Virtual Desktop deployments can bring important benefits in desktop management, security, and flexibility to support “bring your own device” policies; however large VDI deployments are very dependent on storage performance. VDI deployments are frequently derailed by cost, complexity, limited scalability, and performance issues associated with legacy storage architectures.
Enterprise deployments of Citrix XenDesktop and XenApp desktop and application virtualization utilize Provisioning Services (PVS), to centrally create, manage and deliver desktop and server OS images (vDisks). However, this “centralized” platform also introduces a single point of failure. Traditional solutions for enabling PVS HA introduce additional data and storage management overhead, single points of failure, and have no scale-out capability resulting in inefficient storage utilization that increases deployment cost.
The Melio Solution
Melio provides a resilient, scalable platform for creating, managing and delivering desktop and server OS images at a fraction of the upfront infrastructure and ongoing management cost of alternative storage architectures.
Melio enables PVS high-availability by, consolidating and storing OS images on a shared storage accessed by multiple PVS servers simultaneously thus enabling availability, scale-out, streamlined image maintenance and storage management, and a 50-75% reduction in storage requirements. In addition Melio provides a very cost effective solution for clustering XenDesktop and XenApp PVS SQL Server configuration databases for high availability, critical to ensuring full system management and functionality.
Melio is deployed in hundreds of large enterprise and government VDI installations across the globe.
With Melio, Citrix VDI customers realize an accelerated deployment timeline with less effort and upfront cost and achieve dynamic scale-out into the thousands of virtual desktops with significantly lower storage capacity requirements. Deployed with PVS, Melio offers enhanced performance, increased availability and reduced per-seat storage cost.
