Architecting the Multi-Purpose Data Lake with Data Virtualization

whitePaper | April 27, 2022

As virtual environments scale, understanding how each virtual machine impacts the underlying infrastructure becomes a necessity for efficient data center design and timely issue diagnosis. Capturing this information, however, typically requires complex and costly manual processes. These issues are often particularly challenging across the network, generating a “fog” that hides data congestion and impedes identifying a resolution.

Intel Page Modification Logging (PML) is a novel hardware feature for tracking virtual machine (VM) accessed memory pages. This task is essential in today’s data centers since it allows, among others, checkpointing, live migration and working set size (WSS) estimation. Relying on the Xen hypervisor, this paper studies PML from three angles: power consumption, efficiency, and performance impact on user applications. Our findings are as follows. First, PML does not incur any power consumption overhead. Second, PML reduces by up to 10.18% both VM live migration and checkpointing time. Third, PML slightly reduces by up to 0.95% the performance degradation on applications incurred by live migration and checkpointing.

Satellite networks offer their customers several advantages over other types of connectivity. They are easily deployed, reliable, and allow a wide degree of mobility, making them a perfect fit for Disaster Recovery Plans (DRP). They are an essential asset in places where other connectivity methods are not available, such as oil rigs, vessels, or even planes. However, they have several characteristics that make them harder to manage when compared to other kinds of networks. This document will discuss those challenges and explore how the Versa Operating System (VOS™) can help you extract better performance out of your Satellite links.

The need for organizations to change to meet evolving business environments is not a new concept. However, what is new in our current moment is the pace of change. Organizations across all industries now have to adapt to a rapidly evolving IT and application environment. These changes have been accelerated by a global pandemic that is forcing employees to work remotely and by the adoption of modern applications that are distributed across corporate data centers, multiple public clouds, and increasingly, edge locations. Unfortunately, both of these efforts create more IT complexity.
