So you are a loyal VMware customer. You have licenses for vSphere 4 and you are about 40% virtualized. Based upon the revised vRAM entitlements in the revised vSphere 5 licensing, you think you are going to be OK as you progress through the more demanding business critical purchased and custom developed applications that lie in front of you. Continue reading vSphere 5 Licensing – The Role of Cross Platform Management Tools and the Hotlink SuperVISOR
As a delegate for Tech Field Day 6 in Boston, I was introduced to several virtualization and performance management tools from vKernel, NetApp, Solarwinds, Embotics, and a company still in stealth mode. With all these tools and products I noticed that each was not integrated into the roles and permissions of the underlying hypervisor management servers such as VMware vCenter, Citrix XenConsole, or Microsoft System Center. This lack of integration implies that a user with one set of authorizations just needs to switch tools to gain a greater or even lesser set of authorizations. This is not a good security posture and in fact could devolve any security to non-existent. Continue reading Centralized RBAC Missing from Virtualization Management Tools
Monitoring computing infrastructure and applications for capacity, availability, and performance is a business that has been around for a long time – in fact for just about as long as computers have been used for business critical applications (since the mainframe lead era of the 1960’s). Since that time several waves of change have swept through the computer industry, and with each wave of change has come new computing architectures, new applications, requirements for monitoring and new monitoring approaches. Those waves have included mini-computers, personal computers, LAN based file sharing, client/server based computing, Internet (browser) based computing, N-tier SOA based applications, and now include agile development, virtualization, cloud based computing, and the proliferation of mobile based applications.

On January 12 2011, NetApp announced that it is going to acquire Akorri. The significance of this can only be understood by first going through some background on Akorri.
Akorri was founded in 2005 by Rich Corley, a serial entrepreneur. Rich has a very deep background in storage and in particular in how storage performance impacts the performance of workloads that rely upon storage systems. At the time of the founding virtualization was not the overwhelming phenomena that it is today and the focus of Akorri was upon understanding how the intersection of storage performance and the performance of the rest of the infrastructure (servers and networks) impacted the performance of the overall system. Continue reading NetApp to Acquire Akorri
John F. Kennedy, the 35th President of the United States once said that “A rising tide lifts all boats”. This was in reference to a strong economic growth, which benefits most if not all participants in that economy. While the entire economy has not be exceptionally strong of late, companies related to the virtualization technology sector have been chalking up increasingly strong results. For Q1/2010 here are some recent revenue and earnings reports: Continue reading A Rising Tide Lifts all Virtual Boats
The Cisco-VMware-NetApp (CVN) was discussed on the Virtualization Security Podcast as it pertains to Secure Multi-Tenancy (SMT). This is a major concern that was also discussed at RSA Conference 2010 within the Cloud Security Alliance Summit. The question still remains how to achieve this goal however. CVN is a very good start, but as we discussed on the podcast is missing some key elements listed below:
- How to define and identify of the various administrator roles: Application Admins, IaaS Administrators, and Cloud Administrations. Continue reading Cisco – VMware – NetApp an Interesting Approach to Secure Multi-Tenancy
