With the prevalence of mobile devices connecting people and things today, we are seeing a base expectation for uncompromised wireless connectivity. There is no doubt that the trend for high performance, pervasive wireless is on the rise and will continue for the foreseeable future. We at Cisco strive to help organizations get ahead of these trends with solutions that can be deployed with confidence today. That’s why I am proud to announce the latest Cisco Wireless Release 7.5, the third feature-rich release we’ve had in the last 12 months.
Release 7.5 enables mission critical wireless deployments with sub-second stateful failover for wireless clients, wire-like Gigabit performance with the 802.11ac Module, and a bevy of other features.

Virtualizing Oracle Databases – The Time Has Come!
Overall, virtualization of IT applications and databases is quite pervasive. Estimates from industry analysts show that some applications and databases have virtualization penetration rates of 80 to 90%. Overall the estimates for datacenter virtualization range from 60 to 70%. One curious exception is the rate of virtualization for Oracle Databases. Some estimates put the Oracle Database virtualization rate below 20%. The big question is why so low for Oracle Database?
While I have never seen any formal research documenting the reasons, ad-hoc discussions with many DBAs and Architects and other Oracle users indicates that some of the major reasons for their reluctance to virtualize include:
Fear of performance degradation
Concern over availability and stability
And an “If it ain’t broke, don’t fix it” view
And for mission critical Oracle Databases those are valid concerns. Any outage or performance degradation is costly. Status quo is the safest approach. But what I am hearing from customers and the Oracle community at large is that the time has come for virtualization. The improvements in configuration flexibility, reduced deployment times, dramatically improved disaster recovery and cost savings are great motivators for virtualization by themselves. One of the early adopters for virtualizing and Oracle infrastructure was EMC. lets hear what EMC’s Chief Database Architect, Darryl Smith, has to say about the benefits of EMC’s virtualization efforts with EMC’s Oracle Infrastructure.
So EMC found great performance, improved availability and a reduction in database licenses all because of their move to virtualize their Oracle infrastructure. Here is more of Darryl talking about Oracle virtualization and the cloud.
EMC took the next logical step from initial virtualization and moved their Oracle infrastructure to a full cloud implementation with even more benefits thanks to the improved Oracle workload mobility.
EMC is a great example of why there appears to be a growing tide of Oracle users who are ready to ride the wave of virtaulization. To learn more about EMC’s virtualization efforts and results, these two whitepapers on Cisco.com will provide a more complete overview of their journey:
Say you were on an advisory board for a city where population growth, traffic congestion, and demand for services (ambulances, police, & firefighters) presented major challenges, what actions would you suggest the city to take? Similarly, say you were managing IT operations for your company, what actions would you put in place to respond to the Bring Your Own Device (BYOD) trend and the potential impact on your network as users flood it with tons of iPads, Ultrabooks and other personal devices?
Before you rush out of the door to take action, you may want to ask yourself two questions:
- Is my action plan going to deliver a consistent and high quality user experience?
- Is my action plan sustainable, given the demand, available IT headcount and budgetary resources?
Importance of High Availability: If you are reading this blog, you likely own 2-5 Wi-Fi-capable devices: laptops, mobile phones, or tablets. From employees to students, from doctors to guests, the common theme is that everyone now uses wireless as a preferred mode of access.
