VMware Design Partner for Caching Solution Brings Host-Based Flash Acceleration to vSphere 6 Ecosystem

SAN FRANCISCO— VMworld 2015 U.S. — August 31, 2015 – SanDisk Corporation (NASDAQ: SNDK), a global leader in flash storage solutions, today announced FlashSoft® software for VMware vSphere® 6 as a virtual data service through integration with VMware vSphere APIs for IO Filtering (VAIO). This latest version of FlashSoft software represents a significant advance in terms of platform integration, usability and performance, increasing customer peace of mind and confidence in host-level storage acceleration. The new VAIO-integrated FlashSoft software will provide write-back caching support for all VMware datastores including VMware Virtual Machine File System (VMFS), Network File System (NFS), VMware vSphere Virtual Volumes™ and VMware Virtual SAN™.

“We are excited about this significant leap forward for our FlashSoft software for VMware vSphere, which will significantly reduce the storage latency that constrains application performance in virtualized servers,” said Sumit Sadana, executive vice president, chief strategy officer and GM of enterprise solutions, SanDisk. “We have been collaborating closely with VMware for more than a year in order to seamlessly bring the benefits of server-tier flash acceleration to the VMware vSphere platform and ecosystem.”

The VMware vSphere APIs for IO Filtering will enable integration of third-party data services with vSphere, allowing partner technologies to contribute to VMware’s software-defined storage capabilities through Storage Policy Based Management (SPBM). As the design partner for caching solutions built on VMware vSphere APIs for IO Filtering, SanDisk collaborated with VMware in the specification and development of this new capability to bring partner technologies into close alignment with vSphere.

The benefits of this new version of FlashSoft for VMware vSphere will include:

  • Usability & Management: As a data service integrated through VMware Storage Policy Based Management (SPBM), the cache will be automatically deployed, managed and maintained cluster-wide through VMware vCenter™ storage policies.
  • Customer Confidence: As a supported solution of both VMware vSphere Storage Policy Based Management and VMware vSphere APIs for IO Filtering, customers and OEM partners will be able to adopt FlashSoft or other third-party virtual data services with the assurance of compatibility and supportability.
  • Increased Performance: The VMware vSphere APIs for IO Filtering framework reduces storage stack latency, delivering data to the solid-state caching filter in one microsecond.

“VMware vSphere APIs for IO Filtering will bring third-party data services into the closest possible level of integration with VMware vSphere,” said Charles Fan, senior vice president and general manager, Storage Business Unit, VMware. “As a design partner, SanDisk has helped us develop a framework for not only incorporating its own FlashSoft software, but also enabling storage acceleration data services for our entire partner ecosystem. This helped us further extend our software-defined storage vision through unique software-based data services."

Significant end user benefits of the newest version of FlashSoft software for VMware vSphere will include:

  • Manageability: Individual virtual disks can be accelerated with ease, so administrators can focus cache resources on the most business-critical data and operations.
  • Write-Back Caching: Support for write-back as well as write-through caching increases data write performance with high availability.
  • Compatibility :Integration through the VMware vSphere APIs for IO Filtering framework enables compatibility with other VMware partner data services, such as replication.
  • Versatility: Performance for virtual disks on all types of datastores can be accelerated, including VMware Virtual Machine File System (VMFS) on SAN, NFS on NAS, VMware vSphere Virtual Volumes on array, DAS and cloud, as well as VMware Virtual SAN.
  • Stability: User-world cache integration reduces the risk that a problem with one virtual machine could impact others on the same host server.
  • Storage Traffic Offload Reporting (STOR): Moving storage traffic to host-level solid-state devices reduces overhead on storage systems, extending their useful life and delivering performance without costly upgrades to storage infrastructure.

“Over the years we have observed many different strategies to bring the performance benefits of flash storage to virtual computing infrastructures,” said Jeff Byrne, Senior Analyst at Taneja Group. "We are excited to see VMware enabling the integration of third-party solutions for solid-state acceleration into the VMware vSphere platform, which will provide customers with greater choice for improving storage performance in software-defined storage environments."

FlashSoft software for VMware vSphere 5.1 and 5.5 is a VMware Partner Verified and Supported Product (PVSP), and is available today. The new FlashSoft software for VMware vSphere 6 is certified VMware Ready™ and will be available for purchase from SanDisk and its enterprise channel partners later this year.
