Solving the VDI Performance and Cost puzzle with Datrium RackScale for Citrix MCS and PVS

I am happy to announce that Datrium is now certified as Citrix Ready® and the solution is readily available in Citrix Ready Marketplace (here).

The Citrix Ready program helps customers identify third-party solutions that are recommended to enhance virtualization, networking and cloud computing solutions from Citrix. As part of the program, Datrium has completed a rigorous process to ensure its Open Convergence platform, Datrium DVX Rackscale is compatible with Citrix XenDesktop®.

Citrix XenDesktop and Datrium DVX combine to provide a platform for simple administration, high performance, server choice flexibility and cost-effective scaling of virtual desktop deployments.

Datrium DVX integrates CPU and flash performance on hosts with desktop-centric, efficient, and scalable data management tools to enable Citrix administrators to effortlessly provision virtual desktops, accelerate applications, and protect and recover virtual desktops.

Datrium DVX separates on-host IO performance from off-host durable data, so speed and persistent capacity can each be provisioned independently, efficiently scaling resources with the addition of new compute or data nodes. The separation of data between the host active data and durable copy allows each host to remain stateless and to operate independently from the others, allowing for better resource isolation and overall availability. More detail on the architecture is in this white paper.

More specifically, when looking at Citrix provisioning mechanisms, PVS and MCS, Datrium help in reducing the total cost per desktop, enhance security with end-to-end encryption, provide effortless management, increase performance and implement business continuity for Citrix servers and dedicated virtual desktops.

 

  • Bring Your Own Server

    – An organization may obtain new servers from Datrium or from their preferred vendor, or they may use existing servers that are not quite ready to be retired. No hardware vendor lock-ins.

  • No HDD Requirement / Minimal SSD

    – In VDI deployments Data Avoidance and Reduction ratios are very high granted that virtual desktops are exact copies of each other, and large storage capacity is not a great need for the actual desktops. Datrium requires just enough Flash capacity on each desktop host for the de-duplicated active working set, eliminating unnecessary storage components from servers, reducing costs, and making them stateless. This strategy benefits MCS deployments, but also brings the data services, simplicity, and virtual desktop acceleration to PVS deployments, while keeping costs under control.

  • Data Optimization

    – Datrium DVX natively implement data avoidance techniques like zero cloning and VAAI support, coupled with data reduction methods like deduplication, compression and erasure coding. For MCS provisioning, the end result is extra capacity for durable data and additional performance for active data on servers. PVS deployments also benefit from performance for active data on servers.

  • End-to-End Encryption

    – Rest easy that the whole enterprise data is protected from network sniffers with AES-XTS-256 end-to-end software encryption (at-host, in-flight and at-rest) without any performance hit to your end-users’ experience; for both MCS and PVS.

  • Data Locality

    – Data locality provides increased performance for Read IOs maintaining all active data blocks belonging to virtual desktops on Flash in the servers where the desktops are currently running, vastly helping MCS deployments.

  • Write Cache Placement

    – For Citrix PVS deployments Datrium DVX address management and placement of the Write Cache, making it straightforward and easy, providing a single convenient datastore across all servers in a cluster.

  • Citrix Business Continuity

    – Datrium DVX has critical data protected with snapshot, cloning, and elastic replication to ensure virtual desktops are protected locally and off-site for blazing fast recovery. For MCS deployments Datrium DVX protect both servers and dedicated virtual desktops; for PVS, servers are fully protected.
