| Outing blind spots in the virtual realm Virtual servers help data centers provide more resources on demand, but they also create a bit of a blind spot for IT managers responsible for network and application performance across the virtual environment. 7 tips for succeeding with virtualization As server virtualization projects gain scale and strategic value, enterprise IT managers must move quickly beyond tactical approaches to achieve best results. Seven things that will sink virtualization Many IT professionals measure the success of a technology deployment by all the things they did (see "7 tips for succeeding with virtualization"), but some say a successful virtualization implementation often can be the result of things IT didn't do. Best practices save cash, staff time when managing virtual systems The benefits of virtualization won't come easy, according to research that shows IT organizations investing time and effort into adopting best practices around managing virtual systems are more likely to lower administration costs, speed problem resolution and improve uptime across the environment. Managing the virtual realm Managing virtual servers requires IT managers to think outside the box - literally. System administrators trained to check the health and availability of physical servers now must figure out how to distinguish between what's happening at the physical level with what's going on in the virtual realm. Obviously, they must understand the many facets of virtual servers. Then they must couple that with knowledge of how to fine-tune each virtual machine as it resides with others on one hardware box. Simply put, running a virtual server environment calls for a new management mind-set, says John Hinkle, CIO at Trans World Entertainment, the Albany, N.Y., operator of retail music stores, such as Strawberries, Coconuts and FYE. Managing your VMware environment in four simple steps When it comes to managing virtual server environments, two distinct camps have emerged. One side argues that virtual machines require the same care and feeding as their physical counterparts, just multiplied by 100 because VMs proliferate at a faster pace. The second camp contends that VMs introduce new, unique challenges not before seen in the physical realm. Managing the virtual world CA earlier this week became the latest management vendor to roll out tools to manage virtual server environments, joining BMC Software, IBM/Tivoli, Opsware and others rushing to fill this important need. Virtual goo Virtualization is a superhero among technologies, transforming static, brittle data centers into dynamic, flexible resource pools and giving IT an easy way to cut costs, improve services and expand operations beyond the limits of the physical world. With great power, however, comes great responsibility. CIOs not confident managing virtual servers A majority of CIOs consider managing their virtual server environments a critical priority, but more than half aren’t confident they are doing it effectively, survey results show. No pain, no gain when it comes to managing virtualization Virtualization is the darling of the technology industry right now, but more and more industry watchers are warning IT managers about the dangers of taking x86 server virtualization too lightly.
