Sanbolic Enables Virtual Machines in VMware ESX Environments to Share Access to Application Data on SAN Storage Volumes

Share Article

Virtual machines running Windows operating systems on VMware ESX can now share access to application data on SAN volumes and maintain access to application data, even when virtual servers are migrated between physical host servers. Sanbolic's Melio clustered file system addresses a shortcoming of virtualization across all major platforms - an inability to share application data between multiple virtual machines, which creates an inflexible storage platform for virtual data centers.

Virtual machines running Windows operating systems on VMware ESX can now share access to application data on SAN volumes and maintain access to application data, even when virtual servers are migrated between physical host servers. Sanbolic's Melio clustered file system addresses a shortcoming of virtualization across all major platforms - an inability to share application data between multiple virtual machines, which creates an inflexible storage platform for virtual data centers.

"Previously, a SAN storage volume containing application data had to be assigned uniquely to a single physical or virtual server, limiting flexibility and providing a single path to application data," said Momchil Michailov, Sanbolic's founder. "Sanbolic's Melio file system (Melio FS) enables multiple paths to the data and concurrent read/write access to the application data using a high performance, low latency SAN storage fabric. Shared access to application data on SAN storage infrastructures enhances application availability, and also provides flexibility to scale applications and improve performance of tiered applications."

"We are building a VMware-based virtual environment for most of our servers," said Anders Alexandersson of GVA Consultants AB, a KBR company. "All of the physical and virtual servers have common shared storage volumes formatted with Melio FS. All of our data is placed on the Melio FS formatted volumes, and we can dynamically add both physical and virtual machines to access the data. This kind on infrastructure not only significantly reduces our administrative costs, but also allows us to keep a single set of the data and increase the processing times significantly."

Sanbolic's Melio clustered file system and LaScala volume manager are designed to support Windows applications which benefit from central administration of a large virtual storage pool simultaneously accessed by multiple physical or virtual servers. Melio FS uses 64 bit architecture, allowing very large volume and file system sizes. These products install easily on physical or virtual servers, and can utilize any fibre channel or iSCSI storage hardware. Windows directory, reporting, and clustering features are supported. Reporting on storage I/O and transaction performance facilitates optimization of storage intensive workloads. The file system also incorporates quality of service assignment to allow prioritization of defined workloads in storage bandwidth-constrained environments.

Sanbolic will initially make the application solution available for Windows virtual machines running on VMware ESX, creating an even more robust, dynamic and automated data center through shared access to data. Key benefits include:

  •     Multiple paths to application data for availability
  •     Multiple virtual servers to run the same application using the same data for scalability
  •     High performance shared data for multi-tier applications. For example, multiple virtual servers can write data to a shared volume and be made immediately available to the web via multiple web servers sharing the same volume
  •     A Melio formatted volume can be accessed by virtual machines running Windows, or by physical servers running Windows, or both

Sanbolic software currently supports Microsoft Windows XP, Microsoft Windows Vista, Windows 2000 Server, Windows Server 2003 R2 and Windows Server 2008. Sanbolic distributes its product solutions worldwide through a network of distributors, OEMs, VARs and system integrators.

Sanbolic will be exhibiting this solution at the Microsoft Worldwide Partner Conference in Houston in Houston July 8-10 and at VMworld 2008 in Las Vegas September 15-18.
