance (QoS)Always thin provisionedMassively scalable snapshots & clones

❸ New Storage EconomicsMulti-hypervisorAny heterogeneous block-level storageCommodity hardware, high end featuresSupport for Cloud-scale deployments

WHAT IT DOES❶ Boosts Performance up to 10x

Unique I/O system optimized for VM cloudsSpeeds installed legacy storageAccelerates SSD

❷ Up to 90% Better UtilizationThin provisioning without compromisesUnlimited space efficient snaps & clones2-3x greater server VM density2-3x storage efficiency

❸ Efficient Storage Management Manage VMs, not LUNsSeamlessly integrated in VM workflowVM admin provisions storageUp to 10,000x faster provisioning

Defining the Virsto Storage Hypervisor

7

The Emergence of the Storage Hypervisor

“A storage hypervisor [lets] the server […] hypervisor run an increasingly larger portion of the storage services.”

“This may even have bigger potential than the virtual server revolution.”

“Only once it is possible to easily add commodity hardware to storage pools, which are then controlled by virtualization and cloud automation software and subject to user self-provisioning, will we have achieved true virtualization.”

“It makes sense—both operational and financial—to complete the abstraction; to separate the storage functionality from the physical storage system by creating a storage hypervisor.”

Key Trends in Virtualization & Storage

10

Datacenter convergence reinvents datacenter roles

The emergence of SSD (and how to best leverage it)

The hypervisor will extend to effectively manage enterprise storage hardware 

Multi-hypervisor becomes the industry standard

New storage architectures designed for cloud-scale computing and commodity economics will emerge

Increasing adoption of Private, Hybrid & Public Cloud initiatives

The Storage Hypervisor plays a pivotal role in each of these trends
