There has long been a debate about testing products within a virtual environment. Not just on how, but the why as well as the what to test. There are limits in some EULA’s as well on the reporting of such testing. This was the subject of the 7/25 Virtualization Security Podcast (#112 – Virtualization Security Roundtable) held Live from NSS Labs in Austin, TX. Where we delved into the issues of testing within a virtual environment. While the discussion was about security products, it is fairly straight forward to apply the concepts to other products within the virtual environment.

Data Protection and patch management of virtual desktops, while not a sexy topic, is one that should happen on a regular basis within any organization implementing or working to implement virtual desktops. Recently, we have been testing virtual desktop software and there is a huge difference between patching and protecting data in a small number of instances and 1000s of instances. There are scale considerations as well as ease of use for file level and system recovery as well as issues with patching virtual desktops (not to mention other security issues).
Atlantis Computing have released the first in-memory storage solution for persistent VDI. Setting aside the remoted experience, peripheral support, licensing and off-line access – the most nemesising nemesis for VDI is hardware scale. A major hardware limiting factor is storage performance.
In a transition from physical PCs to virtual work spaces you can move 50,1000,20,000 people from an environment where everyone has their own hard drive in their own device, to a shared environment where there are (hopefully) no longer 50,1000,20,000 hard-drives. You do this to achieve cost savings. Still, in the majority of instances, the desktop file system and the apps that run on it weren’t designed to understand such consolidation. Many a desktop project fails because the storage infrastructure wasn’t architected with these mismatches in mind.
Yet, desktop virtualization solutions have have matured to accommodate such issues. A range of increasingly impressive VDI appliances: dedicated drive arrays. Way back in 2010 we were reporting that Atlantis Computing were looking to Transform Desktop Computing with their In Line Image and Optimization (ILIO) product. Atlantis Computing’s core ILIO product sought to address optimizing non-persistent VDI instances, then offered a RAM based solution with their ILIO DiskLess VDI, then presented a way to optimize Citrix XenApp instances. Atlantis’ offerings look to dramatically reduce the physical hardware required to support virtualized desktop infrastructures.
And now to their portfolio, Atlantis Computing add ILIO Persistent VDI 4.0. Some early stability issues aside, Atlantis have developed a strong and supportive market and expanded on it. What is in this release? If 2013 is to be the year of VDI – how does ILIO Persistent VDI 4.0 help? Importantly, will Atlantis Computing’s ILIO Persistent VDI change the game?
Participate in any virtual desktop design session and you will know that the discussion almost always moves immediately to how many IOPS per virtual desktop session should be expected. More often than not, the leader of these conversations will answer “it depends”. This is a statement that does not give most end users a warm a fuzzy feeling because it usually comes with a pretty heavy storage price tag. Unfortunately, there are many factors that affect overall performance. Within the virtual desktop session, the number and type of applications you have running, the layers of security configuration and policy that are applied, and how you are handling user personalization have an impact on IOPS. Many of these challenges can be addressed by applying good standard virtual desktop practices, which are often different from the way physical desktops are traditionally architected.
In the face of declining PC revenues and slowing storage sales VMworld San Francisco saw the launch of two new Wyse P Class Zero Clients, two new EqualLogic hybrid storage arrays and three new reference architectures optimized for VMware View, signaling a clear intent from Dell that it is getting serious about VDI.
Sridhar Mullapudi, Director of Product Management at Citrix Systems, took to the Citrix Blog last Friday to announced Server VDI is here! Deliver Multi-tenant Cloud hosted VDI desktops from the Cloud giving every appearance of being particularly pleased with himself. As well he might.
