Add Seamless Scalability, High Availability and Simplified Storage Management to Citrix Virtual Solutions with Sanbolic Melio 2010 

Hi, my name is Andy Melmed and I am the Director of Enterprise Solutions for Sanbolic Inc., a developer of software products designed to simplify, share and extend the capabilities of SAN storage.

As a new guest blogger on the Citrix Community blogs, I plan to use this forum to explain how Citrix ISVs, VARs and customers around the globe are enhancing Citrix virtual solutions with virtual shared storage provided by Sanbolic. In my blogs, I’ll cover a wide range of topics that focus on using our software to improve the scalability, availability, flexibility and manageability of Citrix virtual solutions, including new product features, configuration best practices and recommendations, infrastructure design options, etc. I will also include references to newly published white papers and configuration papers to make sure you have the latest information on how Sanbolic is helping organizations realize the greatest return on their investments in Citrix technologies.

For my first posting, I’m going to explain how Sanbolic’s flagship product, Melio 2010, enhances Citrix XenDesktop virtual desktop and XenApp application delivery infrastructures powered by Citrix Provisioning Services (aka PVS). To begin, I’d like to pose the following questions:

Are you currently in the planning and design phases of deploying a virtual desktop and/or application delivery infrastructure using XenDesktop and/or XenApp?

Are you planning to take advantage of the performance, scalability and reliability capabilities of SAN storage to store the virtual images (vDisks) that will be streamed to virtual machines hosting desktops and XenApp servers?

Are you spending a lot of time looking for the best way to ensure these infrastructures achieve the highest levels of performance, scalability, availability and manageability in order to realize the greatest return on your investment?

If you answered “yes” to one or more of the above questions, I strongly recommend taking a few minutes to read the following white paper:

This paper highlights the storage options most frequently considered by organizations looking to enable high availability for Provisioning Services (the underlying technology used to stream desktop and server OS images on demand to virtual machines hosting virtual desktops and XenApp servers).

Once you’ve finished reading the paper it will be obvious why, out of all the options available for enabling high availability for Provisioning Services, only Sanbolic Melio 2010 actually enhances Citrix XenDesktop and XenApp!

The following diagram illustrates how Sanbolic Melio 2010 integrates into a XenDesktop virtual desktop infrastructure:

Organizations that have deployed XenDesktop and XenApp with Sanbolic Melio 2010 have achieved the following:

1. Simplified maintenance of vDisk images by consolidating all vDisks onto a single volume on SAN storage, with all vDisk changes available for streaming by multiple PVS Servers immediately, i.e., no need to replicate the vDisks to different PVS Servers to ensure vDisk version consistency.

2. Enhanced I/O performance using stripe sets (comprised of disks from multiple storage arrays) that leverage multiple storage controllers, caching and spindles to improve the user experience.

3. Quick and seamless scale-out by adding more PVS Servers or more storage resources on the fly, with little effort and no interruption to user productivity.

4. Reduced storage costs through greater utilization of storage resources.

5. Centralized management of storage resources as all physical disks are virtualized and managed from a single console that can be accessed locally or remotely.

6. Improved fault-tolerance via high availability of PVS vDisks and databases.

7. Enhanced vDisk protection with cluster-wide or individual vDisk snapshots.

Compatible with all industry-standard server and storage hardware, Sanbolic Melio 2010 runs on Windows Server operating systems, allowing multiple PVS Servers to share concurrent read-and-write access to a single volume on SAN storage that contains the vDisks and optionally, device write cache files. This configuration enables high availability of PVS vDisks to ensure maximum uptime for virtual desktops and XenApp servers as well as high availability of PVS databases, enhancing system fault-tolerance.

For mid- to large-size XenDesktop and/or XenApp infrastructures, only highly scalable and highly available shared storage provided by Sanbolic Melio 2010 and SAN storage offers the levels of performance, scalability, flexibility and manageability necessary to meet both current and future demands while allowing organizations to achieve the greatest return on their investments in these industry-leading solutions.
