Chad Sakac mentions on his blog that VNXe “uses a completely homegrown EMC innovation (C4LX and CSX) to virtualize, encapsulate whole kernels and other multiple high performance storage services into a tight, integrated package.” Well this has gotten me to thinking about other uses of VNXe. If EMC could manage to “refactor” or encapsulate a few more technologies, I think we have the makings of a killer virtualization security appliance. Why would a storage appliance spur on thinking about virtualization security?

In “IT as a Service Reference Architecture“, we presented a a categorization of the the functionality and the products that are needed in order to construct an IT as a Service system. Purposely missing from this architecture was the question of how to monitor the performance of the services delivered from the service catalog via the underlying policies and automation in the IT as a Service stack.
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.
When discussing Virtualization Performance Management, we separate the vendors that focus upon this area in to three groups:
- Resource and Availability Management – this group of vendors focuses upon collecting the resource utilization metrics that are made available by the virtualization platform vendors for the purposes of capacity planning, capacity management, and ensuring the overall availability of the environment. Leaders in this category include Vizioncore (vFoglight), Veeam (Veeam Monitor), VMware (Hyperic), Hyper9, Netuitive, and Zenoss.
Since the dawn of TCP/IP networks and distributed networks of Intel PC’s and Servers there have been large numbers of point tools designed to monitor and manage specific sets of infrastructure in these networks, and management frameworks from major vendors like CA Technologies, IBM (Tivoli), HP (OpenView and the follow on products) and BMC that were designed to manage the entire network. The frameworks were focused first and foremost on the availability of the hardware that comprises these networks, and have grown over time to look into network utilization and performance as well as resource utilization of servers.
Virtualization (the underlying foundation of a cloud) introduces a set of challenges to how one should monitor the performance of the infrastructure and the applications. These challenges are:
- Unlike physical systems that are mostly dedicated to specific applications, virtual systems are both shared and dynamic. This makes inferring the performance of the infrastructure by looking at resource utilization statistics ineffective. Leading edge Infrastructure Performance Management vendors like AppFirst, Akorri, CA|NetQos, Virtual Instruments and Xangati are taking an Infrastructure Response Time approach to this problem that avoids the issues of relying upon resource metrics, and provides a true picture of how the infrastructure is actually performing.
