Storage is, in many respects, the Achilles Heel of the virtual world. Many virtual moves will “stall out” at around 20% of data or storage moved as I/O usage and storage issues begin to crop up and IT techs will often find it frustrating to deal with SAN and other storage media via a remote connection. Often, what will happen in a virtualized environment is that problems on the network will be detectable but not easy to locate. This results in frustration for both the employee and management pool in general as well as IT staff, as they are expected to create solutions with very little in the way of tools to do so.
As the VPS industry evolves, what is being called for from IT professionals is a set of tools that are more robust and more end-to-end when it comes to SAN storage and virtualized networks. Visibility tools are a good example – IT techs want to have a better way to both see and understand problems that are going on in the network and also be able to more easily identify them. These problems can run the range from I/O usage issues as multiple servers on the same machine each follow their own usage pattern, or backup crashing issues as the draw on I/O resources becomes too heavy.
A number of companies are now developing SAN tools that will allow the IT sector better control over their storage space. Whereas older systems permitted a physical inspection of servers for problems, new systems must include a way for users to address problems remotely and without the ability to actually see the issues occurring. Greater numbers of SAN tools mean a greater market penetration for VPS systems.
