Fast fixes for three remote connectivity problems
Some of the most common remote connectivity problems -- VPN access, latency and bouncing connections -- have simple solutions that just take a little bit of planning on IT's end. Using a multi-entry VPN and doing a network assessment at the outset of your VDI deployment helps reduce connection problems. Read Now

Narrow the connectivity variables
Virtual desktop connectivity issues crop up for a variety of reasons, but you can use the process of elimination to limit the number of variables that could be causing problems. For example, if you can confirm that a user's hardware isn't the source, you won't waste time troubleshooting it. Read Now

Got terminal server connection problems?
If you're seeing connection refusals, check your registry key. Microsoft makes it so five fewer connections than your max will make the cut in an effort to reduce the resources that connections can consume. For example, if your max number of connections is 100, only 95 will go through. Read Now
Editor's note
With so many moving parts in VDI deployments, it's easy for things to go wrong. Problems with remote connections, storage, management and latency can keep your to-do list full.
Fortunately, there are some easy ways to avoid common issues in virtual desktop infrastructure (VDI) environments in the first place. And if you made some missteps setting up your deployment that resulted in problems staring you in the face right now, never fear. We've got troubleshooting tips for some of the most common VDI woes.
1Management and storage
Avoiding storage and management issues should start in the planning phases of VDI. You can't throw a virtual desktop at every user in your company, because not all use cases and job roles fit with VDI. Additionally, you can't guestimate how much storage you'll need or base the math solely on the number of virtual machines (VMs) you plan to deploy. If you're already looking down the barrel of a storage nightmare, however, consider monitoring, solid state drives and profile management tools to get back on track.

Who should use VDI?
One of the first things to consider with VDI deployments is which users are good candidates. If you have a call center or a customer service department where all the users can have the same desktop, then VDI will probably be a good fit. But your power users probably won't love VDI and they'll consume a lot of back-end resources. Read Now

Taking patch management from physical to virtual
Transitioning from physical to virtual desktops can cause disruptions in patch management, so when you plan and deploy VDI, it's a good idea to take patch management strategies into consideration. If you use persistent VDI, patching is pretty much the same as with physical desktops, but things get tricky with nonpersistent desktops. Read Now

Solving storage struggles
Solid state drives are another layer to manage, but for some VDI shops they can really help reduce storage bottlenecks and improve performance overall. You could also virtualize storage or cache data locally, but start by looking at whether you've overloaded your SAN with VMs. Read Now

Count 'em: 16 options for user profile management
Managing user profiles can be a challenge, but there are so many tools out there to help you. Major vendors offer robust, easy-to-use tools, and there are even more lesser-known tools, a handful of which are free. Read Now
2Latency and bottlenecks
Latency can make VDI hellish for users, which in turn means lots of requests for help from IT. When you're planning your VDI deployment, bring in the networking engineers to get their perspective, and make sure users know how and when they can access their virtual desktops -- and from which devices. Select the right remote display protocol and look into tools to improve WAN performance and optimize bandwidth.

Low-latency dreams
Do you know the many causes of latency? They include users connecting from the Wi-Fi at an Internet café or using the 3G on their devices. To reduce these latency issues, put policies in place about how and from which devices users can connect to their virtual desktops. Read Now

How distance, bandwidth and latency affect VDI
If you're looking to push VDI out over your WAN network, consider how bandwidth, distance and latency can negatively affect performance. You'll want to use the right remote display protocol, as well as companion technologies to maximize WAN performance. Read Now

Bandwidth optimization solves (some) VDI limitations
Even with improved protocol performance and better compression, the major limiting factor of VDI is bandwidth. But with bandwidth optimization, you can reduce unnecessary traffic without buying more bandwidth. Just make sure you do your research before selecting optimization technologies -- they can be complex and hard to use. Read Now
