7. Hidden Storage Costs of Virtualization
Storage Architecture: not virtualization ready
Degraded Performance
VM
• Random I/O degrades VM performance
• Ease of VM creation increases server workloads
VM
Storage Capacity Wastage
• Over-provisioning to ensure performance
VM • Thick VMDK vs. Linked Clones
Inefficient Storage Management
VM
• LUN-based, Not VM-optimized
• Compromised snapshots & clones
• Slow, complex provisioning
Virtualized Servers & VMs Writes to Storage Array

8. Defining the Virsto Storage Hypervisor
WHAT IT IS WHAT IT DOES
New Virtual Storage Approach Boosts Performance up to 10x
Virtual Machine-centric Unique I/O system optimized for VM clouds
100% software Speeds installed legacy storage
Virtual Storage Appliance (VSA) Accelerates SSD
New Virtual Storage Object Up to 90% Better Utilization
Always high performance (QoS) Thin provisioning without compromises
Always thin provisioned Unlimited space efficient snaps & clones
Massively scalable snapshots & clones 2-3x greater server VM density
2-3x storage efficiency
New Storage Economics Efficient Storage Management
Multi-hypervisor Manage VMs, not LUNs
Any heterogeneous block-level storage Seamlessly integrated in VM workflow
Commodity hardware, high end features VM admin provisions storage
Support for Cloud-scale deployments Up to 10,000x faster provisioning

9. The Emergence of the Storage Hypervisor
“A storage hypervisor [lets] the server […] hypervisor run an
increasingly larger portion of the storage services.”
“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.”
“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.”

10. Key Trends in Virtualization & Storage
 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
