DESCRIPTION
The concept of the software-defined datacenter (SDD) is gaining recognition, as IT moves away from infrastructure traditionally defined by hardware toward a more flexible infrastructure built around software and dynamic allocation of resources. In the SDD, all virtualized storage, server, networking and security resources required by an application can be defined by software and provisioned automatically. Virsto’s VM-centric storage hypervisor is purpose built to deliver software-defined storage: the missing link for storage agility, performance and efficiency to realize more agile IT.

The missing link for the Software Defined Datacenter
Gregg Holzrichter, VP Marketing
VMware’s Software Defined Datacenter Vision

The foundation for cloud computing. Intelligent software that abstracts out hardware resources, pools it into aggregate capacity, enabling automation to efficiently dole it out as needed by applications.

❷ Storage Performance & Capacity Optimization
❸ Increases Agility & Workflow Optimization
❶ Purpose built storage software for VMs that aggregates capacity, enabling automation to efficiently dole it out as needed by applications
WHAT IT DOES
Virsto for vSphere 1.5 Release
6
Transparent Integration into familiar VM workflows No additional GUI / Management Console to learn
Virsto vDisk software storage object reduces spindle count/storage costs
Cuts VM provisioning times by 75%
Seamless integration with leading VDI solutions Rapid Deployment Wizards support VMware View 5, XenDesktop 5
Other Virsto for vSphere 1.5 Features
7
Support for up to 10,000+ vDisks per vCenter Server Delivers “linked clone” scalability not available in View Composer
Greater than 8 VMware cluster nodes
VDI Deployment Enhancements Guaranteed delivery of requested # of desktops without manual recovery
Zero Down Time Migration to Virsto Storage vMotion running VMs into Virsto “format” without downtime
Source storage becomes “thin” during import process to save space
Seamless Integration with VMware View
Virsto Deploy Wizard supports View
On VMware ESX/ESXi 4.1 or ESXi 5.0
Transparently embedded into standard desktop creation workflows
Effectively replaces View Composer
Supports the standard deployment, re-deployment and refresh workflows
Native integration - Virsto View Connector hands Virsto-provisioned desktops over to View Manager without a separate control interface.
8
Virsto for vSphere 2.0 Features Integrates with VAAI/VADP to enable Virsto storage provisioning thru
native VMware wizards
Can now transparently handle all major workflows (VM creation/deletion, storage provisioning,
snapshot backups, etc.) using native vSphere wizards
Scalability enhancements
Unlimited single image management across up to 32 hosts/cluster for improved efficiency,
easier administration
Administrative enhancements
Leverage native security framework (RBAC), improved instrumentation (health, IOPS, etc.),
support for non-disruptive upgrades
