The Software-Defined Data Center Steps Closer to Reality: Policy Controlled Storage-VM Alignment with VVOLs Support

We're very proud to be showcasing the newly unveiled DataSphere data virtualization platform at VMworld this week. The liberation of data from the physical confines of underlying storage complements server virtualization so that compute and data can finally be managed in a fluid manner to address changing business needs. This breakthrough has significant implications for VMware environments.
DataSphere allows various third party storage to be VMware VVOL-aware, making it faster, easier, and more cost effective for enterprises to implement VVOLs in VMware vSphere 6.0. By allowing existing storage arrays to be VVOL-aware, customers can implement VVOLs without purchasing new storage arrays that are VVOL certified. This reduces the cost and complexity to upgrade to VMware vSphere 6.0, the industry-leading virtualization solution. The DataSphere platform also works with newer storage arrays that are VVOL-certified. With more applications being virtualized and the time to market and customer-experience being less forgiving, the need for IT to be agile is more important than ever.
With server virtualization, customers have been able to achieve agility in deploying applications and servers. However, application / server agility without data is meaningless. Data, unfortunately, has been trapped in proprietary storage silos, making storage the most stagnant and inflexible part of the virtualization stack. The ability to dynamically align storage to the changing needs of the applications is the pinnacle of software-defined storage, which can now be accomplished with DataSphere.
DataSphere delivers on the long awaited promise of a software-defined data center with three simple approaches:
DataSphere’s objective-based policy engine allows customers to manage the data with objectives specifically aligned to the objectives of business. These objectives define detailed requirements across performance, latency, costs, protection, and availability. The policies can be applied from an application level, directory level, folder level, and even file level. Rather than the generic / arbitrary designation of “Gold”, “Silver”, “Bronze”, DataSphere’s policy engine allow customers to define specific levels of IOPS, ms of latency, $/GB, # of copies, and X9’s of availability associated with each application, VM, VMDK or file. These objectives are then matched with the capabilities of the underlying storage within vSphere.
Once the objectives and policies are defined, DataSphere ensures that objectives are always met by ensuring placement of VMs/VMDK’s on the tier/array/location specified by the policy. As objectives change, DataSphere triggers dynamic data mobility through data virtualization to match data demands with storage supply across a single global dataspace.
Now, servers, and clients gain the ability to transparently access data while it is intelligently migrated between flash, SANs, NAS, private, and public clouds. This delivers breakthrough agility that enables IT teams to instantly respond to new and changing Service Level Objectives (SLOs) without compromising on performance, cost, or complexity. The combination of VMware VVOLs + DataSphere allows virtual disks (VMDKs) to be moved transparently and non-disruptively across storage tiers through so that businesses can quickly respond to changing workloads and requirements without costly storage over-provisioning.
With Primary Data, virtualized datastores can also seamlessly scale up in capacity and performance without disrupting VMs, allowing companies to add resources at the same rate of their growth without any downtime. By integrating with VMware vCenter through a single datastore, storage management is significantly simplified, and with automated, policy-based data mobility provided by DataSphere, VMs can be placed on the lowest cost storage that meets VM service level objectives (SLOs).
We are showcasing DataSphere at the VMworld 2015 trade show in San Francisco this week and invite you to visit Primary Data booth 805 to see live demonstrations and discuss how you can move beyond managing storage silos and instead manage your data.
